Description of the Invention: [Technical Field of the Invention] Described herein is a method, apparatus and system for arsenic galvanizing of an object. More specifically, what is described herein is a < 1 blade long object (for example, an object having a longer length than the width or diameter), such as, but not limited to, a metal strip, A galvanizing method, apparatus or rod for wires, rods or tubes. [Prior Art] The plating is to apply a protective zinc coating to the iron or steel body to reduce the repulsion: the method 'which helps to extend the useful life of the object. Corrosion is the reaction of materials ^ ^ , , and exemption, especially oxygen. Corrosion can be defined as the ability of the material to resist oxidation and aging. Zinc plating is important for the durability of plating on objects that are subject to deterioration in the surrounding environment. The galvanizing process consists of a gold buttoned drawer coated with a thin protective zinc layer... (4) Metals such as iron and steel. The zinc layer provides protection to the metal against corrosion. (4) You are resistant to corrosion. The zinc protective layer prevents the iron-containing material from being used? Pick up the oxidized oxygen contact. The zinc film, the oxidized film with "zinc:: has a naturally occurring oxygen corrosion resistance. (d) to avoid corrosion so that it has several ways of galvanizing the object, the shovel shovel cobalt D, but not Limited to hot dip zinc [electrically recorded zinc, mechanical coating, zinc spray - or more VT" powder coating. Any of these methods can be operated by a continuation process, two: =. For example, 'hot finished products. Or 1 individual raw materials are opened... in the bath and connected to e i Μ.,,, and galvanized is immersed in the zinc wei·1 picker. Typical immersion ..., and plating method, regardless of whether it depends on 201242676 continuous or static mode operation, may involve one or more of the main province ^ 歹 1 processing steps: / month 4, pickling, fluxing flux , galvanized, cold * Μ ^, 7 P ' / 闰 及 and inspection, at the same time throughout the process 矸 φ ^ first person rolling. In the cleaning step, a hot alkaline cleaning agent such as a lead bath type, or ..., a fertilizer water is removed to remove the surface residue to rinse the object to remove the cleaning residue and/or may be removed prior to pickling. Plate recognition & Use a rat knife to remove extra water or excess residue. In the pickling step, the surface rust or scale is removed by using diluted hydrogen acid or sulfuric acid and the surface is washed with a chemically cleaned metal surface and/or the air knife step can be used to dilute the ^J The acid concentration and/or removal of residues that may remain on the 玄d object prior to the fluxing step. During the soldering step, the object is immersed in a liquid state flux to remove oxides and prevent oxidation prior to the galvanizing step. An example of a liquid flux used in this U Shao Shaojia is a gasification ammonium solution that aids the ability of zinc to adhere to the surface of the object. During the zinc bonding step, the object is immersed or passed through at a likelihood of 'for example', about 437.5. 〇: A bath of molten water to a temperature of about 45 generations. At this temperature, the molten zinc adheres to the surface of the object to provide a layer whose size is determined by the length of time between contact of the object with the molten zinc. After the zinc bonding step, the object is decorated and cooled. During the retouching step, excess zinc is often removed by exclusion, centrifugation, and/or rubbing of the object. The object is often cooled using a chiller unit and/or a high pressure air knife using nitrogen during a certain period of the finishing step or just after the finishing step. The galvanized object is then inspected to ensure that it meets one or more of the following criteria: tensile strength, yield strength, hardness, elongation, stress/strain, 4 201242676 . Open v shape / condition / thermal conductivity, resistance, coating Cover weight and / or specifications, appearance and its 'and 〇. With regard to appearance, the object can be inspected to ascertain one or more of the following (which may not be required depending on the application): dull gray color, rust, blistering, roughness, excess thickness, agglomeration and Vertical flow, small protrusions, bare spots and/or wet storage stains and massive white deposits. In addition to the considerations on the raft, what we want is the zinc method of the mine, especially for long objects such as wires or tubes, in addition to the following desires or evenings. Round and uniform surface coating, brighter The controllability of the surface finish, coating thickness or gauge, higher production speed or throughput and/or reduced amount of zinc used in the process. The surface coating that we want to obtain a round and uniform hook for the surface of the metal object, especially the wire or the official'. The problem often encountered in the method of melting zinc sen is related to the roundness and uniform coverage of the coated surface of the rod and the wire, especially for the horizontal coating system. Uniform coating 1. All points must have the same linear properties (ie corrosion resistance, diameter, etc.). The appearance of the surface finish is both bright and shiny. Most desirable to the user; ^ coating thickness control. Different applications such as the different zinc wire and rods require different coating thicknesses. We intend to allow higher production speeds and throughput for this (4) method. Finally, this technique necessitates saving or reusing zinc during the coating step to reduce overall manufacturing costs. Accordingly, there is a need for improved recording methods and apparatus for objects that meet one or more of the foregoing objectives, such as for galvanizing a long object such as a metal strip, wire, rod or tube. SUMMARY OF THE INVENTION 5 201242676 The method, the S-book and the system meet the above objectives in the following manner. The method and apparatus described herein can provide an alum zinc surface finish that is achieved by less oxidation of the surface at elevated temperatures than prior art methods involving air cooling. The method and apparatus described herein provide a squeezing I" "the 栻 system is intended to provide the desired zinc coating thickness. The method and X preparation described herein can be used to improve the cooling of the long object, such as a wire rod or tube. Increased productivity and preheating temperature can be reduced while still achieving good results. Furthermore, the methods and apparatus described herein can remove excess zinc from the wire or rod through the nozzle to reduce the cost of zinc use, so if necessary The excess zinc is then collected and reused. In one aspect, a third object for processing a long object containing a molten coating is provided, comprising: a nozzle comprising: a nozzle opening; defining the passage of the long object a first volume of the inner compartment; defining a second volume of the outer compartment in fluid communication with the nitrogen source, wherein the gaseous nitrogen passes through the second volume at a pressure and a temperature and is disposed adjacent the nozzle opening and contacts the elongated object; A general tube comprising: a porous inner compartment defining a third volume; an outer compartment defining a fourth volume wherein the fourth volume is mixed with one or more nitrogen containing gaseous and liquid nitrogen The input device is in fluid communication; and a temperature sensor for monitoring the temperature of the nitrogen mixture, wherein the temperature sensor is in electrical communication with the programmable logic controller. In another aspect, 'providing a length for processing a molten coating The method of the object includes: causing the long object to be guided to direct and remove excess nitrogen from the surface of the object; and to apply the long object to rapidly cool the long object and make the long object The concept of solidification of the coating; wherein the nozzle comprises a nozzle opening; an inner compartment defining a first volume through which the long object passes; a second volume outer tank defining fluid communication with the nitrogen source, wherein the gaseous nitrogen is Pressure and a temperature pass through the second volume and are disposed adjacent the nozzle opening and contacting the elongated object; and wherein the conceptual tube includes a porous inner compartment defining a second volume; an outer compartment defining a fourth volume, wherein the fourth a volume in fluid communication with one or more input devices for a mixture of nitrogen containing gaseous and liquid nitrogen; and a temperature sensor for monitoring the temperature of the nitrogen mixture Wherein the temperature sensor is in electrical communication with the programmable logic controller. [Embodiment] In the specific implementation of the invention exemplified in the description of the figures, specific language will be used for clarity. However, the invention is not intended to be limited The specific language of the invention is to be construed as the invention It should be understood that the present invention is not limited to the specific embodiments described in detail herein. The method and apparatus are combined with gaseous nitrogen (gan) and low temperature liquid nitrogen (LIN) to remove from a long object surface such as a wire surface in the following manner. Or wiping off excess molten zinc (Zn). It is known that in the method of atomizing molten metal, which involves the same phenomenon and principle as zinc wiping, the high temperature of the atomizing gas retains the pure viscosity of the metal and the high gas. Viscosity improves the shear of molten metal. Salt also believes that the use of warm or room temperature gas may (iv) use low temperature or cool temperature gas ' However, the zinc surface of the steel wire that has just been wiped must be cooled (and solidified) as soon as possible to provide the expected productivity and quality improvement. The method and apparatus described in the above-mentioned No. 201242676 satisfy these contradictions by removing (removing) excess molten metal, such as zinc, by room temperature gas, and then rapidly solidifying the thinner zinc coating in subsequent manufacturing steps. Demand. Moreover, the method and apparatus described in some embodiments may control the thickness of the zinc coating not only by adjusting the opening of the front side (wiping) opening of the apparatus but also by controlling the temperature of the gas. In various embodiments, the method and apparatus satisfy the aerodynamic-based retention of the axial position of the line during the atomization section and the quench section of the line warp wiping apparatus to satisfy the line wiping field Another challenging need. The galvanized wire is susceptible to vibration and may eventually become unusable if the wire accidentally touches the inner diameter surface of the device. The apparatus described herein applies one or more of the following forms: a perfectly cylindrically symmetric gas opening around the line, a microporous tube wall around the line that ensures the axial position of the line, and/or any line in the line Other gas openings that follow the pattern of concentric gas emissions. The dynamic pressure of the exhaust gas causes the line to float at the shaft position and minimizes the risk of contact between the line and the equipment that may result in a failure. Thus, in some embodiments, the methods and apparatus described herein operate in a horizontal position and in a more commonly used vertical position. In this way, the end user feels more freedom in rebuilding their wire galvanizing system without further concern about the gravitational force acting on the wiped wire.

Figure 2 provides a side view of a concept tube 200 that can be used in conjunction with the galvanizing method, apparatus or system described herein. In one or more embodiments herein, the nozzle and concept tube 8 201242676 depicted in Figures 1 and 2 are secured together by a nozzle retaining plate 180 as shown in Figure 3. However, in other embodiments, the nozzle 100 and the concept tube 200 are detachable. Moreover, in the particular embodiment illustrated in Figures 1 and 2, the apparatus operates in a continuous process at a level. However, in other embodiments, the nozzle 100, the concept tube 200, or both the nozzle 100 and the concept tube 200 can operate in a vertical continuous process. A long object such as a wire, rod or tube is robbed 210 through the inner nozzle chamber 160 and the inner concept tube in the direction indicated by the arrow. During operation, pre-heat long objects such as lines or rods (also not shown) before entering the zinc bath (not shown). After the long object is preheated and coated in the zinc bath, the object is passed through the nozzle 100 via an opening 110 through which an adjustable gaseous nitrogen (GAN) knife flows through a nozzle crack opening 17〇. The GAN knife 1 70 removes excess zinc coating from the surface of the object as it passes through the nozzle 100 and leaves the desired zinc coating thickness or gauge on the object. In the particular embodiment illustrated in Figure 1, the nozzle 100 has a circular cross section and has a bevel 190 adjacent the nozzle opening 110 in a side view as depicted to allow excess zinc coating to deviate from the object or line. . The GAN is dispensed through the nozzle nozzle 100 through the nozzle chamber 100 and in front of the nozzle 100 through the nozzle split opening 170. Gaseous nitrogen (GAN) is pressurized at an external source (not shown in Figure 1) and passes through one or more input devices 14 into the outer nozzle to snatch 150, where it is equalized. The GAN then emits a uniform force on the coated surface of the long object through the crack opening 1' of the nozzle 100. The flow rate and pressure of the gaseous nitrogen can range from about 5 to about 30 m3/h. In this manner, the pressurized gaseous nitrogen forms a GAN knife, and when the galvanized object passes through the nozzle opening 9 201242676 no, the GAN knife is used to remove the smelting zinc dust from the galvanized object coating on the line/ On the stick, make it ^ 'zinc. The house is then stripped of any circular coating on the line/rod that is flat on the surface area. η redundant words 'on the surface of the object, as mentioned first, 'the long object such as a line (not shown) according to the arrow of Figure 1: the nozzle 100 passing through the nozzle opening 110 through the nozzle is not in the direction 100 The following elements are included: an inner nozzle enclosure 120 that defines a long object, such as an inner nozzle chamber 160 through which the line passes;: h has an inner wall boundary for a donor fluid, such as gaseous nitrogen, to pass through the - or more input device 140 into the outer spray The outer nozzle chamber 15 such as 50 and the slit opening 170 flows out. The crack opening σ has the figure: the length 'also' shown. The length of the crack opening 17〇 can also vary from about 〇 to about 12 mm, for example about 〇.〇1 to about 12, or greater if necessary. To adjust the zinc coating on the surface of the long object to a desired thickness or gauge. The desired thickness of the coating can then be followed by selecting the "dx" value of the crack on the nozzle ι. For example, the length & the thinner the zinc coating or the coating on the smaller the object, the thinner the specification. In some embodiments, the length of the crack opening is "heart", The larger crack opening "dx" is set by rotating the outer nozzle body enclosure 13〇 clockwise and counterclockwise for a smaller "dx" crack opening. Another advantage of the nozzle i 所示 shown by ϋ i in addition to the advantages described above is that it can achieve a higher throughput. One of the bottlenecks of this plating method is the time it takes to preheat the zinc to the desired temperature. The nozzle improves the cooling rate because a uniform pressure is applied to the molten coating through the helium nozzle to obtain a zinc coating that is more uniform. The end user can lower the preheat temperature and/or shorten the dwening time in the zinc bath during the ginning step because a more uniform coating is obtained. Figure 2 provides a side view of a conceptual tube that can be used in conjunction with the methods and systems described herein. The concept tube 2〇〇 includes an inner concept tube compartment 21〇 in fluid communication with one or more multiple liquid nitrogen (UN) and/or gaseous nitrogen (GAN) input devices 220; a porous inner tube 23〇; An outer conceptual tube 25〇, the inner side wall defining an outer conceptual tube compartment 24 (wherein the inner tube 230 is passed through the innermost or inner concept tube compartment 21 when the coated object passes the direction indicated by the arrow in Fig. 2) The use of two or more concentric tubes (eg, porous inner tube 23〇 and outer concept tube 250) in which the pores are in fluid communication with the outer concept tube chamber 24〇 and the inner concept tube chamber 21〇 provides pressure drop and uniform pressure distribution. For the innermost or inner concept tank 210, in the particular embodiment shown in Figure 2, both the inner and outer tanks 21 and 24 contain the LIN and GAN provided by the mixing tubes (shown in Figure 4). The thermocouple 260 is temperature-controlled and maintained at a desired level, and the thermocouple 260 is in electrical communication with a programmable logic controller (pLC) or temperature and electronic control board (shown in Figures 4 and 5). 2〇〇 Allow the long object to “quench” through the inside, that is, the cooling is very Soon that the molten zinc solidifies immediately or nearly immediately. The inert gas in the inner chamber 21 of the concept tube 2 maintains the oxide-free surface of the long object passing through it, giving the long object a commercial desire Bright finish. The productivity is increased by pre-cooling the long object in the concept tube 200 which enhances the cooling rate. Figure 3 depicts the apparatus for attaching the nozzle.1 and the 201242676 tube 200 via the nozzle retaining plate 18. As shown in Figure 3, the galvanized object passes through a nozzle, wherein the molten coating on the object is lowered to a specified desired thickness. The object then continues into the s-concept tube 200 'where' due to the concept tube The temperature of the LIN/GAN gas in the 2 内 inner compartment 2 1 0 causes the smelting coating to solidify rapidly. The temperature of the smashing 210 can be between about 5 〇〇ς: to about 150. °C' and depending on the zinc coating. In particular embodiments where a thicker coating or gauge is desired, lower temperatures may also be desired. The desired temperature is mixed in a mixing tube at ambient temperature. LIN, usually at about -196 ° C, with GAN This can measure the temperature in the inner tank 210 or the conceptual tube 200 by the thermocouple 260 and add LIN to the GAN stream in a mixing tube (shown in Figure 4) which is then passed through one or more LIN/GAN Input device 220 flows into the concept tube. Figure 4 provides a view of the method and system described in the text including a mixing tube 410. The mixing tube 410, switchboard or programmable logic controller (PLC) 460 and LIN and GAN source assistance LIN and GAN are mixed in the mixing tube 410 to achieve the desired solidification energy in the concept tube 200'. The mixing of the LIN and GAN is performed by the PLC 460 in conjunction with the concept tube 200 or thermoelectricity shown in FIG. The input temperature measurement of the coupling 260 is controlled. The PLC 460 is controlled by adding a LIN (switching the solenoid valve 470 in the LIN delivery line) to the mixing tube 410 (where the LIN is mixed with the GAN via one or more conduits or openings 420) to achieve a set temperature. The temperature in the concept tube. The mixed LIN and GAN at the set temperature are then passed to the conceptual tube 200 via the mixed nitrogen conduit 440. Therefore, the desired temperature in the concept tube 200 is achieved by the switching of the electricity 12 201242676 magnetic/proportional valve 470 on the LIN supply line controlled by the PLC 460. In various embodiments, the GAN supplied to the nozzle for arranging excess zinc and maintaining a set thickness of the coating thickness on the wire/rod may also optionally be by the plc 460 (not shown) To control. In some embodiments, the pressure and temperature of the mixed nitrogen conduit can be monitored via any of the pressure and temperature sensors 430 and 450, respectively. Figure 5 provides another specific embodiment of the apparatus and system 5 described herein. In the system 500 shown in Figure 5, the nozzle 1 and the concept tube 200 are combined to form a joint unit. The front portion of the nozzle and conceptual tube assembly removes excess molten zinc from the elongated object and adjusts the desired coating thickness on the object by adjusting the slit opening of the nozzle. This excess or excess zinc can be collected and reused in the illustrated molten zinc bath. After wiping the long object via a GAN pressurized flow through the crack opening of the nozzle 100, the coated object is passed through the concept tube 200, where the molten zinc coating immediately solidifies, on the line/rod surface Leave a uniform and round coating. The LIN/GAN combined atmosphere in the concept tube 200 also maintains the coating without oxide, giving the elongated object a bright finish. The temperature of the concept officer is adjusted by the PLc 460. The electromagnetic/proportional valve 470 on the LIN conduit is switched to maintain the temperature unchanged in response to changes in temperature input and temperature measurements of the thermoelectric 260 in the concept tube 200. The inner chamber pressure of the concept tube is maintained at a low pressure by using a porous inner independent tube. This also provides a uniform pressure distribution in the interior of the concept tube. In addition, the process can be arbitrarily monitored by one or more attached thermocouples located at a plurality of different points throughout the process. In the particular embodiment illustrated in Figure 5, the thermocouple 260 monitors temperature as the object passes through the system. You can also use any temperature sensor 520 and electromagnetic thickness sensor 51 to adjust the process. In addition,
