Description

of the feeder, simplifying the design and reducing the weight of the feeder by bending them in the middle of the feeder. at an angle of 75 - 902. This is the construction of the filling slot

The problem is solved by the fact that in the fissure fi- allows to install a spinneret feeder to a poleless feeder for production continuously into the basalt melt, provides minimal fibers from basalt rock melts, which resists the passage of the basalt melt flow - consists of a device for pouring the melt , and minimal heat loss during the supply of melt in the body, filter grid, current leads, spinneret feeder. of the die plate and the die, according to the invention, the filter mesh (4) provides filtration of the pus consists of the upper and lower bodies, basalt melt, heating of the lower layers of the melt, the device for pouring the melt is the organization of the melt flow from the edges of the feeder, a slotted hole placed along from the center of the cover to the center of the die plate (5), stabilization of the upper case, between the cases the melt temperature is set in a given temperature interval - the filter mesh, which is the bottom of the upper case peratures along the entire plane above the die plate - and has holes along the edges, along the perimeter of union with her housings, there is a flange with zigzag-shaped current leads (7) are made horizontally and are cutouts for fastening the feeder, and current extensions of the spinner plate (5). For necessity, the circuits are made horizontally and are extensions of the current distribution through the upper and lower spinner plate and have vertical ribs, the bodies (1, 3) and ensuring uniform heating are attached to the upper and lower bodies from their elements of the spinneret feeder perpendicular to the ends. but between the current leads (7) and the fillet housings

At the same time, the spinnerets have an inner diameter of a single feeder, vertical ribs are installed 1.0-4.0mm, and the ratio of the areas of the spinneret holes (8) is triangular. The horizontal placement of the filter mesh and the filling slot current leads allows to simplify the design of the hole is 1:(1.1-1.2):(1.2-1.4). feeder feeder and also provides an opportunity

The design of the device for pouring the melt, placing it directly in the base melt in the form of a slit in the body of the upper body, allows air. install the feeder directly into the melt. The flange (6) is intended for fastening the fil-basalt, to minimize the supply path of the feeder feeder to the water-cooling cooler - the coolant to the feeder, to reduce the resistance of its cooler. The mounting flange (b) has transverse zigzags and heat losses, to reduce the weight of the spinneret, go-shaped cutouts to reduce heat losses and feeder costs. of electricity during feeder operation. According to this

The filter mesh with holes along the edges of the flange reduces the passage of electric current and simultaneously functions as a filter and a current distributor. The flange has a smaller area for heat dissipation, which ensures homogenization of the melt water. The ratio of the areas of the material of the flange and the composition and temperature, as well as the simplified design of the cutouts can be 1: (1 - 2.5). In this way, it reduces the mass of the feeder feeder. such a flange (6) allows you to reduce the cost of electricity

The execution of the zigzag mounting flange of the three energy and heat loss through the flange (6) reduces the heat loss from the feeder and the melt during the operation of the feeder feeder. basalt It was experimentally established that the

The horizontal placement of current conductors, which the diameter of the spinneret (9) for the production of continuous, are extensions of the spinneret plate, made of vertical basalt fibers with diameters of 6-18μm, with their ribs, contributes to the distribution of current between should be d-1.5-3.2mm, and the length I-(1,4-2,1)a. upper and lower housings, a filter screen, a determining diameter and length of the feeder feeder and a feeder plate, which contributes to uniform viscosity of the melt, the force of surface heating of these elements and the basalt melt by tension, and the angle of wetting of the basalt melt. to the entire volume of the feeder. All this helps to increase the productivity of the feeder, simplify the resistance to the passage of the melt, reduce its structure and weight. performance of the feeder, but it is possible to obtain

Fig. 1, 2 shows the design of slotted cotton wool with small diameters of 5-9 microns. At the feeder feeder. A slotted spinneret with vein diameters of the holes creates a large spinner consists of: the upper body (1), resistance to the passage of the melt, the productivity of the feeding slot (2), the lower body (3), the filter increases, but the melt can flow on the bottom grid (4), spinner plate (5), the flange of the spinner plate and the production of fibers attachment (6) fastening, current leads (7) with vertical kicks. The length of the die affects the ribs (8) and the die (9). cooling and viscosity of the melt in the process of drawing

Design elements of a fissured spiny neoplasm. The diameter and length of the feeder determines the following functions. depending on the chemical composition of the basalt,

The upper case (1) provides additional technological modes of production of fibers and heating of the basalt melt along the perimeter of the feed- the required diameters of the fibers. For a productive ka, it constructively forms a filling gap (2) and the production of continuous fibers from melts gives the level of the melt above the spinneret plate (5). basalts, the optimal ratio of hole areas

The filling slot (2) is made in the body of the upper core of the die (9), the filter mesh (4) and the filling tube (1) in the center of the lid in the form of an elongated slot (2) should be 1:(1.1-1.2 ):11.2-1.4). cracks It has been experimentally established that the most optimal for the production of the spinneret feeder is the execution of the edges of the gap of torn basalt fibers are made of pla-

tin-rhodium alloys. Improving the design of the basalt feeder reduces its weight and significantly affects the fibers. On the die plate (5) through the dies, its value. (9) transformation of the basalt melt occurs

The slotted spinneret feeder works on continuous fibers. On fiber-input processes. the diameters and length of the spinnerets affect the cutting.

The basalt melt directly from the feeder flows through the filling slot (2) into the cavity of the upper body (1) and onto the filter mesh to ensure a stable and productive flow (4). In the upper part of the feeder, the temperature of the basalt lavas is stabilized by viscosity, basalt melting temperatures in the interval of setting, the temperature interval of their production of temperatures over the entire volume of the upper corpulokons. Yes, the temperature interval of production of su. This is ensured by heating the walls of the upper continuous basalt fibers in the spinner body and the filter mesh (4) at the feeder can be 1220-1290"C, and the difference in the electric current passed through them. Further, the temperature of the spinneret field of the spinneret plate, the basalt melt passes through the holes of the filter should not exceed -107 C. of the mining grid (4). In this case, the filtration and homogenization of the basalt melt, which is necessary to ensure the stability and production of continuous basalt production, takes place. fibers. This is due to the fact that basalt is a natural raw material in which - to obtain the melt directly from the feeder, there are often inclusions of other refractory mine-furnaces; rales: quartz, mica, andesites, porphyrites and others - to organize stable flow of basic melt. Individual inclusions of refractory minerals, or iron through the feeder; parts of unmelted crystalline basalt - keep the given melt level above the fillet - settle on the filter grid (4). When working with an open field; feeder, thanks to the processes of eutectics and intensification - carry out filtration and homogenization by spreading heating of the filter mesh itself, in the vu zone; holes, these particles gradually dissolve and - to maintain the given temperature of the melt, are washed with basalt melt, which contributes to the stability of the entire volume of the feeder; capacity and productivity of continuous production - to ensure the required melt viscosity of certain fibers. Next, the melt through the holes during production and in the process of producing fibers; of the filter mesh (4) goes to the lower - to maintain the specified temperature interbody (3) and to the spinneret plate (5). For the production of fibers along the entire field of filenometry of the temperature of the basalt melt along the crural plate. pits and in the center of the spinneret plate, holes in the filter- This allows to ensure the stability of the production grid (4) are made on its edges. Therefore, casting of continuous fibers, increase the feeder's permeability to the feeder plate, improve the structure and start from its edges, where the heat losses are greatest, and reduce the weight of the feeder. only then to the central zone of the plate, where the example. yield of melt is less intense. Thanks to the Slotted spinneret feeder for 300 spinnerets. such a design of the filter mesh in the process The spinneret feeder is made of platinum- fiber production melting temperature of the rhodium alloy: 9095 - platinum, 1095 - rhodium. is absorbed and stabilized along the entire plane of the die. The productivity of the die feeder is 15 plates (5). In the process of filtering and flowing - 25 kilograms of continuous basalt drawing of the melt from the edges to the center of the spinneret per hour. of the feeder, its additional mixing and homogenization takes place, which also helps to increase
