Description of the Invention: [^ 明明家名名页3 TECHNICAL FIELD The present invention relates to a molten glass conveying apparatus component applicable to a glass manufacturing apparatus such as a vacuum degassing apparatus, and a component of the molten glass conveying apparatus. Glass manufacturing equipment. [Prior Art J BACKGROUND OF THE INVENTION In a glass manufacturing apparatus such as a vacuum degassing apparatus, a constituent material of a guide glass of molten glass is required to have heat resistance and excellent corrosion resistance to molten glass. As a material that satisfies this requirement, Ming or Ming alloy is currently used (refer to Patent Document 1). Insulating bricks are disposed around the conduit of the molten glass made of platinum or platinum alloy so as to surround the conduit. Since the platinum or platinum alloy constituting the conduit has a different thermal expansion coefficient from the thermal barrier system disposed around the conduit, the difference in the amount of thermal expansion during heating and the difference in the amount of shrinkage during cooling become a problem. In order to absorb the difference in the amount of thermal expansion during heating or the difference in the amount of shrinkage during cooling, a cement-like amorphous ceramic material is filled between the two, so that when temperature changes occur, The person can move relatively slightly. In the prior art, the inventors of the present invention have found that depending on the arrangement of the conduit of the molten glass, When the amorphous ceramic material is filled by light, there is a case where the difference in the amount of thermal expansion during heating or the difference in the amount of shrinkage during cooling may not be completely absorbed. Fig. 1 is a cross-sectional view showing a configuration example of a vacuum degassing apparatus. In the vacuum degassing apparatus 100 shown in Fig. 1, the vacuum degassing tank 130 is housed in the decompression housing 120 so that the long axis thereof is aligned in the horizontal direction. A riser pipe 140 is attached to the lower side of the vacuum degassing tank 130, and a down pipe 150 is attached to the lower side of the other end. In the decompression housing 120, a heat insulating material 160 is disposed around the vacuum degassing tank 130, the riser tube 140, and the down tube 150. The riser pipe 140 is connected to a structure (not shown, for example, a glass dissolution tank) on the upstream side of the molten glass via the conduits 170, 180, and 190. The downcomer 150 is connected to the downstream side structure (not shown, for example, a float bath glass forming apparatus) via the ducts 200, 220, and 240. More specifically, the riser 140 having the central axis in the vertical direction is via a duct 170 having a central axis in the horizontal direction, a duct 180 having a central axis in the vertical direction, and a duct 19 having a central axis in the horizontal direction. It is connected to the structure on the upstream side. On the other hand, the down tube 150 having the central axis in the vertical direction is via a catheter 2 having a central axis in the horizontal direction, a catheter 220 having a central axis in the vertical direction, and a catheter having a central axis in the horizontal direction. 240 is connected to the structure on the downstream side. Further, the riser pipe 140, the down pipe 150, the pipes 17A, 180, 190, 200, 220 and 240 are pipes made of platinum or platinum alloy. 201029941 Although not shown, the insulating brick is disposed so as to surround the above-mentioned platinum or platinum alloy tube, and the platinum or platinum alloy tube and the heat insulating monument are filled with an amorphous ceramic material. In such a structure, only the tubes (140, 150, 180, and 220) having the central axis in the vertical direction alone or only the tubes (170, 190, 200, and 240) having the central axis in the horizontal direction are separately provided. The difference between the amount of thermal expansion of the turned or turned alloy tube and the insulating brick during heating or the amount of shrinkage during cooling can be absorbed by the amorphous ceramic material filled between the two. However, the joint portion of the tube having the central axis in the vertical direction and the tube having the central axis in the horizontal direction (the joint portion of the riser tube 140 and the duct 170, the joint portion of the down tube 150 and the duct 200, the duct 170 and the duct) In the joint portion of 180, the joint portion between the duct 18A and the duct 190, the joint portion between the duct 200 and the duct 220, and the joint portion between the duct 220 and the duct 240, there is a difference in the amount of thermal expansion during heating or contraction during cooling. The difference in the amount cannot be absorbed by the amorphous ceramic material and cracks occur at the joint portion. When the turtle φ is cracked at the joint portion, there is a problem that the molten glass leaked by the crack erodes the heat insulating brick disposed around it. As a result, there are problems such as reduced productivity due to repair work and shortened equipment life. In order to solve the problems of the above-described conventional techniques, the present invention has an object of providing a molten glass conveying apparatus element and a glass manufacturing apparatus including the molten glass conveying apparatus element, wherein the molten glass conveying apparatus element has a ceramic structure, which prevents the cause The joint between the duct having the central axis in the vertical direction and the duct having the central shaft in the horizontal direction is cracked due to contraction during thermal expansion or cooling upon heating, and even if there is molten glass due to some original 5 201029941 The situation is also difficult to be eroded. Provided is a means for solving the problem. The present invention provides a component for the above-mentioned purpose, comprising: a duct structure for molten glass, wherein at least one first conduit is drawn, and the fifth guide is used. The first conduit has a central axis in a vertical direction, and the second conduit is connected to the first guide and has a scarf core in a horizontal direction, and the first conduit and the second conduit are surface-turned or alloyed. And the ceramic structure is disposed in the periphery of the j-th conduit and the first portion, wherein the ceramic structure contains 75 wt% or more of cerium oxide based on the mass% of the entire composition, and the foregoing In the zirconia, the proportion of the cubic zirconia accounts for 80% by weight or more; the average open porosity of the ceramic structure is 5 to 60%; and the ceramic structure is 20 to 100 (the linear expansion coefficient of the TC is 8 χ 10-6) Further, the present invention provides a glass manufacturing apparatus comprising the molten glass conveying apparatus element of the present invention. Advantageous Effects of Invention In the molten glass conveying apparatus component of the present invention, platinum or I is white The molten glass conduit is approximately the same as the linear expansion coefficient of the ceramic structure disposed around the conduit, so that the difference in the amount of thermal expansion during heating or the amount of shrinkage in the cold portion is extremely small. Therefore, it is possible to prevent the central axis from being vertically. 201029941 • The joint between the duct and the duct having the central axis in the horizontal direction is cracked due to thermal expansion during cooling or contraction during cooling. Moreover, even if the molten glass leaks for some reason, In the prior art, it is difficult to be eroded by the ceramic structure. Further, in the prior art, cracking of the ceramic structure due to cracking at the joint portion of the conduit due to shrinkage during thermal expansion or cooling during heating and prevention of leakage of molten glass are prevented. However, it is difficult to achieve both of them. However, the slope glass containing the element of the molten glass conveying apparatus of the present invention is prevented from being cracked at the joint portion of the camp due to thermal expansion during heating or shrinkage during cooling. And even if the molten glass leaks due to some original Hungarian, the ceramic structure is hard to be eroded, and thus has excellent reliability, V length And the glass is made in a stable manner.

For example, it can be one horizontal pipe connected to one vertical pipe. Furthermore, it is also possible that one horizontal pipe is connected to one end side with respect to one vertical pipe, and the other end side of the horizontal pipe is more connected with another vertical pipe (corresponding to FIG. 1) The structure of the combination of the conduits 150, 200, and 220, etc.); or, the structure is more connected to more than one vertical tube or horizontal tube or both (corresponding to the conduits 150, 200 in FIG. 1 , The structure of the combination of 220 and 240, etc.).

The same is true for horizontal pipes. It is not strictly required that the central axis is just in the horizontal direction, and the central axis may be inclined to some extent with respect to the horizontal direction. In other words, the vertical pipe and the horizontal pipe system in the present invention are intended to indicate their relative relationship. When the pipe is a vertical pipe, the pipe which is related to the transaction is a horizontal pipe. 201029941 Further, if the installation workability of the ceramic structure is considered, the angle between the vertical pipe and the horizontal pipe should be 90 ± 1 在 in the joint portion between the vertical pipe and the horizontal pipe. In the range. In the present invention, since the first duct and the second duct are used as a duct for melting glass, the constituent material is required to have heat resistance and excellent corrosion resistance to molten glass.

In other words, in the present invention, cubic yttrium oxide (which is a completely stabilized cerium oxide) is used as a heat insulating monument disposed around the first conduit and the second conduit. By using cubic cerium oxide as a main component, the amount of thermal expansion during heating or the amount of shrinkage during cooling in the first and second conduits and the ceramic structure disposed around the first conduit and the second conduit become approximately equal. As a result, the difference in the amount of thermal expansion during heating or the amount of shrinkage during cooling becomes extremely small, and it is possible to prevent the joint portion between the vertical pipe and the horizontal pipe from being cracked due to thermal expansion during heating or shrinkage during cooling. As shown below, the cubic cerium oxide which is completely stabilized cerium oxide has a linear expansion coefficient close to that of the platinum or platinum alloy constituting the catheter at 20 to 10 〇〇c, so that it can be prevented from occurring at the joint portion.

Among the enthalpy errors contained in the ceramic structure, the proportion of cubic oxidization error should preferably be more than 85 wt%, and more preferably 9 〇 _ or more. The shrine structure 2 of the invention f contains an (4), and the stabilizer is added to make the emulsified junction a cubic oxidization error (stabilized oxidative error) as a residual portion other than the oxidized junction. Furthermore, the residual portion may contain unavoidable impurities and the like. Further, as long as the present invention is not impaired, the ceramic structure 2 of the present invention may contain a total of other components than the oxidative error and the stabilizer. As the other components, for example, ruthenium or Mg 添加 added to improve the sinterability may be mentioned, and these components may be contained in an amount of about 5 wt% in total. _ As a money agent, there are oxidized period, oxidized decoration, oxidized town, oxidized about, yttrium oxide, etc., but it is considered to be excellent for the excellent resistance to (N) glass, easy to obtain, and stable for a long time at high temperatures. It should be oxidized and oxidized. When at least one selected from the group consisting of cerium oxide and cerium oxide is used as a stabilizer, the total content of the two is preferably 6% by weight or more, and more preferably 8% by weight or more, and particularly preferably 1% by weight or more. . 11 201029941 However, if the amount of stabilizer added is too large, there will be problems such as difficulty in sintering and increase in raw material costs. For this reason, the total content of both is preferably 25 wt% or less, and more preferably 20 wt% or less. The zirconia content in the ceramic structure differs depending on the amount of the stabilizer added, and is 75 wt% or more, and more preferably 80 wt% or more, more preferably 85 wt% or more, in order to make the coefficient of linear expansion within a predetermined range. On the other hand, since the addition amount of the stabilizer is also taken into consideration, the upper limit of the zirconia content in the ceramic structure is about 94% by weight. The ceramic structure of the present invention has an average open porosity of 5 to 60%. Although the ceramic structure of the present invention has excellent corrosion resistance to molten glass, if the average open porosity exceeds 60%, the corrosion resistance to molten glass is lowered. On the other hand, if the average open porosity is less than 5%, the thermal shock resistance of the ceramic structure will be lowered. Further, since the heat capacity is increased, the first pipe la and the second pipe lb made of the alloy and the ceramic structure 2 are easily inconsistent with each other at the time of thermal expansion at the time of heating or contraction at the time of cooling. There is a fear that cracks may occur in the joint portion between the first pipe 1a of the vertical pipe and the second pipe 1b of the horizontal pipe. In addition, the time required for heating or cooling is also prolonged. The ceramic structure of the present invention preferably has an average open porosity of from 25 to 60%, more preferably from 30 to 50%, particularly preferably from 35 to 45%. However, once the average porosity is increased, a portion of the ceramic structure which is hard to conduct from the heat of the conduit is generated, which hinders thermal expansion of a part of the ceramic structure and causes a part of the conduit to be burdened. Therefore, in the case of not causing the burden on the catheter, or further improving the corrosion resistance, the ceramic 201029941 • the average open porosity of the structure should be 5 to 35%, more preferably 8 to 30%, particularly preferably 10 to 25 %. The average open porosity of the ceramic structure can be determined by a measurement using an Archimedes method or a mercury porosimeter. The ceramic structure of the present invention has a different open porosity depending on the location. For example, by making the position of the portion facing the j-th conduit and the second catheter lower than that of other portions, the durability against molten glass can be improved. In the second shot, a gap 3 is provided between the first duct 1a and the second duct 1b and the pottery structure Φ body 2. > As described above, in the towel of the present invention, the amount of shrinkage during the expansion or cooling is approximately equal to that of the first conduit 1a and the second conduit and the ceramic structure 2 disposed on the circumference of the napkin. . However, since the thermal conductivity of the turned-to-face alloy constituting the first illuminating duct U and the second duct 11 is different from the oxidizing recording constituting the shouting structure 2, depending on heating conditions or cooling conditions, during thermal expansion or cooling during heating At the time of contraction, a 'no-in case' occurs between the two, and there is a fear that cracks may occur in the joint portion between the i-th conduit u of the vertical pipe and the second 'catheter lb of the horizontal pipe. By providing the gap 3 between the first duct U and the second duct 1b and the Tauman structure 2, it is possible to absorb the inconsistency between the time when the two are contracted during expansion or cooling. Further, cracking of the joint portion is prevented. Further, in the present invention, the amount of thermal swell at the time of heating or the amount of contraction during cooling is approximately equal to the first catheter 1a and the second catheter lb and the ceramic structure 2 disposed around it, and thus When the maximum diameter of the first conduit la and the second conduit lb is r (mm), the width d of the gap 3 is preferably 0.5 mm or more '0·02 χ r (mm) or less. When the width d of the gap 3 is less than 55 mm, there is a concern that the time point at which the thermal expansion at the time of heating or the contraction at the time of cooling is not sufficiently absorbed may be inconsistent. On the other hand, when the width d of the gap 3 is larger than 0.02 xr (mm), an excessive gap remains between the two after expansion, and the first duct 1a and the second duct 1b are deformed by the molten glass passing through the inside. problem. Further, the maximum diameter r is preferably 60 mm or more. The reason is that when the maximum diameter r is 60 mm or more, the rigidity of the catheter is difficult to secure, and the effect of the present invention (prevention of occurrence of cracks in the joint portion) is particularly desirable. Further, although the maximum diameter r is different depending on the portion to be used for the catheter, the riser 14〇, the downcomer 15〇, and the conduits 170, 180, and 190 connected thereto are shown in Fig. 1 . In the case of 200, 220 or 240, it is generally 120~400mm. The width d (mm) of the gap 3 is preferably from 1 to 3 mm, particularly preferably from 1.5 to 2.5 mm. Since cubic cerium oxide is a high-priced material, it is preferable from the viewpoint of cost that the ceramic structure disposed around the first conduit and the second conduit is preferably the minimum required. Specifically, it is preferable to arrange the ceramic structure (hereinafter also referred to as "the first ceramic structure"), and then arrange a general heat insulating monument as the second ceramic structure on the outer side. In this case, as the second ceramic structure, a heat insulating brick whose main system is selected from at least one of a group consisting of aluminum, magnesium, lanthanum and cerium may be used. 201029941 As a specific example of the thermal insulation monument of the second ceramic structure, ^ Fossil eve / oxidized inscription heat insulation monument, oxidized error insulation brick and ° 彳 如 如 氧 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Commercially available products include sp_15 (曰之丸...

In the test body used in Comparative Example 1, a gap of 3 was placed around the hollow tube lc to arrange a test example. As a second shattering structure, the commercially available oxidized ash/oxidized heat insulation was used. In place of the ceramic structure 2 disposed around the hollow tube lc, the gap 3 is filled with aluminum stucco which is mixed with water and agitated hollow particles. A temperature cycle test was carried out in the same manner as in Test Example 1 except that the layer of the ceramic material was not formed to have no gaps. After the temperature cycle test, the test piece was unwrapped and the tube k was cut. As a result, the hollow tube was finely broken by the name of the portion to which the flange 5 was attached.
