Description

Technical Field

[0001] The utility model relates to the field of moulds, in particular to a skeleton support tool brick mould for welding and repairing a coke oven wall. Background Art

[0002] The coal in the coke oven carbonization chamber is heated to coke in an air-tight condition. After a long period of use, the refractory wall of the coke oven carbonization chamber is corroded by coal ash, slag, moisture and acidic gas and the effects of hot and cold expansion, which may cause small diameter expansion deformation damage holes, local large expansion deformation damage holes (damage holes) or large expansion deformation damage areas. After the coke is formed in the coke oven carbonization chamber, it needs to be pushed out by the coke pushing equipment. Therefore, the surface of the refractory wall of the coke oven carbonization chamber is required to have good flatness to ensure that the coke can be pushed out of the carbonization chamber smoothly.

[0003] In the prior art, during the repair process of the refractory wall of the carbonization chamber of the coke oven, for smaller expansion and deformation damaged holes, the ceramic welding material is directly melted by a thermal spray device, and then a welding spray gun is used to directly weld and repair the smaller expansion and deformation damaged holes. For large-area expansion and deformation damaged areas, it is necessary to dismantle the refractory wall and rebuild the refractory wall with prefabricated zero-expansion silica bricks. At present, for locally larger expansion and deformation damaged holes, if a welding spray gun is used to directly spray and repair the ceramic welding material, the edge of the expansion and deformation damaged hole can be supported by the edge of the expansion and deformation damaged hole, but it is located in the center of the expansion and deformation damaged hole, and there is no skeleton support. It is difficult to achieve welding and repair of locally larger expansion and deformation damaged holes by spraying ceramic welding material alone. Based on the above-mentioned defects in the prior art, the inventor has developed a skeleton support tool brick for welding and repairing coke oven walls, which can well solve the above-mentioned problems in the prior art. However, this kind of tool brick is traditionally formed into brick blanks using wooden molds. The brick blanks formed by wooden molds obviously do not meet the density standards and are also lacking in strength. Therefore, a machine-pressed steel mold is urgently needed.
