Description

Technical Field

[0001] The invention belongs to the field of refractory materials, and in particular relates to a refractory brick structure with a stable structure. Background Art

[0002] Refractory materials are one of the key lining materials necessary for the high-temperature kiln industry. In different application environments, they play the roles of high temperature resistance, corrosion resistance, scouring resistance, thermal insulation, and stable structure. In actual use, according to different use environments, refractory materials need to be prepared into products of different shapes. Common structural types include straight bricks, fan-shaped bricks, axe-shaped bricks, knife-shaped bricks, etc., which are directly stacked or built with refractory mud, and the constraints of the external metal furnace shell are used to form a cylindrical body or wall with a stable structure. When the above-mentioned brick types are combined, the adjacent surfaces are simple straight surfaces or curved surfaces, which are easy to form gas or heat transmission channels, which is not conducive to thermal insulation. In particular, the kiln walls, kiln cars, trailers and other parts of some special high-temperature kilns have extremely high requirements on the volatile matter and use temperature of refractory materials. Neither the use of refractory mud bonding is allowed, nor can the metal furnace shell be used for effective constraints, resulting in a significant reduction in the overall structural stability of the refractory products. A new refractory brick structure is urgently needed to solve this problem. Summary of the invention
