[0001] The utility model relates to the technical field of kilns, in particular to a fault-tolerant kiln wall capable of preventing thermal expansion and contraction. Background Art

[0002] At present, the wall bricks used in kilns are all ordinary refractory bricks with rectangular structures. In order to achieve a better fireproof effect, two or three layers of refractory bricks with staggered masonry joints are usually laid. The refractory bricks are bonded with high-temperature adhesives. When laying wall bricks, if the masonry joints of each layer of refractory bricks are not completely staggered, fire penetration problems will occur, affecting the use of the kiln. Therefore, the masonry accuracy requirements of the wall bricks used in kilns are relatively high.

[0003] The kiln walls of existing kilns are all ordinary refractory bricks with a rectangular structure. The high-temperature adhesive between the refractory bricks will fall off during the thermal expansion and contraction process of the kiln temperature, causing dirt on the product and forming waste, seriously affecting the improvement of product quality and the improvement of economic benefits.

[0004] To this end, a fault-tolerant kiln wall with thermal expansion and contraction resistance is proposed, which has the advantages of preventing thermal expansion and contraction of the kiln wall and improving the fault tolerance of the product, thereby solving the problems in the above-mentioned background technology.
