The invention belongs to the field of
refractory bricks, and in particular relates to
refractory bricks for a
rotary kiln. Each
refractory brick comprises a
glass fiber heat
insulation layer, fixing limiting rings, a
kiln cavity, a rock
wool upper cover, a rock
wool lower cover, embedding grooves, embedding limiting blocks, refractory clamping bricks, a filling groove cavity,
glass fiber filling blocks, embedding clamping grooves, a first refractory
slurry layer, mounting holes, a second refractory
slurry layer and mounting strips. According to the refractory bricks, the structure is reasonable; after being used, the refractory bricks perform fire resisting through the self-refractory property, and meanwhile, through the cooperation of the
glass fiber filling blocks, the rock
wool round covers and the glass
fiber heat
insulation layer, heat insulating can be effectively carried out, so that the integral heat insulation effect of the
rotary kiln is improved, and the heat loss is reduced; when the refractory clamping bricks are laid to form the
kiln cavity, the refractory clamping bricks and the embedding clamping grooves are clamped, so that suspending is carried out, and limiting is realized; and mounting and stacking are simple, and when laying is carried out, the refractory clamping bricks are not needed to be manually supported, so that the convenience is provided for construction.
