Applications:
 

Compared with ordinary clay bricks, kiln furnace SK34 SK36 SK38 Refractory Fire Brick with Al2O3 content of 30%~48% made of refractory clay as the main raw material. Using refractory clay, floating beads, and refractory clay clinker as raw materials, adding binders and sawdust, after batching, mixing, molding, drying and firing, products with a bulk density of 0.3~1.5g/cm3 can be obtained. It accounts for more than half of the total output of heat-insulating refractory bricks, with tiny pores evenly distributed inside, with a high porosity. Therefore, it can be ensured that the furnace wall loses less heat, and the fuel cost will be reduced accordingly. Lightweight clay bricks also mean less heat storage, so heating and cooling are faster, allowing faster periodic operations. Lightweight clay refractory bricks are suitable for the temperature range of 900℃~1650℃.
