Fireclay bricks belong to one of the main varieties of aluminum silicate products. It is a refractory product made of clay clinker as aggregate and refractory soft clay as binder with Al2O3 content in 30%~45%. Fireclay products have good thermal shock resistance and certain resistance to acid slag erosion. Fireclay bricks are widely used in blast furnace, hot-blast stove, glass kiln, soaking pit, annealing furnaces, boiler, cast steel systems and other thermal equipment. It is one of the refractory products with large consumption.
