Fireclay Brick
Fireclay bricks belong to the main varieties of silica-aluminum products, which are refractory products made of clay clinker as aggregate and fireclay as binder with Al2O3 content of 30-48%. Mainly used in thermal boiler, glass kiln, cement kiln, fertilizer gasifier, blast furnace, hot blast furnace, coke furnace, electric furnace, cast steel furnace.
