Description for Acid Resistant Refractory Bricks
Silica Brick
Silica Brick is a kind of acid refractory with over 93% SiO2 content and 2.35g/cm3 true density, which is fired under high temperature condition. Silica Brick adopts silica as the raw material and lime milk, iron-phosphorus and sulfite lye as the binding agent and mineralizer, which is widely used in coke oven, glass furnace, hot blast stove, silica brick down-draft kiln and tunnel kiln, nonferrous metallurgy and acid steel furnace with properties of strong resistance to acid slag erosion, low volume expansion and better high temperature stability and etc.
Fireclay Brick
Fireclay brick is clay refractory product of aluminium silicate materials with 30%~40% content of Al2O3, which is made of 50% plastic clay and 50% hard clay chamotte according to certain grading requirement to be mixed and fired at the high temperature of 1300~1400℃ after molding and drying. Fireclay brick is faintly acid refractory product that can resist erosion from acid slag and acid gas. Fire clay refractory brick has good thermal properties and can resist thermal shock. Fireclay brick is used in cement rotary kiln, steel-smelting furnace, iron-fining furnace and foundry furnace.
Features of Acid Resistant Refractory Bricks
