Fire bricks is the refractory products produced with clay clinker as aggregate and refractory clay as the bonding agent, with Al2O3 content between 30 ~ 48%. Fire bricks is the oldest; the most widely used refractory material.
Fire bricks is the refractory products produced with clay clinker as aggregate and refractory clay as the bonding agent, with Al2O3 content between 30 ~ 48%. Fire bricks is the oldest; the most widely used refractory material.
Widely used in metallurgy, building materials, chemicals, petroleum, machinery manufacturing, silicate, power and other industrial fields.
Clay refractories material is abundance in raw material, simple in processing and in low price. Therefore, they are more widely used than any other refractory materials. They are used in blast furnaces, hot blast stoves, iron furnaces, ladle and ladle systems and soaking ovens and heating furnaces, Non-ferrous metal smelting furnace, silicate industry and chemical industry kiln and all thermal equipment chimney and flue.
