Fire Clay Bricks

By using advanced technology, the clay insulating refractory bricks is featured with homogeneous structure, high mechanical strength, precise size, low thermal conductivity and long service life. The brick is widely used in the insulating layers and linings of various heat engineering equipments such as hot blast stove, coke oven, heating furnace, boiler, tunnel kiln and so on, which saves over 30% energy. It is one of ideal insulating materials for energy saving. Physical and chemical properties of NG clay insulating refractory bricks.
