Description of Mullite Refractory Brick
Mullite refractory bricks are made of synthetic fused mullite or sintered mullite, pressed by selected shaping processes, and fired in high temperature furnaces. Mullite bricks offer high density, low porosity, good hot strength, and good slag resistance. Mullite bricks are preferred for high temperature, high load applications, such as at the hot end of regenerative chambers of glass melters, the superstructure of the furnace, and the arch of glass fiber melters, due to their excellent thermal properties, excellent strength at high temperature, great resistance to thermal shock, etc.
Application of Mullite Refractory Brick
Mullite refractory bricks are mainly used for top of hot blast stove, stack and bottom of the blast furnace, regenerative chamber of glass melter, ceramic post sintering kiln, furnace lining for dead angle of petroleum cracking and etc.
