Production process of silica mullite bricks

The production process of silica mullite bricks mainly includes the selection of raw materials, mixing, molding, drying, firing and so on. First, the high-purity silicate raw materials are crushed, and then a certain amount of additives and binding agents are added to form a slurry after mixing. Next, the slurry is pressed into a billet, and then processed by drying and firing to finally obtain silica mullite bricks.

Advantages of silica mullite bricks

The advantages of silica mullite bricks are characterized by its good high temperature resistance, strong corrosion resistance and low coefficient of thermal expansion. In the high temperature environment, silica mullite brick can maintain stable physical and chemical properties, not easy to be oxidized, corrosion and other effects. In addition, the low coefficient of thermal expansion of silica mullite bricks can effectively reduce the stress and deformation caused by temperature changes.

Applications of silica mullite bricks

Silica mullite bricks have a wide range of applications and are mainly used for kiln linings, pipelines, valves and other parts in the iron and steel, cement, glass, ceramics and other industries. In the iron and steel industry, silica mullite bricks can be used for heating furnace, steelmaking furnace and other equipment lining; in the cement industry, silica mullite bricks can be used for rotary kiln, decomposition furnace and other equipment lining; in the glass industry, silica mullite bricks can be used for glass melting kiln, annealing furnace and other equipment lining; in the ceramics industry, silica mullite bricks can be used for tunnel kiln, shuttle kiln and other equipment lining.
