Product description
Ceramic firebrick have good wear resistance: clay firebrick has high hardness and density, and its surface is not easy to wear, so it can maintain surface finish and mechanical strength at high temperatures for a long time.
Ceramic firebrick have strong corrosion resistance: clay and kaolin in clay refractory brick materials contain high silicate and aluminate, which can resist various acids, alkali, salt and other chemical corrosion, so it is widely used in chemical industry, metallurgy, electric power and other fields.
Applications of ceramic firebrick
Power industry: ceramic firebrick can be used in power station boiler, flue, desulfurization equipment, dust removal equipment, burner and other high temperature parts.
Other industries: ceramic firebrick can also be used in glass, ceramics, petrochemical, mining, machinery manufacturing and other fields.
