Product description
Fire kiln bricks 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 fire kiln bricks
Power industry: Fire kiln bricks can be used in power station boiler, flue, desulfurization equipment, dust removal equipment, burner and other high temperature parts.
Construction industry: Fire kiln bricks can be used for building firewalls, fire doors, flue and other parts.
Other industries: Fire kiln bricks can also be used in glass, ceramics, petrochemical, mining, machinery manufacturing and other fields.
