Refractory bricks for the cement industry

There are many kinds of refractory bricks used in the cement industry: Direct-Bonded Magnesite chrome Bricks, Magnesite chrome bricks, Magnesia spinel bricks, Anti-strip alumina bricks, Silicon mullite bricks, Series alkali proof brick.

Direct-bond magnesite chrome bricks

Direct-bond magnesite chrome brick is a product made from fused magnesite and chrome concentrate sintered from high purity or secondary purity. It is sintered under high temperature and ultra temperature with fewer foreign materials, where the glass phase is centered in the triangular space, and the crystalline phase bonds directly with the crystalline phase. Featured by low porosity, high compressive strength, strong wear resistance, good erosion resistance, and thermal shock resistance capacities as well as anti-strip properties, it applies to the calcining zone of dry-process cement rotary kiln.

Anti-striping alumina brick and silicon mullite brick

The anti-striping alumina brick produced by our company is produced with special bauxite chamotte by adding aragonite or ZrO2 and molding under high pressure according to a certain proportion. Featured by strong anti-strip capacity, calcium, sodium, sulfur dioxide, chlorine and basic salt resistance, and low thermal conductivity, it is an ideal material for the transition zone and decomposing zone of cement kiln.

The silicon mullite brick produced by our company is produced with special bauxite chamotte by molding under high pressure and sintering under high temperatures. Featured by high ambient compressive strength and high structural strength. With good thermal shock resistance and wear resistance as well as strong anti-strip, it is an ideal material for the transition zone and decomposing zone of cement kin. cement kiln.
