Silica mullite brick

Silica mullite brick is a Chinese naming convention. It works at transition zone in cement rotary kiln. In small and some medium-sized cement rotary kilns, it can replace magnesite spinel bricks.

Other name: Special high alumina brick, high alumina brick with SiC

Model Number: HCR-I,HCR-1450,HCR-1550,HCR-1650,HCR-1680,SiC wear-resisting brick

Certification: ISO 9001-14001

Minimum Order Quantity: 5 MT

Silica Mullite Brick

Description:

Silica mullite bricks are silicon carbide-mullite products, with silicon carbide and high alumina bauxite clinker as the main raw materials. Since silicon carbide is oxidized to produce silicon dioxide, it reacts with aluminum oxide to form mullite, which can increase the density and strength of the product, and form a protective film on the surface of the product to prevent further oxidation of silicon carbide. Maintaining a certain content of silicon carbide in the silicon-molybdenum brick can improve the thermal shock stability, wear resistance and erosion resistance of the product.

Advantage:

Dense structure, high wear resistance, high refractoriness under load, low thermal conductivity

Application:

Cement rotary kiln
