High-strength mullite castables are refractory castables mainly made of mullite as the principal crystalline phase.

Coating resistant castable is made of high-aluminum silicon carbide.

High-strength and High-aluminium Refractory Castables are refractory castables made of high-aluminum as aggregates and powders and added with binders.

Steel Fibre Reinforced Refractory Castable is made of high-grade bauxite clinker as aggregate, high-quality bauxite clinker and fine corundum powder as matrix, superfine powder and other composite materials.

Guimo red bricks are mainly made of high-grade high-alumina bauxite, large crystalline silicon carbide, andalusite, fused white corundum, etc., adding high-quality binders and additives.

The main function of the inner cylinder of all-ceramic preheater is the strength of the hydrogenation cyclone, which enhances the heat exchange rate between the wind and the material.
