Advantages of Alumina Hollow Ball Brick
High-strength wear-resistant plastic refers to a mixture of high-grade refractory materials such as corundum, mullite or silicon carbide, and a binder and an admixture (anti-shrinkage agent, preservative, antifreeze).
The high-strength wear-resistant self-flowing castables are made of high-quality bauxite clinker, mullite and fused corundum. The pure calcium aluminate cement, corundum micro-powder and silicon micro-powder are used as binders.
Corundum mullite high-strength wear-resistant refractory castables have high compressivestrength, good high temperature volume stability and thermal stability, excellent wear resistance and strong corrosion resistance.
Anti-seepage refractory castable has the characteristics of: compressive strength, high flexural strength and strong anti-permeability.
Dry anti-seepage refractories works well with simple construction, good thermal insulation effect and strong anti-permeability. The working principle of Dry anti-seepage refractory material is to react alkali ions in materials and metal liquids at high temperature, form isolation layer on the surface, prevent sodium salt from going to cathode block.
