The acid-resistant refractory bricks produced by our company adopt high-grade refractory aggregates, powders, additives, etc. After reasonable grading and high-temperature firing, they can fully meet the acid and high temperature resistance of furnace lining refractories under various acid regeneration process conditions.
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.
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.
