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.
The Unburned slide gate plates series products are made of corundum, mullite, and high-quality clinker clinker. Unburned slide gate plates are made by adding flake graphite, silicon carbide, and silicon metal powder, which are made by high-pressure molding, low-temperature heat treatment and grinding.
Checker Brick is a kind of heat-transfer medium, which is mainly used for middle-upper part of regenerative chamber in hot blast stove for thermal storage in the burning period.
