Kiln refractory clay brick is made from clinker clay by mixing, forming, drying, sintering and machine pressing moulding with good resistance to corrosion and abrasion, good thermal shock resistance, good spelling resistance, high mechanical strength, good volume stability under high temperature.
The tap hole clay is used to block the taphole plays an irreplaceable role in ensuring stable and high production of the blast furnace, improving the working strength and environment before the furnace, and prolonging the service life of the blast furnace.
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.
