Introduction
Our monolithic refractories for blast furnace and hot blast stove systems are formulated using premium raw materials such as dense corundum, brown fused alumina, and silicon carbide, combined with micro-powder bonding technology. These materials exhibit excellent workability, outstanding thermal shock stability, and strong resistance to molten iron and slag erosion. Available in castable, gunnable, and pumpable forms, they enable flexible construction and rapid hot repairs, significantly reducing downtime and extending service life of critical high-temperature equipment.
Key Advantages
01
Superior Thermal Shock & Erosion Resistance
Engineered with advanced additives and micro powder bonding, these refractories withstand frequent temperature fluctuations and resist corrosion from molten iron and slag, ensuring durable performance in the most demanding zones.
02
Flexible Installation & Fast Repair
Supporting casting, gunning, and pumping methods, these materials allow for rapid on-site construction and hot patching without extended shutdowns, greatly improving equipment utilization and reducing maintenance costs.
03
Strong Adhesion & Dense Lining
Formulated for excellent bonding to existing linings and炉壳, these materials form a continuous, joint-free monolithic structure that prevents slag penetration and enhances overall furnace integrity and safety.
