Enhancing Performance in Various Industries

Steel Industry Applications

In steel mills, LC 70 castable is used for lining ladles, tundishes, and reheating furnaces. Its high alumina content resists slag attack and metal penetration, reducing downtime for repairs. The material’s abrasion resistance ensures long service life in areas exposed to moving charge and molten metal.

Cement Industry Applications

Cement rotary kilns operate at extremely high temperatures and face continuous chemical attack. LC 70 castable delivers stability and reliability in kiln hoods, cooler zones, and burner outlets. CH REFRACTORIES customizes LC 70 castable for cement kilns to provide superior thermal insulation and chemical resistance.

Glass and Petrochemical Industry Applications

Glass furnaces demand refractories that withstand repeated heating and cooling cycles. LC 70 castable’s thermal shock resistance prevents cracking and spalling, ensuring consistent operation. In the petrochemical sector, LC 70 castable is used for gasifiers and reformer linings, where its low porosity and high strength reduce maintenance costs.
