Introduction
This alumina-silicon carbide castable series is engineered for hot metal ladle lips and torpedo car mouths where severe iron and slag erosion occurs. Manufactured from high-alumina aggregates, silicon carbide and special additives, the material is designed for monolithic casting without shrinkage at service temperatures, delivering high strength and good volume stability. It minimizes slag adhesion on ladle lips, and any adhered slag is easily removable. Available in three grades—JX-SK60 for ladle lips, JX-TBD65 for ladle bottom repair, and JX-YLK70 for torpedo car lining and mouth repair.
Key Advantages
01
Strong Slag & Iron Resistance
Resists chemical attack and mechanical erosion from molten iron and slag with low penetration, significantly extending service life of ladle lips and torpedo car mouths.
02
Good Thermal Shock Stability
Withstands rapid temperature fluctuations during hot metal charging and tapping, preventing cracking and spalling under cyclic thermal stress.
03
No Shrinkage & Easy Cleaning
Maintains dimensional stability at service temperatures with minimal slag adhesion; any adhered slag is easily removable, reducing maintenance downtime.
