Product Description

Product Description

Low Cement Refractory Castable is a high-performance monolithic refractory material specially developed for steelmaking ladles and converters operating under high temperature, thermal shock, and mechanical stress.

Compared with ordinary refractory castables, this product features low cement content, resulting in higher strength, better thermal stability, and improved resistance to molten steel and slag corrosion.
It is widely used in ladle working lining, ladle safety lining, and converter lining systems in steel plants.

Features

Low Cement Content
Reduced CaO content improves refractoriness, slag resistance, and thermal stability.

High Mechanical Strength
High cold crushing strength ensures excellent resistance to erosion and abrasion during steel tapping and refining.

Excellent Thermal Shock Resistance
Stable performance under frequent heating and cooling cycles in ladle and converter operations.

Good Workability
Suitable for casting and vibration installation, ensuring dense and uniform lining.

Long Service Life
Helps extend lining service life and reduce furnace maintenance frequency.

Applications

Steel ladle working lining
Steel ladle safety lining
Converter lining
Steelmaking furnace monolithic lining systems
