Castable Refractory
Castable Refractory for flow control and ladle applications is a precision-engineered, vibration-cast monolithic material formulated specifically for the structural and thermal demands of steel ladle bottoms, tundish linings, and surrounding flow control assembly housings. Unlike general-purpose castables, these grades are optimized for direct contact with molten steel and aggressive ladle slags, combining high density, low porosity, and excellent thermal shock resistance in a single, easy-to-install product. Imperial World Trade supplies castable refractories for flow control applications as part of its complete steel plant consumable portfolio.
- High Al₂O₃ Content: Alumina content ranging from 70% to 90% provides the slag resistance and refractoriness required for direct steel contact zones.
- Low Cement Formulation: Reduced CaO content minimizes low-melting phase formation, improving performance at continuous casting temperatures above 1,600°C.
- Low Porosity: Dense, vibration-cast matrix prevents slag infiltration and molten metal penetration into the lining structure.
- Thermal Shock Resistance: Engineered aggregate combination absorbs thermal cycling stresses during ladle filling, casting, and cooling sequences.
- Tundish Safety Lining: Specific grades formulated as tundish safety or permanent linings beneath the working lining for secondary containment.
- Rapid Drying Schedule: Optimized moisture content and bonding system allow controlled heat-up without steam spalling during initial firing.
Imperial World Trade supplies flow control castable refractories with complete Technical Data Sheets covering CCS, bulk density, PLC, and maximum service temperature, supporting your refractory engineering team from specification through to commissioning.
