Special Function Refractory Castable for Aluminum Melting

It is a high purity silicon carbide based LCC designed to be applied in harsh fusing conditions like strong compact and running launder, reverb furnace’s tap hole and stirring tank with its’ high abrasion resistance, high heat conducting and high anti-penetration properties.

Suitable conditions and features

High purity alumina based LCC used in aluminum furnace lower side walls, hearth and belly band areas with high strength, resistance to molten aluminumalloys and salt fluxes.

Used for ladles, covers, coreless furnace rings,non-ferrous furnace ceilings, doors, uppercases, launders, forge and heat treatment. Higher grade materials are available for more harsh working conditions.

 

Mullite based LCC  used in upper sidewalls, jambs  and roofs of aluminum melting  furnace, tundish linings and pads, coreless furnace rings, non-ferrous uppercases, and launders.  

Alumina based LCC with high corrosion resistance serviced as ladle& tundish lining, impact pads,  non-ferrous channel furnace uppercases, burner ports, precast shapes.

Alumina  based LCC used in all aluminum melting furnaces except the coreless furnace'  lining for molten aluminum and zinc alloys contact parts. Also used as aluminum ladle'  lining.

High  grade SiC based LCC with superbthermal conductivity, resistance to  aluminum-based alloy,  suit for high abrasion application asaluminum outlet,  launder and stir well for  reverb furnace.
