  3. Refractories for the Tundish continuous casting

 REFCAST LC- 80

Alumina based low cement refractory castable for the tundish lining.

High refractoriness and very good behaviour throughout thermal cycles.

Density : 2,60 Kg/dm3

Thermal Conductivity : 2,20 W/m.K

 TUNDFIL

Tundfil 25E is a refractory dry powder based on dead-burned magnesite (MgO) and olivine (ΜgO.SiO2), used in the expendable lining of the tundish. Its special formulation ensures very good insulating properties, resistance to chemical attach from the metal and many hours of continuous casting.

TUNDTILES

 

 

The insulating tiles TUNDTILES are a preshaped, refractory silicate material for the inner lining of the tundish’s surface, that comes into contact with molten steel. The tiles are refractory, insulating, with low density (approx. 1,10 Kg/dm3) but adequately strong so that they are easy to be used with or without mechanical support.

Recommended for continuous casting up to 6 hours
