Taphole Clay
Thermax® N990 replaced graphite in a taphole clay composition resulting in decreased porosity and increased cold crushing strength.
Thermax® application
Thermax® carbon black can improve performance of monolithic, castable, carbon brick and basic carbon brick refractories. It can enhance resistance to thermal shock, heat, chemicals and active slag, increase refractory density, and improve in-situ carbide formation. Castables containing Thermax® require less water to reach normal casting flow, resulting in higher density and less porosity.
