Product description:
Protective slag for mold casting high carbon refractory is dedicated covering slag for carbon steel slab continuous casting
Product features:
In order to meet low temperature of the high carbon steel liquidus and heat small in cast steel.Protective slag for mold casting high carbon refractory can reduce the melting temperature and make protective slag with corresponding melting characteristics and steady transfer heat speed. Seleting the suitable species of the carbon make composite carbon which can slow its surface speed of off carbon, Protective slag for mold casting high carbon refractory achieved good results.
