foundry sand chromite plant
The main chemical composition of chromite sand is cr2o3, which has the characteristics of stable volume and high thermal conductivity when the sand body is heated. In contact with molten metal, it not only has good alkali slag resistance, does not react with chemical substances such as iron oxide, but also has solid-state sintering characteristics, which can well prevent the infiltration of molten metal and avoid sanding Defective, raw sand progressively forming cores and coatings for a variety of stainless steels, alloy steels and carbon steels
