Refractory for Nonferrous material

Basic brick for non-ferrous metals industries.
Basic brick for non-ferrous metals industries is made of dead burned magnesia and purified chrome ore. The process of high-pressure press machine and ultra high temperature tunnel kiln manufactures them. This product has good resistance to both of corrosion and volume change at high temperature. They are widely used in non-ferrous metal factory and various high-temperature furnaces.
