It is resin-bonded and made with fused grain magnesia, high purity magnesia and high purity flake graphite. They have excellent corrosion resistance, thermal shock resistance and spalling resistance. They wide applications and can be used in key locations of thermal processing equipment such as BOF, EAF, LF and so on.
