Production process:
high quality fused magnesia, natural flake graphite as the main raw material, organic matter as a binder, reasonable addition of anti-oxidation the chemical agent is prepared by mixing, high pressure molding and heat treatment. High bulk density, low apparent porosity, excellent slag resistance and spalling resistance.
Main application:
for ordinary EAF, high power and ultra high power masonry of the working layer of the EAF.
