Magnesia-Carbon Brick
|
Taking high purity dead burned magnesite and natural high purity graphite as feed materials and high quality phenolic resin as binder, this product is a unfired brick that is made through high speed blending, evacuated high pressure shaping, heat treating and other processes.
It is featured by dense matrix structure, reasonable phase distribution, good properties of anti-spalling, anti-corrosion, high temperature volume stability and heat conductivity. It is mainly used in converter, refining furnace, high power and ultra-high power electric arc furnace and other furnaces.
