Product Description

 Magnesia Carbon Brick for Electric Arc Furnace

                       Magnesia Carbon Brick for Electric Arc Furnace
magnesia carbon brick description:
Refractory magnesia carbon brick with magnesium oxide and carbon as the main component. Magnesium oxide containing 60% ~ 90%, carbon 10% ~ 40%. With excellent corrosion resistance by slag, slag, thermal stability and thermal conductivity of penetration. The apparent porosity was 3% ~ 10%. Using high purity magnesia powder, carbon materials, including graphite) and coal tar pitch or resin as raw material, through proportioning, thermal mixing, molding, the 300 DEG C or 1000 DEG C above roasting.
Magnesia carbon brick is with high melting point alkali oxide magnesium melting point (2800 degrees Celsius) and difficult to be slag infiltration of high melting point carbon material as raw material, add a variety of non oxide additives. No charcoal composite refractories with carbon bonded together.
