Detailed Product Description

Magnesia carbon brick

Magnesia carbon brick is based on magnesium oxide and carbon as the main component of the refractory material. Magnesium containing 60% ~ 90%, carbon 10% ~ 40%.magnesia carbon brick have excellent corrosion resistance to slag, slag permeability, thermal shock stability and thermal conductivity. Apparent porosity of 3% ~ 10%. The use of high purity magnesia powder, carbon materials (including graphite) and tar pitch or resin,etc, After batching, thermal mixing, molding, and then at 300 or 1000 about baking from above.In order to restrain the oxidation of carbon, often add aluminum, silicon, magnesium and other metal or boron nitride, the amount of not more than 5%. Mainly used in steel-making converter oxidation of the lining, high-power electric furnace hot part of the wall, as well as the secondary refining furnace lining, Sheng-line positions of steel slag
