To magnesium oxide and carbon as the main component of the refractory.

Containing 60% to 90% magnesium oxide, carbon 10% to 40%.

Has excellent resistance to slag corrosion, slag penetration, thermal shock resistance and thermal conductivity. Apparent porosity was 3% to 10%.

High purity magnesite powder, carbon materials (including graphite) and the tar or resin, such as raw materials.

The ingredients, hot mix, forming, and then by about 300 º Cor above 1000 º Croasting.

To suppress the oxidation of carbon bricks, often add aluminum, silicon, magnesium and other metal or boron nitride, addition of not more than 5º C.

Oxidation converter is mainly used for lining steel, the steel export, high power electric furnace hot part of the wall, and the refining furnace linings, ladle slag line area and so on.
