 MAGNESIA CARBON BRICKS

Magnesia carbon brick with high melting point of alkaline oxide, magnesium oxide (melting point 2800 ℃) and hard to slag invasion of high melting point carbon materials as raw materials, all kinds of oxide additives.Carbon composite refractory materials with carbon binding agent.

With high purity magnesia powder, carbon materials (including graphite) and tar pitch or resin as raw material, after heat ingredients, mixing, molding, then through above 300 ℃ or 1000 ℃ calcination.

In order to inhibit the oxidation of carbon in bricks, it is often added with aluminum, silicon, magnesium and other metals or boron nitride, and the amount is not more than 5%.

APPLICATION FOR EAF, LADLE, CONVERTER

It is mainly used in furnace lining of steelmaking oxidation converter, outlet of steel outlet, hot spot of high power electric furnace wall, lining of furnace outer furnace and steel drum slag line.

ADVANTAGE

It has excellent slag resistance, slag penetration, thermal shock stability and thermal conductivity.
