magnesia carbon bricks . Our high volume output, combined with stringent manufacturing methods, has made us a strategic Magnesia carbon brick is a no-burn alkaline refractory material. It enhances corrosion resistance and slag resistance. The product range is based on magnesia composite materials. These bricks show excellent resistance to thermal shock and corrosion at high temperatures and are widely used in the steel industry. Its high melting point and resistance to hydration make it an ideal refractory material. Steelmaking requires extreme chemical, thermal and mechanical conditions that require materials with high performance that can withstand the action of steel and slag. Both magnesia carbon and magnesia alumina carbon are capable of providing such properties. In addition to manufacturing standard brick sizes (MC 8/10/12/14/18), we are able to produce specialized shapes to suit all reformer and electric arc furnace designs.

Silica brick is a kind of acid refractory mainly made from tridymite, cristobalite and a small amount of residual quartz as well as glass phase. The raw refractory material is natural silica sand whose SiO2Â content should be more than 96%. The higher SiO2Â content in silica sand, the higher temperature silica bricks resist, its refractoriness under load is as high as 1640 ~ 1670. Glass kiln silica brick has high temperature and volume stability, no pollution to glass liquid, chemical corrosion resistance, small bulk density, and can reduce the weight of furnace body.
