Magnesia Carbon brick is resin-bonded brick made from dead-burned or fused magnesia and graphite. Anti-oxidant is added if required. Magnesia Carbon brick has good performance in thermal resistance, corrosion resistance and spalling resistance. Widely used in converters, EAFs, ladles and refining furnaces.
Magnesia Carbon brickis a very mature product in our area. As our area has 1/4 world storage of best quality Magnesia ore, we can provide as good quality as European Mg-C bricks with competitive prices. We also provide basic refracotry lining solution for CONVERTER, EAF, LF, LADLE, etc. these industrial furnaces.
The following are typial properties as per Chinese latest version standard. We also provide customer-tailored products as per customer special reuirements.
