Good Thermal Conductivity Magnesia Carbon Brick For Buildings And Materials
1 Mg-C brick has high refractoriness
2 high basic slag resistance
3 good thermal conductivity
Transfer of coal use AL and SI composite metal powder as anti-oxidants, which can effectively
prevent the Mgo and MgO-C oxidation, AL and SI first and O2, CO2 responses, followed by the
reaction of oxidants and slag Mgo AL203 and SIO2, to prevent, weaken the erosion of slag on the brick,
decarburization layer formation and the role of high basicity slag, making difficult Mgo reaction with
the C and the slag is conducive to slag corrosion resistance properties of Mgo-improve
