High strength refractories magnesium oxide insulating fire brick for heating furnace are designed and manufactured as per the different usage parts and working conditions of electric furnace, converter and ladle. It is shaped by high purity and high compact or large crystalline fused magnesia and high purity graphite as main materials and phenolic resin as binder.This kind of lime kiln used magnesia brick is mainly applied for the lining parts of electric furnace and converter.Directly touching molten steel and slag,it has the advantages of high strength,high slag resistance,good thermal stability and high refractoriness.According to melting conditions,different grades of magnesia carbon refractory brick should be chosen for the various usage parts of furnace body and ladle.
