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.

Advantage:Magnesia bricks, magnesia-alumina bricks and magnesite-zircon brick etc are the main products of basic refractories. The products have the properties of bearing high temperature, high refractoriness under load and good resistance to alkali

Application:They are widely used in the basic zone of metallurgical furnaces, nonferrous furnaces and regenerator of glass furnaces

Q:Application of electric high temperature regulating valve?
Many kinds of refractory materials, usually by refractoriness level is divided into ordinary refractory materials (1580 to 1770 DEG C), advanced refractories (1770 to 2000 DEG C) and special refractories (more than 2000 DEG C); according to the chemical characteristics into acid refractory material, refractory materials and basic refractory materials. In addition, there are refractories for special occasions.
