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?
- Magnesia brick has good resistance to alkaline slag and slag, refractory clay brick and brick high ratio. Mainly used in open hearth furnace, oxygen converter, electric furnace, non-ferrous metal smelting equipment and glass industry as well as some high temperature equipment. Magnesia chrome brick more resistant to alkaline slag, and thermal shock stability are much higher than the more widely used, magnesia, magnesia chrome bricks in iron and steel smelting and non-ferrous metal smelting industry has almost replaced the brick, chrome oxide containing (Cr2O3) can be spread, the magnesium chromium brick can easily sticking kiln the skin, so in the past 30 years, has been used with refractory preferred cement kiln, magnesia chrome brick in Cr2O3 water after the reaction of trivalent chromium into six chromium can cause the pollution on the water, facing gradually out of the cement industry market trends. Magnesia and magnesia alumina brick using alumina as raw materials, a magnesia brick compared to thermal shock resistance and high temperature creep performance, use parts and magnesia brick is almost the same. Dolomite brick and magnesia calcium brick performance is almost the same, dolomite brick using dolomite as raw material, calcium magnesium brick with synthetic calcium magnesium sand as raw materials, calcium oxide content in 15-30%, the other is the main component of Magnesium Oxide, with the function of purifying molten steel, usually only used for special steel smelting, the production process of magnesia calcium brick complex water and water steam, easy decomposition, not easy to save transportation, do preventive work must be used in the process of. Magnesia spinel brick is a kind of new products, mainly for the zone and transition zone of cement rotary kiln, will be the main products of the cement industry to replace magnesia chrome brick.
