Description for Magnesia Chrome Brick

Magnesia Chrome Brick is a kind of refractory materials products with MgO and Cr2O3 as its main chemical component and with periclase and spinel as its main mineral constituent. This type of brick has properties of high refractoriness, great high temperature strength, strong basic slag erosion resistance, great thermal stability and certain flexibility to acid slag.

Magnesite-chrome brick is manufactured with raw materials of magnesite clinker and chromite, in which purity of magnesia raw material must be high as possible and chemical component of chromite should be 30~45% Cr2O3 and ≤1.0~1.5% CaO.

Properties of Magnesia Chrome Brick

  • Good thermal shock resistance
  • Strong furnace slag erosion resistance
  • High temperature strength
  • High flexibility
  • Low thermal conductivity

Application of Magnesia Chrome Brick

  • Magnesia chrome brick is mainly used in metallurgical industry, such as building open-hearth furnace, furnace top of electrical furnace, out of finery and all kinds of non-ferrous smelting furnace.
  • High temperature position for furnace wall of ultra high power electric furnace adopts fused cast magnesite chrome brick.
  • Strong erosion area of finery furnace adopts magnesite-chrome brick made of synthetic compost
  • Strong erosion area of nonferrous metals smelting furnace adopts fused cast magnesite chrome brick and magnesite-chrome brick made of synthetic compost
  • Magnesia chrome brick is also used in position of burning zone of rotary cement kiln and regenerative chamber of glass kiln.

Manufacturing Process Of Magnesia Chrome Brick

Manufacturing process of magnesia chrome brick is similar to magnesia brick. Adopt magnesite-chrome brick made of bonded common sintered material to eliminate loose effect caused of the expansion when producing the spinel by the reaction of MgO and Cr2O3, Al2O3 or FeO. Moreover, there is also unburned magnesia chrome brick such as unburned magnesia chrome brick made of inorganic magnesia saline solution. Manufacturing process of unburned magnesia chrome brick is simple and cost low. This kind of brick has great thermal stability, but its high temperature strength is lower than burnt magnesia chrome brick.
