Rebonding magnesia chrome bricks of synthesis method is adopted fused magnesia chrome spinel as the main raw material, after high-pressure forming, high temperature sintering made a good erosion resistance performance of high-grade produces excellent special.

Classification of Rebonding Magnesia Chrome Brick

As the basic of raw materials of fused rebonded magnesia chrome bricks, synthetic magnesia chromite clinker falls into two types: electricity melting methods and sintering methods.

Material of Fused Rebonding Magnesia Chrome Bricks

Fused magnesia chrome sand use high purity raw materials such as special grade magnesite, high purity light magnesia or dead burned magnesia, and carefully chosen chrome ore, etc.

Magnesia chromite clinker that synthesized by sintering methods use high purity light magnesia and chromium concentrate as raw materials, produced by mixing, compacting, firing in high temperature oil shaft kiln.

Fused rebonded magnesia chrome bricks should be fired at 1800～1850℃ ultra-high temperature.

Properties of Rebonded Magnesia Chrome Bricks

1. high purity
2. less impurities
3. low apparent porosity,
4. low permeability
5. high density
6. high temperature strength
7. good volume stability.

Applications of Fused Rebonding Magnesia Chrome Bricks

Fused rebonded magnesia chrome bricks are widely used in where the part of refining furnace suffers the most serious slag corrosion.

1.  Tuyere zone of AOD furnace;
2. Lower vessel and snorkel of RH vacuum chamber;
3. Slagline of VOD furnace.
