Buy low cost Magnesite Chrome Bricks made from top qualified magmesia mixed with chrome concentrate. The content of chrome can be adjusted according to the customer’s requirement. The bricks have a good thermal stability and high temperature performaance, and are widely used in cement kiln or non-ferrous metallurgical furnace,etc.
 
Magnesia Chrome bricks include Common Mgo-Cr2O3 bricks, Direct Bonded Bricks, Semi-Rebonded Bricks and Rebonded Bricks. They show the features of excellent resistance against slag, good erosion resistance and thermal shock resistance. They can be applied in AOD/VOD refining furnace, DH/RH degassing device, EAF, and lining of nonferrous metal converter, glass and cement kilns.
 
The direct bonded magnesite-chrome brick, semi-rebonded magnesite-chrome brick and electrofused rebonded magnesite brick aremade from impurity raw materials that are pre-burned or fused. The bricks are formed through fine blending,heavy pressing, fired in ultra high temperature tunnel kiln, and you can find out that the brick structure is in good grain compound,dtrength and volume stanbility which is widely used in large – scale cement rotary, secondary refining vessels as RH, VOD, AOD, and non-ferrous metallurgical furnace or glass-making tanks, etc.
