The fused rebonded magnesia chrome brick is a high-grade refractory brick, which is made of electro-melting method for synthesizing magnesia-chrome spinel as a main raw material. It has excellent corrosion resistance, by high-pressure molding and high-temperature sintering. The application field of Fused Rebonded Magnesia Chrome Brick is similar to that of ordinary magnesia chrome brick.
Fused Rebonded Magnesia Chrome Brick has excellent anti-erosion performance. Its high-temperature performance is between fused cast magnesia chrome brick and sintered magnesia chrome brick. Its load softening temperature can reach 1700 °C.
Why Fused Rebonded Magnesia Chrome Brick Appear ?
At present, refractory materials for RH furnaces are mainly magnesia-chrome bricks. Compared with other refining equipment in the RH furnace, the refractory materials used in each part of the RH vacuum tank are subjected to the high-speed erosion of the molten steel and the sharp changes in temperature in addition to the high-temperature molten steel and slag. Therefore, more stringent requirements are imposed on refractory materials.
However, with the increase of smelting strength and the continuous change of smelting steel grades, the service life of existing magnesia chrome bricks can no longer meet the requirements of energy saving and consumption reduction. In order to solve this problem, RS refractory brick manufacturers have developed on the basis of the original magnesia chrome bricks to produce high-performance Fused Rebonded Magnesia Chrome Bricks. In order to improve the performance of existing magnesia chrome bricks, chromite chrome sand and chrome ore are the main raw materials with high content of Cr2O3 and high purity.
Application of Fused Rebonded Magnesia Chrome Brick in RH Furnace
High-performance Fused Rebonded Magnesia Chrome Bricks, used in the lower tank of the RH furnace, not only improves the life of the furnace, but also saves a lot of energy for steel production. It has played a role in energy saving and consumption reduction. Greatly saved the production cost of steel making.
