EAF Refractory Magnesia Chrome Brick With Good Thermal Shock Resistance
Good Thermal Shock Resistance of Refractory Magnesia Chrome Brick for EAF
Description
The fused-rebonded magnesia chrome brick is made with sintered magnesia and refractory level chrome ore as raw materials. The space between refractory grains is bonded with silicate.The refractoriness of magnesia chrome bricks are more than 2000°C,and the refractory under load is a above 1550°C.Good steady volume in high temperature , the performance of meeting sudden cold and sudden hot is better than magnesia bricks.
Advantage:
The fused-rebonded magnesia chrome brick has high temperature resistance, good corrosion resistance, thermal shock resistance and bulk stability under high temperature etc
Application:
The fused-rebonded magnesia chrome brick mainly used in metallurgy(open hearth,EAF), non-ferrous (metall-urgyfurnace ) , buildings and materials (cement rotary kiln,glass kiln) etc.
