Product Description
High Refractoriness Magnesite Chrome Bricks for Steel VOD
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 domestic so called magnesia –Chrome bricks .
The refractoriness of magnesia chrome bricks are more than 2000℃,and the refractory under load is a above 1550℃.Good steady volume in high temperature , the performance of meeting sudden cold and sudden hot is better than magnesia bricks. According to different requirements the contents of the Cr2O3 can be changed.
Magnesite Chrome Bricks Feature
Steel making furnace use non-sintered magnesite-chrome refractory bricks.
1. Raw material:
Magnesite grain and chrome ore
2. Producing process:
Mull, mould, dry, cryogenic processing, finished.
2. Highlight:
1). Excellent Resistant Thermal shock performance.
3. Properties: (See attached table)
Magnesite Chrome Bricks Application
The direct-bonded magnesia chrome brick is widely used in the cement rotary kilns, regenerator of the glass furnace, lining of the steel making electric furnace, permanent lining of the RH upper slot and bottom slot, barrel of VOD furnace, non-ferrous metallurgical furnace, lining of the limekilns, metal mixer etc.
