Description:
It 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°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
Specifications:
Direct-Bonded Magnesia-Chrome Brick
Main Application:It's mainly applied to line the sintering zone of the new dry-processing of cement kilns and glass tank furnaces as checkers and the other industrial furnaces.
