Features

Description:
High strength
Corrosion resistance
Erosion resistance
Excellent slag resistance
Good thermal shock stability

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℃,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
