Direct Bonded Chrome Magnesia Brick Refractory Fire Resistant Bricks

Quick Detail:

♦ High strength

♦ Corrosion resistance

♦ Erosion resistance

♦ Excellent slag resistance

♦ Good thermal shock stability

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℃,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

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.
