Shaped Refractory Fire Magnesia Brick

 

Type:HY
Supply Ability:150T/D
Delivery:15-30days
Application:cement, electric power, metallurgy, chemical industry and other industry

 

 

description

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.
