High Refractoriness Magnesia Bricks For Steel / Cement / Ceramic Plant
High Refractoriness Magnesia Bricks For Steel / Cement / Ceramic Plant
Description:
The directly bonded 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 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.
Advantage:
The directly bonded magnesia-chrome brick has high temperature resistance, good corrosion resistance, thermal shock resistance and bulk stability under high temperature etc .
Application :
The directly bonded magnesia-chrome brick mainly used in metallurgy(open hearth,EAF), non-ferrous (metall-urgyfurnace ) , buildings and materials (cement rotary kiln,glass kiln) etc.
