Including magnesia brick, magnesia chrome brick, calcium magnesium brick, magnesia carbon bricks, spinel brick, magnesia alumina brick.

It’s made from dense magnesite clinker. By high pressure shaping and high temperature firing, it has a good slag resistance when servicing electric arc furnaces. This brick is a realistic lining material for electric furnace, lime kiln, non-ferrous metal metallurgical furnace. 

Magnesite Brick Features:
1. High refractoriness, multiply mineral composition;
2. Good thermal conductivity, strong slag erosion resistance.
 
Magnesite Brick  Application:
1. The regenerative chamber for the ceramic frit kiln, sodium silicate and glass furnace;
2. The furnace lining of iron and steel industry, such as ferroalloys furnace, metal mixer;
3. The non-ferrous metallurgy industrial furnace lining, such as the furnace copper, lead, zinc, tin, etc;
4. The lining for cement rotary kiln;
5. Calcining kiln, shaft kiln and tunnel kiln for refractory material industry
