Magnesia Carbon Refractory Brick

Magnesia Carbon Refractory Brick

Magnesia carbon refraqctory bricks are made of high-pure magnesium sand powder, carbon materials (including graphite) and caramel asphalt or resin as raw materials. After the ingredients, heat mixing, and molding, they are baked by about 300 ° C or above 1000 ° C. The brick has the characteristics of anti-slag erosion, slag permeability, thermal shock stability, and thermal conductivity.

MgO(≥): 69% – 85%;
C (≥): 5% – 18%;
Bulk Density: 2.87g/cm³ – 3.15g/cm³;
Cold Crushing Strength: 30MPa – 50MPa;
