Magnesia carbon bricks

MgO (%)≥97～98, C (%)≥7～18
Bulk density (g/cm³)≥2.95～3.05
Apparent Porosity(%)≤3

Application:

Magnesia carbon bricks are the most widely used refractory bricks for steel making furnace. Hitech Material magnesia carbon bricks can be used as working linings of converters, EAF and ladle, etc.

　　Magnesia carbon refractory bricks are produced by using fused magnesia and flake graphite as main materials, organic compounds as bonding agent, adding non-oxide additives, thus through mixing, high pressure pressed and heat treatment process.
