Magnesia-Carbon Brick wholesale

Magnesia-Carbon Brick China uses high melting point basic oxide magnesium oxide (melting point 2800°C) and high melting point carbon material that is difficult to be infiltrated by slag as raw materials, adding various non-oxide additives. Non-burning carbon composite refractory material combined with carbon binder.

Sinometal Magnesia carbon bricks are made of high melting point basic oxide magnesium oxide (melting point 2800°C) and high melting point carbon materials that are difficult to be infiltrated by slag as raw materials, adding various non-oxide additives. Non-burning carbon composite refractories combined with carbon binder. Magnesia carbon bricks are mainly used in the lining of converter, AC arc furnace, DC arc furnace, slag line of ladle and other parts.

As a composite refractory material, wholesale magnesia-carbon brick effectively utilizes magnesia's strong resistance to slag erosion, carbon's high thermal conductivity and low expansion, and compensates for the biggest shortcomings of poor resistance to magnesia.

The main features are: good high temperature resistance, strong slag resistance, good thermal shock resistance, and low high temperature creep.

The traditional magnesia-carbon bricks made with a synthetic tar binder according to the cold mixing process harden and acquire the necessary strength during the tar damage process, thus forming isotropic glassy carbon. This kind of carbon does not show thermoplasticity, which can relieve a large amount of stress in a timely manner during baking or operation of the lining. The magnesia-carbon brick produced with the asphalt binder has a high temperature plasticity due to the formation of an anisotropic graphitized coke structure during the asphalt carbonization process.
