High Quality Magnesia Carbon Bricks Manufacturer

Magnesia carbon bricks is mainly made of high melting point basic oxide magnesium oxide and high melting point carbon material which is difficult to be infiltrated by slag as raw materials, and then various non-oxide additives are added. Finally, the non-burning carbon composite refractory is made of carbon binder. Often used in converter, ac furnace, dc arc furnace lining, ladle slag line and other parts.

Magnesia carbon bricks as a kind of composite refractory material, makes good use of magnesia's strong resistance to slag erosion, high thermal conductivity and low expansibility of carbon, and compensates the biggest shortcoming of magnesia's poor flaking resistance. Its main characteristics are good high temperature resistance, strong slag resistance, good thermal shock resistance, low temperature creep.

The series of refractory brick products are mainly used for converter, ac arc furnace, dc arc furnace lining, ladle slag line and other parts. The main raw materials of the brick include fused magnesia or sintered magnesia, flake graphite, organic binder and antioxidant.

The refractory materials used in the early ladle slag line were directly bonded magnesia-chrome bricks, electrofused fused magnesia-chrome bricks and other high quality alkaline bricks. After mgo-c brick was successfully used in converter, mgo-c brick began to be used in slag line of refined ladle, and good results were obtained.

The main problem caused by the decrease of carbon content in magnesia-carbon refractory brick is the decrease of thermal shock stability and slag permeability resistance. As is known to all, the decrease of carbon content in magnesia-carbon brick leads to the decrease of thermal conductivity and the increase of elastic modulus, which leads to the deterioration of thermal shock resistance stability of brick. With the decrease of carbon content, the wettability of slag and molten steel is enhanced, and the permeability of slag and molten steel becomes worse.
