Focus on Producing All Kinds Of High Quality Refractory Fire Bricks !
Magnesia Carbon Bricks
Magnesia Carbon Bricks are a kind of refractory material with bonding of resin and raw materials of magnesium oxide and graphite. They have properties of low porosity, slag erosion resistance, thermal shock resistance and higher high-temperature strength. They are mainly used for Basic Oxygen Furnace, Slag Line of Ladle Furnace and Hot Spot of Electric-Arc Furnace.
Magnesia Carbon Brick, a kind of unburned carbon composite refractory, are manufactured with magnesium oxide of alkaline oxide with high-melting-point (2800℃) and carbon material with high melting point that is difficult to be eroded by furnace slag as the raw materials, and added all kinds of non-oxides additive and carbon binding agent.
As a kind of composite refractory, Magnesia Carbon Brick utilizes strong slag corrosion of magnesia and high thermal conductivity and low expansibility of carbon efficiently, which make up for the biggest disadvantage of worse spalling resistance of magnesia.
Traditional magnesia carbon brick that is manufactured according to cold mixing techniques with compound tar binding agent becomes harden and gets the necessary strength. Thus form isotropous vitric carbon. This kind of carbon does not show the thermoplasticity that can duly remove amount of stress in the process of lined firing or operating. They are made of pitch binding agent, which has higher high temperature plasticity because of forming anisotropic graphitization coke structure in the pitch carbonation process.
Magnesia Carbon Bricks Uses
The Refractory Bricks are mainly used for linings of converter, electric-arc furnace and direct current electric arc furnace, slag line of steel ladle and other position.
Magnesia Carbon Bricks Composition
Magnesia Carbon Brick is a kind of quality refractory materials. Their main components are magnesium oxide and carbon, of which magnesium oxide content is 60~90% and carbon content is 10~40%. This kind material is made of high purity magnesia particle, carbon material, tar, pitch or resin as the raw materials through high temperature baking. These Magnesia Refractory Bricks have properties of slag corrosion resistance, thermal shock resistance, thermal conductivity and etc.
