China New Arrival China Magnesia Refractory Bricks - Fused magnesia and graphite resin – bonded refractory magnesia carbon bricks – Rongsheng factory and manufacturers | Rongsheng

Magnesia carbon bricks are a kind of unburned carbon composite refractory, which 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. Magnesia carbon brick has features of low porosity, slag erosion resistance, thermal shock resistance and higher high-temperature strength. As a kind of composite refractory, magnesia carbon fire bricks utilize strong slag corrosion of magnesia and high thermal conductivity and low expansibility of carbon efficiently, can make up for the biggest disadvantage of worse spalling resistance of magnesia.

Properties of Magnesia Carbon Bricks

• Good high temperature resistance property,
• Good thermal shock resistance,
• Good heat stability,
• Good thermal conductivity,
• Low high-temperature creep,
• Strong slag erosion resistance.

Composition of Magnesia Carbon Bricks

Magnesia carbon bricks 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. So magnesite carbon bricks have properties of slag corrosion resistance, thermal shock resistance, thermal conductivity and etc.

Magnesia Carbon Bricks Manufacturing Process

According to cold mixing techniques with compound tar binding agent becomes harden and gets the necessary strength, thus form isotropous vitric carbon. Magnesia carbon bricks are made of pitch binding agent, which have higher high temperature plasticity because of forming anisotropic graphitization coke structure in the pitch carbonation process. This kind of carbon does not show the thermoplasticity that can duly remove amount of stress in the process of lined firing or operating.
