What are the properties of magnesia carbon bricks?

Magnesia carbon bricks are a type of refractory brick made from high-purity fused magnesia, graphite, and various additives. They have excellent high-temperature resistance, thermal shock resistance, and slag corrosion resistance, making them ideal for use in the lining of steelmaking furnaces such as electric arc furnaces, converters, and ladles. The following are some of the properties of magnesia carbon bricks:
1.High-temperature resistance
Magnesia carbon bricks can withstand high temperatures of up to 1800°C without losing their strength and durability.
2.Thermal shock resistance
Magnesia carbon bricks have good thermal shock resistance, which means they can withstand rapid temperature changes without cracking or breaking.
3.Slag corrosion resistance
Magnesia carbon bricks have excellent resistance to slag corrosion, making them ideal for use in steelmaking furnaces that are exposed to corrosive slag.

4.Low thermal expansion
Magnesia carbon bricks have a low coefficient of thermal expansion, which means they are less likely to deform or crack due to temperature changes.
5.Good electrical conductivity
Magnesia carbon bricks have good electrical conductivity, which makes them ideal for use in electric arc furnaces.
6.Good oxidation resistance
Magnesia carbon bricks have good oxidation resistance, which means they can maintain their properties even after prolonged exposure to oxygen-rich environments.
Overall, magnesia carbon bricks are widely used in the steelmaking industry due to their excellent high-temperature performance and resistance to slag corrosion. They play a critical role in ensuring the safe and efficient operation of steelmaking furnaces and other high-temperature equipment.
