Fused Cast Block Magnesia Chrome Brick Manufacturer

These materials are combined with various non-oxide additives and then fired at high temperatures to form the bricks. As a composite refractory material, magnesium-carbon bricks effectively utilize the strong slag-erosion resistance of magnesium and the high thermal conductivity, low expansion properties of carbon, while compensating for the major drawback of poor magnesium's anti-peeling property.

Advantages of Magnesium Carbon Brick

Outstanding high-temperature resistance

Magnesium carbon bricks possess excellent high-temperature properties and can be used for a long time at temperatures above 1200 °C. 

Corrosion resistance

Magnesium-carbon bricks possess excellent corrosion resistance, and thus can be used in strong corrosive environments such as those containing acids and alkalis. 

Good thermal shock resistance

Magnesium-carbon bricks have excellent thermal shock resistance at high temperatures, capable of withstanding significant temperature gradient changes without cracking. 

Good thermal conductivity

Magnesium-carbon bricks have excellent thermal conductivity, which can evenly distribute and transfer heat, thereby facilitating the improvement of production efficiency.

Application of Magnesium Carbon Brick

Steel Smelting

Magnesium carbon bricks are widely used as lining materials in various equipment in the steel smelting industry, such as converters, electric arc furnaces, and steel tanks. They can withstand the high temperatures and corrosion caused by molten metals during the smelting process. 

Aluminum smelting

Magnesia-carbon bricks are also used in the electrolytic cells of the aluminum smelting industry. The electrolytic cell is the main equipment for electrolyzing aluminum, and magnesia-carbon bricks have excellent refractory properties and conductivity in the electrolytic cell. 

Steel ladle maintenance

During the maintenance and repair of steel ladles, magnesia-carbon bricks are commonly used to restore the refractory linings on the bottom and sides of the ladles. This helps to extend the service life of the ladles and ensure the quality of the molten steel. 

High-temperature industrial furnaces

Magnesia-carbon bricks are suitable for various high-temperature industrial furnaces, such as oil refining furnaces, chemical furnaces, and glass melting furnaces. They can withstand high-temperature environments, chemical erosion, and thermal shock stresses. 

Mechanical manufacturing industry

Magnesium-carbon bricks can be used to manufacture high-performance electrodes, semiconductor industrial furnace materials, high-boron alloys, etc. 

High-temperature reactor

Magnesium-carbon bricks can also be used in high-temperature reactors, such as the calcining furnaces in the production process of aluminum hydroxide and the conversion furnaces in the ammonia synthesis process.
