Magnesia Carbon Brick  descriptions from the supplier

Magnesium-carbon bricks are composite refractory materials mainly composed of magnesium oxide (60% - 90%) and carbon (10% - 40%). They possess characteristics such as high temperature resistance and resistance to slag erosion, and are widely used in high-temperature industrial fields such as steel and glass production.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Magnesia Carbon Brick parameteres

Magnesium-carbon bricks are mainly composed of magnesium powder (such as electrolytic magnesia, high-purity magnesia) and graphite powder, which are mixed in a certain proportion. Phenolic resin and other binders are added, and they are formed through high-pressure molding without the need for sintering. The key component ratios are as follows:

1. Magnesium oxide 60% - 90% - providing fire resistance and chemical erosion resistance

2. Carbon 10% - 40% - enhancing thermal conductivity and thermal shock resistance

3. Additives ≤ 5% - inhibiting carbon oxidation (such as aluminum, silicon metals)

 

features Magnesia Carbon Brick

The core features of magnesia-carbon bricks:

1. High temperature resistance: The melting point of magnesium oxide is approximately 2800℃, while the melting point of carbon exceeds 3000℃, enabling stable operation at temperatures above 2000℃.

2. Resistance to slag erosion: The low wetting property of graphite reduces the penetration of molten slag, and magnesia resists erosion by alkaline slag, suitable for the linings of steel ladles and converters.

3. Good thermal conductivity: The high thermal conductivity of carbon helps to distribute heat evenly, protecting the equipment structure.

applications of  Magnesia Carbon Brick

Magnesia Carbon Brick Mainly used in the following scenarios:

Steel smelting: Used for the lining of converters and electric furnaces, able to resist high-temperature corrosion and have a long lifespan
Glass industry: Used for the lining of glass kilns, able to withstand chemical corrosion and stable heat conduction
Aluminum electrolytic cell: Used as the lining material, able to withstand high temperatures and resist electrolyte erosion
