High-quality Low Price Magnesia-carbon Bricks

Overview of Magnesium-carbon bricks 

Magnesium-carbon bricks are refractory materials composed mainly of magnesium oxide (60% - 90%) and carbon (10% - 40%). They possess properties such as high temperature resistance and resistance to slag erosion, and are widely used in high-temperature industrial scenarios such as steel-making converters, electric furnaces, and steel ladles. However, they have issues such as increased carbon content and structural peeling.                                                                                                                                                   

                                                                                       

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The core components and performance characteristics of magnesium-carbon bricks

Magnesium-carbon bricks are mainly composed of high-melting-point magnesium oxide (MgO, with a melting point of 2800°C) and carbon (such as graphite, with a melting point above 3000°C). There is no mutual melting point relationship between them, preserving their respective advantages in high-temperature resistance. The key performance characteristics include:

1.Resistance to slag erosion: MgO has strong resistance to alkaline slag. Graphite reduces the wetting property of the molten slag. Spinel reacts to block pores and capture FeO and MnO.
2.Thermal stability: The low expansion and high thermal conductivity of carbon, combined with the volume expansion during the formation of spinel, reduces thermal shock damage.
3.Physical properties: Porosity is 3% to 10%. High compressive strength at room temperature, but high carbon content leads to a large thermal conductivity.

applications of magnesium-carbon bricks

1.Ingot/electric furnace lining, used in steelmaking oxygen converters and high-power electric furnaces, can withstand high-temperature erosion and corrosion resistance.
2.Steel ladle slag line, used in large and medium-sized refining ladles, can resist slag penetration and has good integrity.
3.External refining furnace, used in LF refining system and ladle, can adapt to arc heating and stirring environments.
