Kerui Refractory mainly offers 26 types of magnesia carbon bricks. The main difference between these types lies in the content of carbon and magnesia oxide. Please choose the appropriate brick based on the characteristics of each type.
Magnesia carbon bricks are mainly composed of magnesia sand, graphite, resin, or tar asphalt as raw materials. These materials are mixed, pressed, and thermally plasticized to form magnesia carbon bricks. Bricks combine the high refractoriness of magnesia sand with the thermal conductivity and mechanical properties of carbon. They perform excellently in high-temperature applications.
Heat Shock Resistance
Kerui high-quality carbon has the characteristics of rapid heat absorption and dispersion, which helps reduce the impact of heat stress on bricks, thereby enhancing their heat shock resistance.
High Slag Corrosion Resistance
Kerui MgO-C bricks combine the characteristics of magnesia and carbon. It has high resistance to metal oxides and other corrosive substances.
High Temperature Resistance
In Kerui magnesite bricks, the refractoriness of high-quality magnesia is usually tested at - degrees Celsius. The combination of magnesia and carbon enhances its high-temperature resistance.
Strong Mechanical Strength
Kerui magnesia carbon bricks have high mechanical performance. It has good wear resistance. Additionally, it can withstand a certain degree of compressive strength and flexural strength.
Low Thermal Expansion
Kerui bricks have minimal volume changes when subjected to thermal expansion at high temperatures. It has good stability and is widely used in high-temperature industrial fields.
High Thermal Conductivity
Magnesia carbon refractory bricks rapidly conduct heat at high temperatures. It helps maintain temperature balance in the working environment, improving energy efficiency.

Steel Smelting Industry
In the steel industry, magnesium carbon bricks are widely used for their excellent performance in various equipment such as oxygen converters, electric arc furnaces, ladles, refining furnaces, tundishes, and slag pots. These bricks can withstand the high temperatures, corrosion, rapid temperature changes, high pressure, wear, and strong mechanical conditions present in the steelmaking process, allowing them to maintain stability in steel industry equipment production for extended periods.
Other Industries
In other industries, magnesia carbon bricks are also applied in alkaline working environments, including the cement, glass, and petrochemical industries. They are primarily used for lining cement kilns, flues, glass furnaces, glass ladles, refining equipment, and petrochemical reactors. These bricks can resist chemical corrosion from substances and gases, making them suitable for various alkaline high-temperature kilns or equipment.

Magnesia carbon refractory bricks containing magnesite and graphite flakes are used in basic oxygen furnaces and ladles in the steel industry. The selection and size distribution of raw materials, known as granulometry, affects the physical and mechanical properties of the bricks. Bricks with magnesite grains between 3-4 mm show better wear resistance than those with 5 mm grains. The optimal granulometry for general applications is a mixture with 0-4 mm grain sizes distributed as 20-30% over 2 mm, 35-40% between 0.5-2 mm, 10-15% between 0.2-0.5 mm, and 25-30% under 0.2 mm.
