Magnesia Carbon Brick is a type of composite refractory material formed by high-temperature curing with high-purity magnesia (MgO) and flake graphite as the core raw materials and resin as the binder. They combine the slag resistance of magnesium oxide with the thermal shock resistance of graphite, serving as the "high-temperature protective armor" for modern steel metallurgical equipment.
Performance Advantages
• Slag Resistance
The low wettability of graphite effectively prevents the penetration of CaO-SiO2 system slag, reducing the erosion rate by 60% compared to ordinary magnesia bricks.
• High Temperature Resistance
98% fused magnesia ensures structural stability at high temperature, and the compressive strength at 1500℃ remains above 70% of the room temperature value.
• Thermal Shock Resistance
The high thermal conductivity of graphite can quickly release thermal stress and greatly improve the thermal shock resistance.
Application
• Metallurgical Industry: Converter, electric furnace, ladle and other metallurgical equipment;
• Building Materials Industry: Cement rotary kiln, glass furnace;
• Chemical Industry: Coal chemical conversion furnace; Non ferrous metal smelting furnace.
The HX series magnesia carbon bricks produced by our company are designed and manufactured according to different usage parts and conditions of metallurgical equipment such as converters, electric furnaces and ladles. They are made from high-purity, high-density, large-crystalline magnesia and high-purity graphite as raw materials, and are produced through a high-pressure molding process. Therefore, they have excellent slag resistance and spalling resistance, which can greatly improve the service life of these metallurgical equipment.
