High-Quality Control for Kerui Magnesia Alumina Carbon Bricks

• Kerui’s magnesia alumina carbon bricks are made from premium raw materials, including bauxite, corundum, fused magnesia, and graphite.
• The raw materials are precisely proportioned and uniformly mixed.
• The manufacturing process features automated operations for pressing, demolding, mold locking, and injection. With accurate volumetric feeding, bidirectional pressing, and hydrostatic pressure, the refractory bricks achieve high density, stable quality, and precise dimensions.
• The bricks are fired at high temperatures in a 168-meter-long tunnel kiln.
• The final products undergo grinding, measurement, and inspection to ensure quality.

Features of Alumina Magnesia Carbon Brick

• Resistance to slag erosion;
• Resistance to molten steel corrosion;
• Excellent spalling resistance;
• Good thermal stability;
• Low thermal conductivity;
• Strong oxidation resistance;
• Superior insulation performance, better than magnesia-carbon bricks;
• Moderate residual linear expansion;
• Better spalling resistance compared to magnesia-carbon bricks in ladles;
• Enhanced matrix;
• Excellent structural integrity;
• High resistance to thermal shock.

Note: To enhance the oxidation resistance of alumina magnesia carbon bricks, appropriate additives such as silicon powder, aluminum powder, silicon carbide powder, or ferrosilicon powder can be incorporated.

Application of Alumina Magnesia Carbon Bricks

Application of alumina magnesia carbon bricks is widely in metallurgical equipment such as ladle furnaces and refining ladles. They are mainly applied to the side walls, slag lines, and bottoms of ladles. During use, they can adsorb non-metallic impurities in the molten steel, achieving the goal of steel purification. They are a high-quality alternative to corundum and high-alumina refractory bricks.

• Steel Industry: Converter linings, electric arc furnace linings, ladles, etc.
• Non-ferrous Metal Metallurgy: Furnace linings for the smelting of non-ferrous metals like copper and aluminum.
• Petrochemical Industry: Petroleum cracking furnaces, catalytic cracking units, etc.
• Glass Industry: Glass melting furnaces, etc.
