What are magnesia carbon bricks?
Magnesia Carbon Brick is a high-performance refractory material, mainly used in high-temperature industrial environments such as steel, ironmaking, glassmaking, إلخ. Its main components include magnesia (magnesium oxide, أهداب الشوق) and carbonaceous materials (such as graphite, فحم الكوك), and antioxidants and binders may also be added. Magnesia Carbon Brick has extremely high refractoriness, مقاومة التآكل, thermal stability and mechanical strength, and is suitable for furnace lining materials under high temperature conditions, such as converters, electric arc furnaces, ladles, إلخ. Through precise proportioning and advanced manufacturing processes, Magnesia Carbon Brick can provide excellent durability and performance, and is an indispensable material in modern high-temperature industries.
The national standard number of magnesia carbon bricks is GB/T 22589. The Chinese name of the standard is “طوب الكربون المغنيسيا” and the English name is “Magnesia carbon bricks”.

Production process of mag carbon brick
- Raw material selection: 98% sintered magnesia, 91% fused magnesia and natural flake graphite with a fixed carbon content of 94-95% and an ash content of 5%
- Raw material processing: crush and screen the sintered magnesia and fused magnesia blocks respectively, and grind part of the sintered magnesia into fine powder less than 0.088mm through a cylinder mill as a mixing material
- تجميع: prepare the raw materials according to a predetermined ratio
- خلط: mix in a strong sand mixer, and the order of adding materials is: magnesia aggregate-binder-graphite-fine powder and additives, and the mixing time is 15-45min
- Molding: use a molding machine to press the mixed raw materials into shape
- Drying and firing: dry and fire the molded magnesia carbon bricks to improve their strength and stability
