Aluminium magnesia carbon brick is made of super high bauxite or corundum sand, magnesia and flake graphite as the secondary raw materials. Its characteristic is at low temperature in addition to the carbon has the advantages of high corrosion resistance and not easy to peel, but also because of the use of heat spinel and show the advantages of high residual line shrinkage rate, so it becomes a new development of high quality lining brick. Contains Al2O360% ~ 69%, MgO7% ~ 14%, C5% ~ 12%. It has good corrosion resistance of slag and thermal shock resistance. It has the advantages of anti-corrosion, anti-spalling, balanced corrosion, safe operation, less steel dip and slag, easy to disassemble and accommodate.

Mainly used for the use of conditions to the Sheng steel lining. More and more industrial raw materials are used in the melting pool and the bottom of the melting pool of the large double-end castings and the refining castings outside the furnace. The iron and steel industry is the foundation of the national economy and the important pillar of the social development.

The development of refractory materials industry of iron and steel industry depends on the improvement of technology, especially in recent years, the improvement of new heat insulation and refractory, ceramic fiber technology, for the use of new metallurgical technology to provide an inability to guarantee. Ceramic fibers cover 950℃ to 1600℃ low temperature industrial kilns, heating equipment and heat pipes, and become the scope of use of high efficiency and energy saving information. Ceramic fibers in the internal environment of the metallurgical industry used for 6 years into a row, as it is known to all, China is the world's largest steel country. However, in terms of short life, there is a difference between China and foreign countries, the key to extend the gap is to waste power, reduce consumption. Therefore, in the metallurgical industry, the National Economic and Trade Commission has entered the "total control, adjust the structure, improve the competitiveness and benefit of the company" development stage. Among them, the structure adjustment to further understand the "saving energy and reducing consumption, compact structure process, reduce the capital, improve the environment," the center of the guiding ideas of magnesia carbon brick with high melting point of alkaline oxide, magnesium oxide (melting point 2800 ℃) and difficult to be slag invasion of high melting point carbon and aluminum magnesium carbon brick materials as raw materials, all kinds of oxide additives. Non-charcoal composite refractory material combined with carbonaceous binder. Magnesia-carbon brick is mainly used for the inner lining of converter, AC arc furnace, DC arc furnace, slag line of ladle and so on.
