Magnesia-alumina spinel bricks have high durability, high temperature oxidation resistance and mechanical strength, and are widely used in various fields such as metallurgy, petrochemicals, and steel. With the development of science and technology and the improvement of industrial production levels, it is believed that magnesia-alumina spinel bricks will play their unique role in more fields.

1. Metallurgical industry
Magnesia-alumina spinel bricks have a small thermal expansion coefficient, high seismic resistance, compression resistance, tensile strength, and strong thermal shock resistance. They are widely used in the lining and furnace top of metallurgical equipment such as blast furnaces, converters, electric furnaces, and ladles, which can effectively improve the working life and stability of metallurgical equipment.
 
2. Petrochemical industry
Magnesia-alumina spinel bricks are often used as linings and thermal barrier layers for special chemical equipment such as reaction towers, riser pipes, refrigerators, and catalysts in the petroleum and chemical industries. They can maintain good performance in harsh environments such as high temperature, high pressure, and corrosion.
 
3. Iron and Steel Industry
Magnesium-aluminum spinel bricks are often used as lining materials in high-temperature sintering kilns, ladles, extension tanks and other equipment in steel enterprises. They have good thermal shock resistance and explosion-proof performance, and play an important role in improving the safety, stability and efficiency of steel production.
 
4. Other fields
Magnesium-aluminum spinel bricks are also widely used in kilns, boilers, glass kilns, rotary kilns, refractory materials and other fields, such as cement kilns and non-ferrous smelting industries. Magnesium-aluminum spinel bricks can work under harsh conditions such as high temperature, high pressure, corrosion, and mechanical wear, ensuring a highly stable working state, and therefore have broad market prospects.
