Product Description

Refractory Brick OEM Quality Magnesia Alumina Spinel Brick for Reaction Chambers and Stoves

Magnesia Alumina Spinel Brick is a high-performance refractory material, mainly composed of magnesium-aluminum spinel (MgAl₂O₄), with excellent thermal shock resistance, high temperature resistance and erosion resistance. This brick is widely used in the lining of high-temperature industrial furnaces such as steel, glass, cement, etc., especially in high-temperature and high-erosion environments.
Main features:
High heat resistance: The refractoriness of magnesia alumina spinel brick is usually above 1900°C, and they can operate stably for a long time in high-temperature environments.
Excellent thermal shock resistance: Spinel structure materials can maintain structural integrity and reduce cracking or peeling when experiencing rapid heating or cooling.
Erosion resistance: Magnesia alumina spinel brick have strong resistance to chemical erosion by slag, alkaline and acidic
materials, and are particularly suitable for use in highly corrosive environments.
High compressive strength: This brick still maintains high mechanical strength in high-temperature environments and can withstand pressure from the furnace structure.
Environmental protection: Due to the relatively environmentally friendly composition of the material, magnesia alumina spinel brick are not easy to produce harmful byproducts or toxic gases, which meets modern environmental protection requirements.

Main raw materials and production processes:

Raw materials: Magnesium oxide (MgO) and aluminum oxide (Al₂O₃) are the main raw materials for magnesia alumina spinel brick. Magnesium-alumina spinel is produced by high-temperature sintering or electric melting.
Production process: Magnesium oxide and aluminum oxide are sintered at high temperatures to form refractory bricks with a spinel structure. Depending on the specific application, other materials can also be added to improve its corrosion resistance, strength or thermal conductivity.

Refractory Brick OEM Quality Magnesia Alumina Spinel Brick for Reaction Chambers and Stoves
Steel industry: used for the lining of steel making converters, electric furnaces, refining furnaces (such as AOD furnaces, VOD furnaces), ladles and tundishes, which can effectively resist the erosion of high-temperature molten steel and slag.
Cement industry: Magnesia alumina spinel brick are widely used in the firing zone and transition zone of cement rotary kilns, especially in areas with severe high temperature and chemical erosion.
Glass industry: used for the lining of glass melting furnaces, which can resist the erosion and high-temperature oxidation of molten glass.
Non-ferrous metal smelting: can be used for smelting furnaces and other high-temperature furnace equipment for non-ferrous metals such as aluminum and copper.
