Magnesia-alumina bricks have a refractory limit of more than 1700°, good resistance to rapid cooling and heat resistance, and can resist the erosion of basic slag. They are used for laying the roof of basic open hearth furnaces and electric furnaces in steelmaking.
Magnesia alumina brick is a refractory material mainly composed of magnesia (MgO) and alumina (Al2O3). It has good high temperature performance, corrosion resistance and thermal shock performance, and is often used in various high temperature equipment. Regarding the application of magnesia-alumina bricks in electric furnaces, the following is a detailed introduction:
[Application of magnesia-alumina bricks in electric furnaces]
1. Electric furnace wall lining: Magnesia-alumina bricks can be used as wall lining materials for electric furnaces, including electric arc furnaces, induction furnaces, and resistance furnaces. Its high temperature stability and corrosion resistance make it ideal for withstanding high temperature environments and chemical attack.
2. Insulation layer: In addition to being used as a wall lining material, magnesia-alumina bricks can also be used for the insulation layer of electric furnaces. Due to the low thermal conductivity of magnesia-alumina bricks, it can effectively reduce heat loss and improve the thermal efficiency of the electric furnace.
3. Melting furnace: Magnesia-alumina bricks are also suitable for some special electric furnaces, such as aluminum electrolytic cells and magnesium electrolytic cells. In these smelting furnaces, magnesia-alumina bricks are able to withstand high temperatures and chemical corrosion, and provide good refractory properties.
Although magnesia-alumina bricks have many advantages in electric furnaces, it is still necessary to consider specific conditions when selecting refractory materials, such as working conditions and processing substances. Different types of electric furnaces may require different refractory materials, so it is best to consult professionals to determine whether it is suitable to use magnesia-alumina bricks or other refractory materials according to actual needs.
