Refractory materials for aluminum electrolysis cells include silicon carbide castables, aluminum silicate castables, dry anti-seepage materials, lightweight castables, etc.

Aluminum melting furnace is a new type of aluminum melting furnace developed based on the aluminum melting process,During its use, when the temperature of the aluminum melt is 750 ℃, its viscosity is close to that of water at 20 ℃, making it highly susceptible to infiltration into the furnace lining and chemical reactions; When aluminum liquid comes into contact with refractory materials, SiO in the refractory materials₂、 TiO₂、 FeO and other oxides are easily reduced by aluminum, causing surface nodules, bulges, and precipitation of impurities on the furnace lining; During the operation of the furnace, the molten metal inside the furnace constantly churns and stirs, causing constant erosion and wear on the furnace lining. There is a risk of infiltration and cracking in the parts immersed in the aluminum liquid, and it can also cause peeling when the furnace is shut down. So the refractory material of the furnace lining in contact with the aluminum liquid must have high thermal stability and minimal impregnation, while also requiring high mechanical strength and hardness.

The casting material for aluminum electrolytic cells is a low porosity, high-strength high alumina refractory material and silicon carbide refractory material developed on the basis of traditional materials, which reduces the porosity of refractory materials, enhances their corrosion resistance and thermal shock resistance, improves the service life of materials, increases the service life of electrolytic furnaces, and adds economic benefits to aluminum plants. The anti-seepage castables, dry ramming materials, and high-strength wear-resistant castables produced by our company are mainly made of high alumina materials, and are formulated with active alumina powder, ultrafine powder, and anti-seepage agents.
