#Corundum_brick is a refractory material with α-alumina (Al₂O₃) as the main component. It has very high refractoriness, good thermal shock resistance and chemical stability, so it is widely used in high-temperature industries. Here are some detailed introductions to the main uses and characteristics of corundum bricks:
Uses of Corundum brick
1. Steel industry: used for lining of blast furnaces, converters, electric furnaces and other equipment to protect the equipment from erosion by high-temperature molten metal.
2. Glass manufacturing: as a refractory material for melting pools, chutes, material channels and other parts to ensure temperature control and product quality during glass melting.
3. Petrochemical industry: used for lining of high-temperature equipment such as cracking furnaces and heating furnaces to prevent high-temperature corrosion.
4. Ceramic industry: used for the construction of kilns to increase the service life of kilns.
5. Other high-temperature working environments: such as cement rotary kilns, non-ferrous metal smelting furnaces, etc.
Features Corundum brick
1. High refractoriness: The refractoriness of corundum bricks can reach above 1770℃, which is suitable for extremely high temperature working environments.
2. Good thermal shock resistance: Even in the case of rapid heating or cooling, it can maintain the integrity of the structure and reduce damage caused by thermal stress.
3. Excellent wear resistance: It has good resistance to the wear of solid particles and prolongs the service life.
4. Good chemical stability: It has good resistance to most acid and alkali solutions and is not easy to react chemically with slag.
5. Low thermal conductivity: It helps to reduce heat loss and improve energy efficiency.
6. High density: It usually has a higher volume density, which helps to improve its mechanical strength and wear resistance
