Features of Alumina bubble bricks :
1. Electric arc furnace: Electric arc furnaces used in steel manufacturing, these furnaces need high temperature tolerance and good insulation performance when operating.
2. Glass melting furnace: Bauxite foam bricks are often used in glass production to insulate and protect furnaces to improve energy efficiency and reduce heat loss.
3. Ceramic kilns: Used for firing high-temperature ceramics, they can effectively insulate and reduce heat loss.
4. Non-ferrous metal melting furnaces: Such as aluminum melting furnaces, these furnaces need to maintain high temperatures and avoid heat loss.
5. High-temperature reactors in the petrochemical and fertilizer industries: These equipment also often use bauxite foam bricks to achieve good thermal insulation.
