Ball also called refractory Regenerative ball is industrial alumina, the main raw material for the refractory clay calcination temperature form, it has:

1. Chemical stability, and do not react chemically with the materials.
2. The high mechanical strength, the use of a long life cycle.
3. High temperature performance, and the highest heat resistance temperature can reach 1, 700 degrees, is particularly applicable to the steel industry transform the hot stove and heating equipment. Reformer, pushing plate kiln scattered from the ball of gas-liquid and supporting role.
