Reasons for the decline of high alumina brick performance

Jan. 01, 1970

High alumina brick is now used more common refractory brick, mainly with high aluminum material and other high alumina content of raw materials composition.

High alumina brick has high thermal stability, high strength and good slag resistance. The main reason for the decline of high alumina brick is:

1, high aluminum powder and high alumina aggregate mix uneven.

2, material humidity and sequence and time.

3, forming pressure for the resulting volume density, strength is not enough.

4, the distance between brick and brick gap dense, causing uneven temperature.

We supply a variety of refractories, such as high alumina brick, ceramic fiber board, sic heating element etc. Welcome to contact us.
