High Alumina Refractory Ball

High temperature resistant performance

High mechanical strength, long use cycle

Good chemical stability, no chemical reaction with the material

Good thermal stability, high strength

  Description

Refractory ceramic balls are made of industrial alumina and refractory kaolin as the main raw materials, which are made by scientific formula, forming and hightemperature calcination.

 

Refractory porcelain ball is divided into ordinary refractory ball and high aluminum resistance ball. Refractory porcelain ball high temperature resistance to high temperature can reach 1900 degrees, high mechanical strength and long-term use.
