Product Detail

High Alumina Refractory Ball Product Description

 

Refractory high alumina 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 alumina 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.

 

High Alumina Refractory Ball Features

 

1. high temperature resistant performance, the highest heat resistant ceramic ball temperature can reach 1900 degrees;

2. high mechanical strength, long use cycle;

3. good chemical stability, no chemical reaction with the material;

4. good thermal stability, high strength;
