Product Description
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.
