China 2021 Good Quality Silica Refractory Brick - High Quality High Refractory Alumina Ball – Rongsheng factory and manufacturers | Rongsheng Detail:

Alumina refractory balls have the fine quality of high strength, high hardness, excellent abrasion ability, thick bulk density, high temperature performance, corrosion resistance, less pollution and other excellent properties. alumina balls have been widely used in finishing and deep processing different types of ceramic, enamel, glass, chemicals and other thick and hard materials.

Properties of Alumina Refractory Balls

High Temperature Resistance
Good Heat Resistance
High Mechanical Strength
Long Service Life

Composition of Alumina Refractory Balls

Alumina refractory balls are made of AL2O3, kaolin, synthetic aggregate, mullite crystal and other materials. According to the rolling and the press molding method. aluminum refractory balls have the advantages of high strength, good thermal shock resistance, convenient replacement and cleaning, long service life and so on.

Alumina Refractory Balls Process

In order to make alumina refractory balls, the electrode is placed at the bottom of the graphite crucible, and the arc can be started by adding a certain amount of industrial alumina powder. Operating current 1.0kA, voltage 80~100V.After striking, as Al2O3 molten, loading gradually, until the material liquid filled with graphite crucible, the material liquid temperature is 2200 ~ 2300 ℃.After that, the crucible is poured out and the solution flows out.
