Alumina Refractory Balls
Alumina refractory balls are a new kind of high temperature heat insulation material, alumina balls is made by smelting and blowing of industrial alumina in electric furnace. Use aluminum balls as the main body, can be made into various shapes, the highest temperature 1800 ℃, high mechanical strength, general light products several times, and the bulk density is only half of the corundum products.
Alumina Refractory Balls Description
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
1.High Temperature Resistance
2.Good Heat Resistance
3.High Mechanical Strength
4.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.
