    Product introduction

    Refractory ball is made of industrial alumina and refractory kaolin as main raw material.It is with high mechanical strength, long service life; stable chemical properties;none chemical reaction with materials; It can endure high temperature resistance of max. around 1900 ℃. It is widely used in fertilizer plants to disperse gas and support, cover and protect catalyst. Refractory balls can also be used in hot blast furnaces and heating transformation equipment in the steel industry.
