Detailed description
Refractory ceramic balls
(1)Product Descriptiom
Refractory ceramic balls are made from industrial alumina and other raw refractory materials, and
processed by mixing, shaping and firing. it has properties of
1.High strength and long working life,electrical insulation;
2.High chemical stability,and never react with the feeding materials;
3.Excellent resistance to high temperature up to 1900℃.
Refractory ceramic balls can be used as support and covering packings for catalyst in shift converter,
reformer, hydro converter, desulfurizer, and methanator, and can also be used as packings in hot blast heater
and heat transformer in iron and steel industries.
