Refractory Ceramic Ball
1. Product Description
Refractory ceramic ball is made from industrial alumina and other rawrefractory materials, and processed by mixing, shaping and firing.It has properties of High strength and long working life; High chemical stability, and never react with the feeding materials; xcellent resistance to high temperature up to1900 °C.
Refractory ceramic ball 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 iniron and steel industries.
