Description

Features Specifications: refractory balls Product: refractory balls (ceramic material) size: 0.****0mm Refractory ceramic balls are made from industrial alumina and other raw refractory materials, and processed by mixing, shaping and firing. It has many properties: 1.High strength and long working life; 2.High chemical stability and never react with the feeding materials; ***** resistance to high temperature up to ***0 degree. Applications: Refractory ceramic balls can be used as support and covering packing for catalyst in shift converter, reformer , hydro converter and can also be used as packing in hot blast heater and heat transformer in iron and steel industries.
