Refractory ball in industrial alumina and refractory kaolin as the main raw material, scientific formula, shaped and made ​​of high-temperature calcination, Fire resistance ceramic ball has high mechanical strength and long using period, and refractory ball have good chemical stability and it connot have chemical reaction with materals, It has excellent high tempreature resistance and the highest heat-resistant tempreature can reach as high as 1900 °C. They are widely used in petrolem chemical ,fertilizer ,natural gas and environmental protection industry. With stable chemical features and a low rate of water absorption,they can resist high temperatures and high pressure,and also can resist the corrosion of acid,alkali and some other organic solvents,and can stand the change in temperature during the application.Ceramic balls can increase the distribution spots of gas or liquid, and to support and protect the activating catalyst with low strength.

Refractory ball usually used in shift converter and reformer in ammonia plant. Refractory ball has a lot of advantages, such as:
● High strength, long use period
● Chemical stability, it won’t react with our materials
● Good performance of resistance high temperature, resistance high temperature up to 1900℃

Refractory ball application
● Specially used in the high-low temperature shift furnace, converter, hydrogenation shift furnace, desulfurization furnace, etc
● Used in the hot wind furnace and heat up shift appliance in steel plant.
