Refractory ball usually used in shift converter and reformer in ammonia plant. Refractory ball has a lot of advantages, such as:
(1) High strength, long use period
(2) Chemical stability, it will not react with our materials
(3) Good performance of resistance high temperature, resistance high temperature up to 1900 C

Application:
(1) Specially used in the high-low temperature shift furnace, converter, hydrogenation shift furnace, desulfurization furnace, etc
(2) Used in the hot wind furnace and heat up shift appliance in steel plant.
