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°C.
Specially used in the high-low temperature shift furnace, converter, hydrogenation shift furnace, desulfurize furnace,etc.
Used in the hot wind furnace and heat up shift appliance in steel plant.
