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 wont react with our materials

3) Good performance of resistance high temperature, resistance high temperatue up to 1900 degree C.
