Introduction
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 temperatue up to 1900℃
