Product Details
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℃
