40MM 50MM 60MM Low Creep Refractory Ball Manufacture
Brief Introduction:
This kind of refractory ball is our patented product. We developed the ball by introducing nanometer technology, increasing wind temperature more than 1250°. The service life is as long as one campaign of blast furnace. It can be used second time and energy saving is excellent. At present it is the first choice in the field of ball-type hot stove.
Features:
1. Excellent energy saving
2. High mechanical strength
3. High chemical stability
4. Good circulation usage
