Advantages
The advantage:
- High wear-resistance.
- The rollers can be ground for 3-5times
- The roller has the large diameter ,large weight and high density
The bebefit:
High roller capacity
Once complete new roller can manufacture about 16000--18000ton tube ,the rollers can be ground for 3-5times, the roller after grinding can manufacture additional 8000-10000 ton tube.
The total tube throughput manufactured by one complete roller set: 68000 ton
