Rolling thin to drive green
The thinner the strip, the more efficient the electrical equipment. The challenge for steelmakers is to roll the strip down to minimum thickness without breaking it while maintaining surface quality and flatness.
Unique achievement in cold rolling
Fives has set a record in silicon steel cold rolling. The DMS 20Hi EcoMill, a proprietary technology developed for cold rolling, enables a strip to be rolled down to 0.1mm on the full width of 1,250 mm, which represents a unique achievement in the industry.
The new rolling mill was supplied to Xinyu, part of China’s Baowu Group, and is capable of producing 100,000 metric tons of high-quality NGO grades at a rolling speed of 800m/min. These steel grades are mainly dedicated to high- performance electrical motors requiring high-quality silicon steel.
