Hopewind researched and developed HD2000 Engineering-type Frequency Converter, which has always been running stably since being put into operation on the high-speed wire rod main rolling mill of Lingyuan Iron&Steel Co., Ltd. It indicates that the product fully meets the performance requirements of metallurgical rolling mill and reaches the level of the international first-class brand in technology.

Generally speaking, the rolling line production process in the iron and steel industry has high requirements on the control accuracy of frequency converter. Furthermore, the load of the rolling mill equipment changes rapidly and has a large impact, with  high requirements on the frequency converter response and overload performance. Continuous production line also requires high reliability of frequency converter equipment, so the frequency converter of the main rolling mill has aways been monopolized by a few foreign first-line brands for a long time.
