To transform 3 mm cold strip entry coils into ultrathin strips of stainless steel, the mill would require an automation system and drives that delivered precise torque control. Nidec’s advanced technologies and automation capabilities made it possible for the mill to achieve these exacting standards.
Nidec engineered and installed the Level 1 automation and Level 2 platform needed to operate and control the stainless steel-making process, including speed and tension control, sequencing and systems logics. The solution included main and auxiliary motors and drives, sensors, instrumentation and communication systems. In addition to project engineering and system erection, Nidec also provided a safety system adhering to the strictest European regulations that protect steel workers who interact with the automated
The new rolling mill is designed to operate at a maximum speed of 800 m/minute, producing as much as 52,000 tons of thin and ultrathin stainless-steel coils per year.
