Primetals Technologies, in collaboration with Chugai Ro, a leader in the thermal technology field, and leading global electrification provider Hitachi, has received an order from Tokyo Steel, one of Japan’s leading steel producers, for the upgrade of a hot-dip galvanizing line at Tokyo Steel’s Okayama Works. The revamped line is scheduled to begin operations in the first quarter of 2027.
The project will utilize annealing equipment already in place at the Okayama site. Key improvements include the installation of induction heating (IH) technology in the front section to boost heating capacity, along with enhanced cooling capacity in the latter section. These updates will convert the line into a versatile production facility capable of manufacturing both cold-rolled and hot-dip galvanized coil.
Primetals Technologies is responsible for engineering and equipment supply for terminal equipment and skin pass mill modifications. Together with its partners Chugai Ro and Hitachi, the company will also handle engineering and supply of the annealing furnace equipment, along with supervision services for installation and commissioning.
