Toyo Kohan Taps Primetals Technologies for Pickling Line Upgrade
12/16/2025 - Japanese steel producer Toyo Kohan has tapped Primetals Technologies to modernize the pickling line at its Kudamatsu plant.
Primetals Technologies said the project includes upgrading coil handling with new entry-side transport equipment, replacing the pickling tanks with polypropylene tanks and installing a laser welding machine (LBW).
Entry-side equipment automates coil transport from the coil yard to the process line for improved handling efficiency. Polypropylene tanks eliminate the need for multimaterial tank structures, simplifying maintenance.
The companies said the LBW can process steel sheets up to 9 mm thick using laser cutting and welding. This takes away reaction forces and allows for easier maintenance since the blade doesn’t have to be replaced, and clearance adjustments don’t have to be made.
The companies said they expect the project to be completed in 2028.
