SMS Demag to Provide Continuous Pickle Line for Tokyo Steel
05/28/2007 - Tokyo Steel has commissioned SMS Demag to supply a continuous pickling line, laser welding machine, and an acid regeneration plant for its works in Tahara.
Tokyo Steel Mfg. Co. Ltd., Japan, recently commissioned SMS Demag, Germany, with the supply of a continuous pickling line, laser welding machine, and an acid regeneration plant for its works in Tahara.
Tokyo Steel will use the new plant to pickle and oil 1.8 million tonnes/year of hot strip with widths of 780 to 1630 mm and with gages of 1.5 to 6 mm at a maximum process speed of 280 meters/minute. The pickling process will be implemented with heat recovery and acid regeneration equipment from a single source, thus achieving maximum efficiency at extremely low consumption values.
SMS Demag will supply the complete mechanical system, including the laser strip-welding machine and the acid regeneration plant. SMS Demag will also provide a double exit and a cross-cut shear in the exit section that will allow each coil to be divided without production losses.
Incorporating latest-generation turbulence-tank pickling technology, Tokyo Steel’s new acid regeneration plant will function according to the spray roaster process. The SMS Demag laser welding machine will include a strip butt-welding machine that welds together the strip ends by means of a laser beam. The modern entry design, which incorporates the strip butt-welding machine, enables high-quality, rollable weld seams to be produced, with minimal non-productive times in the entry section.
Commissioning of all facilities is scheduled for February 2010.
