Technology for Reducing Strip Meandering in Tandem

2020-3-6  Fig.10 shows the overview of the tandem cold mill at Kakogawa Works of Kobe Steel. The rolling mill comprises a total of 5 stands, and entry-side tension is imparted by the bridle rolls on the entry side of the mill. Tension-meter rolls for measuring the strip tension are disposed on the entry and exit sides of each stand and is controlled so that the tension value inputted beforehand in a table is imparted.
