The manufacture of hot-rolled strips 0.8-1.5 mm in thickness as a final product of metallurgical works necessitates strict requirements for gage interference of the strip, namely, with a tolerance of ±5%. The tension variation for such a range of rolled products significantly affects the gage interference. Consideration is given to corrected algorithms for calculation of the torque of an electric drive for a loop lifter and the definition of the angle of the loop-lifter ascent and the control algorithm for the loop size in the interstand area, which are realized in a digital automatic system for the tension and loop control in a 2500 wide-strip hot-rolling mill. The pilot study proved that the implementation of advanced algorithms and the developed system for interactive tension and thickness control made it possible to meet the increased gage interference requirements.
