Abstract

PURPOSE: To control elongation percentage highly accurately and excellent in responsiveness by controlling a peripheral speed of one bridle roll by a 1st speed control means and controlling a peripheral speed of the other bridle roll by outputs of a speed setter and an elongation percentage setter.
CONSTITUTION: A deviation of a tension imposing on a rolled stock 1 being between a rolling mill 2 and a bridle roll 6 and being detected by a tension detector 29 from a reference value is calculated by an adder 27. A peripheral speed correction amount of a rolling roll is found by a tension controller 26 so that the above deviation is brought to be zero. The sum of the correction amount and a speed reference value calculated by a rolling mill speed reference computing element 25 is found by an adder 24 and the sum is used as a corrected speed reference value. A rolling mill 2 is controlled by a speed controller 12 based on the reference value through a motor 7. A deviation of a tension imposing on the stock 1 being between a bridle roll 5 and the mill 2 and being detected by a tension detector 28 from the reference value is calculated by an adder 32 and a draft correction amount bringing the draft correction amount to be zero is found by a tension controller 31 to control a roll gap by a draft controller 17.
