<p>PROBLEM TO BE SOLVED: To obtain a rolled product with good rolling accuracy and good finishing temperature accuracy even when the thickness of final product is set thin in continuous hot rolling line. SOLUTION: In the temperature control method of finishing mill to control the temperatureθof rolled stock 11 out of a finishing mill 15 at a target temperatureθR in a continuous hot rolling line which rolls rolling stock 11 transferred from a roughing mill 12 into a prescribed thickness by the finishing mill 15, an induction heater 13 to heat the rolling stock 11 transferred from the roughing mill 12 is arranged near the inlet of the finishing mill 15, the temperatureθis measured at the outlet of the finishing mill 15 for the rolling stock 11, and then supplied power U for the induction heater 13 is feed-back controlled so that this temperatureθbecomes the target temperatureθR.</p> |
