WINDING TEMPERATURE CONTROLLER

摘要

PROBLEM TO BE SOLVED: To provide a winding temperature controller with which the pattern of the quantity of cooling water for a rolled stock is prevented from being affected by disturbance, by on-line deciding the quantity of cooling water in consideration of a variation in speed of the rolling stock and a variation in temperature on the inlet side of a cooling system.

SOLUTION: In the winding temperature controller for controlling the temperature of the rolling stock before a winding reel to the target value by cooling the rolling stock rolled with a hot-rolling mill with a plurality of cooling banks installed on the outlet side of the hot-rolling mill, a means for respectively calculating initial cooling length for every cooling unit of a material on the basis of a temperature model and a setting calculation information of the hot-rolling mill by taking a cut-length sheet virtually dividing the rolling stock in the advancing direction of the rolling stock as a material cooling unit and a means for correcting the initial cooling length by relating it to the deviation of a detected temperature to the temperature by the setting calculation of the rolling stock on the outlet side of the hot-rolling mill and the deviation of detected average speed to the average speed by the setting calculation of the rolling mill are provided.
