METHOD AND DEVICE FOR CONTROLLING COILING TEMPERATURE OF COIL IN HOT FINISH ROLLING

摘要

PROBLEM TO BE SOLVED: To improve yield by uniforming the material quality in the longitudinal directing after cooling and also stabilizing the control of coiling temperature.;SOLUTION: In accordance with the difference of cooling rate after coiling to the longitudinal direction of a coil, the target value in the control of the coiling temperature is consecutively changed in the longitudinal direction of the coil.;COPYRIGHT: (C)2001,JPO
