Title: Temper rolling method of steel sheet
Inventor: ENOKI HISANORI
IPC: B21B1/22
Filed: 2002-06-28
Abstract: <P>PROBLEM TO BE SOLVED: To provide a temper rolling method of a steel sheet by which mill stop is carried out or a weld zone is passed through a mill without generating scratches on a rolling roll.  <P>SOLUTION: In the temper rolling of the steel sheet, when stopping a temper rolling mill from the state where the temper rolling is carried out, the rolling rolls of the mill are opened after the deceleration of rolling speed is started and before the mill is stopped. When passing the weld zone of the steel sheet through the mill, the weld zone is passed through by preliminarily decelerating the rolling speed and opening the rolling rolls before the weld zone is passed through the mill in such a state where the rolling rolls of the mill are driven. After the weld zone of the steel sheet is passed through between the opened rolling rolls of the mill, the movement of the steel sheet in threading is stopped and, after closing the rolling rolls of the mill, the temper rolling is restarted.  <P>COPYRIGHT: (C)2004,JPO
