<P>PROBLEM TO BE SOLVED: To provide a flying plate thickness changing method and apparatus, by which a plate thickness changing part before and after a weld point is shortened and the setting of roll speed and the setting of a roll gap for suppressing tension variation are performable in a flying plate thickness changing rolling. <P>SOLUTION: In the flying plate thickness changing method by which the plate thickness before and after a joined part are rolled into a finished thickness which is different from the plate thickness in stationary parts when a preceding material and a succeeding material are jointed and continuously rolled with a tandem mill, a plate thickness changing point 1 from the stationary part to a plate thickness changing part and a plate thickness changing point 2 from the plate thickness changing part to the stationary part are included together between the uppermost-stream rolling stand and to downmost-stream rolling stand, but are not included together between the same rolling stands. <P>COPYRIGHT: (C)2013,JPO&INPIT |
