PROBLEM TO BE SOLVED: To provide a simultaneous rolling method of a plurality of deformed steel plates capable of enhancing the productivity by simultaneously rolling two deformed steel plates. SOLUTION: The simultaneous rolling method comprises steps of: of selecting a first and a second deformed steel plates common in the thickness of at least ends thereof and the material characteristic out of a plurality of candidate deformed steel plates to be rolled; preparing a rolling schedule for a simultaneously plural deformed steel plates in which the first and second deformed steel plates selected in the deformed steel plate selection step are connected to each other at a common thickness part and rolled, and the steel plate profiles of the first and second deformed steel plates are included; rolling a simultaneously deformed plural steel plates for performing the simultaneously deformed plural steel plates rolling schedule; cutting a large steel plate obtained by the simultaneous plural deformed steel plates rolling step, and dividing the large plate into small ones including the steel plate profiles of the first and second deformed steel plate; refining of finishing the small plates obtained by the division step into the first and second deformed steel plates. These steps are successively performed. COPYRIGHT: (C)2007,JPO&INPIT |
