<p><P>PROBLEM TO BE SOLVED: To provide a method of deciding the rolling pass schedule of a steel plate and a method of manufacturing the steel plate, wherein the efficiency of production is improved. <P>SOLUTION: This method of deciding the rolling pass schedule of the steel plate and the method of manufacturing the steel plate have: a stage for setting a plurality of the number of temporary rolling passes of a group of materials to be rolled in a roughing mill; a stage for calculating stand-by time in the roughing mill; a stage for calculating the required time of the rolling in the roughing mill; a stage where the time required for transferring the material to be rolled from the roughing mill to a finishing mill is calculated taking the rolling finish time of the material to be rolled just before in the finishing mill into consideration and a stage for calculating the time required for the rolling in the finishing mill, wherein above each stage is performed to the all material to be rolled which is included the group of the materials to be rolled and, furthermore, these methods have a stage where the combination of the rolling passes in which the rolling time is shortest is selected as the rolling pass schedule after finishing the above each stage to the material to be rolled which is rolled lastly in the group of the materials to be rolled. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
