<p><P>PROBLEM TO BE SOLVED: To roll a material to be rolled into a desired thickness without breaking the material when performing rolling while supplying a lubricant between a roll and the material to be rolled during rolling in hot rolling. <P>SOLUTION: When hot-rolling a metallic sheet, the thickness of the metallic sheet (material to be rolled) 8 on the inlet side of a rolling mill (F7) is continuously determined by calculation from the measured thickness of the metallic sheet (the material to be rolled) on the outlet side of the rolling mill (F7), the measured speed of the metallic sheet (material to be rolled) on the inlet side of the rolling mill (F7) and the measured speed of the metallic sheet (material to be rolled) on the outlet side of the rolling mill (F7) and the gap between the upper and lower rolls of the rolling mill (F7) is continuously adjusted by taking the thickness of the metallic sheet (material to be rolled) on the inlet side of the rolling mill (F7) as input and aiming that the thickness of the metallic sheet (material to be rolled) on the outlet side of the rolling mill (F7) is the desired value. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
