摘要： PURPOSE:To control the shape of a sheet material to be rolled to the target shape, and to impove the quality and yield of a rolled product, by operating plural shape correcting devices in accordance with a deviation signal between a shape detected signal of the sheet material and a target set value, in a multi cluster mill. CONSTITUTION:In a multi cluster mill equipped with a back up roll crown adjusting device, a work roll bending device, and an intermediate roll bending device; each function of the 1st order through 4th order is determined previously by putting, as a variable, a displacement quantity in the direction of sheet width, changing correspondingly to the malformation of a sheet material to be rolled, and a deviation signal, between a detected signal outputted from a shape detector of the sheet material and a target-shape set value, is expanded to an orthogonal function of the 4th order, and then, a shape-correcting device to be operated is selected, basing on each component value of the 1st order through 4th order corresponding to the shape of malformation, to correct the shape by a quantity corresponding to said component values with the aid of said correcting device, thereby a rolled sheet having excellent shape is manufactured in high yield.

摘要： PURPOSE:To obviate the generation of slips between rolls at a high speed and under high draft by limiting the equiv. roll surface roughness expessed by a specific equation of the work roll and driving intermediate rolls of a rolling mill. CONSTITUTION:The equiv. roll surface roughness given by the left side of the equation (Raw: the average roughness of the plate way of the surface of the roll 1, Ra1: the average roughness in the part equiv. to the plate way on the surface of the roll 2) of the rolls 1, and 2 is maintained at >=0.1mum in a method for rolling a plate material with a rolling mill provided with >=1 sets of roll clusters each consisting of the work rolls 1, driving intermediate rolls 2 and backup rolls 3, 4. Then the coefft. of friction between the rolls is maintained at a required value or above, and the slip between the rolls is prevented. Then no chattering in rolling is generated and the rolling at a high speed is made possible. The rolled plate material having excellent surface characteristics without any chatter mark is obtd.; further the rolling torque is transmitted with high efficiency from the rolls 2 to 1; therefore, high draft rolling is accomplished.

摘要： PURPOSE:To return a profile to a preset one by rotating an eccentric sleeve and to improve the shape controllability, by detecting a load of segmental back-up rolls at every supporting members, and computing an angle to be rotated for each eccentric sleeve. CONSTITUTION:When a roll profile comes to change by abrasion of bodies 14 of segmental back-up rolls, eccentric sleeves 15, and bearings 20 through longterm rolling, a motor rotating-angle arithmetic device 27 is actuated by an operator's manual input. Then, the device 27 computes a rotating angle of a motor 24 from the difference between a load value sent from a load cell 26 to be previously stored and a load value now being sent from the load cell 26 to output the result to a motor rotating-angle controlling device 29. Further, the device 27 judges which clutch 30 is to be connected and outputs it to a clutch controlling device 29. Then a roll profile formed by the segmental back-up rolls is returned to the initially set profile.

摘要： PURPOSE: To economically avoid an edge rupture by making a coefficient of friction between the surface of a rolling roll coming into contact with the side edge of a metallic plate and the metallic plate lower than that of the center part. CONSTITUTION: A metallic plate S is rolled by work rolls 1. For instance, the surface roughness Ra of a range A is set to 0.90μm, the surface roughness Ra of a range B to 0.45μm, and the width (e) of the side edge of a steel strip to 100mm. The enlargement of a crack does not occur on the steel strip cold- rolled in this way. That is, a rolling is performed after making a coefficient of friction between the side edge of a width of 5 to 300mm including the edge of the metallic plate S and the surface of a rolling roll 1 coming into contact with this side edge lower than a coefficient of friction in the center part except the side edge. Rolling mill lubricant more than that of the center part is supplied on the side edge. Also, the rolling mill lubricant with a concentration higher than that of the center part is supplied to the side edge. Consequently, the productivity of the rolling can be improved.
