摘要： PROBLEM TO BE SOLVED: To provide a method of predicting deformation resistance of a metal strip by which the deformation resistance of a material to be rolled with a cold tandem mill is predicted with high accuracy and simply and a method of correcting the setup of a cold tandem mill using the predicted deformation resistance. SOLUTION: By measuring shearing load at the same time when shearing a metal strip coil after hot rolling or the metal strip coil after hot-rolling to pickling before cold tandem rolling over the whole sheet width, the deformation resistance of the metal strip is determined from sheet thickness, sheet width and shearing load. Corrected setup load is determined by the determined deformation resistance and the preset value of each rolling stand is corrected on the basis of this corrected setup load.

摘要： PROBLEM TO BE SOLVED: To provide a plate rolling method capable of suppressing the variation of offset amount of work rolls in the upper and lower parts and the right and left sides (work side, drive side) and preventing a material to be rolled from causing an unstable phenomenon such as warpage, meandering and camber. SOLUTION: Before the material 6 to be rolled is bitten with the work rolls 1a, 1b, roll bending force which is not less than the set value of the bending force necessary to obtain at least one of target plate crown and plate shape or a predetermined prescribed times of the set value is previously imparted to the work rolls 1a, 1b by a roll bending force imparting mechanism 5. Then a restricting force in the vertical direction is imparted to work roll bearings 1a, 1b, thereby suppressing the variation of the offset of the work rolls caused by impact load when the material 6 to be rolled is bitten with the work rolls 1a, 1b.
