Abstract

PURPOSE:To control the shape of the rolled material, by shifting the rolling lines of upper and lower work rolls to the sides opposite to the draft line of upper and lower backup rolls, and by installing the horizontal bending device for the work roll on the shifted side. CONSTITUTION:In respect of the draft line made by connecting the centers of the upper and lower backup rolls 3, 4, the upper work roll 1 is shifted to the upstream side and the lower work roll 2 is shifted to the downstream side. During the rolling work by this rolling mill, the upper and lower work rolls 1, 2 cause the distortion so as to escape toward the shifted side. For controlling the sheet shape by utilizing this distortion of the work roll, the push rolls 6 are installed for pushing the outer surfaces of upper and lower work rolls 1, 2, on the shifted side of the rolling line, in order to adjust the horizontal distortion; these push rolls 6 are supported by the backup rolls 7. Then, the tansfer device 10 is operated for adjusting the pushing force of the push roll 6 through the backup roll 7, and the displacement of the pushing force is transformed into the vertical displacement, and the distortion of upper and lower work rolls 1, 2, is freely adjusted along their longitudes.
