摘要
The work rolls of the 6-high mill and by smaller diameter, rolling and hard steel than ever, and enables rolling at a higher reduction rate in the steel sheet of the same hardness, and as a cluster type multistage rolling mill So as not to cause a decrease in production by a small-diameter work roll mill use. In the cold rolling mill 51 minimum plate width is that in and maximum strip width of 600mm or more rolling a metal plate 1 of the following more than 1,500mm 1,900mm, and a pair of upper and lower work rolls 2 for rolling the rolling material 1, the work roll 2 a pair of upper and lower intermediate rolls 3, which respectively support, an intermediate roll 3 and a pair of upper and lower rolls 4 which respectively support, the axial shifting device 23 of the intermediate roll 3, the work rolls 2 and intermediate roll 3 of the bending devices 10 and 11 equipped with a door, the diameter of the work roll 2 and within the range of 300mm more than 400mm, and the diameter of the intermediate roll 3 I be within the range of 560mm or more 690mm.
