摘要： The object is to strictly eliminate the difference in offset of work rolls at the upper and lower and left and right of the rolling mill occurring in the kiss roll state before rolling or during rolling and eliminate the problem of warping of the flat products or meander or camber due to the thrust force acting between the work rolls and backup rolls.For this, there are provided a rolling mill for flat products having a pair of upper and lower work rolls driven by electric motors, a pair of upper and lower backup rolls, and devices for applying substantially horizontal direction external forces to barrels or shafts of the work rolls at positions of at least one location each at the work side and drive side, for the respective upper and lower work rolls, from the entrance side or exit side of the rolling mill, the external forces being supported through work roll chocks by project blocks of the rolling mill housing or work roll chock support members connected to backup roll chocks, and the value of the rolling direction offset of the work roll axial center position and backup roll axial center position divided by the sum of the work roll radius and backup roll radius being 0.0025 or less for both the upper and lower rolls, and a rolling method for flat products using the same.

摘要： The present invention discovers that a rolling direction force occurs even with conventional adjustment by the kiss roll state, pinpoints that the rolling direction force does not affect the roll thrust force, and thereby enables more precise initial roll gap position adjustment of a rolling mill (rolling zero adjustment).That is, this is based on the fact that high precision rolling zero adjustment becomes possible without being affected by any thrust force acting between rolls if performing differential asymmetrical roll gap zero point adjustment of the work side and the drive side so that the difference of the rolling direction forces acting on the roll chocks of the work side and the drive side of the work roll at the work side and the drive side (in practice, within ±5% of the sum of the rolling direction forces at the work side and the drive side).
