摘要： The invention relates to a device for processing a metal slab, plate or strip, comprising a rolling mill stand with a roll nip between two driveable rolls, the rolling mill stand being designed to roll a metal slab, plate or strip between the rolls. According to a first aspect of the invention, the device is provided with feed means which are designed to guide the slab, plate or strip between the rolls at an angle of between 5° and 45° with respect to the perpendicular to the plane through the center axes of the rolls. According to a second aspect of the invention, the device is provided with one or more following rolling mill stands with driveable rolls, and the rolling mill stand and one or more following rolling mil stands are designed in such a manner that, during use, their rolls have different peripheral velocities, the difference in peripheral velocity amounting to at least 5% and at most 100%.

摘要： The invention relates to a method for processing a steel product, in which the steel product is passed between a set of rotating rolls of a rolling mill stand in order to roll the steel product. According to the invention, the rolls of the rolling mill stand have different peripheral velocities such that one roll is a faster moving roll and the other roll is a slower moving roll, and the peripheral velocity of the faster moving roll is at least 5% higher and at most 100% higher than that of the slower moving roll, and the thickness of the steel product is reduced by at most 15% per pass, and the rolling takes place at a maximum temperature of 1350°C. The invention also relates to a steel product produced using the method, and to the use of this steel product.

摘要： The invention relates to a method for processing a continuously cast metal slab or strip, in which the slab or strip is passed between a set of rotating rolls of a rolling mill stand in order to roll the slab or strip. According to the invention, the rolls of the rolling mill stand have different peripheral velocities, and the difference in peripheral velocity is at least 5% and at most 100%, and the thickness of the slab or strip is reduced by at most 15% for each pass. The invention also relates to metal plate or strip produced using this method.
