摘要： Provided is a method of controlling operation of a tandem rolling mill which enables large reduction rolling in the latter-stage stand of the tandem rolling mill necessary for manufacturing fine-grained steel, and so on. The method comprises: a step of determining a first exit-side sheet thickness in rolling a constant portion of a material to be rolled; and a step of determining a second exit-side sheet thickness in rolling a front end portion of the material, such that a pre-tightening load becomes a set value or less; the material is rolled into the second exit-side sheet thickness, until the front end portion is fed into the stands; the constant portion is rolled by the stand given a pre-tightening load into the first exit-side sheet thickness; and the second exit-side sheet thicknesses of the stands given the pre-tightening load are made larger than the first exit-side sheet thickness.
摘要翻译：提供一种控制串联式轧机的操作的方法，其能够在制造细晶钢所需的串列式轧机的后级机架中进行大的压下等。该方法包括：确定第一出口侧片材厚度滚动待轧制材料的恒定部分的步骤; 以及确定在材料的前端部分滚动的第二出口侧片材厚度的步骤，使得预紧负载变为设定值或更小; 将材料卷入第二出口侧片材厚度，直到前端部分被供给到支架中; 所述恒定部分通过预紧力负载被所述支架轧制到所述第一出口侧板材厚度中; 并且使得具有预紧力负载的支架的第二出口侧片材厚度大于第一出口侧片材厚度。

摘要： Provided is a manufacturing apparatus and manufacturing method of hot-rolled steel sheet which enables uniform cooling of a rolled material and improvement of the surface properties thereof. The manufacturing apparatus comprises: a rolling stand; a supplying device capable of supplying lubricant to work rolls and/or backup rolls; an online roll grinding device; and a removing device capable of removing at least part of the lubricant before the surface of the work rolls is ground by the grinding device. The manufacturing method comprises the steps of: removing at least part of the lubricant adhered to the work rolls, or to the work rolls and backup rolls using the lubricant removing device after completing rolling of a preceding material; grinding the work rolls using the online roll grinding device after the removing step; and supplying the lubricant to the work rolls and/or backup rolls from the lubricant supplying device.
摘要翻译：提供一种能够均匀地冷却轧制材料并提高其表面性能的热轧钢板的制造装置和制造方法。制造装置包括：轧制机架; 能够向工作辊和/或支承辊供给润滑剂的供给装置; 在线辊磨机; 以及能够在通过研磨装置研磨工作辊的表面之前能够去除至少一部分润滑剂的除去装置。该制造方法包括以下步骤：在完成轧制前面的材料之后，使用所述润滑剂去除装置去除附着在所述工作辊上的至少一部分润滑剂，或者移除所述工作辊和所述支承辊; 在拆卸步骤后使用在线滚动研磨装置研磨工作辊; 并将润滑剂从润滑剂供给装置供给到工作辊和/或支承辊。
