摘要： An embodiment of the present invention provides a rolling roll which is improved to provide a greater rolling reduction under a limited capacity of a rolling mill and to enable the penetration of deformation to the center of the thickness of a material to be rolled irrespective of the width change of the material to be rolled, and a rolling system comprising the rolling roll. The rolling roll according to an aspect of the present invention has a structure in which the diameter thereof varies from the roll side to a barrel, the rolling roll comprising: a first pressurization part formed at the center of the barrel so as to be in contact with the center of the material to be rolled; a second pressurization part which forms a first inclined curved surface on both sides of the first pressurization part, has a diameter continuously reduced to be smaller than that of the first pressurization part, and has a stepped portion; and a third pressurization part which forms a second inclined curved surface on both sides of the second pressurization part, has a diameter continuously reduced to be smaller than that of the second pressurization part up to the edge of the barrel, and has a stepped portion.

摘要： A method for manufacturing an ultra-thin sheet steel comprising the steps of roughly rolling a steel billet into a sheet bar, but joining the sheet bar so rolled to a preceding sheet bar, heating widthwise edge portions of the sheet bars so joined by means of edge heaters, continuously cross rolling joined bars by means of paired cross rolls at least at three stands for finishing to produce a hot rolled steel strip having a sheet width of 950 mm or greater, a sheet thickness of 0.5-2 mm and a crown of ± 40 νm or less, cold rolling, continuously annealing and temper rolling the hot rolled steel strip, and plating the surface of a cold rolled steel strip as required to produce a sheet steel having an average sheet thickness of 0.20 mm or less, a sheet width of 950 mm or greater, and a sheet thickness variation in a sheet width direction of ± 4 % of the average sheet thickness and a hardness (HR30T) variation in the sheet width direction of ± 3 or less of the average hardness in a range not less than 95 % of a sheet width.

摘要： In a tandem mill system, at least one first type rolling mill is arranged in the upstream side and at least one second type rolling mill is arranged in the downstream side. The first type rolling mill is of the so-called work roll crossing mill in which a pair of work rolls are inclined with respect to a pair of back-up rolls supporting the work rolls and simultaneously crossed each other in a horizontal plane to control transverse thickness distribution of a strip. The second type rolling mill is of the so-called HC mill which controls the strip crown and shape by a combination of axial movement of intermediate rolls and work roll bending. Such an arrangement makes it possible to increase a capability of controlling the strip crown and shape, particularly, a capability of correcting the quarter buckle, and eliminate a fear of causing scratches on the strip and roll surfaces, with the result of improved production efficiency. Plural lines of lubricant supply device are also provided to stop supply of a lubricant immediately before biting of the strip into the work roll crossing mill and start the supply again after the biting. A system of lubricating the work roll crossing mill is thereby improved.
摘要翻译：在串联轧机系统中，至少一个第一类型的轧机设置在上游侧，并且至少一个第二类轧机设置在下游侧。第一类轧机是所谓的工作轧辊交叉轧机，其中一对工作辊相对于支撑工作辊的一对支承辊倾斜，同时在水平面上彼此交叉以控制横向条的厚度分布。第二种轧机是所谓的HC轧机，它通过中间轧辊的轴向运动和工作辊的弯曲来组合控制带材的顶部和形状。这样的布置使得可以增加控制带材凸厚和形状的能力，特别是修正四分之一带扣的能力，并且消除了在带材和辊表面上产生划痕的担心，结果提高了生产效率。还提供多条润滑剂供应装置，以便在将条带咬入工作辊交叉磨机之前立即停止供应润滑剂，并在咬合之后再次开始供应。从而提高了工作辊交叉磨机的润滑系统。

摘要： In a tandem rolling mill facility and a rolling method using the tandem rolling mill facility, stable rolling is performed with suppressing deflection of working rolls 1 and without fluctuation of working roll bearing boxes 4. Axes of working rolls 1 are offset toward a side opposite to a side of larger tension between tensions acting on a rolled material 10 at an inlet side and an outlet side with respect to axes of intermediate rolls 2, and a hydraulic cylinder 11 for pushing a working roll bearing box 4 toward the same side as the offset direction is contained in a block 8.
