摘要： A rolling mill comprises a pair of crown work rolls each having, at both ends of a drum, tapered ends ground at different taper angles, respectively. The work rolls are located one above the other with one tapered end of one work roll being in opposition to one tapered end having a different taper angle of the other work roll. The work rolls are movable in axial directions, such that edges of the plates are rolled by one tapered end of one work roll and a drum of the other work roll, and between tapered ends of both the work rolls. The method and rolling mills are capable of controlling the crown and edge drop reduction and simultaneously preventing local protrusions such as high spots and edge built-up to produce flat rolled plates having no difference in thickness and further capable of controlling the crown and the edge drop according to the material, thickness and width of the plates.
摘要翻译：一种轧机包括一对冠工作辊，它们在滚筒的两端分别具有不同锥角的锥形端部。工作辊彼此重叠，一个工作辊的一个锥形端与另一个工作辊具有不同锥角的一个锥形端相对。工作辊可沿轴向移动，使得板的边缘由一个工作辊的一个锥形端部和另一个工作辊的滚筒以及两个工作辊的锥形端部之间滚动。该方法和轧机能够控制冠部和边缘下落减少，同时防止诸如高点和边缘组合的局部突起以产生没有厚度差异的平坦轧制板，并且还能够控制冠部和边缘部分根据材料，板的厚度和宽度。

摘要： A sheet crown control method and apparatus for use in endless rolling in which consecutively fed sheets are joined to each other to be continuously rolled through a rolling equipment line. The rolling equipment line includes a junction device for joining consecutively fed sheets to each other, a plurality of stands arranged in tandem on the downstream side of the junction device and having a roll bender load adjusting mechanism and a roll crossing mechanism. The roll cross angle of rolls incorporated in a stand of each rolling mill is set at a predetermined value beforehand if there is a roll cross angle that will enable a target sheet crown to be applied to each sheet and the roll bender load of each stand is adjusted on-line, thereby effecting sheet crown control. Rolling also may be performed while adjusting the roll cross angle of rolls incorporated in stands of each rolling mill on-line together with the roll bender load. The roll bender load and the roll cross load may be adjusted in a transition region where a junction between sheets exists or in a stationary region where sheets of the same material follow one after another.

摘要： A method of continuously hot-rolling sheet bars in which a roughly rolled leading sheet bar and a trailing sheet bar are abutted prior to a hot finish rolling step. Plastic deformation of either or both of the cut rear and front end portions of the leading and trailing sheet bars is applied. End portions are brought into contact with each other due to metal flow, forming a gap portion between the sheet bars. The thickness of the sheet bar around the gap portion is enlarged in comparison to the thickness of the contact portions, and hot finish rolling fills the gap so that the bars are strongly joined over their width.

摘要： In this invention, a back end portion of a preceding sheet bar and a front end of a succeeding sheet bar are cut in a transfer line at an entrance side of a finish rolling mill so that at least both side edge regions of these sheet bars are contacted with each other at a butted contact state thereof and a gap is formed between both end portions and then portions to be joined int he preceding and succeeding sheet bars are locally heated and pushed to join them while gradually enlarging a joining area, whereby the required time is largely reduced as compared with the conventional technique and also it is attempted to miniaturize the heating apparatus and shorten the length of the apparatus.
