摘要： PURPOSE: To prevent the variation in breadth of a coil, by applying an edging process to a strip with one or plural couples of vertical rolling mills, between a crop shear installed on the run-out side of a roughing mill train and a final finishing mill.
CONSTITUTION: Between a crop shear 9 and a horizontal rolling mill 11, or if possible, between two horizontal rolling mills 11 on the down-stream side in a finishing mill train 10, one or plural edging mills 12, respectively comprising one or plural vertical rolls, are arranged. Before a strip, running out of a roughing mill train 6 and passing through the crop shear 9, is finished into a product coil by the finishing mill train 10, the strip is subjected to an edging process operated by the said edging mill 12. The strip is, following to this edging process, subjected to a thickness reducing rolling pass operated by the horizontal rolling mill 11; hereby, the variation in breadth of the coil is remarkably reduced to a smaller value as compared with a value obtained by a conventional method.

摘要翻译：目的：为了防止线圈宽度的变化，可以通过在一台或多台立式轧机上对带钢进行边缘加工，将其安装在粗轧机列车的出口侧的作物剪切与最后的精加工磨。构造：在作物剪切9和水平轧机11之间，或者如果可能的话，在精轧机10的下游侧的两个卧式轧机11之间，分别包括一个或多个垂直轧制机卷，安排。在粗轧机列车6运行并通过作物剪切机9之前，通过精轧机10将其完成成产品线圈，该带材经受由所述磨边机12操作的磨边加工。在该边缘化处理之后，经过由水平轧机11操作的厚度减小轧制通道; 因此，与通过常规方法获得的值相比，线圈的宽度的变化显着地减小到较小的值。

摘要： PURPOSE:To make the control action for the rolling work for the thin sheet stable and free from the time lag, by forecasting the timing of the start and the end of the unsteady rolling work, by utilizing this forecasted timing signal for operating the rolling reduction and the controlled variable for the shape, and by changing these outputs in connection with the output of the controlled variable. CONSTITUTION:When the material 30 to be rolled is inserted into the payoff reel 28, the arithmetic control 23 is actuated to operate the rolling reduction, the biting speed, and the maximum rolling speed, of each of rolling stands 1-5; these outputs are inputted to the control circuits 6- 10. The arithmetic control 23 outputs these various data and acceleration to the forecasting circuit 24 which thereupon operates the time of duration of the unsteady rolling state from the biting speed to the maximum rolling speed. The output of the forecasting circuit 24 is inputted to the arithmetic circuit 25 which thereupon operates the control factor for the rolling reduction at the period of speed-up which is changed according to the length of duration of the unsteady rolling work, and the control factor for the shape at the period of speed-up; the outputs of the circuit 25 are inputted to the controlled variable outputting circuit 26. At the same time as the biting of the material 30 to be rolled is started, the controlled variable output circuit 26 starts the control for the shape of the rolled material to a proper range and continues this control over all period from the biting till the dropout of the tail end of the rolled product.

摘要： PURPOSE:To reduce the amount of crop, by preliminarily reducing the volume of a crop-forming part of the slab to be rolled. CONSTITUTION:A slab, to be obtained by the continuous casting work or by the blooming work, is formed into a parallelepiped shaped in which top and bottom ends of the slab are tilted toward the rolling direction by a specified angle theta from the normal against the front and back surface of the slab. The volume of the unsteadily deforming zone at the top and bottom ends of the slab, that is the crop- forming part, is limited within a range about twice thickness of the slab in the rolling direction, so that the amount of crop to be formed at top and bottom ends of the slab is greatly reduced by forming the slab into abovementioned shape.

摘要： PURPOSE:To reduce the width fluctuations of the material to be rolled in the rough rolling process by installing the rolling mill incorporated with the rolls having annular protrusions in the hot rough rolling mill row and controlling the openings of the rolls according to the width fluctuations of the material to be rolled. CONSTITUTION:The material to be rolled such as slab having been heated in a heating furance 1 is sent to a finishing mill row 6 by way of a rough vertical rolling mill 3 and rough horizontal rolling mill 4. The rolling mill incorporated with the rolls having annular protrusions is disposed on the upstream side excluding the final stand of the rough rolling mill row. Horizontal screw-down and vertical screw-down schedules are transmitted from the upstream side and are stored in a rough rolling pass schedule operating memory device 8. In a plate width detecting unit 7, the width of the material to be rolled 2 in the fore-stage stand is detected and the detection signal thereof is sent together with the signal of the device 8 to a roll opening correction amount calculating device 9. The roll opening correction amount calculated in the device 9 is transmitted to a roll opening control unit 10 and the roll opening is controlled by the unit 10 according to the width of the material to be rolled 2.

摘要： PURPOSE:To increase the spread, by giving overall reduction using the horizontal or vertical roll, before giving a partial reduction using the partially reducing type horizontal roll. CONSTITUTION:The partially reducing type horizontal roll has two ring type protuberances whose diameter is D, breadth is W, height from the drum surface is H, and interval between midst of both ring type protuberances is (l); this partially reducing type horizontal roll is used together with another horizontal roll with flat drum. For the purpose of comparison, the rolling is carried out by above partially reducing type horizontal roll independently, without using the horizontal roll of the same size installed nearby the upper stream of the partially reducing type horizontal roll. The result of this comparison is shown in the correlation graph for the rolling reduction and the spread in the partially reducing type horizontal roll. In the graph, the black round mark shows the case of independent partially reducing type horizontal roll, and the white round mark shows the case of the roll by this invention. The graph indicates that the spread of the slab obtained by the roll of this invention is extremely larger than that obtained by an independent partially reducing type horizontal roll.

摘要： PURPOSE:To greatly increase the alterability of breadth of the salb, by installing a couple of horizontal rolls and a couple of specially shaped, combined work rolls on the upstream side of the hot roughing mill. CONSTITUTION:A slab 5 is heated to described temperatures by the heating furnace 4, and is fed to a couple of combined work rolls 11 provided with a box caliber and one or more annular projections. The box caliber of this combined work roll 11 is assigned to the edging work for the slab 5, and the annular projections are assigned to the broadside rolling work. Required number of passes of said edging work and broadside rolling work is respectively applied to the slab 5 in a reverse rolling method. Then, the slab 5 is rolled by the horizontal rolls 10 through a required number of passes, and following to it, the slab 5 is passed through the hot roughing mill 6, the crap shear 7 and the hot finishing mill 8 in this order, and is coiled by the coiler 9.

摘要： PURPOSE:To prevent camber formation by hot-cutting a slab with a pair of V- shaped blades after forming the slab in dog bone-shape by edge-rolling prior to the hot-cutting. CONSTITUTION:The both ends of a rectangular slab 1 are edge-rolled by edging rolls 4 in a form similar to the form 1b of the slab after cutting thus forming the slab in dog bone-shape 1a. When the dog bone-shaped slab is cut by a pair of V- shaped blades 2, the cut ends expand so that the slab is cut into symmetric pieces 1b thus preventing cambering in the successive process.
