摘要： PURPOSE:To assure the passing characteristic of a strip and to prevent the snaking and drawing of the strip adequately by disposing a hearth roll which permits changing of the temp. distributions in the roll and free changing of the rate of crown in a continuous annealing furnace. CONSTITUTION:A central cavity part 12 and both end cavity parts 13, 13a are formed in a circumferential direction within the barrel part 11 of a hearth roll body 10 which is internally hollow. The barrel part is expanded to provide an adequate rate of crown by putting fluid in these and controlling the respective fluid temps. To this end, fluid circulating circuits 14, 15, 15a communicating with the respective cavity parts and coolers 16, heaters 17 and bypasses 16a, 17a for these are provided to the respective circuits. The circulating fluid is passed through the coolers 16 or the heaters 17 according to need so that the temp. distributions in the rolls are changed. When the generation of the snaking in excess of the set value is detected with detectors for the rates of snaking in proper places in the furnace, the rate of crown is controlled with a roll crown controller 20 so that the desired rate is obtained.

摘要： PURPOSE:To better the shape of the end of rolled stock by constituting one of a pair of bracing rolls of an arbor position of which is adjustable around axial line and provided with spiral steps on both ends of its large diameter part and a bracing roll sleeve freely rotatable on the outer periphery of the large diameter part. CONSTITUTION:An arbor 13 is rotated through a worm 17 and a worm wheel 18 by driving an electric motor 16 and the length L just above the upper work roll 1 is made to coincide with W of a rolled stock S. Rolling force is applied to the roll 1 through an upper bracing roll 6 by an pressing device, and when necessary, an increase bending device or decrease bending devices 10, 11 are used. Lubricating oil is sent to a clearance 23 by a hydraulic pump through oil grooves 20, 21. The upper and lower work rolls 1, 3 are driven and rolling of the rolled stock S is started. Then, an upper bracing roll sleeve 14 is rotated around the outer periphery of large diameter part of fixed arbor 13 by the roll 1, and a lower bracing roll is rotated by the roll 3. Thus, a rolled stock having good end shape is obtained.
摘要翻译：目的：通过构成一对轴承位置的一对支撑辊之一来改善轧制端部的形状，该支撑辊可以围绕轴线调节并且在其大直径部分的两端上设置有螺旋台阶和支撑辊套筒可在大直径部分的外周自由转动。构成：通过驱动电动机16使心轴13通过蜗杆17和蜗轮18旋转，使正好在上部工作辊1上方的长度L与轧制坯料S的W重合。将轧制力施加到辊1通过加压装置通过上支撑辊6，并且当需要时，使用增加弯曲装置或减小弯曲装置10,11。润滑油通过液压泵通过油槽20,21输送到间隙23中。上下工作辊1,3被驱动，轧制坯料S的滚动开始。然后，通过辊1使上支撑辊套14围绕固定心轴13的大直径部分的外周旋转，并且下支撑辊由辊3旋转。因此，获得具有良好端部形状的轧制坯料。

摘要： PURPOSE:To improve shape control ability for a steel plate and to improve flatness by installing at least respectively one unit of a sleeve diameter expanding type rolling mill on the upper stream side of a continuous rolling mill and a sleeve slide type rolling mill on the down stream side. CONSTITUTION:At least one of a sleeve sliding type rolling mill A of which the sleeve 3 is made freely movable in an axial direction and an intermediate backup roll shift type rolling mill B of which the intermediate backup roll 10 is made freely movable in an axial direction is disposed to the lower stream side stand of a continuous rolling mill. A shape control function is provided without changing rolls as against the change in the plate width of the down stream side stand. At least one of a sleeve diameter expanding type rolling mill C of which the sleeve 13 is made freely swellable in a radial direction by a pressure medium is installed to the upper stream side stand, whereby shape correcting ability is improved, responsiveness is improved and the crown edge drop of the plate is reduced.
