摘要： PURPOSE:To manufacture stably a steel sheet having a uniform sheet thickness by housing each roll chock of upper and lower rolls in a main housing of a multisage multipass rolling mill and housing each roll chock of intermediate rolls in a subhousing supported by the main housing. CONSTITUTION:In case of rolling a steel sheet 1 by a multistage multipass mill consisting of upper and lower rolls 2, 3 and intermediate rolls 4, 4; a roll chock 5 of the upper roll 2 is supported by a main housing 10 through a rolling-reduction screw 7, and a chock 6 of the lower roll 3 is supported by the housing 10 through a hydraulic cylinder 9, and a balancing cylinder 11 is interposed between both chocks 5, 6. Each of roll chocks 12, 13 of the upper and lower intermediate rolls 4, 4 is also supported by a subhousing 16 through a rolling-reduction screw 14 and a hydraulic cylinder 15. The subhousing 16 is fixed to the main housing 10 through connecting members 17, 18. Because each of the chocks 5, 6, 12, 13 is directly supported at its upper and lower parts by the rolling-reduction screw and the hydraulic cylinder, the sheet position is not deviated even when a rolling force fluctuates, and a steel sheet of uniform sheet thickness is stably manufactured.

摘要： PURPOSE:To make the pass characteristic of plate stable and make control effective by determining the maximum value of plate crown control amount based on shape blind zone and distributing the control amount within that range thereby performing the plate crown control. CONSTITUTION:In rolling, the deformation resistances obtained from the width, thickness, steel kinds, temperature, etc. necessary for determining shape absolute blind zone are sent to a setter 9 by the signal from a rolling condition operating setter 8. From these values, the blind zone is operated by an arithmetic unit 10. Next, from this value, the maximum value of plate crown control amount is determined and within this range the control amount is distributed to the double chock work roll bending devices 7 of the respective stands. In this case, the degree of permissible shape is larger as it goes toward the upper stream stands and therefore the practicable blind zone may be widened and the plate crown control amount in the upstream stands may be correspondingly increased.

摘要： PURPOSE:To control plate-crown correctly and constantly, by installing a plate- crown-detecting means and a plate-shape-detecting means on the outlet side of the final stand of a continuous rolling unit, and by the feedback of the output signal of the plate-shape-detecting means to the final stand. CONSTITUTION:A material to be rolled is rolled by a series of stands from the first stand S1 to the final stand S6, and the plate crown of the product is measured by a plate-crown-detecting means 15 installed on the outlet side of the final stand S6. The measured value is inputted to an arithmetic unit 17, and is fed back to roll- bending unit 7 of the stands excepting the stand S6. That is, the detected value of plate crown is changed to a bending press. signal by the unit 17, and compared with the reference value of bending press. of each stand. When the detected value of plate crown is different from the reference value, the bending press. of each unit 7 is controlled for the correction. The plate shape on the outlet side of the stand S6 is detected 16, and the detected value is inputted to an arithmetic unit 19, then fed back to the unit 7 of the stand S6, i.e., when the plate shape is detected 16, the output signal is inputted to the unit 19, where the signal is converted to bending press.

摘要： PURPOSE:To make obtainable the sheet of good shape, by detecting the sheet shape and profile on the delivery side of the stand being subhected to the double chock bending, by respectively processing the detected values, and by utilizing them for controlling the inside and outside benders. CONSTITUTION:The shape of the rolled sheet 5 on the delivery side of the rolling mill constituting of work rolls 1, 2, and upper and lower backup rolls 3, 4, being subjected to the double chock bendings FIW, FOW, and FIB, FOB, is detected by the detector 9 through the TV-camera 7; and the sheet thickness is detected by the profile detector 10 through the X-ray thickness meter 8. The signal processing circuit 11 receives outputs of above two detectors, and judges the shape of edge wave and center buckle from the shape of the sheet 5, and operates the controlled variables for the outside benders FOW, FOB, and besides, operates the controlled variables for the inside benders FIW, FIB, from the thickness of the sheet 5; hereby, the benders are controlled respectively through the hydraulic pressure converters 19-22. In this method, since the bending is controlled at the position to be free from the shape change despite the profile change, the sheet of good shape can be obtained.

摘要： PURPOSE:To hold the control amounts of the fore stage and expand the control amount of the final stand by cooperatively controlling the plural stands of the fore stage as group and letting plate crowns be controlled within shape blind zones independently of the stands of the post stage. CONSTITUTION:In the respective stands S4-S6 of the post stage, the control amounts of the plate crown of the respective stands S4-S6 are forecast and operated in an arithmetic unit 12 with the widths b1-b6 of the shape blind zone in each stand as data and the plate crowns are independently controlled within the individual shape blind zones in the respective stands by controlling pressure regulating valves 10 with respective pressure indicators 11. Here, the allowable range of the shapes is widened except in the final stand S6 and the plate crowns are controlled at the large plate crown control amounts within the practicable blind zones. In the final stand S6, the plate crown control is accomplished within the shape absolute blind zone. Thereby, the plate crown control amount in the final stand may be expanded.

摘要： PURPOSE:To control the sheet crown without worsening the sheet shape, by installing the roll bending device in the stand except the final stand so as to be the sheet crown controlling stand, and by inputting the detected sheet crown value on the delivery side of the final stand to above stated roll bending device as the feedback. CONSTITUTION:When the sheet crown detector 14 on the delivery side of final stand S6 detects the sheet crown of the product, the output signal is inputted to the signal processor 10 which converts the input signal into the bending pressure to control the sheet crown. In the processor 10, the set value of the bending pressure is determined so as to obtain the aim final sheet crown in consideration of the shape blind sector; therefore, the actually measured value is compared with the aim crown value depending on the signal produced from the detector 14. If these two values are different, the set value of the bending pressure is corrected by using the detected sheet crown value, and the final sheet crown value is controlled to the aim sheet crown value. According to this method, the passability of the sheet is stabilized, and the improvement of the yield and quality can be contrived.
