摘要： PROBLEM TO BE SOLVED: To improve the quality of products, yield of products and production efficiency and to reduce the cost of equipment such as the cost of construction and cost of equipment maintenance as compared to a slab casting-large reduction rolling method. SOLUTION: After a 20-50 mm thick sheet bar which is continuously cast with a sheet-bar caster 1A is passed through a 1st posture straightening device 7A as it is and made into an upend sheet-bar coil SC1 by coiling the sheet bar in a upend state, the upend sheetbar coil is uncoiled and, after the sheet bar is passed through the 2nd posture straightening device 1B and finish rolling is executed, it is coiled into a hot coil SC2.

摘要： PURPOSE:To improve the consumption unit of roll and to prevent the lowering of operating efficiency by detecting the number of revolutions of a work roll and the load of bearings and releasing the hydraulic valve of a rolling reduction device when the number of revolutions and its lowering rate reach the prescribed conditions. CONSTITUTION:The number of revolutions N of a work roll 1 is detected by a pulse generator 12 connected to a mill motor 11. A rolling load F is detected by a load cell 13 placed at the upper part of a mill housing. A hydraulic servovalve 9 is released; when a continued time of revolution, at the condition that the number of revolutions N is kept at N

摘要： PURPOSE:To prevent the mutual interference of a machine and optimize the start timing of automatic position control of the machine by holding the machine where there is no mutual interference caused and controlling the start timing of the automatic position control. CONSTITUTION:A computor 4 calculates a mechanical position suitable for a rolled material and outputs a roll gap and position references 8 of a work roll and an intermediate roll shift to a controller 8. The controller 8 performs the processing of an APC timing control part 16 at settable timing. The APC control part 17 starts respective APC at timing specified by the timing control part 16 and outputs optimum speed references 9, 10, 18, and 19 to respective mechanism control sytems 6, 7, 14, and 15 so that deviations between the position reference 8 and position feedback values 11, 12, 20, and 21 from the respective mechanism control systems 6, 7, 14, and 15 are within a target permissible error range.

摘要： PURPOSE:To automate zero adjusting operation and to improve controllability for shapes by operating the rotating angles of eccentric rolls provided to split backup rolls from the differences between the flatness of a plate after rolling and reference values and changing said angles by means of servocontrol mechanisms. CONSTITUTION:In multistage cluster rolling mills, first a reference material to be rolled is rolled, and the detected values of a detector 26 for plate shapes are stored as reference values in an arithmetic device 27 for zero adjustment. The device 27 is operated after the start of prescribed rolling to calculate the rotating angles of motors 24 from the differences between the detected values of the detector 26 and the stored reference values, and the signals thereof are outputted to a controller 28 for rotating angles of motors. The device 27 judges of clutches 30 to be connected and outputs to a controller 29 for clutches. When prescribed clutches 30 are connected, the motors 24 are rotated by prescribed rotating angles by the respective outputs of the controller 28, a detector 25 for rotating angles, and the device 27. As a result, the angles of eccentric sleeves 15 of the split backup rolls are changed and the prescribed profiles of the rolls are restored.

摘要： PURPOSE:To compensate the fluctuations in the thickness on the outlet side of rolling stands and to obtain a material to be rolled of uniform thikness without changing the peripheral speeds of rolls by forecasting said fluctuations from the fluctuations in the tension on the inlet and outlet sides of the rolling stands and correcting the screw down positions of the rolls. CONSTITUTION:The fluctuations in tension are detected or forecast with a tension detector 40 disposed between a final stage rolling stand 12n and an upper stream side stand 12n-1 thereof. The output of the detector 40 is inputted to an inlet side tension-thickness compensator 62, which forecasts the fluctuations in the thickness on the outlet side of the stand 12n and applies a correction signal to an automatic thickness controller 34. The output signal of the controller 34 is applied to a screw down position controller 36, which corrects the screw down position of a roll 16n. At this time, the rotating speed of a roll driving motor 14n-1 is compensated with a screw down compensation controller 48, whereby the change in the height of louvre is prevented.
