摘要： PURPOSE:To rapidly remove local defects in flatness and to obtain a product having good flatness by controlling injection from coolant nozzle headers based on flatness detection results in plural roll coolant control regions segmented in the width direction of a strip. CONSTITUTION:A 1st coolant injection deciding means 31 and a 2nd coolant injection deciding means 32 are installed in the output side of a flatness deviation computing element 24. The element 24 calculates a deviation value of an actual detected flatness value found by a shape detector 22 from a previously decided target value. The deviation value is converted into a flatness deviation value corresponding to zone segmentation of coolant nozzle headers 20. The 1st means 31 processes the flatness deviation value to output a 1st coolant flag. Also, the 2nd means 32 processes the deviation value to output a 2nd coolant flag. Both the flags are inputted to a 3rd coolant injection deciding means 33 to output a coolant open-and-close signal for each coolant injection solenoid valve 21 decided as a logical sum.

摘要： PURPOSE:To permit control of the width drop to be generated at the front and rear ends of a sheet bar with good accuracy by determining the contact length between the parallel parts of dies and slab so as to minimize the width deviation of the cross rolling reduction at the longitudinal ends of a rolling stock predicted from specific conditions. CONSTITUTION:The position at the front end of the slab 3 conveyed by table rollers 4 is measured by a measuring roll 5 turning in contact with the front surface of the slab 3, a length measuring instrument 6 mounted thereto and a slab front end detector 7. The result of the measurement is inputted to a controller 8. On the other band, the shape (thickness, width) and cross rolling reduction of the slab 3 are preliminarily inputted to the controller 8. The temp. of the slab 3 is measured on the inlet side of a press by a themometer 9 and the result of the measurement is transmitted to the controller 8. The optimum length of the parallel parts of the dies and the slab is calculated from the specific conditions including the slab thickness, slab width, slab temp. and the cross rolling reduction by the press. The position of a table driving motor 10 is controlled in accordance with the result of the calculation.

摘要： PURPOSE:To prevent flawing of a slab surface by a slip between table rollers and the slab by detecting the retreating and advancing speeds of the slab during the cross rolling by a press and synchronizing the speeds of the table rollers with the retreating and advancing speeds of the slab. CONSTITUTION:Rollers 7, 8 for detecting an inlet or outlet side speed rotate and the roller revolutions are converted to pulses by pulse oscillators 9, 10 when the retreat or advance arises in the slab 1. The pulse signals are inputted to arithmetic units 11, 12 for inlet and outlet side table speeds, by which the table speeds are calculated. The calculated speeds are transmitted to control units 13, 14 for inlet and outlet side table speeds, by which the speeds of the inlet and outlet side tables 5, 6 are controlled and are synchronized with the retreat and advance speeds of the slab. While the speed detecting rolls are used in the above, the detection of the speed by means for measuring the position changes at the front and rear ends of the slab by distances using pinch rolls 2, 3 or ultrasonic waves or laser beams is also possible.

摘要： PURPOSE: To improve working efficiency by measuring the delivery speed of a material to be rolled or a material to be straightened on the outlet side of a rolling mill or a straightening machine and executing feed-back or setup of the measured value to the number of revolution of the rolling mill or the straightening machine and the number of revolution of a table roller. CONSTITUTION: The speed of the steel material 6 to be straightened delivered from the straightening machine 7 is measured with a speedometer 4 provided on the outlet side of the straightening machine 7. The measured value is inputted to a computer 5 and, based on the measured delivery speed, the exact number of revolution of a straightening roll 8 and the numbers of revolution of the table roller 1 on the inlet side and table roller 3 on the outlet side are calculated using an equation stored in the computer 5. Those calculated results are set up before the next steel material gets on the table roller 1 on the inlet side and straightening is executed by those values. In this way, rolling or straightening work is smoothly at the delivery speed as set and working efficiency is improved.
