摘要： PURPOSE:To remove th restriction of product thickness and to save energy consumption by installing a delay table, having a heating device and three controllers, between a roughing mill and a crop shear, and actuating the controllers, used for transporting the latter half of divided materials, to perform selection controls. CONSTITUTION:Both of the inlet-side temperature FET of a finishing mill 5 and the outlet-side temperature FDT thereof estimated basing on a pass schedule, are required to be included in the allowable range of a target temperature FDT*. A comparison device 17 compares the FDT with the FDT*, to introduce a material to the mill 5 after lowering its transporting speed by a block 21 when the FDT is included in the allowable range. When the FDT is out of the allowable range, recalculation is performed by a block 19. After comparing the FDT* with the FDT by a comparison block 18, the material placed at the stand-by position is fed to the mill 5 by an output block 22 when the FDT is higher than the FDT*, and the material is introduced to the mill 5 by heating it by a heating device 10 when the FDT is lower. By this selection control, the consumption of heat energy can be saved.

摘要： PURPOSE:To greatly improve the torque loss detecting accuracy, and to improve the rolled material's front tension detecting accuracy, by treating the torque loss as the function of the rolling load additionally to the rotational speed, when the tension is obtained from the rolling load, the armature current of the motor, the magnetic flux and the rotational speed of the rolling mill. CONSTITUTION:The signal for each of the back tension Tb of the rolled material 3 fed into the rolling mill 1 to be detected by the detector 4, the rolling load F, and the armature current I, the magnetic flux phi, the rotational speed N, of the motor 2, is inputted to the front tension detector 5. In general, the torque loss consists of the motor's iron loss, the windage loss and the rolling mill's reduction gear loss and bearing friction loss. The electric current loss and torque loss arithmetic units 10, and 11, 12, operate the losses, and the subtractors 13, 8a, 8b, subtract these losses. The multiplier 7 operates the torque to be generated by the motor, and this value is treated by above stated subtraction; hereby, the rolling torque G is obtained. From this rolling torque G, the rolling load F, and the back tension Tb, the tension arithmetic unit 9 operates the front tension Tf.

摘要： PURPOSE:To rationalize operation by transporting the latter half material cut by crop shear at a prescribed retardation speed without once stopping the transport ation before introducing the material to a finishing mill by accelerating it to the inlet-side speed of the mill again. CONSTITUTION:In performing the designed dividing rolling of a rolling material by installing a delay table and a crop shear between a roughing mill and a finishing mill, the transportation of material is controlled, so that the latter half of material is transported by retarding it to a prescribed retardation transporting speed without once stopping the transportation before introducing it to the finishing mill by accelerating its speed to the inlet-side speed of finishing mill. Further, the retardation transporting speed is decided, by estimating the transporting loci of the tail end of the former half material and the front end of the latter half material in the process of the finishing mill and succeeding ones and calculating so that the gap time of the leading stand of finishing mill is minimum. In this way, the material transportation is performed by bringing the latter half material closer to the preceding material till the allowable limit of the restriction in installation.

摘要： PURPOSE:To let the width control of high accuracy be effected by setting the rough rolling mill edger roll opening in each edgering pass by considering the dog bone part width return amount of the rolling material. CONSTITUTION:In each edging pass, correct edger roll openings are calculated by using the respective parameters of the simple width spreading amount of the rolling material with rough rolling mill horizontal rolls, the various specifications of the finishing rolling mills and the respective edgering pass weight components of the rough rolling mill exit side target width determined from the exit side target plate width thereof and the dog bone part width return amount of the rolling material by the abovementioned rough rolling mill horizontal rolls, and based on these calculated values, the edger roll openings are set. According to this method, the more precise plate width controlling as compared to before may be done.

摘要： PURPOSE:To minimize the transitional turbulence in the material balance, by selecting the speed pattern in order to make the rolling speed of each stand, being changed at every time that the size changing point of the material arrives at arbitrary rolling stand, to satisfy the specified condition. CONSTITUTION:When the size changing point of the material arrives at the rolling stand No.1 and this fact is detected, the draft position controller 10a is controlled by the rolling schedule setting arithmetic unit 1, in order to change the draft position of the stand No. 1. Next, if the arrival of the size changing point of the material at the stand No. 2 is detected, the draft position of the stand No. 2 is changed by the controller 10b. At the same time, the rolling speed as the speed command for each rolling stand is respectively inputted to the rolling speed controller 11a...11e from the principal speed controlling arithmetic unit 2. The rolling speed pattern for each of the rolling stands No. 1-No. 5 is selected so as to always minimize the total amount of alteration of the rolling speed due to the change of size. According to this method, the stability of operation and the rolling efficiency are improved.

摘要： PURPOSE:To provide the titled device preventing the generation of telescope by monitoring continuously with on-line the position of a coil end face which changes every moment during the winding of a strip as a coil and by controlling the entering angle of the strip to a coiler mandrel based on the deviation signal thereof. CONSTITUTION:When a strip S is wound round a mandrel shaft 1 via a table roller 8, the position (l) of a coil end face is detected by a end face sensor 36. On the other hand the coiling signal of the strip S is shown as a signal C of a timer of a timing control circuit 46 by the signal of a sensor 35B of behind a pinch roll 7 which detects the existance thereof and the initial position signal l0 of the end face is stored into a memory l0 of a memory device 37 with closing of a contact 43 by the signal C thereof. Simultaneously an operation 44 is performed on a telescope amount DELTAl=l-l0 and also a contact D is closed and an end face shape controlling is started. A positioning device 39 feeds back a signal of the position of the shaft 1 transmitted by a shifting position detecting device 42 and moves at high speed the shaft 1 by DELTAX' with the driving of a hydraulic cylinder 41 and controls in zero the telescope amount which is at the turn of the outest periphery of the coil 2.

摘要： PURPOSE:To improve the shape of coils and the workability in coiling work in the stage of coiling hot strips on coilers by detecting the tension of the strip between finishing mills and pinch rolls and controlling said tension so that the same attains prescribed value. CONSTITUTION:When a strips arrive S at a final finishing stand F7, backward tension Tb is operated with a backward tension operating device 18. When the preceding end of the strip S arrives at a detector 25, a coefft. (a) of torque arm is operated and is stored. In this state, the speed command value of the speed controller 6 for pinch rolls 4 is applied with a predicted synchronizing speed command value by using the output from a speed detector 10 for the stand F7. When the preceding end of the strip S advances further and arrives at a detector 26, tension is detected and operated by an operating device 20. Tension control is started with a controller 22 and the tension between the stand F7 and the rolls 4 is controlled so as to attain prescribed value at all times, whereby the collapsion of the coiled shape is prevented and coiling work is performed more effciently.
