摘要： PURPOSE:To detect exactly generation of snaking in an initial state and to prevent surely and easily the snaking by preventing the uneven elongation of a rolled material having a correlation with the shifting rate of a plate owing to snaking. CONSTITUTION:The asymmetrical component DELTAlambda(=lambdaW-lambdaD; lambdaW, lambda are the difference in elongation rate between operating and driving sides) relative to the center of the width of a plate of a difference in the elongation rate of a rolled a material 1 is detected with a shape detector 3 and is outputted to a discriminator 6. Control is required when DELTAlambdanot equal to 0 and the plate shifts to the driving side if DELTAlambda>0 and to the operating side if DELTAlambda

摘要： PURPOSE:To control properly the sheet shape and sheet crown of a steel strip by inputting the detecting values of a crown meter and a shape meter located respectively at the exit of a rolling mill to a feedback control device and correcting a bending force of each stand, in rolling the strip by a tandem finishing mill. CONSTITUTION:In rolling a steel strip 4 by a six-stage tandem finishing mill, the sheet crown and sheet shape of the strip 4 are detected by a crown meter 8 and a shape meter 9 arranged respectively at the exit of the mill, to input the detected results to a feedback control device 7. The device 7 outputs an additional signal, basing on these sheet crown and sheet shape, to the bending-correcting output of a predictive control device 6 which houses a model equation for predicting the thermal crown of a roll with the passage of time, to perform a feedback control. The rolling material 4 is rolled by correcting the deviation of a bending force by the work roll of each stage, to obtain a sheet material having prescribed sheet shape and sheet crown at the exit.

摘要： PURPOSE:To enable the rolled product with high thickness accuracy to be always obtained, by inputting information in respect of the steel grade and specifications other than thickness signal of the thickness detector, to the X-ray monitoring controller, and by inputting the output of its operation to the automatic thickness controller. CONSTITUTION:The output of the thickness detector 5 for the thickness of steel material 2 after the hot rolling pass, and the change-over output of the X-ray monitoring change-over device 10, like as the change-over switch for example, for the steel grade, specifications, etc., are inputted to the X-ray monitoring controller 9. The output of the controller 9 is inputted to the automatic thickness controller 6; hereupon, the output of the controller 9 to be inputted to the controller 6 is obtained by processing so as to control the roll gap of work rolls of the rolling mill 1 to obtain the optimum biting thickness, taking the thickness at the point of time of detecting by the device 5 as the reference. By the present method, since the X-ray monitoring control, possible to obtain the constant thickness for every steel material 2, can be performed even if the steel grade is altered, the thickness control can be performed regardless of the steel grade or specifications.

摘要： PURPOSE:To calculate the aim temperature depending on the actually resulted data and various items of rolling condition, and to improve the accuracy of temperature, by inputting the altered aim coiling temperature for the hot rolled strip to the coiling temperature computer being on-line. CONSTITUTION:When the alteration of coiling temperature of the hot rolled metallic strip is desired, the operator selects the temperature variation (b) turning the knob 2 of the rotary switch. Hereby, the variation (b) is converted to the electric signal and is inputted to the coiling temperature control unit CPU(C) through the signal feeder 5. Next, various items of rolling condition (d), aim temperature (d'), actually resulted data E, etc., are inputted to CPU(C) through the linkage with another computer D. According to these input values, CPU(C) newly calculates the aim coiling temperature, and inputs the result C to the cooler F. Further, CPU(C) corrects the error of coiling temperature depending on the input (f) from the cooler F and actually resulted data (e), etc.

摘要： PURPOSE:To change the set point of the draft and rotation of the hot finishing mill in order to contrive the improvement of the rolling efficiency, by permitting the operator to set the variation of the draft of the final stand and the rotation frequency factor of each stand of the finishing mill group, in case of altering the lot according to the judgement of the operator. CONSTITUTION:When the higher rank computer 3 causes the trouble by some reason, the operator selects the system utilizing the microcomputer 6, by operating the selective relay 1. Then the operator sets the draft variation X6 of the final stand in the digital switch 7, sets the reflection X6' against the rotation in the digital switch 8, and sets the rotation frequency factor (hi) of each stand of the finishing mill group in the digital switch 9; and at the same time, the operator inputs these data to the microcomputer 6 by operating the relay 2. Hereby, the microcomputer 6 operates the draft variation of each stand and the rotation frequency of the lot material after these variations, and produces the output to each of the draft motor 4 and the rotation motor 5, in order to execute the alternation of the lot.

摘要： PURPOSE:To make possible the passage of a stable tail part through the preset volume operation alone, by providing a deceleration rate setter to each stand of rolling mills. CONSTITUTION:The operator judges product size, material quality and rolling conditions and sets volume controls 13, 14, 15 at proper values. For the head part and central part of a coil, mill speeds are finely adjusted, according to need, by means of successive mass controllers 7-9, and the fine adjustment signals of the mass controller are transmitted to mill motors by way of control circuit 1-3, whereby the fine acceleration and deceleration adjustment of the speeds is executed. At the time when the tail part of the strip leaves the (n-2) stand, a relay 4 acts to transmit the preset deceleration rate to the control circuit 1 via a volume control 13. This is then added with the signal from the mass controller 7 and is outputted to the mill motor, and the motor is decelerated by the volume amount. The same holds true of other n, (n-1) stands. When the tail end past-through the (n-1) stand, the relay 4 is reset and the value of the volume control 13 is cancelled.

摘要： PURPOSE:To roll the coil into the same breadth through the finishing pass, by calculating the roll gap of the edger in the roughing mill group at the coil tip and coil end according to the set value for the middle point of the coil, and by carrying out the timing rolling. CONSTITUTION:At the first, the set vale B0 of the roll gap to make breadth at the middle point of the coil to be the aim breadth is calculated. Next, the breadth contraction at the coil tip due to the interstand tension different according to the product size and the steel grade is specified, and the corrective amount bT of the finishing tension is calculated. Then, the breadth contraction at the coil end is specified, and the corrective amount bE is calculated. From these values, the set values for the coil tip and coil end are obtained by adding bT, bE, to the set value B0 for the middle point of the coil. Each of set values for the coil is inputted to CPU by the timing register attached to the horizontal roll 6, and the output of CPU is inputted to APC. Hereby, the breadth contraction at the coil tip due to the tension between finishing stands is corrected at the roughing pass, and the sheet breadth on the feed side of the finishing stand is spread as far as the breadth contraction than that of the middle point of the coil, and then, the sheet breadth at the tip and middle point of the coil are equalized. Further, the breadth at the coil end is also equalized to that at the middle point of the coil.
