摘要： A temperature control apparatus of a hot-rolling mill according to the present invention extracts a high-frequency component, a medium-frequency component, and a low-frequency component from a deviation between a calculated value or a measured value of a material temperature in a temperature managing position set on an outlet side of the hot-rolling mill and a given temperature target value. The temperature control apparatus then corrects a reference value of electric power of an induction heating device set to an electric power changing device based on the high-frequency component, corrects a reference value of a cooling water flow rate set to a flow rate changing device based on the medium-frequency component, and corrects a reference value of a roll rotation speed set to a speed changing device based on the low-frequency component.

摘要： When the tracking point reaches the i-th stand, the continuous rolling system outputs, to an i-th stand, a roll gap operation value for bringing to zero a difference between a value which is obtained by correcting a strip thickness target value of the i-th stand with a target strip thickness correction value of the i-th stand and a value which is obtained by correcting a strip thickness actual recalculation value of the i-th stand with a gap correction value of the i-th stand. Here, the gap correction value is a correction value that brings to zero a difference between a head end gap error when a head end of the material to be rolled reaches the i-th stand and a non-head end gap error when a part other than the head end of the material to be rolled reaches the i-th stand.

摘要： The prediction system of strip chew collects and stores first data and second data as adaptive model construction data. The first data indicates the occurrence or non-occurrence of the strip chew in an object rolling path and the occurrence point of the strip chew. The second data includes information on a preceding rolling path and attribute information on an object strip. The system constructs an adaptive model using the stored adaptive model construction data, and stores the constructed adaptive model as an adapted model. The system collects prediction data similar to the second data. Then, the system inputs the prediction data to the adapted model to predict the occurrence or non-occurrence of the strip chew in the object rolling path and all or some of the occurrence points of the strip chew before the prediction object strip reaches the object rolling path.

摘要： A motor speed control device for a rolling mill, which includes a rolling roll that rolls a metal material, a roll rotation shaft directly connected to the rolling roll, a motor rotation shaft that transmits power to the roll rotation shaft, and a motor that drives the motor rotation shaft, includes: a non-contact type speed sensor arranged at a position close to the rolling roll with spacing to a circumferential surface of the roll rotation shaft to detect a roll rotation shaft angular speed of the roll rotation shaft; and a speed controller that controls a speed of the motor based on a comparison value between an actual value and a target angular speed of the rolling roll so that the actual value coincides with the target angular speed. The actual value is the roll rotation shaft angular speed to be fed back to the speed controller.

摘要： A plate crown control device controls tandem rolling equipment based on delivery-side plate crown setting calculation values of stands calculated by setting calculation, mechanical plate crown setting calculation values of the stands, and setting values of bending forces and shift positions of the stands. A processor calculates first learning current values based on differences between mechanical plate crown observation values and mechanical plate crown actual calculation values. The processor prorates first learning values with first learning current values and smoothing gains and updates the first learning values. The processor calculates, in the setting calculation for the next and subsequent materials, setting values of bending forces and shift positions of the stands using mechanical plate crown setting calculation values after correction obtained by adding the first learning values to the mechanical plate crown setting calculation values.

摘要： A plate thickness schedule calculation method includes a plurality of steps. One step acquires a rolling model expression including a roll force model or a motor power model. Another step determines whether or not a parameter restriction has occurred that restricts at least one parameter of roll force, motor power and a reduction rate in each rolling stand. Further another step is to select a first derived function when no parameter restriction occurs and to select a second derived function when the parameter restriction has occurred in accordance with a result of the determination for each rolling stand. Still another step modifies each delivery side plate thickness in each rolling stand using a matrix including the one derived function selected from the first derived function and the second derived function in accordance with the result of the determination.

摘要： When an opposite direction shift for obtaining a required equivalent roll crown and a same direction shift for wear dispersion are used in combination, a difference occurs in the roll gap at both edge portions in the width direction of a rolling target material. Therefore, the difference between a work-side screw down position and a drive-side screw down position is changed so that the roll gap difference between both the edge portions in the width direction of the rolling target material is made close to zero. As a result, the distance between the work roll shafts on a work side and a drive side is changed, so that the roll gap difference at both ends in the width direction of the rolling target material approaches zero. Therefore, the wear of the work rolls can be dispersed while maintaining the equivalent roll crown.

摘要： A cooling-water injection control device and a cooling-water injection control method for a rolling mill suppress influence by change in flow rate characteristics of water injection headers. The cooling-water injection control device for a rolling mill includes a water injection amount control unit. When a plurality of water injection headers are controlled to make temperature of a material to be rolled on a delivery side of a rolling mill coincident with a target value, in a case where a flow rate of any one of the plurality of water injection headers is less than a transient flow rate between a minimum flow rate and a maximum flow rate, the water injection amount control unit controls a flow rate of any one of the plurality of water injection headers based on priority.
