摘要： During rolling of front sections of rolling material in a rear group of roll stands of a rolling mill, rear sections of the rolling material are rolled in the front group of roll stands. A run-out speed with which the rolling material is exiting the front group of roll stands is detected. A run-in speed with which the rolling material is entering the rear group of roll stands is detected. A rolling speed with which the rear group of roll stands is driven is controlled by a controller such that a relation of the run-in speed to the run-out speed equals a predetermined value. The predetermined value is kept constant until a time point at which a tail end of the rolling material reaches a predetermined location upstream of the front group of roll stands, and is changed according to a predetermined function after the time point.

摘要： A system for controlling a thickness of a strip being rolled by a rolling mill having more than two rolling stands, in tandem configuration. A subcontrol unit controls a rolling speed and a rolling load of a final rolling stand according to a predetermined control schedule. A plurality of tension gauge units installed between adjacent rolling stands detect a tension of the strip. A plurality of thickness gauge units including at least first thickness gauge unit installed on the output side of a first rolling stand, second thickness gauge unit installed on the output side of a penultimate rolling stand, and final thickness gauge unit installed on the output side of the final rolling stand, detect a deviation in the thickness of the strip from a predetermined value. A thickness control unit, connected to the tension gauge units and the thickness gauge units, controls the thickness and the tension of the strip to respective predetermined values by adjusting a roll gap and the rolling speed of the rolling stands except the final rolling stand, based on the detected tensions and the detected deviations of the strip. A feedback unit controls a rolling speed of an antepenultimate rolling stand according to the detected deviation of the last thickness gauge unit and the detected deviation of the second thickness gauge unit to adjust the thickness of the strip to the predetermined value.

摘要： A setting means sets variables for expressing the process model, a target thickness value of the rolled material, a target interstand tension value of the rolled material, variables for responses of the thickness and the interstand tension and variables for adjusting the responses of a control system for controlling the thickness and the interstand tension. A control gain arithmetic means obtains control gains as numeric values by substituting the set variables into predetermined control gain operation expressions. A control arithmetic means calculates the speed command values and the roll gap command values for causing the thickness to follow up the target thickness and the interstand tension to follow up the target interstand tension while reducing an interaction between the thickness and the interstand tension by use of the calculated control gains.

摘要： A cascade speed control for tensionless production in a rolling mill by the measurement of stand motor current with temperature compensation. A low tension speed ratio between pairs of mill stands is calculated by successive incremental corrections. The corrections are based on the difference between a no tension current and a tension current for the motors of the mill stands as compensated for temperature variation. In one embodiment a compensation factor is calculated by taking the temperature difference of the material at the times the currents are measured and multiplying the difference by an empirical constant which relates the change in motor current to a change in temperature for a particular plant. Another embodiment illustrates temperature compensation by using current compensation values which are obtained by storing a no tension current profile for one of the mill stands. The low tension speed ratios between stands are maintained by cascading variations in the speed of a subsequent stand down to a previous stand.

摘要： The invention involves a procedure having three key stages: In the first stage, just prior to the introduction of the metal into stand (n+1), the value of the rolling torque in stand (n) is determined and recorded. Then, in the second stage, when the metal is introduced into stand (n+1), the value of the rolling torque in stand (n) is held constant by controlling the speed regulator of stand (n) up to the time the metal is introduced into stand (n+2). Finally, in the third stage, which continues until the rolling operation in stand (n) has been completed, the voluminal flow of the metal is held constant at the line of each stand by applying a multiplier coefficient to the signal representing the ratio between the speeds of two successive stands.

The interstand tension is computed on the basis of the computed torque arms l.sub.1, l.sub.2, and detected rolling torques G.sub.1, G.sub.2 and rolling forces P.sub.1, P.sub.2, and the roll drive main motor is regulated to compensate the deviation of the computed interstand tension from the desired value to maintain the interstand tension constant throughout the rolling operation.
