摘要： The invention relates to an industrial plant and a method for adjusting a tensile stress of a strip (B), in particular a metal strip. The strip (B) is simultaneously guided by means of a first combination of rolls (2) and a second combination of rolls (3), for both (2, 3) of which an actual transfer of tension is determined (24, 25). In order to improve the operation of a plant for processing strip-shaped material, in particular metal strips, the actual transfers of tension of the first and second combination of rolls (2, 3) are adjusted by modifying the tensile stress of the strip between the combination of rolls (2, 3) in such a way that the respective actual transfer of tension approaches (26) a predefined desired transfer of tension of the first and second combination of rolls.

摘要： The invention relates to adjusting tensions between the mills of continuos hot rolling mill trains. The measurement of rolling parameters and adjustment of the torque of motors of said mills are carried out successively by groups of three. In the first adjustment stage, during the time between the moment when a work piece enters the first mill and the moment when it enters the second mill, a signal storing the value of a static load torque and the speed mode of the motors of the first mill is formed. In the second stage, during the time between the moment when the work piece enters the second mill and the moment when it enters the third mill, a signal indicating a change in the speed mode of the motors of the first mill is formed if said speed mode is different from the reference value, i.e. the minimum torque of the first stage. In the third stage, from the moment when the work piece enters the third mill, the ratio between the torque of the stored static load and the current value of the torque of the motors of the third mill is calculated, the signal of the difference therebetween being formed and the continuous adjustment of the speed mode of the first mill being carried out. In the fourth stage, when the work piece exits from the first mill, adjustment of motors of the first and second mills is interrupted. The signal formed in the third stage is stored.

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.
