摘要： The invention relates to a method for increasing the process stability, particularly the absolute thickness precision and the installation safety during the hot rolling of steel or nonferrous materials, with small degrees of deformation (f) or no reductions while taking the high-temperature limit of elasticity (Re) into account when calculating the set rolling force (Fw) and the respective setting position (s). The process stability can be increased with regard to the precision of the yield stress (kf,R) and the set rolling force (Fw) at small degrees of deformation (f) or small reductions, during which the high-temperature limit of elasticity (Re) is determined according to the deformation temperature (T) and/or the deformation speed (phip) and is integrated into the function of the yield stress (kf) for determining the set rolling force (Fw) via the relation (2) Re=a+eb1+b2·T.phipc, in which: Re represents the high-temperature limit of elasticity, T represents the deformation temperature; phip represents the deformation speed, and; a, b, c represent coefficients.

摘要： A continuous hot rolling method includes setting operating conditions (OC) for hot rolling facilities, regarding rolled material for which endless rolling was planned, in which a preceding piece of material and a subsequent piece of material are joined to each other, to batch rolling, in which rolling is performed without joining the preceding piece of material and subsequent piece of material to each other, or setting of changes from batch rolling to endless rolling. Changes can be speedily and accurately made, so that operating problems, or defective coils due to inaccurate changes in settings or delays in changing the settings can be prevented. Both the operating conditions (OCIe) for endless rolling and the operating conditions (OCIb) for batch rolling are predetermined, and the operating conditions (OCe,OCb) for the facilities at various positions on the hot rolling line are determined for both endless rolling and for batch rolling.

摘要： A method of rolling rod-shaped rolling stock, particularly rod steel or wire, in a roll stand having two work rolls which are adjustable relative to each other in an adjusting direction and which together form a roll groove with an actual roll gap, so that the rolling stock exits the roll stand with an actual height and an actual width at a rolling speed, wherein the rolling stock is rolled with an actual rolling force. The method includes the steps of adjusting the work rolls through a hydraulic cylinder unit; measuring the actual rolling force; measuring with the aid of the actual rolling force a roll gap spring-back resulting from the rolling force; determining with the aid of the roll gap spring-back and a desired roll gap a roll adjustment correction value such that the actual roll gap approaches the desired roll gap; and changing a roll adjustment within a stand control time by the roll adjustment correction value.

摘要： In the control of a material-processing process in a regulated system, a preliminary adjustment of the system takes place at the beginning of each process cycle as a function of a precalculated process parameter. A material characteristic which is relevant for the process and which in turn is dependent on state variables (such as the composition of the material and its temperature), is included in an advance calculation of the process parameter. The relationship between the state variables and the material property is modelled in a neural network which forms a prediction value for the material property on its output side. As a function of the deviation between the prediction value and an actual value for the material property which is determined based on measuring the process parameter during the process cycle, an adaptive change of the network parameters takes place in the sense of reducing this deviation.

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 feedback control of a hot and/or cold rolling process by means of a process control system, which executes a predetermined rolling program containing the initial and final dimensions, material data, roll temperatures, etc., and has a master system for controlling the setpoint values of subordinate, preferably decoupled, individual control units for the variable functional variables of the individual roll stands, e.g. rolling force, rotational speed, screw-down position [setting], etc. The setpoint values of the control units are determined in a computational operation using model equations, in which prepared and statistically processed measured values of the process variables are substituted, with convergent adaptation of absolute parameters to the actual parameters. In the event of changes in the requirements of the rolling process, in particular in the event of a transition from manual to automatic operation, or of changes in the final thickness, and/or changes in temperature, a relative adaptation of the parameters is carried out on the basis of the set values used before the changes in requirements as initial values.
