摘要： A control device controls a hydraulic cylinder unit having a piston. The device receives a setpoint variable and an actual variable and determines, based on a difference between the setpoint variable and the actual variable, a preliminary manipulated variable for valves of the hydraulic cylinder unit. The setpoint variable and the actual variable relate to a position of the piston or a force applied by the piston. Linearization factors are determined dynamically as a function of the actual position of the piston and working pressures on both sides of the piston and a hydraulic fluid tank/pump. Definitive manipulated variables to control the valves are determined from the preliminary manipulated variable and the linearization factors. With the linearization factors, a ratio of the piston adjustment speed to the difference between the setpoint variable and the actual variable is independent of the actual position of the piston and the working pressures.

摘要： A flat rolled material (1) is transported through a cooling zone (2) such that portions (15) of the rolled material (1) successively pass through effective ranges (8, 9) of cooling installations (6, 7). Virtual rolled material points (P) are assigned to the portions (15). During transportation of the portions (15) through the cooling zone (2), tracking of the portions (15) is carried out by way of an operating cycle (δt′). The cooling installations (6, 7) are controlled so as to correspond to the respective rolled material points (P) for actual cooling outputs (mi) which are assigned to the cooling installations (6, 7). On account thereof, that portion (15) that is in each case located in the effective range (8, 9) of the respective cooling installation (6, 7) is impinged with a respective amount of coolant. The cooling installations (6, 7) are subdivided into released and non-released cooling installations. A rolled material point (P) is in each case iteratively selected. Before the corresponding portion (15), proceeding from a starting point (xA), reaches the effective range (8, 9) of the next released cooling installation (6, 7), a state (E) which the respective rolled material point (P) has at the starting point (xA) is determined.

摘要： A method for cooling a rolled product in a cooling section which is located upstream of a finishing train of a hot rolling mill. The cooling section includes a cooling device which can deliver a coolant flow of a coolant onto a rolled product surface of the rolled product. In the method, a coolant flow is delivered, by means of each cooling device and in each cooling section pass, onto the rolled product surface, which flow is set to a set value that is assigned to the relevant cooling device for the cooling section pass. The set values for a cooling section pass are determined in a simulation of the cooling section pass so that surface temperatures, determined in the simulation, of the rolled product surface upon leaving active regions of the cooling device do not exceed a minimum value for a surface temperature of the rolled product surface.

摘要： A position controller that controls an actuator that sets a roll gap of a roll stand by determining an actuating variable (q) for the actuator as a function of a resulting position target value (s*) and a position actual value(s) of the actuator. The (s*) is determined with a resulting base target value (s1*), which is determined as the sum of an initial base target value (s0*) and an additional target value (δs1*), which is determined by a determination element with an inlet-end actual tension (ZE) and an inlet-end reference tension (ZER) and/or with an outlet-end actual tension (ZA) and an outlet-end reference tension (ZAR). Instead of (ZE) and (ZA), the corresponding target tensions (ZE*, ZA*) of corresponding tension control operations can also be used. However, in both cases, (ZER) and (ZAR) are variables that differ from (ZE*) and (ZA*).

摘要： A processing plant for metal strips (1) has a welding machine, a strip store downstream of the welding machine and a processing device downstream of the strip store. The metal strips are welded to form a continuous strip with the welding machine, which is stored in the strip store and output from there to the processing device. The metal strips are connected via diagonally extending weld seams. To join the weld seams, first the strip head (2) and the strip foot (3) of the metal strips are twisted and the two strips are connected by forming the weld seam. The weld seam extends only transversely to the transport direction (x) during the welding process. Finally, the strip head and the strip foot of the metal strips are twisted back again. As a result, the weld seam now extends diagonally to the transport direction (x).

摘要： A cooling section (2) is situated in a rolling line or upstream or downstream of the rolling line. A hot metal rolled material (1) is cooled in the cooling section. A control device (13) of the cooling section (2) dynamically determines setpoint actuation states (S1*) for control valves (10) situated in supply lines (8) and actuates the control valves (10) accordingly. Main flows (F1) of a liquid, water-based coolant (7) are supplied to application devices (6) of the cooling section (2) via the supply lines (8) in accordance with the actuation. The supply lines (8) conduct the main flows (F1) to buffer regions (12) of the application devices (6). Proceeding from there, cooling flows (F) of the coolant (7) are applied to the hot rolled material (1). The control device (13) also dynamically determines setpoint actuation states (S2*) for active devices (16) and actuates the active devices (16) accordingly. The active devices (16) conduct additional flows (F2) of a further medium (18) to the buffer regions (12) via further supply lines (17) in accordance with the actuation. The cooling flows (F) depend on both the main flows (F1) and the additional flows (F2). The additional flows (F2) are positive or negative depending on the actuation state (S2*) of the active devices (16). The control device (13) adjusts the additional flows (F2) by correspondingly actuating the active devices (16) such that the cooling flows (F) are as identical as possible to setpoint flows (F*) of the coolant (7) at all times.

摘要： Slabs pass through a furnace in a conveying direction, are heated to rolling temperature, and are rolled in at least one roller stand. Determining device receives information showing the regions occupied by the slabs relative to one another when passing through the furnace in at least one direction orthogonal to the conveying direction, and determines, for at least one rolling pass of the respective slab, an adjustment of the roller stand performing this rolling pass without prior determination of a respective temperature distribution of a respective slab or without utilization of a determined temperature of a respective slab. The determining device takes into account the region occupied by the respective preceding and/or following slab, seen in the conveying direction, relative to the respective slab, and supplies the respective determined adjustment of the roller stand to a control device, which controls the roller stand when the respective slab is being rolled.

摘要： A model (8) is based on mathematical-physical equations. The model models the production of a particular output product (1) from at least one input product (2) supplied in each case to an installation in the raw materials industry on the basis of operation (B) of the installation. During production of the output products (1), the installation is controlled by a control device (5) in such a manner that particular actual operation (B) of the installation corresponds as far as possible to particular desired operation (B*) of the installation. The desired operation (B*) is determined by the control device (5) using the model (8) of the installation. The model (8) is parameterized according to a number of first model parameters (P1) for the purpose of modelling the installation. After a multiplicity of output products (1) have been produced in each case, actual sizes (A) of the output products (1) in the particular multiplicity are compared with expected sizes (A′) of the output products (1) in the particular multiplicity. On the basis of the comparison, the first model parameters (P1) are newly determined and the model (8) in the control device (5) is newly parameterized according to the new values of the first model parameters (P1). After this time, the desired operation (B*) is determined by the control device (5) using the newly parameterized model (8) of the installation in the raw materials industry. The expected sizes (A′) are determined by means of the model (8), wherein the determination of the expected sizes (A′) is based on the actual operation (B) of the installation.
