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.

The invention relates to a device (1) and a method for laterally guiding a slab (2) on a transport track (3), comprising a first guide rule (4) and a second guide rule (5). The guide rules (4, 5) are arranged opposite each other on both sides of the transport track (3) and are each connected to at least one actuating drive (6) so as to move in a direction of a width of the transport track (3). The actuating drive can be actuated perpendicularly to the transport direction (7) of the slab (2), wherein the respective longitudinal axis (4 L , 5 L ) of the first guide rule (4) and/or the second guide rule (5) can be positioned at a specified angle (α) relative to the transport direction (7) of the slab (2). The first and/or the second guide rule (4, 5) has at least one contact roller (8) which can be brought into contact with a lateral edge of the slab (2) in order to guide and/or compress the slab (2).

Provided are hot rolling equipment and a hot rolling method for precisely controlling the meandering and plate shape of a steel strip, thereby making it possible to prevent tail end squeezing of the steel strip. Hot rolling equipment (10) for this purpose, for sequentially passing a steel strip (1) through rolling machines (11, 12) and thereby rolling the steel strip (1), wherein a plurality of split rolls (63) capable of contacting the steel strip (1) is provided between the rolling machines (11, 12), and, when the split rolls (63) contact the steel strip (1), detection torques (Td, Tw) acting on the left and right ends of the split rolls (63) are detected by torque detectors (67a, 67b), the reduction leveling of the rolling machines (11, 12) being adjusted on the basis of the detected detection torques (Td, Tw) to control the meandering and plate shape of the steel strip (1).
摘要:
Einem Steuerrechner (3) für eine Walzstraße werden Gerüstparameter eines Walzgerüsts (2) der Walzstraße vorgegeben. Der Steuerrechner (3) setzt im Rahmen einer Stichplanberechnung einen Walzstich des Walzgerüsts (2) beschreibende Größen (F, δF, G, δs, V) an, die in Verbindung mit Anfangsdaten (b, d, T) eines zu walzenden flachen Walzguts (1) und den Gerüstdaten den sich ergebenden Walzspalt und dessen Asymmetrie beschreiben. Die Anfangsdaten (b, d, T) umfassen zumindest die Breite (b), die mittlere Dicke (d) und die mittlere Festigkeit des Walzgutes (1). Der Steuerrechner (3) ermittelt in der Stichplanberechnung anhand der Anfangsdaten (b, d, T), der Gerüstdaten und der angesetzten Größen (F, δF, G, δs, V) einen erwarteten Auslaufkeil (K) und/oder einen erwarteten Säbel (K') für das Walzgut (1). Der Steuerrechner (3) variiert mindestens eine der angesetzten Größen (F, δF, G, δs, V), um den ermittelten Auslaufkeil (K) einem Sollauslaufkeil und/oder den Säbel (K') einem Sollsäbel zumindest anzunähern. Der Steuerrechner (3) übergibt die ermittelten variierten Größen (F, δF, G, δs, V) an eine Basisautomatisierung (8) des Walzgerüsts (2), so dass das Walzgut (1) im Walzgerüst (2) gemäß den variierten Größen (F, δF, G, δs, V) gewalzt wird.
摘要:
The invention relates to a strip (4) comprising a strip head (10) and a strip leg (11). It is rolled, beginning at the strip head (10), in a roll stand (1) of a rolling device between an upper and a lower roller arrangement (2, 3) of the roll stand (1). It is monitored whether the strip foot (11) reaches a switching point (12) located, viewed in the rolling direction (x), in front of the roll stand (1). From the time the strip leg (11) reaches the switching point (12), the roller arrangements (2, 3) are subjected to a bending force (F) expanding the roller arrangements (2, 3) by means of an adjusting device (5), the force being at least as high as a minimal force. The minimal force is at least as high as a balancing force of the upper roller arrangement (2). The minimal force is determined as a function of the parameters of the strip (4) and/or the operating parameters of the rolling device.
