Definitions

the invention relates to a method for adjusting a state of a rolling stock, in particular a Vorbands, which is defined by at least a wedge and / or saberiness of the rolling stock, wherein the rolling stock from an initial state by rolling by means of a roll stand, in particular a Vorgerüsts, and by embossing a tension in the rolling stock is transferred by means of additional processing means in an intermediate state, and wherein the rolling stock is transferred from its intermediate state by means of at least one processing unit in a final state.
a state of a rolling stock in particular a Vorbands, which is defined by at least a wedge and / or saberiness of the rolling stock
hot rolling mills In a rolling mill all the equipment needed for the production of rolled products can be combined. Depending on the type of forming hot and cold rolling mills are differentiated.
slabs or ingots, usually called slabs for short, are processed to hot strip.
This hot forming is one of the methods that follows the original forming (ingot casting, continuous casting).
the rolling stock is heated to temperatures up to 1350 ° C and preferably reduced above its recrystallization temperature in a rolling nip of the rolling mill by pressure to a predetermined thickness.
the overall complex of a hot rolling mill may include: primary stock; reheating furnaces; descaling; Roughing and finishing line with a different number of scaffolds, scaffolding groups and scaffold types; coilbox; Coolers; finishing equipment; Reel (s) and ready-made material store. Furthermore, bearings can be used for a rolling mill; Transport and management equipment and extensive control, and measurement systems belong.
the finished product usually steel or aluminum strip
several rolling stands are combined to form a rolling mill, in which several rolling passes are performed according to the number of scaffold runs.
hot rolling mills a distinction is made between the roughing mill and the finishing mill, whereby the slab is pre-processed in the roughing mill and then rolled to its final dimensions in the usually five-, six- or seven-stand finishing train.
the rolling stands represent the central parts of the plant.
the roll stands of the rolling stands must absorb the high rolling forces that occur and must stretch as little as possible.
the roll bearings of the roll stands ensure proper guidance of the rolls and transfer the rolling forces to the roll stand via the setting system, the setting devices of the setting system serving to horizontally and vertically position the rolls.
the adjusting devices can be actuated mechanically, electromechanically or hydraulically.
Quarto scaffolds which consist of two working and two back-up rolls, the back-up rolls usually have a larger diameter than the work rolls.
the rolling stock to be rolled in a roughing train has a thickness progression across its width.
the aim is usually to produce by means of rolling bands, on the one hand at the end of the finishing train has a substantially symmetrical to the band center thickness across the width, i. are free of wedges, and on the other hand have the least possible bending over the length of the rolling stock, i. are saber-free.
a wedge-shaped rolling stock is to be rolled out into a slab having a substantially rectangular cross-section
the volume flow on the "thicker" side of the slab results in a greater flow of material, in particular longitudinal flow, than on the "thin" side of the slab.
the consequence of this different material flow in the longitudinal direction of the rolling stock is the formation of a saber shape or a saber.
a saber-shaped rolling stock can lead to difficulties in subsequent processing of the rolling stock.
the formation of the saber can be so strong that further processing of the rolling stock is impossible.
WO 2006/119984 A1 is a method and apparatus for targeted influencing the Vorbandgeometrie known in a roughing stand, wherein in one or more roughing mills slabs are rolled into Vorb Sn.
a dynamic employment in the roughing stand with fast and powerful side guides before and behind the roughing stand are linked together so that in one or more stitches targeted, reversing or continuous operation, a saber or wedge Slab is transformed into a straight and wedge-free Vorband, a method can be provided, which makes it possible to produce just pre-tapes without thickness wedge and without lateral curvature.
Object of the present invention is to provide a generic method of the type mentioned, which increases the form of security for a final wedge-free, saber-free rolling.
the invention has for its object to provide a control device for performing such a method.
the procedural part of the object of the invention is achieved in a generic method in that it is determined whether the at least one processing unit to supply a rolling stock whose intermediate state requires a non-zero wedging and / or saberiness to achieve a predetermined final state, and depending on the rolling stand and / or the processing means are controlled and / or regulated for setting the respectively required intermediate state.
the final state is predeterminable, i. adjustable. For example, this can be characterized in that in the final state, a desired final thickness is reached and the rolling stock is substantially free of wedge and saber.
processing unit for example, an oven, a rolling train, a cooling unit or a cooling line or an aggregate for descaling
the intermediate state can be adjusted so that after processing of the rolling stock with the corresponding processing units a predetermined final state of the rolling stock is set.
the thicker side of the belt on the inlet side is the outlet side of the thinner belt side compared to the opposite side of the belt on the inlet and outlet side.
a desired final state can also be defined by leaving a certain residual chunking and / or saberiness of the rolling stock, since this is necessary for a subsequent application of the rolling stock in a product. This can be regarded as analogous to step plates.
the wedging and / or saberiness of a rolling stock can be set as desired by pivoting the work rolls in a roll stand. Without the aid of machining means, a change in the thickness wedge of a rolling stock in the rolling stand leads to a change in the saberiness of the rolling stock.
the prior art mentioned at the beginning shows how a wedge-free and saber-free pre-strip is produced by means of such processing means. But only by the present invention is the intermediate state, which may include, for example, the thickness of the rolling stock, width of the rolling stock, wedging of the rolling stock, saberiness of the rolling stock, etc., set such that only a desired final state is set by the subsequent processing units.
an intermediate state provided by means of the processing means and of the roll stand, is adjusted such that, for example, a wedge-free, saber-free strip with the desired final thickness is produced.
the stress which is impressed by means of processing into the rolling stock, can be stamped mechanically, thermally or by means of electromagnetic fields.
the processing means then set a desired tension or stress distribution at a certain point in the rolling stock, usually in the nip.
a mechanical processing means for impressing a voltage in the rolling stock are particularly advantageous a stamper and / or a strong side guide.
a symmetrical or asymmetrical tensile / compressive stress distribution or, if necessary, also a transverse stress distribution can be set, in particular at the roll gap, which reduces the material flow, i. Longitudinal flow of the material and lateral flow of the material, influenced.
the wedging and / or saberiness, possibly also the thickness of the rolling stock can be adjusted.
the impression of the tension by means of the processing means is controlled and / or regulated such that a desired stress distribution over the width of the rolling stock - in the rolling stock, at the nip - is set.
the initial state of the rolling stock, from which the rolling stock is transferred to the intermediate state, is usually taken into account. Because different initial states at the same settings of the manipulated variables of the roll stand and the processing means can lead to different intermediate states of the rolling stock. However, these differences in the intermediate states may not be desirable. Can do this the essential parameters characterizing the initial state of the rolling stock, such as wedging, saberiness, thickness, etc., are detected by means of corresponding detection devices. Thereby, the rolling stock can be suitably transferred from the initial state to the intermediate state taking into consideration the final state of the rolling stock and the properties of the subsequent aggregates.
the control and / or regulation takes place on the basis of a control and / or regulation model.
the parameters influencing the processing of the rolling stock are included in this model. These are composed of the parameters characterizing the rolling stock and of parameters which characterize an interaction of the rolling stand, the processing means and the at least one subsequent processing unit or several subsequent processing units with the rolling stock.
usable models are, for example, the DE 101 18 748 A1 : “Method and control for process-controlled modeling of a process plant” removable and about the textbook Chritianini, Shawe-Taylor: “An introduction to support vector machines and other kernel-based learning methods", Cambridge UP, 2000 , This is only a short excerpt of possibilities that the skilled person can fall back on.
a model is preferably designed to be on-line capable, ie, during operation of the steelworks, adjusting the control and / or control of the rolling stand and processing means such that the intermediate state in real time depends on the final state and the interaction parameters of the rolling stock machining processing units is set such that a predetermined final state of the rolling stock is achieved by processing with the subsequent units.
an inner, in the further processing of the rolling stock at least on the wedging and / or saberiness of the rolling stock effecting material strain is taken into account in the determination.
a relaxation of the material distortion acting on at least the wedging and / or saberiness of the rolling stock in one or more subsequent processing units, such as furnace or cooling section or finishing train is included in the adjustment of the intermediate state of the rolling stock. Thereby, a further improvement of the setting of the intermediate state can be achieved.
the material tension in the rolling stock can be measured.
the material tension will be modeled by suitable models.
a coupling of measurement and calculation of the material tension in the rolling stock can be provided.
the voltage impressed on the rolling stock is controlled and / or controlled.
the processing means are controlled and / or controlled so that they set a desired tension, in particular stress distribution across the width of the rolling stock.
the rolling stock is brought into an intermediate state in cooperation with the possibly dependent control and / or control of the manipulated variables of the actuators of the rolling mill, which leads to the desired final state when working with at least one subsequent unit.
