Definitions

  • the invention relates to a method for producing steel strips by endless rolls or semi-endless rolls, wherein first in a casting plant, a slab is poured, the slab is rolled in a roughing mill to a pre-strip, the pre-strip is heated in an oven and the heated pre-strip in one Finishing mill is rolled to a predetermined final thickness and a predetermined Endwalztemperatur finish.
  • the emerging from the casting slab is usually descaled, pre-rolled, the resulting pre-strip is heated in an oven and rolled finished in the finishing train.
  • the finishing train usually hot rolled, that is, the rolling stock during rolling a Temperature above its recrystallization temperature. For steel, this is the range above about 720 ° C, usually is rolled at temperatures up to 1200 ° C warm.
  • the metal is usually in the austenitic state, where the iron atoms are arranged cubic face centered.
  • the austenite area of a steel depends on the steel composition, but is usually above 800 ° C.
  • a correspondingly high final rolling temperature is usually specified in the pass plans.
  • the continuous rolling or semi-continuous rolling of steel strips is well known from the prior art, as are the disadvantages that result from it: in particular in continuous rolling transmits each fluctuation in the casting process to the rolling process by the direct coupling of casting and rolling.
  • continuous rolling transmits each fluctuation in the casting process to the rolling process by the direct coupling of casting and rolling.
  • fluctuations in the speed and the temperature of the preliminary strip can occur, which in turn has an effect on the finish rolling of the steel strip and can lead to quality fluctuations.
  • the mass or volume flow of the Vorbands may change and / or the temperature of the Vorbands.
  • the mass or volume flow changes z. B. if, with the same thickness and width of the Vorbandes the speed of the Vorbandes changes or if the thickness changes with the same width and speed of the Vorbandes.
  • the width-specific volume flow is often used in the rolling technique, ie as a volume flow per unit width (1 m), which can be represented as a product of the thickness of a belt and belt speed, in particular if the width of the belt plays no special role for the process in question. This often applies when the width is at least seven to ten times the thickness.
  • the (broad specific) mass flow is known to be obtained by multiplying the (specific volume) volume flow by the density of the belt.
  • the microstructure of the steel strip may deviate from the desired microstructure, such as an austenitic microstructure. But it can also come to deviations from the desired thickness or the desired profile of the steel strip. But the quality of the finished steel strip can also be so bad that it has to be treated as scrap.
  • the DE 10 2007 058 709 A1 on the other hand, to determine a functional relationship between casting speed or mass flow on the one hand and final rolling temperature on the other hand for a certain number of active rolling stands and different final thicknesses, to determine the optimum number of active rolling stands on specification of a certain casting speed or mass flow, with which a desired final rolling temperature is achieved and optionally a number of rolling stands drive so that only the optimum number of rolling stands is active.
  • Such a method is also applicable in the case of start-up of the endless compound system, when the broadly specific mass flow or volume flow of the pre-strip increases slowly.
  • a change in the inlet temperature of the pre-strip when entering the finishing train by more than 1 K / second or the inlet mass flow of more than 0.2% / second corresponds to the conditions when starting the G transparentwalz composite system and provides a constant or slow change of inlet temperature and Inlet mass flow.
  • the values of more than 5 K / second or more than 1.5% / second correspond to the values of a disturbance of the cast roll compound system and represent a significant and mostly also suddenly occurring change of inlet temperature and inlet mass flow.
  • Energy can also be saved if the inlet temperature is lowered, ie the temperature with which exits the subband from the oven and enters the finishing train. This will be possible in particular if the number of active rolling stands of the finishing train is reduced by one and in the remaining active rolling stands thickness reductions of the steel strip close to the maximum possible reduction degrees (relative change in thickness of the steel strip after and in front of the rolling stand), because thereby per rolling stand more dissipative forming heat is generated, which additionally heats the steel strip.
  • the maximum possible reduction rates are determined on the one hand by the material properties of the steel strip itself, on the other hand by the roll stand, which can muster only a finite rolling force.
  • the term "if possible within plant-technical limit values" therefore means that the originally desired final thickness may be sought only if this is possible within the limit values applicable to the finishing train, in particular the maximum permissible rolling and bending forces. This will usually be possible if the inlet temperature or the inlet mass flow increase and an additional rolling mill is switched on.
  • the originally desired final thickness can, however, possibly not be maintained if the inlet temperature or the inlet mass flow sink and a rolling stand is driven up because in some cases the rolling and bending forces of the finishing train needed to maintain the final thickness would exceed the corresponding limit values. It must therefore be allowed a greater final thickness, which must not be a disadvantage if later in the rolling program anyway a larger final thickness is to be rolled.
  • the rolling stock ie the steel strip
  • the rolling stock is described at any time during the rolling process and thus also in the stitch plan at least by the following variables: speed, thickness, temperature and relative profile (thickness of the strip in the middle relative to the edge).
  • Each roll stand is characterized - also in the pass chart - at least by the following variables, which simultaneously represent the manipulated variables of the roll stand: peripheral speed of the work rolls, rolling force and bending force.
  • the new stitch plan is determined during the ongoing rolling process.
  • the new pass schedule can be recalculated with the aid of the current measurement data of the rolling process and therefore particularly accurate.
  • this procedure will lead to comparatively worse results than the calculation of the new pass schedule during the rolling process ( online calculation).
  • the new stitch plan according to the invention is best created by means of a mathematical process model that simulates the rolling process of at least all rolling mills of the finishing train. During the rolling process, the rolling process in the finishing train can be recalculated several times per minute due to the process model.
  • the final rolling temperature, the final thickness, the rolling and bending forces required per framework and the energy requirements of the finishing wharf and the furnace can be calculated. Then the distribution of the rolling force on the individual rolling stands and also the number of active rolling stands is varied and thereby determined whether an active rolling mill would be less energetically advantageous in compliance with plant limits and operational limits.
  • a so-called objective function can be formed, which is a mathematical optimization, such.
  • B. an extreme value formation, is subjected, and the determined in this way function values of the objective function are used to create a stitch plan.
  • the function values of the objective function determined by the optimization can be used directly as parameters of the stitch plan.
  • the objective function is a function of state variables of the rolling stock, such as speed, thickness, temperature, relative profile, and / or control variables, such as peripheral speed, rolling force, bending force.
  • the objective function will be the energy supplied to the furnace and / or the finishing train so that, for example, a very low energy pass schedule is calculated. Because at least one condition imposed on the pass schedule in the form of a limit value is taken into account as a secondary condition during the optimization, plant technology or technological limit values are included in the optimization in a simple manner. Furthermore, at least one condition that specifies a fixed value for a control or state variable is considered as a constraint in the optimization. As a result, defined values, just the desired final thickness and the final rolling temperature, can be incorporated into the optimization.
  • the stitch plan may be used for which, under given constraints, the solution with the smallest violation of the constraints occurs. For example, a deviation from the desired final thickness may be allowed if such a product had to be manufactured anyway at a later date according to the production plan. But at least a final rolling temperature can be achieved, where the metal is in the austenitic state.
  • the process model of the stitch plan at least the final rolling temperature of the steel strip, the final thickness of the steel strip, and the combined energy demand of the finishing train and the furnace is calculated, the number of rolling stands varies and the associated energy for the rolling stands and the Furnace is determined, and if, in accordance with predetermined limits for the settings of the rolling stands and the furnace, a variation in a reduction of the common energy requirement results, this is based on the new pass schedule.
  • Another way to minimize the energy required for the furnace is to increase the thickness of the pre-strip is changed.
  • the rolling stands of the rough rolling mill must also be included in the new pass schedule to be recalculated.
  • the thinner the pre-band is, the lower the energy required to heat the pre-band in the oven.
  • the aim here is to select the pre-strip thickness at given values for intake mass flow, end strip thickness and final rolling temperature so high that the active rolling stands of the finishing train are as close as possible to the maximum possible reduction levels to replace the energy saved at the furnace by the dissipative forming heat.
  • the temperature of the steel strip as it exits the furnace should generally not exceed 1250 ° C, more preferably be less than 1220 ° C. However, if the reduction levels in the rolling mills of the finishing train are increased, the temperature of the steel strip as it exits the furnace may be lowered to, for example, about 1090 ° C.
  • the method according to the invention can be used both for endless rolling or semi-endless rolling.
  • it can be used for startup and startup of a cast roll compound plant after a casting-rolling break, ie the daily restart of the plant and not only after a plant shutdown due to an error.
  • it is used for semi-endless rolling, then there are basically two possibilities when the stitch plan change takes place and thus, when a rolling stand for the implementation of the new stitch plan is switched on or driven.
  • the pre-strip to be rolled may already be in the finishing train when a rolling stand is brought into rolling engagement or out of rolling engagement.
  • Semi-continuous rolling produces several pre-bands from the split slabs, which run into the finishing train relatively just one behind the other, usually only with a time interval of less than 20 seconds, preferably less than 10 Seconds, especially less than five seconds.
  • the connection or driving of a rolling mill is carried out regardless of whether a steel strip is in the finishing train or not. Therefore, it is likely to take place when there is just a steel strip in the relevant rolling stand.
  • the pre-strip to be rolled during semi-endless rolling only enters the finishing train when a rolling stand has been opened or closed in accordance with the new pass schedule. That is, it must be arranged in front of the finishing train a pair of scissors, which cuts through the opening band, so that that part which is already in the finishing train, can be accelerated out of the finishing train, while not yet in the finishing train part enters the finishing train (or at least not in the rolling mill to be adjusted) until the corresponding rolling mill has been adjusted according to the new stitch plan.
  • the cutting of the pre-strip is not a disadvantage, because a finished strip is usually too long for a bunch and therefore anyway must be cut after the finishing train at least once to wind it up to at least two coils. So you can perform the cut of the steel strip instead of after the finishing mill before the finishing mill and thus simultaneously create a break for the necessary conversion to the new stitch plan.
  • the roll gap per second can be increased or reduced by about 5 mm.
  • the method according to the invention can be carried out with the aid of a computer program product which, when loaded and executed on a computer, determines a pass schedule according to one of the method claims.
  • Either the total energy consumption of the furnace plus the finishing train or only the energy consumption of the furnace can be minimized, in particular with a constant or slowly changing input state (inlet temperature and mass flow).
  • the inventive method requires only a small control effort in the actuators for the strip temperature (oven, cooling).
  • the inventive method allows a very early start of finish rolling after casting start, even if the inlet mass flow is still relatively low.
  • the strip thickness can be gradually reduced as the inlet mass flow and / or the heating power of the furnace are gradually increased.
  • the invention will be explained by way of example with reference to a schematic figure.
  • the figure shows the side view of a cast roll compound system.
  • FIG. 1 an embodiment of a cast-roll composite plant is sketched on which the inventive method for producing steel strips 1 can be performed.
  • a vertical caster 2 available in the slabs 3 are cast, for example, 70 mm thickness.
  • cutting could be carried out to a desired slab length during semi-endless rolling.
  • a first oven 6, in which the slab 3 is brought to about 1000 to 1200 ° C rough rolling temperature T1 and in which there is a certain temperature compensation in the width direction.
  • the oven 6 can also be omitted.
  • a rough rolling 4 which may consist of a - as here - or of several stands and in which the slab 3 is rolled to an intermediate thickness or Vorbanddicke.
  • a rough rolling 4 which may consist of a - as here - or of several stands and in which the slab 3 is rolled to an intermediate thickness or Vorbanddicke.
  • the transformation of cast structure into the fine-grained rolling structure takes place. It is also possible to dispense with the use of a scale washer 13 or another system for descaling upstream of the rough rolling mill 4.
  • the furnace 7 may preferably be designed as an induction furnace, but also as a conventional furnace or as a high-temperature furnace with flame treatment.
  • the pre-strip 3 ' is brought relatively uniformly over the cross section to the desired inlet temperature T2 for the inlet to the finishing train 5, wherein the inlet temperature T2 usually depending on the steel grade and subsequent rolling in the finishing train 5 between 1090 ° C and 1250 ° C. lies.
  • the inlet mass flow of the Vorbandes 3 'in the finishing train 5 is still relatively low ( ⁇ 70% of the intake mass flow during normal operation), is rolled only with the first three rolling stands 51-53. If now the inlet mass flow increases continuously, in order to achieve the desired final thickness and final rolling temperature, first the fourth rolling stand 54, then in a further step, the fifth rolling stand 55 and possibly also the sixth rolling stand 56 closed, so active. Before connecting a further roll stand, the temperature in the furnace 7 and thus the inlet temperature T2 of the pre-strip 3 ' would decrease with increasing inlet mass flow. As soon as another scaffold is switched on or closed, the inlet temperature must be raised significantly, typically between 35 and 55 K, for reasons of economy or product quality 1250 ° C, more preferably 1220 ° C surface temperature should not be exceeded.
  • one additional rolling stand 51-56 is opened or closed to achieve the desired final thickness and finish rolling temperature.
  • the pre-strip thickness is to be selected so high that at the lowest possible inlet temperature, eg 1090 ° C, the three, four or five currently still active rolling stands with maximum reduction ratios, ie at the technical limits of the rolling stands, the desired steel strip just can still produce ,
