根據步驟f)的鋼帶加熱可以包含感應式加熱。或者， 可以實現鋼帶的直接火焰衝擊（仙⑽flame impingement)。在後者的情形中，較佳的是可藉由含有至 少75%氧氣、較佳地含幾乎純氧的喷射氣體而實施鋼帶的 直接火焰衝擊，在此噴射氣體中混合有氣態或液態燃料。 另一個發展結果提出鋼帶的感應式加熱係發生於惰氣 (保護氣體）中。 根據步驟h)的鋼帶移除可以包含捲繞該鋼帶。根據申

的平坦度及/或溫度（後者較佳地是藉由溫度掃描器而實 施），藉此監控鋼帶的品質。 可以藉由一個程序模組控制或調節鋼帶通過鋼帶處理 設備、特別是與區域有關的鋼帶加熱、矯直滾子的調整、 及/或特別是與區域有關的冷卻的行進速度。 在通過鋼帶處理設備期間，鋼帶可藉由驅動器在至少 一些區段上被維持在預定好的鋼帶張力下。這可以特別應 用於在加強冷卻區段的區域内。 為了確保鋼帶在驅動器中對中地行進，在滾子矯直單

有所不同。現在存在有過去數十年間所新近研發出的數種 高強度與超鋼強度類型的鋼’其特性可以經由特殊的報乳 及/或冷卻策略加以調整。用於此目的之一種適合方法是在 觀軋之後以高冷卻速率對鋼帶進行淬火，接著將鋼帶再度 加熱至相位變換溫度以上的溫度。 能夠以此方式製造的標準QT鋼（Q表示經淬火，τ表示 經回火)已經在重鋼板架上製造出來。然而，它們也可以在 熱寬鋼帶軋鋼機上實質上更加經濟地被製造出來。 而且，可以更加可靠地在熱鋼帶軋鋼機上製造出具有 較低溫度與厚度公差以及鋼帶平坦度之較薄、超高強度之 鋼▼。因此，可以適當且有利地將一部分的製造從重鋼板 木轉移至鋼帶軋鋼機。 此外，已經有許多新類型的鋼無法在重鋼板架上製 ^在此所提出的方法特別適用於多相位鋼材的群組。藉 由顯著地擴大溫度_時間輪廓的範圍，且特別是藉由中斷冷 郃作用且暫時再次增加溫度之可能性，可以製造出具有目

然後，鋼帶1藉由盤捲器12或13而在捲繞座3中被 捲繞。 然後，鋼帶捲2進入第二程序階段，亦即回火程序。 此處，鋼帶捲2在一開始在一個展開座4中被展開， 且然後被饋送至一個矯直機器14(此矯直機可位於後續爐 子的岫方及/或後方）。在一區域15中，在鋼帶的長度與寬 度上已經發生溫度均等化之後，鋼帶丨進入一爐子Μ。可 能且有利的是將—個綠直機器整合到此爐子16内，類似於

有利地包含一個特別的盤捲器，用以簡單地捲繞高強度 鋼。在此情形中’盤捲器23是所謂的搬運盤捲器。此處鋼 帶捲並不需要被結合至該盤捲器。可樞轉的夾輪（pinch roll) 在轉換至展開位置期間將鋼帶在張力下保持住。因此，捲 、几步驟之後直接以在回火線路（第二程序階段）中的另一程 序接續。 此進步運送也同樣發生於根據圖1的解決方案。 此處’特別的優點是能夠節省具有較高捲繞溫度的鋼 ▼之此量，及能夠將鋼帶捲從第一程序階段快速地進一步 運送至第一程序階段。因此，鋼帶1在爐子16中加熱之前， 已經具有超過周圍溫度T。的溫度。 此外’對於特殊鋼帶來說，也可以倒轉兩個捲盤機23 與22之間的鋼帶’以便能夠使鋼帶具有所需的溫度輪廓或 處理。 較佳地’在較短鋼帶及/或具有足夠尺寸的組件間隔之 隋形中，可以提供將鋼帶1從第一程序階段直接進一步運 迗到第二程序階段，而不需要鋼帶1的中間捲繞及/或後續 攸盤捲器22倒轉到盤捲器23。因此，在此情形中，並未使 15 200914157 用盤捲器23,但是在鋼帶尾端從輥軋機跑出之後，係直接 以低速、或在一開始以高速然後較低的速度實施回火程序。 或者’此種操作態樣可以被應用於鋼帶上，而與其厚 度及速度無關。因此，在一開始並未使用盤捲器23，且也 並未運作爐子。鋼帶被捲繞於盤捲器22上，然後，在盤捲 器22與23之間倒轉地實施回火程序。 鋼帶1沿著軋鋼機的較佳溫度輪廓係對應於圖2而顯 示於圖3中。在此生產線終點處的冷卻方式較佳地為水冷 式或氣冷式。 然而，可以藉由高壓光束而實現冷卻作用。可以藉此 同時貫施鋼帶表面的清潔或除銹。 嫌觀札廠的生產品質通常比回火程序更高，這是因為鋼 帶的輥軋速度大於回火速度的緣故，因此，一種所謂的混 合輥軋操作也有可能以最佳的方式運用軋鋼機。此意謂著 許多鋼帶係捲繞於盤捲器12與13上，同時在回火生產線 上係發生較高強度的鋼帶之進一步加工處理。 因此，根據本發明，鋼帶的製造被進一步實質上分成 兩個程序階段，稍後將藉由一個實施例進一步說明其具有 另外的選擇性步驟。 第一程序階段： 加熱扁塊（厚或薄扁塊）且接著在多架座式熱寬鋼帶乳 鋼機中進行輥軋； •在輸送滾子台上加強冷卻該鋼帶； -通過一矯直機器； 200914157 -將該鋼帶捲繞成一鋼帶捲。

The method of the present invention comprises the following steps: The solution is characterized in that the 200914157 a) heats the flat block to be rolled; b) rolls the flat block into the desired steel strip Thickness; after cooling, the steel strip has a higher temperature than the surrounding c) cooling steel strip; d) winding the steel strip into a steel strip roll; e) unrolling the steel strip from the steel strip roll; f) heating the steel strip; g) cooling the steel strip, and h) removing the steel strip, the steel strip having a temperature higher than the ambient temperature before the heating according to step f). In a preferred embodiment of the invention 'when step d) is carried out, the noodle roll '' stands on a winding seat, wherein 'when the step car is implemented' is located at a distance away from the winding seat One of the unfolding seats = :, : between the steps called e) 'may pass through a heat-insulating steel coil storage, (:: genus adiabatic way to transport the steel coil from the winding seat to the unfolding seat. e) can be continued directly after step d). During cooling, or in accordance with step e) and/or according to the step of cooling = after the steel strip is acceptable - the end procedure. It can also accept a straightening procedure between the unfolding according to step e) and the heating according to step f). It can also be accepted from the straightening procedure between the heating according to step f) and the removal according to step h). The straightening procedure can be carried out by flexing, flexing or otherwise rolling the steel strip around the base. According to a particular embodiment of the invention, the straightening procedure is usually by means of a roller 200914157 bridge straightening machine or a screw-down steel strip flexing roller, or according to the invention on a so-called skin-pass fraine Implementation. During the heating according to step f) above, the steel strip can also undergo a bridging procedure. The strip cooling according to step c) may comprise a layer of stream cooling and a downstream enhanced cooling. The cooling according to step g) may also comprise _ laminar cooling or alternative or additional air cooling. At least a portion of the cooling device can be constructed to cool the region that acts in the region of the entire width of the steel strip. It is also possible to carry out the cooling of the steel strip by means of a high-pressure rod, so that simultaneous cleaning and/or descaling of the steel strip is possible. The strip heating according to step f) may comprise inductive heating. Alternatively, a direct flame impact of the steel strip (10) flame impingement can be achieved. In the latter case, it is preferred that the direct flame impact of the steel strip be carried out by a jet gas containing at least 75% oxygen, preferably almost pure oxygen, in which the gaseous or liquid fuel is mixed. Another development has suggested that the inductive heating of the steel strip occurs in the inert gas (protective gas). The strip removal according to step h) may comprise winding the strip. The removal of the steel strip in accordance with step h) of claim 1 of the patent application may also include a plate-like cutting portion that is pushed away from the steel strip. The steel strip preferably has a temperature of at least 75 〇〇c before cooling according to step c). After the cooling according to step c) and before the winding of 200914157 according to step d), the steel strip preferably has a temperature of at least 25 ° C and at most 400%, preferably between 100 ° C and 300 ° Between C. Another development proposes that after heating according to step f), the steel strip preferably has a temperature of at least 400 ° C, preferably between 400 ° C and 700 ° C. At the same time, the cooling in the step according to step g and the removal of the steel strip according to step h) may preferably have a temperature of at most 2 〇〇〇c, preferably between 25 ° C and 200 ° C. between. The heating of the steel ▼ can occur at different strengths over the width of the strip. Finally, the step can be reversed to the g), for which purpose a winding seat after cooling according to step g) is used. It is also possible to measure the flatness and/or temperature of the steel strip at at least two locations in the strip processing apparatus (the latter is preferably implemented by a temperature scanner) whereby the quality of the strip is monitored. The speed of travel of the steel strip through the strip processing equipment, in particular the zone-dependent strip heating, the straightening of the rollers, and/or the cooling associated with the zone, can be controlled or adjusted by means of a program module. During the passage of the steel strip processing equipment, the steel strip can be maintained at a predetermined good strip tension on at least some of the sections by the drive. This can be used in particular in the area of the reinforced cooling section. In order to ensure that the steel strip travels centeringly in the drive, in the roller straightening unit or in the reinforced cooling section, a strip lateral guide is preferably positioned as it is. Another example of a method for hot rolling and heat treating a steel strip comprises the following steps: 10 200914157 a) heating a flat block to be rolled; b) rolling the flat block into a desired strip thickness; c) Cooling the steel strip, wherein, after cooling, the steel strip has a temperature higher than the ambient temperature; md) winding the steel strip onto the first coiler; e) being interposed between the first coiler and The steel strip between the second reels is inverted, wherein the steel strip is heated between the coilers; wherein the steel strip has a temperature that is more south than the ambient temperature prior to heating according to step e). This method can also be combined with the above examples. Strong use of procedure step a) In the case of materials that do not require tempering, that is, after the step and the toughness characteristics have met the requirements, it can be established only by d) the following further development results proved to be successful The steel strip can be tensioned by the drive before and after the steel strip is cooled. The steel strip can be guided laterally by the action of the transverse guide: this: the guiding action preferably takes place in the region where the strip is cooled, in particular in the laminar cooling zone of the strip. The lateral guiding action of the steel strip can be opened after passing through the head of the steel strip for guiding purposes. In order to occur before the drive, and can be closed again at the end of the steel strip, the temperature of the strip can be measured before cooling and/or heating by means of a low temperature radiant pyrometer. Preferably, the steel 11 200914157 is measured for temperature within and/or after. The manufacturing range of the hot wide strip mill is clearly different from that of the heavy steel sheet. There are several types of high-strength and ultra-steel strength steels that have been developed in the past few decades. Their properties can be adjusted through special milking and/or cooling strategies. One suitable method for this purpose is to quench the steel strip at a high cooling rate after rolling, and then reheat the steel strip to a temperature above the phase change temperature. Standard QT steels (Q for quenching, τ for tempering) that can be manufactured in this manner have been fabricated on heavy steel frames. However, they can also be manufactured substantially more economically on a hot wide strip mill. Moreover, it is possible to more reliably produce a thin, ultra-high-strength steel ▼ with a lower temperature and thickness tolerance and a flatness of the steel strip on the hot strip mill. Therefore, it is possible to appropriately and advantageously transfer a part of the manufacturing from the heavy steel plate to the steel strip rolling mill. In addition, many new types of steel have not been made on heavy steel frames. The method proposed here is particularly suitable for groups of multi-phase steels. By significantly expanding the range of temperature _ time profiles, and in particular by interrupting the enthalpy effect and temporarily increasing the temperature again, it is possible to produce components with virtually any phase combination that cannot be imagined. In addition, a precipitation procedure can be produced, thus in particular introducing a second phase which is a characteristic of modern types of steel. Furthermore, the properties required for higher alloy compositions in conventional manufacturing can be adjusted by the methods mentioned. The advantage of the separate arrangement of the milking and cooling process and the tempering procedure on the other hand 12 200914157 is the flexibility of the method (no need for mixed rolling), the temperature time of the steel strip and the steel itself. Flexible adjustment of coils with coils or from other equipment. It is also possible to cut a plurality of steel coils or plates according to the intended use of the steel strip or by winding (conabiHty). The plate member is preferably cut at a higher temperature, i.e., at a tempering temperature. The advantage of the coupling configuration of the rolling and cooling process and the tempering procedure is that I can save a lot of energy, and it is difficult to coil and bundle the steel strips: in the case of using a special reel with direct transport. To avoid the problem of watch springs (watch_spring). Moreover, in the case of straight-step processing, a quick smash can be achieved. After the step processing or the transportation of the steel strip is taken, it must be mentioned that the steel is affected in the mentioned The microstructure of the belt. In the configuration, it is more likely to be [Embodiment] Figure 1 shows a hot steel strip rolling mill, in which the first yak, the τ belt 1 is at the beginning of the private sequence step (indicated by J) Processing in the process, and processing in any step (indicated by II). ..., in the first program step i. In the first program phase (ie, light drying and cooling program:: (slab) in multi-rack In the milk steel machine, it is only the last three finishing mills, which are not the last three finishing mills, and only the u-rolling base 7, which has been rolled to have a diameter of π 6.

The speed of the cooling of the steel belt! Then j 乂 for example 6m / s. Entering a reinforced cooling system 11, wherein, Ding 13 200914157 according to a preferred embodiment of the present invention, integrated A straightening machine and a drive (shown in detail in Figure 4.) The drive can be placed in front of and behind the reinforced cooling system 11. After the cooling system U is reinforced, another temperature profile and strip flatness can be measured. Preferably, a low temperature radiant pyrometer can be used at these low temperatures. It is also possible to carry out a temperature measurement between the two extruded or driven rollers inside the reinforced cooling system for adjusting the temperature coolant. The steel strip 1 is wound in the winding seat 3 by the coiler 12 or 13. Then, the steel strip roll 2 enters the second program stage, that is, the tempering process. Here, the steel strip roll 2 is opened It is unfolded in a deployment seat 4 and then fed to a straightening machine 14 (this straightener can be located at the rear and/or rear of the subsequent furnace). In a region 15, the length and width of the steel strip After the temperature equalization has taken place, the steel strip enters a furnace. It may be advantageous and advantageous to integrate a green straight machine into the furnace 16, similar to the cooling situation (details are shown in Figure 5). Wherever, the steel strip can be heated in a continuous or inverted mode. Preferably, an oxygen fuel furnace or induction furnace can be used with a heating time between 10 seconds and 600 seconds. Next is the trimming shear 17 or 18. Then, the steel strip! Enter into a laminar steel strip with a cold material system, or enter the human-air cooling line. Following the straightening machine benefits 2 〇. Further, as shown in Fig. 1, next to the winding seat 5 is a plate pushing unit 21 or a coiler 22. It is also possible to configure a strip of steel strip 14 or 20 that can also be imported from the facestock instead of the straightening machine other hot strip mills. Instead of exhibition 14 200914157 opening 4 . Conversely, a direct connection between the two program stages ι and π can be seen in Figure 2 (U is not shown as a complete set I). The final pedestal of the hot-width steel strip steel-laid steel machine (finishing steel rolling machine 7), the steel strip cooling system, and the coiler 12 and 13 of the first program stage k are similarly shown in the drawings. A final coiler 23 is provided for winding a steel strip having a higher strength. In this case, a special coiler can advantageously be included for simply winding high strength steel. In this case, the "winder 23" is a so-called carrying coiler. Here the coil of steel does not need to be bonded to the coiler. The pivotable pinch roll holds the steel strip under tension during the transition to the deployed position. Therefore, the volume, after several steps, is directly connected to another process in the tempering line (second program stage). This progressive delivery also takes place in the solution according to Figure 1. A particular advantage here is that it is possible to save this amount of steel with a higher winding temperature and to be able to quickly transport the steel coil from the first program stage to the first program stage. Therefore, the steel strip 1 already has a temperature exceeding the ambient temperature T before being heated in the furnace 16. temperature. Furthermore, for special steel strips, it is also possible to reverse the steel strip between the two reel machines 23 and 22 in order to be able to impart the desired temperature profile or treatment to the steel strip. Preferably, in the form of a shorter steel strip and/or a component having a sufficient size, it is possible to provide a direct transfer of the steel strip 1 from the first program stage to the second program stage without the need for a steel strip 1 The intermediate winding and/or subsequent winding of the coiler 22 is reversed to the coiler 23. Therefore, in this case, 15 200914157 is not used for the coiler 23, but after the tail end of the steel strip is run out of the rolling mill, the tempering is carried out directly at a low speed, or at a high speed and then at a low speed at the beginning. program. Or 'this type of operation can be applied to the steel strip regardless of its thickness and speed. Therefore, the coiler 23 was not used at the beginning, and the furnace was not operated. The steel strip is wound around the reel 22, and then a tempering process is carried out between the reels 22 and 23 in reverse. The preferred temperature profile of the strip 1 along the rolling mill is shown in Figure 3 corresponding to Figure 2. The cooling at the end of the line is preferably water cooled or air cooled. However, the cooling effect can be achieved by a high voltage beam. It is possible to simultaneously clean or derust the surface of the steel strip. The production quality of the factory is usually higher than that of the tempering process. This is because the rolling speed of the steel strip is higher than the tempering speed. Therefore, a so-called mixed rolling operation is also possible to use the rolling mill in the best way. . This means that many steel strips are wound on the coilers 12 and 13, and further processing of the higher strength steel strip occurs on the tempering line. Thus, in accordance with the present invention, the manufacture of the steel strip is further divided substantially into two program stages, which will be further illustrated by an embodiment which will have additional optional steps. The first program stage: heating the flat block (thick or thin flat block) and then rolling in a multi-seat hot wide steel strip milk machine; • reinforced the steel strip on the transport roller table; Straightening machine; 200914157 - Winding the steel strip into a steel strip. In order to improve the flatness of the high-strength steel strip, it is advantageous to heat the edge of the steel strip before the conventional finishing unit, perform edge shielding in the first cooling section unit, and a straightening machine. At higher winding temperatures, the rapid transport of the coil of steel to the subsequent second stage of the process facilitates the saving of heating energy during tempering. The coils can therefore be transported under adiabatic heat to reduce temperature loss and ensure more uniform material properties. The second program phase: - unrolling the steel strip roll; - if the flatness is insufficient, then the strip is selectively straightened in the straight machine; L is cooled by zone before the actual tempering process Heating, selective equalization of the strip temperature 'is used to make the strip temperature uniform in the length and degree of the strip; a-tempered strip, ie continuously reheated by induction heating, or in the emulsion The heated continuous furnace is actively and continuously re-twisted (for example with an oxygen fuel furnace called the DF! method). · Make - Trim the steel strip; • • Cool the steel strip later; - Re-straighten the steel strip; - Rewind the steel strip into a steel strip roll. The belt can be cut into panels before the furnace, after the furnace, and/or directly before the panel is pushed. In the case of steel belts that are difficult to wind: 17 200914157 The cutting of the plates is particularly advantageous. Cutting at tempering temperatures is advantageous because the steel strip has a lower strength at this time. In the case of thicker steel strips and/or high-strength steels that can no longer be cut, frame cutters, laser cutters or thermal cutters for cutting can be provided. The implementation of the #DFI Oxygen Fuel Method (Direct Flame Shock) for tempering oxygen furnaces contains a special furnace in which (almost) pure oxygen is mixed instead of air and gaseous or liquid fuel #, Moreover, the generated flame is directly guided to the steel strip. This not only optimizes the combustion process, but also reduces the emission of nitrogen oxides. The characteristics of the scale are also favorable, or the scale is generated. The name of the seven-second milk operation). The high flow rate of the gas even has a cleaning effect on the surface of the steel strip. For the surface quality of the steel strip, this kind of addition is particularly advantageous by this method and the induction heating method has High heat density as good as efficiency. Instead of arranging the cooling section and the line correction successively in the 帛 or second program stage, the machine, the straightening machine and the strip cooling can also be accommodated and combined; The use of a continuous roller as a water squeezing roller and thus a cold part effect, because the steel strip is formed, the lateral bending and the flatness of any steel strip are directly eliminated. Cooling = fruit can be as uniform as possible on the width of the steel strip. With the help of the continuous machine mold, the sniffer can be individually adjusted according to the temperature of the steel strip and the quality of the material, so that the surface of the steel strip can be prevented from being excessively stretched. “The tension is not increased, and the front and rear of the cooling section unit = two people can ensure the tension of the steel strip for a long time. Part of the cooling of the steel strip can be carried out in the form of a cooling of the strip zone in order to be able to actively influence the temperature of the 18 200914157 knife. The cooling straightening unit is shown in Figure 2 and Figure 2, and the details of these units can be inferred from Figure 4. Any possible combination of straightening, cooling and squeezing can be seen in this figure. Especially in the case of thinner steel strips, the procedure for the threaded insertion of the steel strip head, as shown in Figure 4 (see double arrow), is implemented so that the cooling straightening unit can be raised and pivoted. The straightening rollers can be individually adjusted. ί f As shown in Figure 4, a temperature scanner for the steel strip can be placed before and/or after the common configuration of the straightening machine and cooling. A strip head shape detector (for detecting slip or undulation) can be positioned in front of the device shown. The drive 24, the full cooler unit 25, the straightening rollers 26 and the combined squeeze roller/driver 27 are clearly visible in Figure 4t. Moreover, the nozzles that enhance the cooling system can be seen. In this case, it is also possible to arrange cooling, straightening and driving rollers in a staggered configuration. The amount of weft can be individually adjusted depending on the material of the steel strip and the temperature. Short straight _ cooling unit can rise and twirling. As can be seen from Figure 5, the straightening process T, 14, 16 of the second program stage can also be combined with the apparatus shown. Similarly, the amount of straightening can also be adjusted to suit current steel strip temperatures and strip materials. In this case, the surface effect (higher surface temperature) of induction heating (or direct flame impact in the DFI oxyfuel process) has a positive effect. At the same time, the straightening roller holds the steel strip in place and avoids the flatness of the production, making the most efficient (inductive) heating possible in the long strips of the strip. The steel strip is held by the driving tensile stress 30 before and after the heating-straightening unit. In order to be sure to screw the head number 200914157, the coil 32 and the straightening and carrying roller 3丨 are designed to be vertically adjustable. The use of a cooling straightening unit (Fig. 4) or a heating straightening unit (Fig. 5) is not limited to steel belt equipment but may be provided on heavy steel plate equipment. As shown in Fig. 5, a temperature scanner for the steel strip can be placed before and/or after the common configuration of the short straight machine and the heating. In order to cope with the temperature distribution over the entire width of the strip during the second programming phase during induction heating, a transverse field inductor can be used, which can be displaced transversely to the direction of travel or the direction of transport of the strip. In this way, for example, the edges of the steel strip can be heated more strongly, or less strongly, if desired. By special cooling (zone cooling) or heating at the warm steel strip section or the cold strip section, the equalization of the strip temperature over the length and width of the strip can be selected before heating the strip to the tempering temperature Occurs sexually. This should be especially useful when dealing with steel coils that have not been completely cooled to ambient temperature. In this way, the time it takes for the strip to pass through the strip reel storage can be shortened. The strip coil tracking system (module) and the temperature distribution measured during the unwinding of the strip are used for optimal control of the heating or cooling system. Solder the already-welded (welded-t"rde〇, high wear-resistant roller material for green straight rollers for a longer life and good quality. Temperature scanner and flatness in the production line The meter indirectly monitors the quality of the strip and acts as a means for adjusting and adjusting the signal, such as 1 = production speed, heating power, straightening rollers controlled by a program module, and cooling adjustments. Shown in the slightly modified example - the program phase. Similar to 20 200914157 Figure 1, Figure 6 shows the rear of the finishing train 7, the I-flow strip cooling unit 9, 1〇, and a reinforced cooling system u and Winding seat 3. In this example, 'Enhanced Cooling System U and Steel Belt Refill Unit %• Bud is located at different positions. Drivers 34 and 35 are located in front of and behind the reinforced cooling system U. Here, the steel belt tension It can be held in the reinforced cooling system U for almost the entire length of the steel strip without the steel strip being clamped in the pedestal or coiler system. Therefore, any steel strip undulations that may be produced are taken out, And may reach A cooling effect that is as uniform as possible. To ensure that the steel strip can travel centrally in the drives 34, 35 and/or the reinforced cooling system η, a steel strip lateral guide 331 is particularly advantageously located in front of it. After the drive has been passed through the drive and the cooling system ii has been reinforced, the transverse guides 3 3. i are again opened, so that the flow of water in the laminar cooling system 10 is not hindered. Then, the guide Μ 2 takes over: The guiding task of the steel strip. Similarly, for the end of the steel strip, after the end of the strip has left the finishing train, the guide 33 i is again simple: over the 'to offset any offset of the end of the strip In order to minimize the length of the cooling section, the lateral guides 331 are preferably located inside the steel strip cooling unit 10. Before the individual winding seats 3, the 'continuous rollers 36', 36 2 are growing. After the tension is applied, it sinks into the plane of the steel strip and provides the straightening effect of the steel strip by flexing, flexing or driving the steel core against the base. When flexing the roller 26 (see Figure 4) ) when located inside the reinforced cooling section n BRIEF DESCRIPTION OF THE DRAWINGS [Simplified illustration of the drawings] 21 200914157 The drawings illustrate an exemplary embodiment of the present invention.
