Description
本發明關於申請專利範圍第1項引文的一種由鑄造金特別是鋼連續及不連續鑄造熱滾壓金屬帶的方法。此外本發明還關於申請專利範圍第9項引文的一種實施此方法的生產設備。The invention relates to a method for continuously and discontinuously casting a hot rolled metal strip from cast gold, in particular steel, in relation to the first reference of the patent application. Further, the present invention relates to a production apparatus for carrying out the method of the ninth application of the patent application.
利用習知用於作水平鋼帶鑄造的方法，可將不同種類的鋼熔融物鑄造成接近終尺寸，其金屬帶厚度小於20毫米。在此特別可有利地製造含高量C、Mr、Al及Si的輕構造鋼。Using conventional methods for horizontal steel strip casting, different types of steel melt can be cast to near final dimensions with a metal strip thickness of less than 20 mm. In this case, it is particularly advantageous to produce lightweight structural steels containing high amounts of C, Mr, Al and Si.
因此，在文獻歐洲專利EP 1 047 510 B1提到一種用於製造滾壓之薄扁平產物的生產方法。依此，在一水平鑄造設備鑄造鋼熔融物，它接近終尺寸，其鋼帶厚度在5mm~18mm範圍，且在達到單滾子架的前滾壓道前在保護氣體大氣下受控制冷卻。A production process for producing rolled thin flat products is therefore mentioned in the document European patent EP 1 047 510 B1. Accordingly, the steel melt is cast in a horizontal casting apparatus, which is close to the final size, and has a steel strip thickness in the range of 5 mm to 18 mm, and is controlled to cool under a protective gas atmosphere before reaching the front rolling passage of the single roller frame.
預滾壓的熱金屬帶在一裝置(它設在前滾壓道下游)中選擇性地受控制冷卻、加熱或保持在一溫度，而熱鋼帶的邊緣作加熱。The pre-rolled hot metal strip is selectively controlled to cool, heat or maintain at a temperature in a device (which is disposed downstream of the front rolling track) while the edges of the hot strip are heated.
在此單滾子架式前滾壓道之後，跟著為一多滾子道或完工滾壓道、及一出口滾子路徑(它具有冷卻裝置以將熱鋼帶冷卻)、以及在上游及下游的捲取裝置(以將熱鋼帶捲取)。After this single roller frame front rolling track, followed by a multi-roller or finished rolling track, and an exit roller path (which has a cooling device to cool the hot steel strip), and upstream and downstream Winding device (to take the hot steel strip).
在多滾子架式完工滾壓道前方的滾子溫度可利用設在前滾壓道後方的裝置冷卻、升高或保持熱鋼帶溫度，選擇性地在沃斯田或肥粒鐵範圍或在從沃斯田鐵變到肥粒鐵的過渡範圍中依標的調整。The roller temperature in front of the multi-roller-type finishing roller can be cooled, raised or maintained at the temperature of the hot strip with a device located behind the front roller, optionally in the range of Worth or ferrite Adjusted according to the standard in the transition range from Worthite to Fennel.
此外，在文獻國際專利WO 2006/06635 A1提到一種製造由輕構造鋼構成的熱鋼帶的方法，該輕構造鋼特別能作冷深拉伸，且其主元素為Fe、Mn、Si及Al，利用鋼帶鑄造法產生的金屬帶坯(Vorband，英：roughed metal strip)先通過一個在保護氣體下的裝置以作均化，並配合選擇性的保持溫度、冷卻或加熱。然後將金屬帶坯作至少一道熱滾壓程序[它包含至少一道批次通過縮減(stich)]，總變形程度至少50%，在最後一道通過縮減後，將熱鋼帶冷卻並捲到鉸盤上，依熱道速度對滾壓速度的比例而定，熱滾壓程序係採線上(inline)方式或解耦方式。In addition, a method for producing a hot steel strip composed of light structural steel is described in the document International Patent No. WO 2006/06635 A1, which is particularly capable of being used for cold deep drawing, and whose main elements are Fe, Mn, Si and Al, a metal strip produced by a steel strip casting method (Vorband, roughed metal strip) is first homogenized by means of a protective gas, and is selectively maintained at a temperature, cooling or heating. The metal strip is then subjected to at least one hot rolling procedure [it consists of at least one batch pass (stich)] with a total degree of deformation of at least 50%. After the final reduction, the hot strip is cooled and rolled onto the reaming disc. Above, depending on the ratio of the speed of the hot track to the rolling speed, the hot rolling program is inline or decoupled.
均化區域須在熱鋼帶的面上造成溫度平衡且將在熱鋼帶內的應力消除，不論溫度位準是保持，或提高或降低皆然。The homogenization zone must cause a temperature balance on the face of the hot strip and eliminate the stress in the hot strip, regardless of whether the temperature level is maintained, or increased or decreased.
滾壓程究竟採線上方式或與鑄造程序解耦(脫鈎)的問題，主要依鑄造及滾壓時不同的速度而定，其中材料的再結晶性質也有關。The problem of whether the rolling process is off-line or decoupled (de-hooked) from the casting process depends mainly on the different speeds of casting and rolling, and the recrystallization properties of the material are also related.
在鑄造程序時，在熔融目的範圍中滾相中的材料與凝固材料的進一步程序驟經由「鑄造鋼帶」直接連接。In the casting process, the further steps of the material in the rolling phase and the solidified material in the range of melting are directly connected via a "cast steel strip".
此「鑄造鋼帶」經一運送路徑送到進一步加工級。這些進一步的程序步驟可為：整直(Richten)、滾壓、切割及捲取[用鉸盤捲取(鉸捲)(Haspeln)、捲成帶捲(Coilen)]，由於一鑄造設備的這些及其他元件，在鑄造鋼帶中會造成拉力及物料流的波動。如果這些擾動沿液態鋼的方向繼續，則會造成鑄造作業干擾及對鑄造鋼帶有負面影響。舉例而言，如厚度變動、流量過量(berstrmung)、邊緣皺縮、及鋼帶或鋼液流撕裂的情事。This "cast steel strip" is sent to a further processing stage via a transport path. These further procedural steps can be: straightening, rolling, cutting and coiling [Haspeln, coiled (Coilen)], due to a casting device And other components, in the cast steel strip will cause fluctuations in the tension and material flow. If these disturbances continue in the direction of the liquid steel, it will cause interference in the casting operation and have a negative impact on the cast steel. For example, if the thickness changes, the flow is excessive ( Berstr Mung), edge shrinkage, and tearing of steel strip or molten steel.
本發明的目的在提供一種在一鋼帶鑄造設備上製造熱鋼帶的方法，以及一種具有捲取裝置或推疊裝置的鋼帶鑄造設備，使得在鑄造程序後的程序步驟對於所要製的鑄造鋼帶就其品質及材料性質而言沒有不利影響，且該鑄造鋼帶在鑄造程序後可切分成預定的尺寸單位，這種尺寸單位可運送或儲存，例如堆疊的金屬板或鋼帶捲(Bundo)[帶捲(coil)]。It is an object of the present invention to provide a method of manufacturing a hot steel strip on a steel strip casting apparatus, and a steel strip casting apparatus having a take-up or push-up apparatus such that the program steps after the casting process are for the desired casting The steel strip has no adverse effect on its quality and material properties, and the cast steel strip can be cut into predetermined unit sizes after the casting process, which can be transported or stored, such as stacked metal sheets or strips ( Bundo) [coil].
這種目的依本發明係利用申請專利範圍獨立項第1項或第8項的特徵達成。This object is achieved according to the invention by the features of item 1 or item 8 of the independent scope of the patent application.
依此，依申請專利範圍第1項的特點，該利用鋼帶鑄造作業的鋼帶熱通過一個在保護氣體大氣下的第一均化區域以使組織構造均化，配合著將鋼帶坯的溫度選擇性地保持、降低或提高，以及配合驅動器、捲帶器(Looper)、驅動器誤差。然後將鋼帶坯通過一溫度調整裝置，以選擇性地將鋼帶溫度保持、降低、或提高。在進一步過程，該鋼帶坯在一熱滾壓程序(它包含至少一道批次通過縮減)將厚度縮減少於49%，然後將該鋼帶坯在它呈熱鋼帶方式從後續的鋼帶坯切斷之前，通過一第二均化區域。Accordingly, according to the feature of the first item of the patent application scope, the steel strip using the steel strip casting operation passes through a first homogenization zone under the protective gas atmosphere to homogenize the structure of the steel, and cooperates with the steel strip. Temperature is selectively maintained, reduced or increased, as well as with driver, taper, and driver errors. The steel strip is then passed through a temperature adjustment device to selectively maintain, lower, or increase the temperature of the steel strip. In a further process, the steel strip blank is reduced in thickness by 49% in a hot rolling process (which includes at least one batch reduction), and then the steel strip is in a hot steel strip from the subsequent steel strip Before the blank is cut, it passes through a second homogenization zone.
在第一均化區域中使用一氬/CO2 -氮混合物當作惰化氣體。在第一均化區域中將溫度保持在900~1000℃範圍，或將溫度降了200℃，或將溫度升了250℃。An argon/CO 2 -nitrogen mixture was used as the inerting gas in the first homogenization zone. The temperature was maintained in the range of 900 to 1000 ° C in the first homogenization zone, or the temperature was lowered by 200 ° C, or the temperature was raised by 250 ° C.
為了使材料能彎成一鋼帶捲(帶捲)，它須具有適當組織構造，俾能在所發生之拉應力及壓應力時變形。In order for the material to be bent into a strip of steel strip (tape), it must have a suitable texture to deform the crucible and compressive stresses that occur.
這種組織性質可利用該至少一道滾壓過程用一道通過縮減達到49%的變形程序。This tissue property can utilize the at least one rolling process with a deformation process that achieves a 49% reduction.
利用這種變形程序，使材料再結晶作用在隨後之第二均化區域中發生，此時所得之熱鋼帶作一道至少在邊緣區域達成的再結晶作用，其中將熱鋼帶的溫度保持，或降低或升高。With this deformation procedure, the recrystallization of the material takes place in the subsequent second homogenization zone, in which case the resulting hot steel strip acts as a recrystallization at least in the edge region, wherein the temperature of the hot steel strip is maintained, Or lower or raise.
在該第二均化區域(它設在第一滾子架下游)中材料可再結晶，且因此可吸收拉伸應力及壓應力，這種再結晶進行方式特別適合輕構造鋼，其凝固區域可以很大，換言之，從熔融物開始凝固起到完全凝固為止有一多少有點大的「溫度窗孔」，且具有與此窗孔有關的零固體溫度，或零韌性溫度。In the second homogenization zone, which is arranged downstream of the first roller carrier, the material can be recrystallized and thus absorbs tensile and compressive stresses. This recrystallization process is particularly suitable for light structural steels, the solidification zone It can be very large, in other words, there is a somewhat large "temperature window" from the solidification of the melt to complete solidification, and has a zero solid temperature or zero toughness temperature associated with this window.
在鋼帶坯通過第二均化區域後，從熱鋼帶被送到一切斷區域，其工作速度與滾壓或運送速度同步。在鋼帶坯中以預定長度切斷，並在一捲取設備中捲取成一鋼帶捲。After the steel strip passes through the second homogenization zone, it is sent from the hot strip to a cut-off zone where the operating speed is synchronized with the rolling or transport speed. The steel strip is cut at a predetermined length and wound into a coil of steel in a take-up apparatus.
但熱鋼帶的切斷過程而可在該熱鋼帶離開第二均化區域後就已達成。如此，該切成一定長度的熱鋼帶利用適當的運送裝置送入一堆疊裝置，並在該處呈鋼板的形式堆疊。However, the cutting process of the hot steel strip can be achieved after the hot steel strip leaves the second homogenization zone. Thus, the hot-steel strip cut to a certain length is fed into a stacking device by means of a suitable conveying device and stacked in the form of a steel sheet there.
在本發明的方法一特點，該鑄造程序與滾壓程序解耦(脫鈎)。In a feature of the method of the invention, the casting program is decoupled (unhooked) from the rolling program.
如此有一優點：第一、鑄造速度可選設成依熔融物凝固程序過程而定，第二、熱滾壓程序可在一定熱鋼帶溫度達成，直到達到預定變形程度為止。There is an advantage in this way: first, the casting speed can be set according to the melt solidification procedure, and the second hot rolling procedure can be achieved at a certain hot strip temperature until a predetermined degree of deformation is reached.
在本發明方法的另一特點，在將組織構造均化的第一程序後，將鋼帶坯的運送速度利用物料流調節單元改變。如此可防止在製造程序內隨後的程序過程的干擾對鑄造過程及鑄造鋼帶有不良影響，且舉例而言，可防止造成厚度變動，流量過量，邊緣皺縮，及鋼帶或鋼液流撕裂的情事。In a further feature of the method of the invention, the transport speed of the steel strip is changed by the material flow conditioning unit after the first procedure of homogenizing the tissue structure. This prevents the subsequent process disturbances in the manufacturing process from adversely affecting the casting process and the cast steel, and for example, prevents thickness variations, excessive flow, edge shrinkage, and stripping of the steel strip or molten steel. Cracked situation.
依申請專利範圍第9項的特點，用於實施本發明的設備由一個習知的鑄造機構成，它的下游設一個在保護氣體大氣下的第一均化區域以改變所鑄造之鋼帶坯的組織構造，在此區域中，鋼帶坯溫度可選擇性地保持、降低、或升高。According to the features of claim 9 of the patent application, the apparatus for carrying out the invention consists of a conventional casting machine, which is provided with a first homogenization zone under the atmosphere of the shielding gas to change the cast steel strip. The tissue structure in which the temperature of the steel strip can be selectively maintained, lowered, or increased.
第一均化區域下游設有一第一溫度調整裝置以選擇性地將鋼帶坯的程度保持、降低或升高。A first temperature adjustment device is provided downstream of the first homogenization zone to selectively maintain, lower or raise the extent of the steel strip.
沿鋼帶坯的運送方向看，在第一溫度調整裝置下游設有一第二溫度調整裝置，其中在第一及第二鋼帶坯運送元件之間設入一物料流調節裝置，第二溫度調整裝置中將鑄造鋼帶調至適當滾壓溫度，而且係選擇性地藉保持鑄造鋼帶的溫度，降低溫度或升高溫度達成這種調整。Viewed along the direction of transport of the steel strip, a second temperature adjustment device is disposed downstream of the first temperature adjustment device, wherein a material flow adjustment device is disposed between the first and second steel strip conveyance elements, and the second temperature adjustment is performed. The cast steel strip is adjusted to the appropriate rolling temperature in the apparatus and is selectively achieved by maintaining the temperature of the cast strip, lowering the temperature or raising the temperature.
第二溫度調整裝置下游設一第一滾子架，其中用至少一道通過縮減將鋼帶坯以適當溫度使厚度縮減小於49%。在一第二均化區域(它設在第一滾子架下游)中，鋼帶坯此時呈熱鋼帶的形式，在700~900℃的溫度作一道再結晶作業，特別是在熱鋼帶的邊緣區域中作再結晶，因此材料可吸收在捲取或堆疊時發生的拉力、壓力及塑性變形而不會對組織構造有影響。A first roller frame is disposed downstream of the second temperature adjusting device, wherein the steel strip is reduced in thickness by 49% at an appropriate temperature by at least one reduction. In a second homogenization zone (which is located downstream of the first roller frame), the steel strip is in the form of a hot steel strip, which is subjected to a recrystallization operation at a temperature of 700 to 900 ° C, especially in hot steel. The edge region of the belt is recrystallized so that the material absorbs tensile, compressive and plastic deformations that occur during winding or stacking without affecting the texture of the tissue.
最後，在第二均化區域下游設有一切斷裝置，它以一種工作速度操作。此工作速度與熱鋼鋼帶運送裝置的運送速度同步。在切斷裝置中，此連續送到此裝置的熱滾壓鋼帶在切斷後捲取起來或呈鋼板的形式堆疊。Finally, a shut-off device is provided downstream of the second homogenization zone, which operates at a working speed. This working speed is synchronized with the conveying speed of the hot steel strip conveyor. In the cutting device, the hot rolled steel strip continuously fed to the apparatus is taken up after being cut or stacked in the form of a steel sheet.
