200906504 九、發明說明： 【發明所屬之技術領域】 本發明是有關於一種生產鋼捲的生產線，特別是指一 種生產 2B (No,2B surface finish)及/或 2D (N〇 2D surface finish)鋼捲的連續生產線。 【先前技術】 不銹鋼製程主要可分為煉鋼、熱軋、冷軋三大部份。 『 煉鋼仔到的半成品是扁鋼胚（slab )，經過熱軋產製的是黑 皮鋼捲（black coil)，而黑皮鋼捲再經過退火酸洗後得到的 成口口'?尤疋白皮鋼捲（White coii，也稱為N〇1鋼捲），白皮 鋼捲再經過例如冷軋、退火酸洗、調質軋延及張力整平等 過程後即生產出可供出貨之用的產品鋼捲（其中，僅經 過冷軋與退火酸洗過程製得的稱為2D鋼捲，再經過調質軋 延及張力整平過程所得到的成品則稱為2B鋼捲）。 參閱圖1，傳統的不銹鋼冷軋製程是一種分段式的生產 I 線，包含獨立設置的一座鋼捲準備設備11、一座冷軋設備 12、一座退火酸洗設備丨3、一座調質軋延設備14，及一座 張力整平設備15。 邊鋼捲準備設備11是在將白皮鋼捲1〇〇解捲成鋼帶 400後，於該鋼帶400的頭、尾端分別銲接上一段導料帶， 再盤捲成待作業鋼捲200;該冷軋設備是一座二十重冷 軋機（20High Cold Rolling Mill )，用以將鋼帶4〇〇往復冷 軋成預定的厚度；該退火酸洗設備13是對鋼帶4〇〇進行熱 退火，及酸洗去除其表面的鏽皮；該調質軋延設備14以拋 5 200906504 光輥（圖未示）轉印提高酸洗後的鋼帶400表面光澤；該 張力整平設備15對調質後的鋼帶進行整平、調整板形。 此等分段式的生產線實際生產產品鋼捲3〇〇時，是以 白皮鋼捲100入料，以該鋼捲準備設備u將該白皮鋼捲 100展成鋼帶400，並在鋼帶400頭、尾端各銲接長度在 8〜1〇米的導料帶，以減少後續以冷軋設備12進行冷軋時穿 帶盤捲所造成的重量損失；銲接導料帶後再將銲接有導料 广 帶的鋼帶400盤捲成待作業鋼捲200,以輸送至該冷軋設備 12進行冷乳。 接著作業人員會將待作業鋼捲200穿帶至冷軋設備12 中’而使導料帶導引鋼帶400在二十重冷軋機中多道次往 復軋延，直到軋延成預定厚度後，退出冷軋設備12並再度 盤捲成待作業鋼捲200後，預備輸送至退火酸洗設備13進 行退火酸洗作業。 然後’作業人員將待作業鋼捲200再以導料帶穿帶導 引鋼帶400進入退火酸洗設備13中，先將導料帶切除再進 行銲接。接著進行熱退火，再以酸液酸洗掉鋼帶400表面 的鏽皮，接著退出退火酸洗設備13並再度將鋼帶盤捲成待 作業鋼捲200 —此時產得的待作業鋼捲200即為2D鋼捲， 可視下游業者的需求，進行第一次的出貨。 之後，作業人員繼續將盤捲的待作業鋼捲200穿帶入 調質軋延設備Η中，利用拋光輥（圖未示）轉印光澤於經 過退火酸洗後表面鈍化無光澤的鋼帶400調質，並再度將 調質軋延後的鋼帶400盤捲成待作業鋼捲200，以輸送至下 6 200906504 一設備進行作業。 取後，作業人員將調質軋延並盤捲成待作業鋼捲· 的鋼帶彻再引人張力整平設備15中進行整平、調整板形 ’並裁切掉料及在調質軋延設備14中進行調質軋延時頭 尾未軋延調質到的區域後盤捲，即產製得到產品鋼捲細（ 即2B鋼捲）。 由上述的說明可知，上述產製產品鋼捲300的分段式 生產線’因為每-設備都是獨立且不連續的，所以可以選 擇性的挑選設備進行作業，而具有生產彈性大的優點，但 也因為每-設備都是獨立*不連續的，所以除了必須一再 地將待作業鋼肖2GG解捲成鋼帶進人設備中作f，作業後 又須再度將成品鋼帶盤繞成待作業鋼捲2〇〇，而導致的產出 率低、待作業鋼捲200數量與種類複雜多樣，所需的儲區 大等缺·點，同時，要選擇性的以各獨立設備進行作業，也 會有生產排程複雜、生產時間長而導致生產成本較高的問 題0 為了改善分段式生產線產製產品鋼捲的問題，US M78,899 B1發明案提出一種整合連鑄、熱軋、冷軋製程的 連續生產線，由鋼液入料，產製出薄鋼胚（因連續生產之 故，均無須盤繞成半成品鋼捲）後，經過熱軋、冷軋等系 列製程後，而直接生產出產品鋼捲。 此等由鋼液入料直接產製產品鋼捲的連續生產線雖然 確實可以實際量產產品鋼捲，並且改善了分段式生產線產 出率低、半成品鋼捲數量與種類複雜多樣，所需的儲區大 200906504 ，以及生產排程複雜的問題。但是，此種連續生產線其中 任一設備損壞，或是需要維修保養時，整條生產線就必須 完全停擺，所以會有稼動率（實際作業工時與可作業工時 之比值）低的問題，而事實上，此等由鋼液入料直接產製 產品鋼捲的連續生產線，並未有任何一家鋼鐵業者實際實 施應用。 此外，另有US 6,546，Ή1 B1發明案提出混合±|以 鋼捲，及產品鋼捲（包含2B鋼捲與2D鋼捲）的連續生產 線’由黑皮鋼捲人料’選擇性地使解捲後的黑皮鋼捲通過 --人或複次的整體生產、線，並在每次經過生產線時，選 擇性地使某些設備不作動，而產製不同的產品鋼捲。 此種連4生產線以黑皮鋼捲入料產製產品鋼捲的連續 生產線，確實較須以鋼液人料的連續生產線縮減了部分的 設備’而較符合實際業界生產產品鋼捲所需，但是由於此 種連續生產線在產製不同種類的產品鋼捲時，是採用選擇 性地使解捲後的黑皮鋼捲通過一次或複數次的整體生產線 ，並在每次經過生產線時’選擇性地使某些設備不作動的 生產方式’因此’了仍有設備利用率低以及稼動率偏低 ，而並不符合實際生產的需要外’因為是以黑皮鋼捲入料 ’且生產過程是採用選擇性地通過—次或複數次的整體生 產線’所以還會有產製的產品鋼捲的表面品質較低的問題 〇 因此，就目前的不鏽鋼製程來說，無論是多數業 用的分段式生產線，或是為了改善傳統分段式生產線而提 200906504 出的連續生產線，都仍需要改進以符合實際生產所需。 【發明内容】 因此’本發明之目的，即在提供一種具有高稼動率且 可生產表面品質高的產品鋼捲的冷軋連續生產線。 以現存的鋼捲連續生產線而言，若以未經退火的黑皮 鋼捲直接入料，將會產生達不到普遍要求冷軋軋下率達到 60%〜70%的盲點困難，而欲達到這樣的目標，進入產線的 原料首先必須調整一採用經過退火酸洗後的白皮鋼捲，並 搭配經過適切設計的整體生產線的每一設備，才能在提高 全線的稼動率的前提下，同時提昇鋼捲的軋下率暨表面品 (表面粗糙度Ra—〇·丨2#m)，這是本發明基於實務而產生 的基本概念。 於是，本發明一種以白皮鋼捲產製產品鋼捲的冷軋連 續生產線，依序包含一座解捲電銲設備、一座第一積料調 節設備、一座冷軋設備、一座除油設備、一座第二積料調 節设備、一座退火酸洗設備、一座第三積料調節設備、— 座調質軋延設備、一座張力整平設備、一座第四積料調節 設備’及一裁剪收捲設備。 該座解捲電銲設備具有一台將該白皮鋼捲解捲成—鋼 帶的解捲裝置，及一台在該鋼帶前端銲接前—鋼帶尾端的 銲接裝置。 該座第一積料調節設備具有複數可以相對位移而使該 鋼帶以對應於下一設備之作業速度往下一設備輪送的張I 幸昆裝置。 200906504 4座冷軋備具有複數台成串列式設置以冷軋該鋼帶 成預定的體積厚度的冷軋機。 該座除油設備清除經過冷軋之鋼帶表面的軋延油 該座第二積料調節設備具有複數可以相對位移而使除 油後之鋼帶以對應於下—設備之作業速度往下-設備輸送 的張力輥裝置。 该座退火酸洗設備你库且右 A, . 侑依序具有一台包括禝數溫度區間以 對除油後之鋼帶進行泪jfSF ^艮、卜M、p , #

Description of the Invention: [Technical Field of the Invention] The present invention relates to a production line for producing steel coils, in particular to a 2B (No, 2B surface finish) and/or 2D (N〇2D surface finish) steel. Continuous production line of rolls. [Prior Art] The stainless steel process can be mainly divided into three parts: steel making, hot rolling and cold rolling. 『 The semi-finished product of steel-making is a flat steel slab. After hot rolling, the black coil is produced, and the black-skin steel coil is then annealed and acid-washed. White Coii steel coil (also known as N〇1 steel coil), the white steel coil is produced for shipment after, for example, cold rolling, annealing pickling, quenching and rolling, and tension equalization process. The product steel coil used (the product obtained by the cold rolling and annealing pickling process only called 2D steel coil, and then subjected to quenching and rolling and tension leveling process is called 2B steel coil). Referring to Figure 1, the conventional stainless steel cold rolling process is a segmented production I line, which consists of a separate steel coil preparation equipment 11, a cold rolling equipment 12, an annealing and pickling equipment, and a quenching and rolling mill. Apparatus 14, and a tension leveling device 15. The side coil preparation device 11 is obtained by unwinding the white steel coil 1 into a steel strip 400, and welding a length of the guide strip to the head and the end of the strip 400, and then coiling the steel coil to be operated. 200; the cold rolling equipment is a 20Cr cold rolling mill (20High Cold Rolling Mill) for reciprocating cold rolling of the steel strip into a predetermined thickness; the annealing pickling apparatus 13 is a pair of steel strips Performing thermal annealing and pickling to remove the scale on the surface thereof; the quenching and rolling device 14 is used to transfer the surface gloss of the strip 400 after pickling by a roller of 200906504 (not shown); the tension leveling device 15 pairs of quenched and tempered steel strips are leveled and adjusted. When the segmented production line actually produces 3 turns of the product, the white steel coil 100 is fed, and the steel coil preparation device u is used to form the white steel coil 100 into a steel strip 400, and is in steel. A 400-head, tail-end welding belt with a length of 8 to 1 〇m to reduce the weight loss caused by the coiling of the cold-rolling equipment 12 during cold rolling; welding the belt after welding A 400-gauge steel strip with a wide belt of guide material is wound into a steel coil 200 to be worked on to be conveyed to the cold rolling equipment 12 for cold milk. The pick-up worker will take the steel coil 200 to be carried into the cold rolling equipment 12', and the guide belt guide steel strip 400 will be rolled in multiple passes in the twenty-fold cold rolling mill until it is rolled to a predetermined thickness. Thereafter, after exiting the cold rolling equipment 12 and re-winding it into the steel coil 200 to be worked, it is ready to be sent to the annealing pickling apparatus 13 for annealing and pickling operations. Then, the operator puts the steel coil 200 to be operated and then guides the steel strip 400 into the annealing and pickling apparatus 13 with the guide tape, and then cuts the guide tape and then performs welding. Then, thermal annealing is performed, and the scale on the surface of the steel strip 400 is washed away with acid acid, and then the annealing pickling equipment 13 is withdrawn and the steel strip is again rolled into the steel coil 200 to be operated. The 200 is a 2D steel coil, which can be shipped for the first time, depending on the needs of downstream operators. After that, the operator continues to carry the coiled steel coil 200 to be tempered into the quenching and rolling equipment ,, and transfers the gloss to the surface passivated dull strip 400 after annealing and pickling by using a polishing roller (not shown). Tempering and tempering, and re-rolling the tempered and rolled steel strip 400 into the steel coil 200 to be operated, and transporting it to the next 6 200906504 equipment for operation. After taking it, the operator will roll and temper the coil and wind it into the steel coil to be operated. The steel belt will be re-introduced into the tension leveling equipment 15 to level and adjust the shape of the sheet and cut the material and roll in the quenching and tempering. In the equipment 14, the quenching and rolling rolling delay and the end of the quenching and tempering area are coiled, that is, the product steel coil is obtained (that is, the 2B steel coil). As can be seen from the above description, the segmented production line of the above-mentioned product steel coil 300 is capable of selectively selecting equipment for operation because of the fact that each device is independent and discontinuous, and has the advantage of large production flexibility, but Also, because each device is independent*discontinuous, in addition to repeatedly unwinding the steel xiao 2GG to be rolled into the steel equipment into the equipment, after the operation, the finished steel strip must be coiled again into the steel to be operated. Volume 2〇〇, resulting in low output rate, the number and types of steel coils 200 to be operated are complex and diverse, and the required storage areas are large and lacking. At the same time, it is necessary to selectively operate with separate equipment. The problem of complicated production schedule and long production time leads to high production cost. 0 In order to improve the problem of steel coils produced in segmented production lines, the US M78,899 B1 invention proposes an integrated continuous casting, hot rolling and cold rolling. The continuous production line of the process, which is produced by molten steel, produces thin steel embryos (not required to be coiled into semi-finished steel coils due to continuous production), and then directly produces products after series of processes such as hot rolling and cold rolling. steel volume. These continuous production lines for direct production of steel coils from molten steel feeds can indeed produce steel coils in actual quantities, and improve the production rate of segmented production lines and the complexity and variety of semi-finished steel coils. The storage area is large 200906504, and the production scheduling is complicated. However, if any of these continuous production lines is damaged or needs to be repaired and maintained, the entire production line must be completely shut down, so there is a problem of low utilization rate (the ratio of actual working hours to workable hours). In fact, these continuous production lines for direct production of steel coils from molten steel feed have not been implemented by any steel industry. In addition, another US 6,546, Ή1 B1 invention proposes a continuous production line of 'mixed ±| steel coils, and product steel coils (including 2B steel coils and 2D steel coils) 'selectively made from black-skin steel coils' The coiled black-skin steel coil passes through the entire production, line, or multiple times, and each time the production line passes, it selectively causes some equipment to be inactive to produce different product coils. This continuous production line of the 4 production line with black steel coils and the production of steel coils is indeed more necessary to reduce some of the equipment in the continuous production line of steel and liquid materials, which is more in line with the actual production of steel coils.

By adjusting the conveying speed of the third integrator adjusting device 27, the steel strip 400 after the removal of the ore is given the surface in accordance with the working speed of the tune rolling device 28 Gloss; the steel strip after rolling and quenching and tempering is then placed into the tension leveling device 29 for leveling; the flattened steel strip 4G0 is adjusted by the fourth stock adjusting device 31 to adjust the conveying speed: In the cutting and receiving device 32, the weld bead which is welded to the front end of the steel strip and the front end of the steel strip is cut off, and according to the demand of the shipment, the steel strip is completely taken up and bundled into a product coil 300 (that is, 2B steel) Volume), complete the entire process. 'In addition, it should be noted that when the 2D steel coil is to be produced, it is only necessary to turn off the quenching and rolling rolling β and 28, and simultaneously adjust the speed of the third and fourth stock adjusting equipment 27 ' 3 1 , and The steel strip 400 is directly transferred to the cutting and cutting device 32 for finishing and shipping, that is, the 2D steel coil can be produced in a minimum shutdown state (tempering and rolling equipment 28) to maintain the overall cold rolling continuous production line equipment. Utilization rate. Referring to FIG. 3, the product steel coil 300 is produced by the cold rolling continuous production line of the steel coil produced from the white steel coil according to the present invention, and is compared with the conventional stainless steel cold rolling production product coil 300 shown in FIG. Although the equipment cost of the cold-rolled continuous production line of the present invention is about 16% higher than that of the conventional segmented production line by increasing the serial integration of the various devices, the required operator cost is only 65% of the conventional segmented production line. The rate is 95% of the traditional segmented production line. As for the output rate (output rate - (total output weight / total input weight) * 1 〇〇% 16 200906504) and yield (output weight per unit time) Compared with the traditional segmented production line, the production cost is increased by 6% and 72%, respectively. Overall, the production cost of the cold-rolled continuous production line of the present invention is significantly reduced by 22% compared with the conventional segmented production line. It can be seen from the above description that the cold rolling continuous production line of the steel coil produced by the white steel coil is mainly considering the actual production condition and the equipment demand, and the white steel coil 100 is directly fed, and the series cold rolling is used. Annealing, pickling, quenching and tempering, tension and equalization, and production of product coil 300 (2B/2D cold rolled coil) with high production rate and low production cost in line with actual production cost requirements Compared with the traditional stainless steel cold-rolled segmented production line and the continuous production line proposed in the patents of US6478899B1 and US6546771B12, it has improved the traditional stainless steel cold-rolled segmentation type, such as low output rate during production, steel coil 2 to be operated The number and variety of cockroaches are complex and diverse, requiring large storage areas, complicated production schedules, long production time, and the shortcomings of the continuous production lines proposed in the patents such as US6478899B1 and US6546771B12, which have no practical implementation value because the utilization rate is too low. It does achieve the creative purpose of the present invention.
