Description of the Invention: [Technical Field of the Invention] The present invention relates to a garment garment 1 for manufacturing a thin hot steel strip, which is cast by a casting roller using an endless program, having a casting machine, at least - a rolling track, and a majority of the completed rolling frame; a steel plate is cast in the casting machine, and the rolling line is connected downstream of the casting machine, and the rolling line is like a > ^ T 4 溥 steel plate using the casting process The primary hot work is rolled, and the finished rolling frame is set in the rear direction along the connecting direction of the steel shovel. In this range, the steel strip can be rolled to the thickness by the welcoming roller. In addition, there is a method of manufacturing a thin hot steel strip using an endless program for casting rolls. [Prior Art] This type of equipment is known in the form of a thin steel sheet/thin steel strip casting rolling apparatus, which is named CSP equipment. If the rigid joint between the continuous casting equipment and the rolling track and its temperature operation through the entire equipment are perfect, they can effectively produce hot steel strip. In European patent EP 0 286 862 A1 #OEP 0 771 596 B1_ by casting heat, endless rolling. Here the casting program is directly coupled to the rolling program (koppeln, English: CC) Uple). In the reaming plate (this (10), English: caps (10), the endless steel strip is cut off with a shearing tool. The method of continuously manufacturing the steel strip in the case where the town equipment is combined with the rolling equipment is described in EP 〇 415 987. B2 and Ep 〇 889 762 bi. Another technique is to roll individual steel plates or individual steel strips. When making the steel strips discontinuously rolled, the casting is made into a chapter of "Zhang Yuxing, decompression work decoupling.

Here, the powdery shell material is compressed under high pressure. In the HIP method, 'prefabricated in a conventional manner—the roller core is pharogufl or forged (schmieden, and then the shell material is combined with the core. For &, the core and powdery shell material in special 4 201105438 ' The HIP device is heated and compressed at very high gas pressures (acting in all directions) and at high temperatures (about 1100 〇c) above its flow limit. However, such rollers have not been used for finishing rolling so far. Used in the front range of the Roller stage. The reason is that these rollers are easily damaged, and when the rolled steel strip ends or other disturbances cause surface damage or thermal cracks, the roller is scrapped in advance. This makes it substantially uneconomical or even impossible to use them in a rolling frame. L Lean content] It is therefore an object of the present invention to provide a method and apparatus for manufacturing a thin hot steel strip in the above manner, so that the roller has Higher power and higher economy. This object is achieved according to the invention by using a device for manufacturing a thin hot steel strip, which is manufactured by a machine, at least one rolling track. And a majority of completed rolling frames; a steel sheet is formed in the casting machine, and the rolling passage is connected downstream of the casting machine, in which the thin steel sheet is rolled by the primary heat of the scale forming process Li, the two press frames are arranged in the rear direction along the conveying direction of the steel strip, in which the steel strip can be rolled by the working roller, wherein the m rolling working roller has a wear-resistant roller surface This is achieved in particular by the fact that the surface of the roller is formed by a layer of material that is worn out of the material;; the second layer of the wear-resistant layer is powdered in a conventional manner - in this case, the wear-resistant layer It should be manufactured by using: pressurization method). u, 4 pressure This wear-resistant layer can also be composed of a variety of metals, composite materials (5 201105438 called "Cermets"). According to a feature of the invention, the working roller is designed in the form of an HSS roller or a semi-HSS roller (high speed steel roller, semi-high speed steel roller). Here, all of the rollers of the at least one rolling track preferably have a wear-resistant roller surface. The method for manufacturing a thin hot steel strip by casting rolling using the method of casting rolling is characterized in that the working roller of the finished rolling frame of the household is equipped with a roller surface of a wearer, in particular, a layer having a wear resistant material. By. Here, in order to ensure the exact rolling procedure and the long service life of the roller, J moves up the gap between the working rollers before the steel strip enters in the range of the finished rolling frame. After the steel strip enters, the rolling gap will be rolled to the nominal value. Here, the roller gap moves up __, the British amount up) and reaches the value of -, at this value, in the case of a true rolling thickness, the rolling roller does not cause damage to the working roller. . Correspondingly, the rolling gap can also be moved from the nominal value to a larger value at least in the finished rolling frame in the steel strip exit. , - It is advantageous to roll the steel strip in the finished rolling road to a thickness of the finished steel strip between ~1.5 mm. The basic idea of the invention is that one is the one that has been used so far - for the use of the binding roll 0 in the endless program and the failure to break the finish rolling, the use of the worn work roller is thin The steel belt work rolls are previously known, but due to the roller load report, this type can be used in the completion rolling. ° k is not yet these measures This point is achieved by using the above-mentioned method of material processing, 201105438 to ensure even if the rolling load is completed. The order "will not be used as a roller. In the case of the endless rolling of the present invention, the failure of the rolling house can be avoided. This: The working roller having the wear-resistant roller surface of the two guides is even after the completion of the rolling. It can be used. Here, the rolling operation lasts for a long period of time (a lot of hours) without having to penetrate (Einfadeln) and wear out A=deIn on the rolling road. The above special measures can be started and ended (for example) Rolling the steel strip to a larger final thickness to be rolled accurately.) "To keep the working roller load of the finished rolling armor low. Here, bring out the loss" (Ausbdngungsverlust, English 1 is smaller, because the length of this loss is small compared to the total length of the endless rolled steel strip. In the case of endless rolling, use wear-resistant working rollers (especially HSS roller, PM roller), the economical manufacturing method of this thin steel strip is particularly advantageous. The number of roller replacements is very small, so there is very little interruption in the scale work. Therefore, the rolling program or casting sequence can be extended while the steel strip The contour is better because even at the rear is rolling The wear of the work rolls is also small. The productivity of the entire equipment can be increased by the rolling program or the scale sequence extension. The embodiment of the present invention is shown in the drawings. [Embodiment] FIG. A device for manufacturing a thin hot steel strip (1). The steel strip is manufactured by a cast-roll endless process. For this purpose, a binding machine 201105438 (7) is provided in which at least one thin steel sheet is cast. Downstream with a rolling track (4) (5) β in the rolling track (4) (5) using the primary heat of the orthodontic process (Ρ h itz h 英 渐 渐 渐 渐 渐 渐 渐 渐 渐 渐 渐 渐 渐 渐 渐 渐 渐Steel belt mm pressure channel (4) m rolling road (5). The material rolling road (5) has a majority of completed rolling frames (7), which are located in a rear area of the rolling road (4) (5) (6) (in the rear direction seen in the transport direction F). Here, the steel strip (1) is rolled to a final thickness, which is preferably in the range of 0 5 mm to 15 mm. The steel strip is rolled at completion. In the frame (7), the working rollers (8) are used, which are supported by the roller holding roller. Here, the important point is that the working roller (8) of the finished rolling frame (7) is wear resistant. Roller table®, the roller surface is formed in particular by a layer of wear resistant material* although one of the above-mentioned methods is known to the prior art, but they have never been used for steel strips (1) For the roller with wear-resistant surface, refer to M-Andersson et al., “introducti〇n 〇f ― 抓 (五)比比...... chill and high speed Steel rells in Europen hpt strip mills” (See Ironrnaking and stellmaking, 2004, Vol. 31, ν〇·5· 383 pages, and EP 1 365 809 B1 (especially in paragraph [0014]). The HIP method is described in detail in CH-HIP-L6sungen fur Werkzeuge und Formen " by Ch_ Willems et al. (in '' Stahl', 1998, Vol. 6, pp. 38-40). Metal-ceramic composites (also known as “Cermets”) is used as a wear-resistant material in many components due to its high hardness and fracture toughness. This feature is also used in this 8 201105438. This wear-resistant work roller should be rolled in hot steel. It is used in all the ink rollers of the relocation road, so it is used even in the front rolling road (4) (the latter is used in the previous technology). a Here, the flow of the program should be such that the rolled steel strip is pressed. The failure or damage of the end or working roller is avoided by the following measures: In the case of the product size (thicker finished steel strip) to be produced, the open roller gap can be used to wear a or the steel head can be inserted. The steel strip is inserted into the finishing roll (4)' to adjust the thickness of the roller gap to the target thickness to be strictly produced, and should be adjusted to a value below 丨·5 mm. In addition, there is an endless rolling program (En(U〇S_) (4) For the long strip section of the steel strip (Filettei l) Most of the tapes are used. The steel strips can also be punched out with a larger end thickness gap. The main difference between the device shown in 氓jianzhong and the figure is: here is a kind of tight wave Pressure channel, but it also has a rear part in the conveying direction f called 'working roller with a wear-resistant roller surface in the latter part. In this (4) executable - endless rolling program or Batch operation. Various conventional components of the device for making thin hot steel strips are explicitly used in the drawings 'but here they are not essential points. Pass = as long as special attention is paid to an induction furnace (9) and a holding furnace (10) Use (Form #, in addition to - cooling channel (1)), there is a Chin (2) at the rear to take the finished steel strip into a coil (13). As explained above, in the completion The work 201105438 used in the rolling frame (7) is a roller (8) which is a conventional roller or a Cermet roller body and is also vulnerable.

In particular: the disturbance is caused by a large steel strip edge (edge_d—) or a bulge due to edge wear, for example. In addition, the surface quality of the roller and the surface quality of the steel strip also significantly affect the rolling 弋 length, which is not only related to the crude sugar content, but also, for example, due to the embossing of the roller surface (Abdruck). High wear occurs in thin steel strips, and it is particularly noticeable in the rolling broadband temple wear effect. In the conventional hot steel belt rolling road, the steel strip end is rolled down or other rolling burrs are also many. Therefore, this technique: that is, the use of a wear-resistant working roller (even in the final rolling frame) for thin steel strip rolling is particularly advantageous in an endless steel plate apparatus. This endless technique avoids rolling plague, and The worn-out roller improves the product quality' and extends the length of the rolling program. This combination of direct applications (in the case of a small amount of energy supply, townmaking and then rolling) and the extension of the casting sequence make the above technique particularly economical.
