Description of the invention (I) [Background of the invention] 1 · Field of invention The present invention is like a manufacturing equipment for manufacturing hot-rolled flat products. The manufacturing equipment includes a roll group composed of a plurality of roll stands, and an output roller table, wherein the output roller table has a device for cooling the hot strip, and the coils for winding the strip are arranged from and subsequently Take the machine. 2. Description of the related art Rolling equipment used to manufacture hot-rolled strips is usually constructed and operated today so that the deformation in each seat occurs in a Vostian state; this means that the rolling in each roll seat is guaranteed The temperature is higher than the GO S line in the iron-carbon phase diagram. The change of the K structure on the cooling extension frame or coil material to the shaping temperature * is only after the last rolling pass. In order to obtain the final structure of fine grain size, the cooling should be as close as possible to the GO S medium . As for the low-alloy carbon steel, in order to be able to roll by the method described above, the final rolling temperature *, that is, the temperature in the final roll seat in the roll group is about 8 4 0 ° to 9 2 0 υ, depending on the carbon content. The final rolling temperature is maintained by changing the speed of the final rolling plus K, where the driving power of each roll stand can control the natural cooling of the strip in the L roll group of the car and supply heat. This method can be used without any problem for those with a strip thickness greater than the minimum strip thickness, and the latter depends on the type of rolling roller group, and the value is about 1.3m. If the wall thickness is reduced below this minimum thickness, the required rolling speed can reach a value of about 12 meters per second at the head of the strip; the high speed * makes the strip follow the roll seat On the subsequent roller table, M control can no longer be added at the free output end. -3- This paper scale is applicable to the Chinese National Standard (CNS) Α4 specification (210X297mm) (please read the precautions on the back before filling in this page), 4. Order 316858 a7 B7 5. Description of the invention (/) For the problem discussed above, the trend is to develop a thinner final thickness; this means that the trend is to lower the final rolling temperature and reduce the rolling speed. These rolling processes have become known as ferrite iron rolling because it occurs at a temperature lower than the GOS line, that is, within the crystal lattice range of α and 7 phase mixing, or below the ferrite iron range. In the GPS line. According to a preferred method, rough rolling is performed in the range of Vostian, and is rolled to an equal thickness in the range of 2 to 8m, while finishing rolling is performed in the range of ferrite iron, and the rolling is less than 1 · 3 Thin final thickness. Between these two process stages, the rolled billet must be cooled from the final rolling temperature in the Vostian iron range to the rolling temperature in the fertile iron range. This means a cooling range from 840C to 9 2 0 t to 60 0 ◦ D to 7 8 Ot: temperature range. The final rolling temperature after the second deformation stage is also in the range of 600 ° C to 780 ° C, so after winding around the coil, it is around the amount of recrystallization of the structure. A structure was created, which facilitated the use of the product without the need for further cold deformation or heat treatment. Printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs (please read the precautions on the back before filling out this page) An essential condition for obtaining good results is the cooling of the range from the Vostian iron range to the fertilized iron range , When maintaining a minimum cooling time. This minimum cooling time must be maintained in order to allow the transition from Vostian iron to fat iron to be fully carried out. Depending on the selected temperature K and alloy composition, the minimum cooling time for entering the first ferrite transition is about a few seconds to a few minutes. For hot-rolled wide strips, the above-mentioned process is achieved in the traditional roll set -4- This paper standard is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) Employee consumption cooperation du printing package of the Central Bureau of Standards of the Ministry of Economic Affairs 3l ^ S58 at ---- V. Description of invention (>) It is very difficult. The transformation from the Vostian iron range to the ferrite grain iron range should be carried out in the thickness range of 2nnD to 8rai, that is, the rolling stock is approximately in the thickness range of the middle of the traditional finishing stand. Since the strip travels from one to the next in the middle of the finishing roll group, it takes only a few seconds. In principle, the cooling can be achieved, but the time required for the transformation cannot be achieved. Therefore, in the rolling roll group of Chuan Chuan, it is impossible to roll the ferrite grains according to the above-mentioned method for rolling hot strips. [Summary of the Invention] Therefore, the main object of the present invention is to provide a manufacturing apparatus for rolling hot-rolled strip, in which the above-mentioned various defects can be eliminated. In addition, with the desired limitation on the output speed, the optional part of the strip thinning should occur within the range of fat iron. According to the present invention, at least the first roll stand in the roll set is a reversible stand. At least one turn will be placed before and after the reversible seat. A controllable cooling unit is provided between the reversible base and the converter in front of it. One of the manufacturing equipment constituted by the present invention can operate within the scope of Vostian Railway, just like the situation in traditional equipment. For this purpose, the rolling stock is supplied from a roughing roll set or a sheet-setting machine * which usually has a thickness of 5 Om to 100 m, heated in a furnace to about 1 1 OOC, and then contains one or more In the reversible roller set or Steckel roller set, K is rolled by adjusting one or several seats of the roller set; then * the rolling blank 'material follows the Sturkel roller set It is rolled in a Styker or converter. The size of the reverse paper applies to the Chinese National Standard (CNS) A4 (210X297mm) (please read the precautions on the back before filling in this page). Order the printed consumer i, invention description (1- -) After the anti-Sticker roll group, the strip is pulled from the Stalker furnace and rolled in one or several seats of the Stalker group to a thickness of about 5ηππ to 15rai, and then wound on the entrance side Stryker. Here, the temperature of the strip is still higher than 8 5 Ot. The strip was unrolled from the inlet side M and its furnace at this time, and rolled to a thickness of about 1 m in the sturdy K and the remaining roller sets, and then the strip was wound by the coiler. According to another feature of the invention, a heating element may be provided between the Stryker roll group and the remaining rolling and forging groups, K to ensure that the strip is not cooled excessively. It is also possible to arrange a cooling unit in front of the point where the strip of the roller is wound on the upper side of the Stryker, where the cooling unit cools the strip with a thickness of about 5 to 15 ° C to a temperature below 8 5 0C. After the ferrite iron is transformed, the strip can be rolled into a strip with a thickness of about 1 nra in the STICK roll group and the remaining roll groups. The heating unit after the Sturker roll group and in front of the remaining roll groups may be omitted if all seats of the roll group are reversible seats. This roll group also makes it possible to roll K exclusively in the range of Vostian iron, or in the range of Vostian iron and ferrite. In this manufacturing facility, only those numbers of reversible seats, that is, those who need to use M to achieve the thickness of the strip that can be wound on the upper outlet side turn, can be adjusted in the first rolling pass. In the second pass, the adjustment is made so that the reversible roll set produces a strip thickness of about 5 mra to 15 iran. Also in this example, before winding the strip onto the converter on the inlet side, a decision can be made by turning on or off the cooling unit: whether the rolling in subsequent rolling passes is in the range of ferrite iron Or within the range of Vostian Iron-6-This paper scale is applicable to the Chinese National Standard (CNS) A4 ^ (210X297mm) (please read the precautions on the back before filling this page), ιτ 316858 A7 B7 Central Ministry of Economic Affairs Printed by Beigong Consumer Cooperative of the Bureau of Standards 5.
