Description of the invention (1) [Technical field to which the invention belongs] (Please read the notes on the reverse side before filling out this page) The present invention relates to the setting method of the rolling conditions in the continuous hot rolling method. [. Known technology] Generally, the rolling process of hot-rolled steel strip is formed by the following processes. First, the thick plate is heated by a heating furnace, then the thick plate is heated by a rough calender to form a thin rod, and then the thin rod is rolled by the final calender to form a hot-rolled steel strip. The thick plates, thin bars, and hot-rolled steel strips are collectively referred to as rolling target materials. Traditionally, thin rods rolled by a coarse calender can only be rolled one sheet at a time by different final calenders. This step is called punch calendering. In recent years, the technology of successively joining the tail end of the front thin rod with the front end of the subsequent thin rod between the rough calender and the final calender has been implemented, and the continuous calendering is performed at the final calender. This technique is called continuous calendering. The actual final calendering operations are mixed punch calendering and continuous calendering. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs Next, the method for determining the rolling conditions in the conventional press rolling operation will be described. The host computer system determines the rolling conditions in advance based on information such as the steel type, specifications, dimensions, finished thickness, and finished width of various rolled materials. The material to be rolled is supplied to the hot rolling line later. The terminal computer performs the entry detection of the rolling target material at each point in the hot rolling process. The terminal computer sets the rolling conditions of the equipment at a later stage than the position of the device for detecting the entry of the rolling target material according to the previously-defined rolling conditions. After this step, the material to be calendered is sent to the aforementioned equipment for calendering. ----------—______ This paper size applies to China National Standard (CNS) A4 specification (210X297 mm)-504413 A7 B7 V. Description of the invention (2) In the purchase of the I The thin rods were joined. The joining technology is the same as in Japanese Patent Application Laid-Open No. 8-3000008 and the applicant of this case (please read the precautions on the back before filling this page) Japanese Patent Application Laid-Open No. 7-2 4 5 0 4 The disclosed technology: The device disclosed in Japanese Unexamined Patent Application Publication No. 8-3000008 is provided with adjustments to one or both of the holding device for a thin end rod and the holding device for a subsequent thin rod. Laser welding device for joint up and down position adjustment device. The device disclosed in Japanese Patent Application Laid-Open No. 7-2 4 5 0 4 opens the gap between the tail end of the heated front thin rod and the front end of the subsequent thin rod, and is held by the upper and lower arms respectively. A gripping device that moves the clamp arm to press the adjacent surfaces of the front end of the thin rod and the front end of the subsequent thin rod in a holding state to engage them. This holding device is provided with a horizontal locality holding device 'which has a pressure plate which can be held by one thin rod across the other thin rod. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, Japanese Patent Laid-Open No. 8-3 0 0 0 8 device must be either the front-end thin rod holding device or the subsequent thin-rod holding device. Or, on both sides, a mechanism for adjusting the position of the joint surface is provided, which results in an overly complicated structure. When the thickness of the subsequent material 12 is greater than the thickness of the front-end material 10, the material thickness at the joint portion 11 will form a step. This step is shown in Figure 1. When the final calender is used for the delay time, the forces from the upper and lower rollers 14 and 15 will act on the step of the material in the direction shown in the figure. As a result, there is a danger that the joint 11 between the front material and the subsequent material will break.

Description of the invention (3) As shown in Figure 2 . In Figure 2, when the holding parts are 18 and 19 when the material is thinner than that of the front end, the pressure plate is used to hold the materials: Middle '16, 17 are the upper and lower holding parts on the entrance side and the outlet side. The problem of bending the platen once it has passed through the subsequent material. In addition, the applicant in this case proposed a technique for setting consecutive rolling conditions in Japanese Unexamined Patent Publication No. 10-58 (Japanese Unexamined Patent Publication No. 06-92). The technology disclosed in the above-mentioned technology is a technology for making the final plate thickness generally determined by the continuous rolling material. No. 1 6 9 9 2 The rolling target cannot be rolled. Therefore, it is necessary to pre-plan the bonding sequence of a material such as a rolling sequence of a thin steel strip. The technical department disclosed by Japanese Patent Laid-Open, when the continuous drawing pressure delay is scheduled, it is immediately switched to first determine the rolling conditions for continuous rolling and punching pressure. However, the technique disclosed in Japanese Patent Application Laid-Open No. 010-58 30 0 KAI Hei 1 1-116 9 9 2 6 solves the problems of breakage risk and pressure plate bending problems caused by the aforementioned materials.

The paper size printed by the Bureau ’s Consumer Cooperative is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm). [Disclosure of the Invention] In order to solve the aforementioned traditional problems, the present invention is to prevent the damage of the pressure plate during joining and ensure continuous pressing delay. The problem is the joint strength and reduction of the burden on the rollers. The present invention solves the aforementioned problems in continuous rolling by rolling after uniformizing the thickness of the thin rods. When hot rolling, the host computer determines the rolling conditions in advance according to the type, size, size, product thickness, and product width of each rolled material. When the aforementioned rolling object is printed ~-504413 A7 B7 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. 5. Description of the invention (4) The material to be rolled is continuously rolled, and the terminal computer performs the calculation described later. The terminal computer system 'compares a plurality of continuously rolled front-end materials and subsequent materials' with a predetermined thin rod thickness and finds the smallest value 値. The above-mentioned problem is solved by uniformly rolling the thickness of the ytterbium rod to the minimum ytterbium. Traditionally, since the subsequent material is thicker than the front-end material, when the force from the final calender roll is applied to the thin rod joint, there is a problem that the joint is broken. In the present invention, since the plate thicknesses of a plurality of rolling target materials to be continuously rolled are unified, the above-mentioned problem does not occur. The effects of the present invention are shown in 3A and 3B. In Fig. 3A, the joint was successfully inserted into the final rolled rafters. The pressure plates 16 and 17 of the holding device in Fig. 3B did not bend. [Best Mode for Invention] Next, the embodiment of the present invention will be described in detail with reference to the drawings. ○ Figure 4 shows a main example of a hot rolling process for continuous rolling. A description will be given of a state in which continuous rolling is performed using this hot rolling process. The leading end 10 e of the front end material 10 e and subsequent materials; the leading end 1 2 t of [2 is joined by a joining device 30 located in the middle of the three-stage rough calender 20 and the seven-stage final calender 40. The front material 10 and the subsequent material 12 are continuously and finally rolled in a connected state. In the subsequent process of the final calender 40, a cutting machine 50 for the target material to be calendered is installed, and two coilers 60 are installed behind the cutting machine 50. The paper size of the front-end material 1 〇 and subsequent materials applies the Chinese National Standard (CNS) A4 specification (210X297 mm) (Please read the precautions on the back before filling in this page) Binding and binding • j__ 504413 A7 ___B7 5. Description of the invention (5) (Please read the precautions on the back before filling in this page) Material 1 2 In the connected state, the target material for the final calendering is cut by the aforementioned cutting machine 50 into a winder 6 0 . The rolling of the rolling target material at the front end more than the cutting point and the rolling target material at the rear end of the cutting point are performed by two coilers. In the continuous final rolling system, the front material 10 and the subsequent material 12 are continuously rolled without interruption. It is possible to perform stable rolling throughout, and it is especially suitable for the rolling of thin rolling target materials with irregular front ends. Fig. 5 is a block diagram example showing a control device for implementing the present invention. As shown in Figure 5, the operating conditions of each equipment in the hot rolling process are set by a computer. The information such as the steel type, specification, and rolling size of each rolled plate as the rolling target material is input from the command input device 80. For example, the information of each of the aforementioned rolling plates is transmitted to the host computer 70 via the company's intranet 8 2. The host computer 70 determines the rolling conditions such as the rolling temperature, the rolling progress, the rolling speed, the tension between the stations, and the cooling conditions of the rolling target materials based on the information of the aforementioned rolling plates. The host computer 70 instructs the terminal computer 72 to issue the aforementioned rolling conditions. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs When the rolling board is put into the rolling process, the terminal computer 7 2 reads the detection 値 measured by the detectors arranged in the rolling process. Detectors refer to the detector 2 4 on the exit side of the coarse calender, the detector 3 2 on the exit side of the bonding device, and the detector 4 4 on the exit side of the final calender in the fifth figure. The so-called detection line refers to information such as temperature, board thickness, and board width. At the same time, the terminal computer 72 also reads the actual operation data of the equipment / equipment. The equipment is the rough calender 20, the bonding device 30, the final calender 40, the cutting machine 50, and the coiler 60 in the fifth figure. The actual operating data is based on the China National Standard (CNS) A4 specification (21〇 > < 297 mm) for the rough calendered paper size. &Quot; " " 504413 A7 ______B7_ V. Description of the Invention (6) Machine 2 0 The rolling load at the pressing device 22 and the final rolling machine 40 at the pressing device 42. The detection card obtained by the detector and the actual operation data are collectively referred to as rolling target material information. Based on the material information of the rolling target, the terminal computer 72 series performs rolling according to the rolling conditions issued by the host computer 70, and calculates the operating conditions of subsequent stations at the current location where the rolling target material is located. The terminal computers 72 and 2 send the operating conditions to each device based on the results of the calculations described above, and operate each device. An example is given below for further detailed description. For example, in the press rolling operation, the terminal computer 72 series, based on the material information of the rolling target in the rough rolling state, cooperates with the final rolling conditions issued by the host computer 70 to perform the final rolling, and estimates the operation of the final rolling machine 40. The condition is the depression position of each station and the number of roller revolutions. The material information of the rolling target in the rough rolling state refers to information such as the size and temperature of the thin rod after the rough rolling step is completed. This information can be obtained from the detector 24 on the exit side of the rough calender, or it can be obtained by calculating the actual operation data of the rough calender 20. In addition, for example, in a continuous calendering operation, after the joining of the front-end material 10 and the subsequent material 12 is completed by the joining device 30, the terminal computer 72 calculates the operating conditions of the final calender 40 for the subsequent material 12. The next steps are the same as the aforementioned press-pressing delay, and the final calendering is performed in accordance with the final calendering conditions issued by the main computer 70, and the operating conditions of the final calender 40 are estimated. The above processes are all shown in Figure 6. In the present invention, each calendered image-sealing material is compared with a predetermined thin rod thickness, and its paper size is further adapted to the ^^^ standard (CNS) A4 specification (2ιχχ297 common product ------ --- Install— (Please read the notes on the back before filling out this page) Order printed by the Intellectual Property Bureau employee consumer cooperative of the Ministry of Economic Affairs 504413 A7 B7 Printed by the employee property cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 5. Description of the invention (7) Thin The thickness of the rod is uniformly the smallest of them. The method of determination is as shown in Figure 7. The basic information is the type of steel, specifications, rolled size, specified thickness after hot rolling, and specified width after hot rolling. The thickness of the thin rod is retrieved from the setting list recorded in the host computer 70 in advance. As shown in FIG. 7, it is preferable to register the thickness of the thin rod for both continuous rolling and punching. The setting of the thin rod thickness 値It is entered in the list in advance. In order to ensure that the rolled product becomes a processed material with good strength and ductility, it is necessary to (1) reduce the energy loss by heat dissipation, and (2) maintain a high final rolling temperature. For this reason, the thickness of the thin rod is preferably thicker. However, when the thickness of the final rolled sheet is thinner, in order to reduce the load on the final calender, the thickness of the thin rod is preferably thinner. On the contrary, when considering different When the thickness of the thin rod is determined under the conditions of the foregoing state, the thickness of the thin rod can also be determined only by the punch rolling, or both by the punch rolling and continuous rolling. Now, let η be the number of materials for continuous rolling. According to the above logic, t 1, t 2, ... t η are taken as the thickness of each sheet of material. A combination of plural continuous rolling target materials is called a continuous rolling unit. The present invention relates to t 1 in the continuous rolling unit. , T 2, ... t η are compared, and for all rolling objects in the continuous rolling unit, the setting 値 of the thickness of the thin rod is set to M in (t 1, t 2, ... t η), and M i η ( ) Is a function of the minimum value of several variables in parentheses. When the thickness of the thin rod is determined by the pressing of the punch alone, according to the foregoing description, the minimum plate thickness can be determined by M in (t 1, t 2, ... t η). If according to the press and continuous rolling For the minimum board thickness for continuous calendering, please also (please read the precautions on the back before filling out this page) 0, binding and binding This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) ) 504413 A7 B7___ V. Description of the invention (8) can be determined by Min (tl, t2, ... tn). As described above, the material to be rolled is compared with a predetermined thickness of the thin rod, and the thickness of the thin rod is unified. (Example) When the thickness of the thin rod is determined only by the punching of the press, 'the actual specific thickness of the thin rod for continuous rolling is shown in Table 1. Table 1 shows' No. N 〇' _ Examples of 6 sheets of rolling materials of the same type (low carbon steel) No. 1 to 6 which are joined at the entrance side of the final calender and are subjected to continuous final calendering. In the conventional punching and calendering, the thickness of a thin rod for each material to be rolled is set. When the continuous compression delay is performed, it is unified to a minimum thickness (No. 4 in the table) of 30 legs. —------- 装 — {Please read the notes on the back before filling out this page) Order printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs.

Description of the invention (9) According to the present invention, it is possible to unify the continuous calendering unit in the continuous calendering unit. Thin rod thickness of the material to be rolled. Traditionally, since the subsequent material is thicker than the front-end material, when the force from the final calender roll is applied to the thin rod joint, the problem of joint breakage occurs. However, when the subsequent material is thinner than the front-end material, a problem arises in that when the material is held by a platen that spans the front-end material from the subsequent material, the platen is bent. However, according to the present invention, as shown in Fig. 3, a smooth joint can be formed to perform the final rolling.
