Abstract

The invention discloses a zinc pot roller simulation device and a zinc pot roller measuring and adjusting method, which are used for solving the technical problem of low position precision of a hot galvanizing zinc pot roller caused by difficulty in measuring the position of a sink roller body due to the fact that the sink roller body is positioned in zinc liquid after being mounted in the prior art. After being calibrated, the sink roll simulation assembly and the stabilizing roll simulation assembly in the zinc pot roll simulation device can replace a zinc pot sink roll and a zinc pot stabilizing roll to be installed on a sink roll installation seat and a stabilizing roll installation seat at the online position of a galvanizing unit respectively. The sink roll simulation roll and the first stabilizing roll simulation roll are both located on the liquid level of zinc liquid in a hot galvanizing pot, and a worker can determine the actual positions of a zinc pot sink roll and a zinc pot stabilizing roll which are installed on the sink roll installation base and the stabilizing roll installation base respectively by means of the sink roll simulation roll and the first stabilizing roll simulation roll. Therefore, the positions of the zinc pot sinking roller and the zinc pot stabilizing roller can be measured and adjusted more conveniently, and the position precision of the hot galvanizing zinc pot roller can be ensured.

Description

Technical Field

[0001] The present application belongs to the technical field of auxiliary devices for metallurgical galvanizing production lines, and specifically relates to a zinc pot roller simulation device and a method for measuring and adjusting the zinc pot roller. Background Art

[0002] The zinc pot roller equipment is one of the core equipment of the hot-dip galvanizing unit. The zinc pot roller equipment includes the zinc pot sinking roller, the zinc pot stabilizing roller and the zinc pot correcting roller. When producing hot-dip galvanized products, the sinking roller body in the zinc pot sinking roller, the stabilizing roller body in the zinc pot stabilizing roller and the correcting roller body in the zinc pot correcting roller are all immersed in the molten zinc liquid and rotate at high speed following the running strip steel.

[0003] During the production process, the position accuracy of the zinc pot roller is very important, especially the relative position relationship between the sinking roller and the stabilizing roller, and the position relationship between the sinking roller and the correcting roller, which will directly affect the surface quality of the galvanized product.

[0004] The zinc pot sinking roller specifically includes parts such as a sinking roller beam, a roller arm and a sinking roller body. In the prior art, before installing the zinc pot sinking roller, the zinc pot sinking roller must be installed on an offline calibration frame to calibrate the position of the sinking roller body, and then the calibrated zinc pot sinking roller must be hoisted onto the sinking roller mounting seat at the online position of the galvanizing unit for installation and fixation.

[0005] The installation method of the zinc pot stabilizing roller is the same as the installation method of the zinc pot sinking roller mentioned above. After the calibration is completed on the corresponding calibration frame, it is installed on the stabilizing roller mounting seat and fixed;

[0006] During the installation and fixing process, the positional relationship between the zinc pot sinking roller and the sinking roller mounting seat, as well as the zinc pot stabilizing roller and the stabilizing roller mounting seat, will change due to the matching relationship or the wear of the pin shaft. At this time, the sinking roller body and the stabilizing roller body are both immersed in the zinc liquid above 400 degrees, and the actual positions of the sinking roller body and the stabilizing roller body cannot be determined, and thus the positional relationship between the sinking roller body and the stabilizing roller body cannot be measured. The position data of the sinking roller body and the stabilizing roller body can only be calculated by indirectly measuring the sinking roller mounting seat and the column pins on the stabilizing roller mounting seat with the aid of instruments such as laser trackers, and then the sinking roller mounting seat and the stabilizing roller mounting seat are moved according to the measured position data to adjust the positional relationship between the zinc pot sinking roller and the zinc pot stabilizing roller.

[0007] However, the accuracy of this measurement method is low, and the temperature of the molten zinc in the zinc pot is as high as 400 degrees or more, and the ambient temperature around the zinc pot is also relatively high, which has a great impact on the measurement accuracy of laser instruments, making it extremely difficult to adjust the position of the sinking roller and the stabilizing roller, which in turn increases the difficulty of maintaining the zinc pot roller equipment. Therefore, inventing a device and method that can assist in the installation and positioning of the zinc pot roller equipment is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention

DETAILED DESCRIPTION

[0044] In order to enable technicians in the technical field to which the present application belongs to understand the present application more clearly, the technical solution of the present application is described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0045] In the embodiments of the present application, Figures 1 to 8 As shown, the zinc pot roller simulation device includes a sinking roller simulation component 1 and a stabilizing roller simulation component 2; wherein,

[0046] The sinking roller simulation assembly 1 comprises a sinking roller simulation bracket 11 and a sinking roller simulation roller 12. The sinking roller simulation roller 12 is mounted on the mounting end of the sinking roller simulation bracket 11. The distance between the axis of the sinking roller simulation roller 12 and the liquid surface in the hot-dip galvanizing pot is greater than or equal to 200 mm.

[0047] The stabilizing roller simulation assembly 2 includes a stabilizing roller simulation bracket 21 and a first stabilizing roller simulation roller 22. The first stabilizing roller simulation roller 22 is mounted on the mounting end of the stabilizing roller simulation bracket 21. The axis of the first stabilizing roller simulation roller 22 is in the same horizontal plane as the axis of the sinking roller simulation roller 12.

[0048] Before adjusting the positions of the sinking roller mounting seat and the stabilizing roller mounting seat, the sinking roller simulation component 1 and the stabilizing roller simulation component 2 may be installed on an offline calibration frame for calibration;

[0049] During the calibration process, the axis of the sinking roller simulation roller 12 is parallel to the horizontal plane, and the side of the sinking roller simulation roller 12 away from the sinking roller simulation bracket 11 is tangent to the galvanizing line rolling line. At the same time, the axis of the first stabilizing roller simulation roller 22 is parallel to the horizontal plane, and the axis of the first stabilizing roller simulation roller 22 is parallel to the galvanizing line rolling line. Figure 1 ;

[0050] After the calibration is completed, the side of the sinking roller simulation roller 12 on the calibration frame away from the sinking roller simulation bracket 11 is located in the same vertical plane as the working side of the sinking roller body in the zinc pot sinking roller (the side where the sinking roller body is in contact with the galvanizing line rolling line), that is, the position of the working side of the sinking roller body can be determined by the side of the sinking roller simulation roller 12 away from the sinking roller simulation bracket 11; the side of the first stabilizing roller simulation roller 22 away from the stabilizing roller simulation bracket 21 is located in the same vertical plane as the working side of the stabilizing roller body in the zinc pot stabilizing roller (the side where the stabilizing roller body is in contact with the galvanizing line rolling line), that is, the position of the working side of the stabilizing roller body can be determined by the side of the first stabilizing roller simulation roller 22 away from the stabilizing roller simulation bracket 21;

[0051] After the calibration is completed, the sinking roller simulation component 1 and the stabilizing roller simulation component 2 are respectively installed on the sinking roller mounting seat and the stabilizing roller mounting seat on the line position of the galvanizing line. At this time, the sinking roller simulation roller 12 and the first stabilizing roller simulation roller 22 are both located above the zinc liquid. The staff can obtain the actual position of the working side of the zinc pot sinking roller and the working side of the zinc pot stabilizing roller through the sinking roller simulation roller 12 and the first stabilizing roller simulation roller 22;

[0052] If the actual positions of the working side of the zinc pot sinking roller and the working side of the zinc pot stabilizing roller do not meet the requirements, that is, the actual positions of the zinc pot sinking roller and the zinc pot stabilizing roller deviate from the standard positions of the zinc pot sinking roller and the zinc pot stabilizing roller, the staff can adjust the actual positions of the sinking roller simulation roller 12 and the first stabilizing roller simulation roller 22 by adjusting the sinking roller mounting seat and the stabilizing roller mounting seat, so that the positions of the side of the sinking roller simulation roller 12 away from the sinking roller simulation bracket 11 and the side of the first stabilizing roller simulation roller 22 away from the stabilizing roller simulation bracket 21 meet the requirements;

[0053] Then the sinking roller simulation roller 12 and the first stabilizing roller simulation roller 22 on the sinking roller mounting seat and the stabilizing roller mounting seat can be removed, and the calibrated zinc pot sinking roller and the zinc pot stabilizing roller can be installed on the sinking roller mounting seat and the stabilizing roller mounting seat respectively to complete the position adjustment of the zinc pot sinking roller and the zinc pot stabilizing roller, and the adjustment process can be carried out using measuring tools such as feeler gauges and gauge blocks to make the adjustment of the position of the hot-dip galvanizing zinc pot roller more convenient and to ensure the position accuracy of the hot-dip galvanizing zinc pot roller.

[0054] The axis of the sinking roller simulation roller 12 is set at a position more than 200 mm above the liquid level in the hot-dip galvanizing pot to facilitate the staff to carry out measurement work, so as to make the measurement of the zinc pot roller simulation device more convenient.

[0055] In some embodiments, the above-mentioned sinking roller simulation support 11 includes a sinking roller simulation beam 111 and a sinking roller simulation support arm 112, see Figures 3 to 5 ;in,

[0056] The structure of the sinking roller simulation beam 111 is exactly the same as the structure of the beam used to support the sinking roller body in the zinc pot sinking roller. There are two sinking roller simulation arms 112. The fixed ends of the two sinking roller simulation arms 112 are connected to the sinking roller simulation beam 111, and the two sinking roller simulation arms 112 are respectively arranged near the two ends of the stabilizing roller simulation beam 211.

[0057] In this embodiment, the diameter of the sinking roller simulation roller 12 is 40 mm and the length is 1800 mm, which is smaller than the sinking roller body. The installation position of the fixed end of the sinking roller simulation support arm 112 is the same as the installation position of the support arm in the sinking roller body. Therefore, the sinking roller simulation support arm 112 is set to be "L" shaped, and the movable end of the sinking roller simulation support arm 112 extends toward the center direction of the sinking roller simulation cross beam 111, shortening the distance between the movable ends of the two sinking roller simulation support arms 122, so that the sinking roller simulation The distance between the two movable ends of the support arm 112 matches the length of the sinking roller simulation roller 12, so that the two ends of the sinking roller simulation roller 12 can be respectively installed on the movable ends of the two sinking roller simulation support arms 112, and the plane where the sinking roller simulation support arms 112 are located is parallel to the horizontal plane, ensuring the parallelism of the sinking roller simulation roller 12 after installation. When adjusting the sinking roller simulation roller 12, only fine-tuning is required to make the axis of the sinking roller simulation roller 12 parallel to the horizontal plane, thereby reducing the calibration difficulty of the sinking roller simulation assembly 1.

[0058] In some embodiments, a sinking roller simulation fixing seat 113 is provided on the above-mentioned sinking roller simulation support arm 112, and the end of the sinking roller simulation roller 12 is provided on the sinking roller simulation fixing seat 113;

[0059] During the calibration process, the position of the axis of the sinking roller simulation roller 12 can be adjusted by adjusting the positions of the two sinking roller simulation fixing seats 113, such as adjusting the horizontality of the axis of the sinking roller simulation roller 12 by padding (laying washers, etc.), and adjusting the positional relationship between the axis of the sinking roller simulation roller 12 and the galvanizing line rolling line by moving forward and backward (close to or away from the sinking roller simulation crossbeam 111);

[0060] By the above method, the axis of the sinking roller simulation roller 12 can be easily adjusted to be parallel to the horizontal plane, and the side of the sinking roller simulation roller 12 away from the sinking roller simulation beam 111 is tangent to the galvanizing line rolling line.

[0061] In some embodiments, the above-mentioned stabilizing roller simulation support 21 includes a stabilizing roller simulation crossbeam 211 and a stabilizing roller simulation support arm 212, see Figures 6 to 8 ;in,

[0062] The structure of the simulated cross beam 211 of the stabilizing roller is exactly the same as the structure of the cross beam used to support the stabilizing roller body in the zinc pot stabilizing roller. There are two simulated arms 212 of the stabilizing roller. The fixed ends of the two simulated arms 212 of the stabilizing roller are connected to the simulated cross beam 211 of the stabilizing roller, and the two simulated arms 212 of the stabilizing roller are respectively arranged near the two ends of the simulated cross beam 211 of the stabilizing roller.

[0063] In this embodiment, the diameter of the first stabilizing roller simulation roller is 40 mm and the length is 1800 mm, which is smaller than the stabilizing roller body, and the installation position of the fixed end of the stabilizing roller simulation arm 212 is the same as the installation position of the arm of the stabilizing roller body. Therefore, the stabilizing roller simulation arm 212 is set to be "L"-shaped, and the movable end of the stabilizing roller simulation arm 212 extends toward the center direction of the stabilizing roller simulation beam 211, shortening the spacing between the movable ends of the two stabilizing roller simulation arms 212, so that the distance between the two movable ends of the stabilizing roller simulation arm 212 matches the length of the first stabilizing roller simulation roller 22, so that the two ends of the first stabilizing roller simulation roller 22 can be respectively installed on the movable ends of the two stabilizing roller simulation arms 212, and the plane where the stabilizing roller simulation arm 212 is located is parallel to the horizontal plane, ensuring the parallelism of the simulation roller B22 after installation. During adjustment, only fine-tuning is required to make the axis of the simulation roller B22 parallel to the horizontal plane, so as to reduce the calibration difficulty of the stabilizing roller simulation component 2.

[0064] Since the height of the stabilizing roller mounting seat on the galvanizing line is lower than that of the sinking roller mounting seat, in order to ensure that the first stabilizing roller simulation roller 22 is located above the zinc liquid and the axis of the first stabilizing roller simulation roller 22 is in the same horizontal plane as the axis of the sinking roller simulation roller 12, a column 214 is provided at the movable end of the stabilizing roller simulation arm 212, and the length direction of the column 214 is perpendicular to the plane where the stabilizing roller simulation arm 212 is located. The end of the first stabilizing roller simulation roller 22 is rotatably set on the column 214 to increase the height of the first stabilizing roller simulation roller 22, thereby ensuring that the position of the first stabilizing roller simulation roller 22 can extend above the liquid surface of the zinc liquid, and the axis of the first stabilizing roller simulation roller 22 is in the same horizontal plane as the axis of the sinking roller simulation roller 12, so as to facilitate the measurement and adjustment of the spacing between the first stabilizing roller simulation roller 22 and the sinking roller simulation roller 12.

[0065] In some embodiments, the movable end of the above-mentioned column 214 is provided with a stabilizing roller simulation fixing seat 213, and the end of the first stabilizing roller simulation roller 22 is provided on the stabilizing roller simulation fixing seat 213;

[0066] During the calibration process, the position of the axis of the first stabilizing roller simulation roller 22 can be adjusted by adjusting the positions of the two stabilizing roller simulation fixing seats 213, such as adjusting the horizontality of the axis of the first stabilizing roller simulation roller 22 by raising it (laying washers, etc.), and adjusting the positional relationship between the axis of the first stabilizing roller simulation roller 22 and the galvanizing line rolling line by moving it forward and backward (close to or away from the stabilizing roller simulation crossbeam 211);

[0067] By the above method, the axis of the first stabilizing roller simulation roller 22 can be easily adjusted to be parallel to the horizontal plane, and the side of the first stabilizing roller simulation roller 22 away from the stabilizing roller simulation beam 211 is parallel to the galvanizing line rolling line.

[0068] In order to better adjust and confirm the position of the second stabilizing roller simulation roller 23, the above-mentioned stabilizing roller simulation assembly 2 also includes a second stabilizing roller simulation roller 23, see Figure 7 ;in,

[0069] The first stabilizing roller simulation roller 22 and the second stabilizing roller simulation roller 23 are both mounted on the mounting end of the stabilizing roller simulation bracket 21, that is, on the above-mentioned stabilizing roller simulation fixing seat 213, and the second stabilizing roller simulation roller 23 is located on the side of the first stabilizing roller simulation roller 22 away from the stabilizing roller simulation crossbeam 211;

[0070] During the calibration process, the position of the second stabilizing roller simulation roller 23 can be adjusted so that the side away from the first stabilizing roller simulation roller 22 is tangent to the galvanizing line rolling line, and then the distance between the first stabilizing roller simulation roller 22 and the second stabilizing roller simulation roller 23 is adjusted to ensure that the side of the first stabilizing roller simulation roller 22 away from the stabilizing roller simulation beam 211 is parallel to the galvanizing line rolling line.

[0071] At the same time, when the axis of the first stabilizing roller simulation roller 22 and the axis of the sinking roller simulation roller 12 are in the same horizontal plane, the second stabilizing roller simulation roller 23 and the sinking roller simulation roller 12 have the characteristic of coinciding the axis;

[0072] In order to avoid the interference between the second stabilizing roller simulation roller 23 and the sinking roller simulation roller 12 when the sinking roller simulation component 1 and the stabilizing roller simulation component 2 are installed on the sinking roller mounting seat and the stabilizing roller mounting seat, after completing the calibration of the stabilizing roller simulation component 2, the second stabilizing roller simulation roller 22 in the stabilizing roller simulation component 2 can be removed, and then the sinking roller simulation component 1 and the stabilizing roller simulation component 2 can be installed on the sinking roller mounting seat and the stabilizing roller mounting seat respectively, and the distance between the sinking roller simulation roller 12 and the first stabilizing roller simulation roller 22 is adjusted to ensure that the axis of the sinking roller simulation roller 12 is parallel to the axis of the first stabilizing roller simulation roller 22, and the distance between the working side of the zinc pot sinking roller and the working side of the zinc pot stabilizing roller is determined.

[0073] It should be noted that the distance between the working side of the zinc pot sinking roller and the working side of the zinc pot stabilizing roller is equal to the distance between the sinking roller simulation roller 12 and the first stabilizing roller simulation roller 22 plus the diameter of the sinking roller simulation roller 12; the distance between the sinking roller simulation roller 12 and the first stabilizing roller simulation roller 22 refers to the distance between the side of the sinking roller simulation roller 12 facing the first stabilizing roller simulation roller 22 and the side of the first stabilizing roller simulation roller 22 facing the sinking roller simulation roller 12.

[0074] In some embodiments, the horizontality of the axis of the above-mentioned sinking roller simulation roller 12 is controlled within a precision range of 0.02 mm / m; the horizontality of the axis of the first stabilizing roller simulation roller 22 is controlled within a precision range of 0.02 mm / m.

[0075] Based on the above method, the positional relationship between the correction roller body and the sinking roller body can also be determined. Based on the above idea, a correction roller simulation component for replacing the zinc pot correction roller is set, and the position of the correction roller simulation roller in the correction roller simulation component and the positional relationship between the correction roller simulation roller and the first stabilizing roller simulation roller 22 are calibrated;

[0076] Then install the calibrated correction roller simulation assembly on the correction roller mounting seat on the galvanizing line, and adjust the position relationship between the correction roller simulation roller and the first stabilizing roller simulation roller 22 and the position relationship between the correction roller simulation roller and the galvanizing line rolling line by moving the correction roller mounting seat;

[0077] After the position of the correction roller simulation roller is determined, the correction roller simulation assembly is removed from the correction roller mounting seat, and the zinc pot correction roller is mounted on the correction roller mounting seat to complete the adjustment of the position of the correction roller mounting seat.

[0078] Through the above embodiments, the present application has the following beneficial effects or advantages:

[0079] The sinking roller simulation component 1 and the stabilizing roller simulation component 2 in the zinc pot roller simulation device can replace the zinc pot sinking roller and the zinc pot stabilizing roller and be installed on the sinking roller mounting seat and the stabilizing roller mounting seat of the galvanizing unit online position respectively after calibration. The sinking roller simulation roller 12 and the first stabilizing roller simulation roller 22 are both located on the liquid surface of the zinc liquid in the hot-dip galvanizing pot. The staff can use the sinking roller simulation roller 12 and the first stabilizing roller simulation roller 22 to determine the actual positions of the zinc pot sinking roller and the zinc pot stabilizing roller respectively installed on the sinking roller mounting seat and the stabilizing roller mounting seat, making it more convenient to measure and adjust the positions of the zinc pot sinking roller and the zinc pot stabilizing roller. After the position adjustment is completed, the sinking roller simulation roller 12 and the first stabilizing roller simulation roller 22 are removed and the calibrated zinc pot sinking roller and zinc pot stabilizing roller are respectively installed on the sinking roller mounting seat and the stabilizing roller mounting seat, so as to easily and quickly complete the position adjustment of the hot-dip galvanizing zinc pot roller and ensure the position accuracy of the hot-dip galvanizing zinc pot roller.
