Description
Technical Field
[0001] This utility model relates to the field of electroslag furnace technology, specifically to an electroslag furnace with a weighing mechanism. Background Technology
[0002] In the field of electroslag remelting furnace technology, the electrode is a core component, and its position adjustment accuracy, clamping stability, and weight monitoring are crucial to smelting quality and efficiency. Traditional electroslag remelting furnaces have many limitations in electrode operation:
[0003] During the smelting and weighing process, the electrodes need to be fixed and moved and rotated. The existing multi-angle rotation and height adjustment of the electrodes mostly rely on manual handling or simple mechanical structures, which is not only difficult to operate and time-consuming, but also difficult to meet the precise requirements of electrode position in different smelting scenarios, and the smelting effect is easily affected by position deviation.
[0004] Existing electrode fixing mechanisms are usually only compatible with electrodes of a specific diameter. They lack universal clamping capability for electrodes of different specifications and have insufficient clamping stability. Electrodes are prone to displacement or shaking during operation, resulting in unstable electric arcs, which affects the formation of the molten metal pool and the quality of ingot casting.
[0005] Electrodes are continuously consumed during the smelting process. Traditional electroslag furnaces lack a weighing mechanism, making it difficult for operators to accurately grasp the remaining amount of electrodes and to precisely calculate electrode loss in order to optimize smelting parameters. Therefore, it is necessary to design an electroslag furnace with a weighing mechanism to solve the above problems. Utility Model Content

A clamping plate is fixedly connected to the right side of the connecting arm, and an electrode body is disposed inside the clamping plate. The electrode body is disposed on the top of the weighing mechanism.
[0009] Preferably, the rotating rod is rotatably connected to the inside of the base, and the fixing frame is fixedly connected to the top of the base, so as to ensure the stability of the fixing platform through the fixing frame.
[0010] Preferably, the movable seat is slidably connected to the inside and outside of the support frame, and the bidirectional threaded rod is rotatably connected to the inside of the rectangular frame, so as to facilitate the movement of the connecting arm by driving the bidirectional threaded rod.
[0011] Preferably, the connecting arm is slidably connected inside the rectangular frame, and the electrode body is slidably connected inside the crystallizer, so that the clamping plate can be moved by the connecting arm.
[0012] Preferably, the inner side of the clamp is in contact with the outer periphery of the electrode body, which facilitates fixing the electrode body through the clamp.
[0013] Preferably, the connecting arm and clamp are provided in two sets, symmetrically distributed on the left and right sides of the periphery of the bidirectional threaded rod, and both sets of clamps are V-shaped, so that electrode bodies of different sizes can be fixed by providing two sets.
[0014] Preferably, the weighing mechanism includes a weighing platform, which is fixedly connected to the top left side of the base. A weight sensor is fixedly connected to the top of the weighing platform. A movable frame is fixedly connected to the rear side of the weighing platform. A connecting column is slidably connected inside the movable frame. The connecting column is slidably connected to the inside of the weighing platform. A fixed shaft is threaded inside the connecting column. A limit frame is fixedly connected to the top of the front surface of the connecting column. The limit frame is located around the electrode body.
[0015] Preferably, the top of the weighing platform and the top of the weight sensor are in contact with the bottom of the electrode body, the inner side of the limiting frame is in contact with the outer side of the electrode body, and the limiting frame is V-shaped, so that the electrode body can be fixed by the limiting frame when the electrode body is on the top of the weighing platform.
[0016] Preferably, the weighing platform and the moving frame are respectively provided with moving slots, and the two moving slots correspond to each other. The connecting column is slidably connected in the moving slot, and the fixed shaft passes through the moving frame, so as to ensure the stability of the moving column through the fixed shaft.
[0017] Preferably, the movable frame, fixed shaft, connecting column and limiting frame are provided in two sets and are symmetrically distributed on the front and rear sides of the weighing platform. The weight sensor is electrically connected to the display screen to facilitate weighing of the electrode body through the weight sensor.
[0018] Compared with the prior art, this utility model provides an electroslag furnace with a weighing mechanism, which has the following beneficial effects:
[0019] 1. This electroslag furnace with a weighing mechanism, through a fixed mechanism, uses a first servo motor to drive the rotating rod and fixed platform to rotate. Combined with the limiting effect of the fixed frame, it can easily achieve multi-angle adjustment of the electrode body, meeting the diverse needs of the electroslag furnace for electrode position in different working scenarios. No manual handling or adjustment is required, significantly reducing operational difficulty. The first hydraulic cylinder drives the moving seat to move up and down, precisely controlling the lifting and lowering of the electrode body to ensure the electrode accurately enters the appropriate depth within the crystallizer, improving operational accuracy. Meanwhile, the second servo motor within the rectangular frame drives the bidirectional threaded rod to rotate, causing the two sets of connecting arms to move the V-shaped clamps synchronously closer or further away, securely clamping electrode bodies of different diameters. This effectively prevents electrode displacement or shaking during operation, ensuring the smooth progress of the electroslag smelting process. Simultaneously, during use, it can rotate the electrode body, moving it to the top of the weighing platform for weighing.
[0020] 2. In this electroslag furnace with a weighing mechanism, when the weight of the electrode body needs to be weighed during the operation of the electroslag furnace, the electrode body is moved to the middle position of the top of the weighing platform under the action of the fixing mechanism. The weight sensor on the top of the weighing platform can accurately monitor the weight of the electrode body and, through electrical connection with the display screen, present the weight data intuitively to the operator. This allows the operator to keep track of the electrode consumption at any time, facilitate timely electrode replacement, and avoid affecting the smelting process due to insufficient electrodes. Two sets of symmetrically distributed moving frames, fixed shafts, connecting columns, and limiting frames can adjust the position of the limiting frames by sliding the connecting columns in the moving groove, and then be fixed by the fixed shaft. The V-shaped limiting frames contact the outer periphery of the electrode body, which not only provides auxiliary fixing for the electrode but also does not affect the normal weighing of the weight sensor.

[0032] This utility model provides the following technical solution:
[0033] Example 1
[0034] Please see Figure 1-7 This utility model provides a technical solution: an electroslag furnace with a weighing mechanism, including a base 1, a crystallizer 2 fixedly connected to the front top of the base 1, a fixing mechanism 4 set on the top of the base 1, a display screen 3 fixedly connected to the right top of the base 1, and a weighing mechanism 5 set on the left top of the base 1.

A rotating rod 45 is fixedly connected to the top of the first servo motor 41. A fixed platform 42 is fixedly connected to the top of the rotating rod 45. A fixed frame 44 is rotatably connected to the periphery of the fixed platform 42. A support frame 43 is fixedly connected to the top of the fixed platform 42. A first hydraulic cylinder 46 is fixedly connected to the top of the support frame 43. A movable seat 47 is fixedly connected to the bottom of the first hydraulic cylinder 46. A rectangular frame 48 is fixedly connected to the front of the movable seat 47. A second servo motor 492 is fixedly connected to the left side of the rectangular frame 48. A bidirectional threaded rod 49 is fixedly connected to the right side of the second servo motor 492. A connecting arm 493 is threadedly connected to the periphery of the bidirectional threaded rod 49. A clamping plate 494 is fixedly connected to the right side of the connecting arm 493.

[0036] The rotating rod 45 is rotatably connected to the inside of the base 1, and the fixed frame 44 is fixedly connected to the top of the base 1, so as to ensure the stability of the fixed platform 42 through the fixed frame 44.
[0037] The movable seat 47 is slidably connected to the inside and outside of the support frame 43, and the bidirectional threaded rod 49 is rotatably connected to the inside of the rectangular frame 48, so that the connecting arm 493 can be moved by the bidirectional threaded rod 49.
[0038] The connecting arm 493 is slidably connected inside the rectangular frame 48, and the electrode body 491 is slidably connected inside the crystallizer 2, so that the clamping plate 494 can be moved by the connecting arm 493.
[0039] The inner side of the clamp 494 is in contact with the outer side of the electrode body 491, which facilitates the fixing of the electrode body 491 through the clamp 494.
[0040] Two sets of connecting arms 493 and clamping plates 494 are provided and symmetrically distributed on the left and right sides of the periphery of the bidirectional threaded rod 49. Both sets of clamping plates 494 are V-shaped, which makes it easy to fix electrode bodies 491 of different sizes by setting two sets.
[0041] Example 2
[0042] Please see Figure 1-7 Furthermore, based on Embodiment 1, the weighing mechanism 5 further includes a weighing platform 51, which is fixedly connected to the top left side of the base 1. A weight sensor 52 is fixedly connected to the top of the weighing platform 51. A movable frame 53 is fixedly connected to the rear side of the weighing platform 51. A connecting column 55 is slidably connected inside the movable frame 53. The connecting column 55 is slidably connected inside the weighing platform 51. A fixed shaft 54 is threaded inside the connecting column 55. A limit frame 56 is fixedly connected to the top of the front surface of the connecting column 55. The limit frame 56 is located around the electrode body 491.
[0043] The top of the weighing platform 51 and the top of the weight sensor 52 are in contact with the bottom of the electrode body 491. The inner side of the limiting frame 56 is in contact with the outer side of the electrode body 491, and the limiting frame 56 is V-shaped, so that when the electrode body 491 is on the top of the weighing platform 51, the limiting frame 56 can fix the electrode body 491.
[0044] The weighing platform 51 and the moving frame 53 are respectively provided with moving slots, and the two moving slots correspond to each other. The connecting column 55 is slidably connected in the moving slot, and the fixed shaft 54 passes through the moving frame 53, so as to ensure the stability of the moving column through the fixed shaft 54.
[0045] Two sets of movable frame 53, fixed shaft 54, connecting column 55 and limiting frame 56 are provided and symmetrically distributed on the front and rear sides of weighing platform 51. Weight sensor 52 is electrically connected to display screen 3 to facilitate weighing of electrode body 491 through weight sensor 52.
[0046] In actual operation, when this device is used, when the electroslag furnace is in use, firstly select the appropriate slag material according to the smelting requirements, and dry it in advance to remove moisture. Put the slag material into the crystallizer 2, and apply a release agent to the inner wall of the crystallizer 2 to facilitate ingot demolding. At the same time, place an arc-initiating agent at the bottom of the crystallizer 2. Place the electrode body 491 on the top right side of the base 1. Drive the moving seat 47 and the rectangular frame 48 to move through the first hydraulic cylinder 46, and drive the rotating rod 45 and the fixed platform 42 to rotate through the first servo motor 41, which can drive the support frame 43 to rotate, so that the two sets of clamping plates 494 are on the periphery of the electrode body 491. Further, under the action of the first hydraulic cylinder 46, adjust the height of the two sets of clamping plates 494 to make them in a suitable position on the periphery of the electrode body 491. After the adjustment is completed, drive the bidirectional threaded rod 49, which is threadedly connected to the connecting arm 493 and the clamping plate 494, to move through the second servo motor 492, so that the inner side of the clamping plate 494 contacts the periphery of the electrode body 491, and fix it.
[0047] The electrode body 491 is moved and rotated again by the action of the first servo motor 41 and the first hydraulic cylinder 46, so that the electrode body 491 is located at the top of the crystallizer 2. The first hydraulic cylinder 46 moves the electrode body to a suitable depth in the crystallizer. The crystallizer 2 is powered by an external power supply device, so that the electrode body 491 comes into contact with the arc igniter at the bottom of the crystallizer 2 to generate an electric arc. The high temperature generated by the electric arc gradually melts the surrounding slag and arc igniter. The lower end of the electrode body 491 melts under the action of resistance heat in the crystallizer 2 to form metal droplets, which can then be used for smelting.
[0048] When it is necessary to monitor the weight of the electrode body 491, the electrode body 491 is first moved upward in the crystallization under the action of the first hydraulic cylinder 46 and cooled for a period of time. Then, the fixed platform 42 at the top of the rotating rod 45 is rotated again by the first servo motor 41, and the fixed platform 42 rotates inside the fixed frame 44, so that the electrode body 491 rotates to the left and is on top of the weighing platform 51. The moving seat 47 is moved by the first hydraulic cylinder 46, so that the bottom of the electrode body 491 moves to the top of the weighing platform 51 and the weight sensor 52. The position of the limiting frame 56 is adjusted by the sliding adjustment of the connecting column 55 in the moving groove, and then fixed by the fixed shaft 54. The V-shaped limiting frame 56 contacts the outer periphery of the electrode body 491, which not only plays an auxiliary role in fixing the electrode, but also does not affect the normal weighing of the weight sensor 52. At the same time, the clamping plate 494 is released from fixing the electrode body 491 and is located on the outer periphery of the electrode body 491, further ensuring the stability of the electrode body 491.
[0049] The weight sensor 52 on the top of the weighing platform 51 can accurately monitor the weight of the electrode body 491 and, through electrical connection with the display screen 3, present the weight data to the operator intuitively, so that the operator can keep track of the consumption of the electrode at any time, so as to replace the electrode in time and avoid affecting the smelting process due to insufficient electrodes. At the same time, it can perform fine calculation on the wear of the electrode body 491 to ensure the quality of smelting.
[0050] In this application, the first hydraulic cylinder 46, the first servo motor 41, the second servo motor 492, and the weight sensor 52 need to be connected to the PLC controller near the electroslag furnace to ensure coordinated and automated operation of the equipment. The PLC controller is existing technology, and those skilled in the art are well aware of its operation steps, so it will not be described in detail here. The weight sensor 52 used is a Mettler Toledo MTB series.
[0051] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
