Description

Technical Field

[0001] The embodiments of this utility model relate to an electroslag furnace, particularly to the field of large-tonnage gas-protected electroslag furnace technology, specifically to a frame-type gas-protected electroslag furnace. Background Technology

[0002] In existing technologies, traditional single-head, dual-station rotary electroslag furnaces rely solely on the furnace head's rotating support to bear the entire weight load. As the smelting tonnage of electroslag furnaces increases, when it exceeds 10 tons, the frequent arcing and heat release between the electrodes and the bottom plate during the arc initiation stage causes the furnace head to intermittently bear impact loads several times the weight of the electrodes. This dynamic load easily triggers a "head-drowning" phenomenon, causing the metal electrodes to deviate horizontally from the center of the crystallizer, thus creating a risk of arcing, and in severe cases, potentially damaging the crystallizer.

[0045] The frame-type gas-supported electroslag furnace described in this utility model has the following significant advantages compared with the traditional single-burner-head dual-station rotary gas-supported electroslag furnace:

[0046] 1. Structural Stability: The frame-type gas-supported electroslag furnace adopts a dual-load-bearing design of a rigid frame and a furnace head rotary support. The rigid frame load-bearing structure replaces the single rotary support, achieving multi-directional load distribution and possessing higher structural stability. This solves the problem of traditional single-furnace rotary electroslag furnaces where frequent arcing and heat release between the electrodes and the bottom plate during the arc initiation stage causes the furnace head to intermittently bear impact loads several times the weight of the electrodes. This dynamic load is prone to causing the furnace head to "drowsiness," resulting in horizontal displacement of the metal electrodes away from the center of the crystallizer, thus creating the risk of arcing, and in severe cases, potentially breaking down the crystallizer.

[0047] 2. Optimized rotation method: The design of the arc-shaped rotary track and the active and passive wheel sets moving in a rolling manner on the track replaces the method of using a rotary support frame to control the rotation movement. This solves the problems of frequent rotation of traditional single-head rotary electroslag furnaces, rapid wear of mechanical parts, and potential decrease in sealing performance during long-term operation.

[0048] 3. Stable electrical conductivity: The frame-type gas-supported electroslag furnace uses a conductive copper shaft device equipped with an electrode XY alignment device, which can precisely adjust the position between the metal electrode and the crystallizer, so that the metal electrode is always in the center of the crystallizer, avoiding electrode arcing, resulting in better electrical conductivity and ensuring the stability of the smelting process.

[0049] 4. Safe and convenient maintenance: The frame-type gas-sealed electroslag furnace is equipped with ladders and maintenance platforms with guardrails in multiple locations, allowing maintenance personnel to easily access the maintenance platform from the work platform. The ladder railings and maintenance platform railings ensure the safety of maintenance personnel during climbing and maintenance operations. This provides a safer working space and more convenient working conditions for the furnace's later maintenance.

[0050] 5. Reduced maintenance costs: The frame-type gas-insulated electroslag furnace adopts a dual-load-bearing design structure of rigid frame and furnace head rotation support, which can share the load-bearing capacity of the furnace head rotation support, extend the working life of mechanical parts in rotating parts, and reduce maintenance frequency and costs.

Detailed Implementation

[0059] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0060] The embodiments of this utility model relate to a frame-type gas-insulated electroslag furnace, such as... Figures 1 to 7 As shown, it includes:

[0061] A frame structure 100 is installed on the frame-type gas-insulated electroslag furnace; the frame structure 100 mainly serves a supporting function and realizes the function of safe and convenient maintenance.

[0062] A work platform 3 is set up within the frame structure 100; the work platform 3 serves as the work area when working.

[0063] The rotary track 22 is located above the work platform 3; the rotary track 22 is used to support the "C"-shaped frame structure 300 and plays a supporting role.

[0064] A C-shaped frame structure 300 is set on the rotary track 22;

[0065] Several smelting stations 200 are set below the “C”-shaped frame structure 300;

[0066] The “C”-shaped frame structure 300 switches between several smelting stations 200 along the rotary track 22.

[0067] When switching between smelting stations 200, multiple smelting stations 200 can work simultaneously, thereby improving smelting efficiency.

[0068] Compared to traditional single-head, dual-station rotary electroslag furnaces, the frame-type gas-supported electroslag furnace of this embodiment employs a dual-load-bearing design with a rigid frame 16 and a furnace head rotary support 6. The rigid frame load-bearing structure replaces the single rotary support, achieving multi-directional load distribution and providing higher structural stability. Through this reinforced rotary support system, the problem of frequent arcing and heat release between the electrodes and the base plate during the arc-starting stage in traditional single-head rotary electroslag furnaces is solved. This results in the furnace head intermittently bearing impact loads several times the weight of the electrodes. This dynamic load easily causes the furnace head to "drowsiness," leading to horizontal displacement of the metal electrodes away from the center of the crystallizer, thus creating the risk of arcing, and in severe cases, potentially damaging the crystallizer.

[0069] This embodiment replaces the method of using a rotary support frame to control the rotary motion by setting up an arc-shaped rotary track 22, an active wheel set 191 and a passive wheel set 192 to move in a rolling manner on the track. This solves the problems of frequent rotation, rapid wear of mechanical parts and possible deterioration of sealing in traditional single-head rotary electroslag furnaces.

[0070] This embodiment uses an electrode XY alignment device for the conductive copper shaft of a frame-type gas-supported electroslag furnace to precisely adjust the position between the metal electrode and the crystallizer, ensuring that the metal electrode is always in the center of the crystallizer, preventing electrode arcing, improving conductivity, and ensuring the stability of the smelting process.

[0071] This embodiment of the frame-type gas-supported electroslag furnace is equipped with ladders and maintenance platforms with guardrails in multiple locations, allowing maintenance personnel to easily access the maintenance platform from the work platform via the ladders. The ladder railings and maintenance platform railings ensure the safety of maintenance personnel during climbing and maintenance operations. This provides a safer working space and more convenient working conditions for the later maintenance of the furnace.

[0072] The frame-type gas-supported electroslag furnace in this embodiment adopts a dual-load-bearing design structure of rigid frame 16 and furnace head rotation support 6, which can share the load-bearing capacity of furnace head rotation support, extend the working life of mechanical parts in rotating parts, and reduce maintenance frequency and maintenance costs.

[0073] To achieve the aforementioned technical effects, the frame-type gas-supported electroslag furnace in this embodiment, such as Figures 1 to 7 As shown, the frame structure 100 also includes:

[0074] Equipment foundation 1 provides the foundation for the installation and load-bearing of the entire frame-type gas-insulated electroslag furnace.

[0075] The smelting station 20 is installed on the equipment foundation 1 and is fixed to the equipment foundation 1 by bolts. The smelting station 20 is equipped with a crystallizer, and the electroslag remelting process of the metal electrode is carried out in the crystallizer inside the smelting station 20.

[0076] The lower smoke hood 18 is located above the smelting station 20. The lower end of the lower smoke hood 18 is attached to the upper end of the smelting station 20, and the central axis of the lower smoke hood 18 coincides with the central axis of the smelting station 20.

[0077] The upper smoke hood 17 is located above the lower smoke hood 18, the lower end of the upper smoke hood 17 is in contact with the upper end of the lower smoke hood 18, and the central axis of the upper smoke hood 17 coincides with the central axis of the lower smoke hood 18.

[0078] The lower end of the work platform column 2 is installed on the equipment foundation 1 and is connected and fixed to the equipment foundation 1 by welding.

[0079] The work platform 3 is located above the work platform column 2 and is connected and fixed to several work platform columns 2 by welding.

[0080] The control room 4 is located above the work platform 3 and on one side of the smelting station 20.

[0081] The transformer room 5 is located directly above the control room 4.

[0082] To achieve the aforementioned technical effects, the frame-type gas-supported electroslag furnace in this embodiment, such as Figures 1 to 7 As shown, the "C"-shaped frame structure 300 also includes:

[0083] The rotary track 22 is set above the work platform 3 of the frame structure 100 and on the opposite side of the control room 4;

[0084] The rigid frame drive device 19 is located above the work platform 3. The driving wheel set 191 and the driven wheel set 192 of the rigid frame drive device 19 are both located on the rotary track 22. The rigid frame drive device 19 moves back and forth along the rotary track 22.

[0085] The rigid frame 16 is located above the rigid frame drive device 19 and is connected and fixed to the rigid frame drive device 19 by bolts;

[0086] The furnace head rotation support 6 is located above the working platform 3 and in front of the control room 4. One end of the furnace head rotation support 6 is connected and fixed to the working platform 3 by welding; the other end of the furnace head rotation support 6 is connected to the furnace head 7.

[0087] One side of the burner head 7 is connected and fixed to the rigid frame 16 by bolts, and the other side of the burner head 7 is connected and fixed to the burner head rotary support 6 by bolts; the burner head 7 is located above the upper smoke hood 17.

[0088] This structure consists of a rigid frame drive device 19, a rigid frame 16, a furnace head 7, and a furnace head rotary support 6, forming a "C"-shaped frame. The weight on the furnace head 7 can be supported by both the rigid frame 16 and the furnace head rotary support 6, resulting in higher structural stability. This solves the problems of the furnace easily tripping after the electrode is clamped, difficulty in adjusting the horizontal position of the metal electrode, and difficulty in keeping the metal electrode in the center of the crystallizer, which can cause arcing between the metal electrode and the crystallizer or even break through the crystallizer.

[0089] In addition, since the frame-type gas-supported electroslag furnace adopts a dual-load-bearing design structure of rigid frame 16 and furnace head rotary support 6, it can share the load-bearing capacity of furnace head rotary support 6, extend the working life of mechanical parts in the rotating part of furnace head rotary support 6, and reduce maintenance frequency and maintenance costs.

[0090] To achieve the aforementioned technical effects, the frame-type gas-supported electroslag furnace in this embodiment, such as Figures 1 to 7 As shown, it also includes:

[0091] The XY alignment device 24 is located on the upper end face of the furnace head 7. The XY alignment device 24 is connected to the conductive copper shaft 8 and precisely adjusts the position of the conductive copper shaft 8 in the X and Y directions.

[0092] A-frame 9 is positioned above the XY alignment device 24;

[0094] The conductive copper shaft 8 is located below the lifting drive device 10. An electrode clamping mechanism 81 is provided at the end of the conductive copper shaft 8.

[0095] Because the frame-type gas-supported electroslag furnace provided in this embodiment uses a conductive copper shaft device and is equipped with a conductive copper shaft XY centering device, the position between the metal electrode clamped by the conductive copper shaft and the crystallizer can be precisely adjusted and controlled during the smelting process, so that the metal electrode is always in the center of the crystallizer, reducing arc fluctuations, improving conductivity, and ensuring a stable smelting process.

[0096] To achieve the aforementioned technical effects, the frame-type gas-supported electroslag furnace in this embodiment, such as Figures 1 to 7 As shown, it also includes:

[0097] The first ladder 14 is located between the work platform 3 and the furnace head maintenance platform on the upper surface of the rigid frame 16, on the outside of the rigid frame 16, and is fixed to the rigid frame 16 by bolts. The upper half of the first ladder 14 is equipped with a guardrail.

[0098] The first fence 13 is installed on the upper surface of the rigid frame 16 and is fixed to the rigid frame 16 by bolts. The first fence 13 encloses the furnace head maintenance work platform on the upper surface of the rigid frame 16 into a closed area.

[0099] The second ladder 12 is located between the maintenance work platform on the upper surface of the rigid frame 16 and the maintenance work platform on the upper part of the A-frame 9, situated on one side of the A-frame 9, and is connected and fixed to the A-frame 9 via a triangular fixing frame. The upper half of the second ladder 12 is equipped with a guardrail.

[0100] The second fence 11 is installed on the upper surface of the maintenance work platform on the A-frame 9, enclosing the maintenance work platform on the A-frame 9 into a closed area. The maintenance work platform on the A-frame 9 is connected and fixed to the A-frame 9 by a triangular fixing frame.

[0101] Because the frame-type gas-supported electroslag furnace provided by this utility model is equipped with ladders with guardrails and maintenance work platforms with railings in multiple locations, maintenance personnel can easily access the furnace head maintenance work platform from the work platform via the ladders, and from the furnace head maintenance work platform to the maintenance work platform on the upper part of the A-frame. At the same time, the guardrails on the ladders and the railings on the maintenance platforms ensure the safety of maintenance personnel during climbing and maintenance work. This structural design provides a safer working space and more convenient working conditions for the later maintenance of the furnace.

[0103] The lower furnace leg 21 is installed on the equipment foundation 1 and is fixed to the equipment foundation 1 by bolts;
