Description

Technical Field

[0001] This utility model belongs to the field of steel coil production technology, specifically, it relates to a high-temperature annealing base plate for oriented silicon steel. Background Technology

[0002] Grain-oriented silicon steel is a core soft magnetic material for critical electrical equipment such as power transformers and large motors, and its magnetic properties require extremely high performance. High-temperature annealing is an indispensable key step in the production process of grain-oriented silicon steel, which aims to eliminate processing stress, promote preferred grain orientation, and significantly improve performance indicators such as magnetic permeability.

[0003] While welded base plates offer a secure connection, damage such as deformation or material deterioration makes removal extremely difficult, often requiring specialized cutting equipment, which is time-consuming, labor-intensive, and can easily damage the annealed plate support structure. Replacing the base plate with a new one necessitates meticulous grinding and adjustment of the welded areas, severely impacting production continuity. Bolted base plates, while theoretically removable, are prone to rust and seizing under repeated exposure to high temperatures. Disassembly requires significant time to clean the threads and apply excessive torque, increasing worker fatigue.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

[0005] To address the problems of welded base plates, which, while providing a stable connection, are extremely difficult to remove once damaged (e.g., deformed, or deteriorated), often requiring specialized cutting equipment—a time-consuming and labor-intensive process that can damage the annealed plate support structure—and the need for fine grinding and adjustment of welded areas after replacement, which severely impacts production continuity, this invention addresses these issues. While bolted base plates are theoretically removable, bolts are prone to corrosion and seizing under repeated exposure to high temperatures. Disassembly requires significant time for thread cleaning and excessive torque application, increasing worker workload. The basic concept of this invention is as follows:

[0006] A high-temperature annealed base plate made of grain-oriented silicon steel includes an annealed plate support;

[0007] A support leg is fixedly connected to the bottom end of the annealing plate support. The annealing plate support has an internal disassembly and assembly mechanism, which includes a layering mechanism. The disassembly and assembly mechanism includes a movable groove formed in the inner wall of the annealing plate support.

[0008] A slot is provided on one side of the inner wall of the bottom of the movable groove. A permanent magnet is fixedly connected to the inner wall of the slot away from the movable groove. A locking rod is fixedly connected to the outer wall of the permanent magnet. A magnetic locking block is movably disposed on the inner wall of the slot. A locking hole is provided on the outer wall of the magnetic locking block. The outer wall of the locking rod is locked in the inner wall of the locking hole. An annealing plate is fixedly connected to the outer wall of the magnetic locking block. A disassembly locking hole is provided at the top of the annealing plate.

[0009] In a preferred embodiment of the present invention, the layered mechanism includes an anti-adhesion substrate layer disposed on the top surface of the annealing plate, a high-efficiency thermally conductive intermediate layer disposed below the anti-adhesion substrate layer, and a buffer protective layer disposed on the top surface of the anti-adhesion substrate layer.

[0010] In a preferred embodiment of this utility model, there are two permanent magnets, which are distributed in a symmetrical structure inside the annealing plate support. The permanent magnets are made of high-temperature resistant permanent magnets.

[0011] In a preferred embodiment of this utility model, there are two magnetic card blocks, which are distributed in a symmetrical structure on the outer wall of the annealing plate.

[0012] In a preferred embodiment of this utility model, the outer wall of the magnet block is fitted to the inner wall of the slot, and the outer wall of the lever is fitted to the inner wall of the hole.

[0013] In a preferred embodiment of this utility model, the anti-adhesion substrate layer is made of special ceramic material.

[0014] In a preferred embodiment of this utility model, the high-efficiency thermally conductive intermediate layer is constructed by carbon nanotubes and synergistic metals.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] This invention involves aligning the magnetic locking block on the outer wall of the annealing plate with the movable slot at the top of the annealing plate support, inserting its outer wall into the slot, and then pushing the annealing plate downwards. The magnetic locking block will then move downwards along the inner wall of the movable slot until it reaches the bottom and lands at the opening of the slot. A pry bar can then be used to rotate the annealing plate clockwise, causing the magnetic locking block to rotate clockwise and engage with the slot. As rotation continues, the magnetic locking block gradually approaches the permanent magnet, and the locking hole on its outer wall aligns with the locking rod, allowing it to be inserted into the outer wall of the rod. Simultaneously, the magnetic locking block and the permanent magnet form a magnetic attraction limit. Through the cooperation of the slot, permanent magnet, locking rod, magnetic locking block, and locking hole, the annealing plate can be installed with its limit function. This eliminates the need for welding and bolts, making assembly and disassembly more convenient and unaffected by high temperatures.

[0017] This invention eliminates the possibility of adhesion and chemical reaction between the substrate layer and the silicon steel sheet from the material source, ensuring the smooth and intact surface of the silicon steel sheet. The highly efficient heat-conducting intermediate layer can rapidly absorb and evenly distribute heat from the heating source, causing the entire base plate surface to heat up quickly, helping the silicon steel sheet achieve a rapid and uniform heating state, and significantly reducing the annealing time. The buffer protective layer can play a buffering role to prevent the silicon steel sheet from being scratched and maintain the integrity of the silicon steel sheet surface.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0026] like Figures 1 to 4As shown, a high-temperature annealed base plate of oriented silicon steel includes an annealed plate support 1 and a support leg 2 fixedly connected to the bottom end of the annealed plate support 1. The annealed plate support 1 is provided with a disassembly and assembly mechanism 31. The disassembly and assembly mechanism 31 is provided with a layering mechanism 32. The disassembly and assembly mechanism 31 includes a movable groove 311 opened in the inner wall of the annealed plate support 1. A slot 312 is opened on one side of the inner wall of the bottom end of the movable groove 311. A permanent magnet 313 is fixedly connected to the inner wall of the slot 312 away from the movable groove 311. A locking rod 314 is fixedly connected to the outer wall of the permanent magnet 313. A magnetic locking block 316 is movably disposed in the slot 312. A locking hole 317 is opened on the outer wall of the magnetic locking block 316. The outer wall of the locking rod 314 is locked in the inner wall of the locking hole 317. An annealed plate 315 is fixedly connected to the outer wall of the magnetic locking block 316. A disassembly locking hole 318 is opened at the top of the annealed plate 315.

[0027] Furthermore, there are two permanent magnets 313, which are distributed symmetrically inside the annealed plate support 1. The permanent magnets 313 are made of high temperature resistant permanent magnets, which ensures that the permanent magnets 313 can withstand high temperatures and will not lose their magnetic effect due to high temperatures.

[0028] Furthermore, there are two magnetic clips 316, which are distributed symmetrically on the outer wall of the annealing plate 315. This allows for synchronous and uniform support on both sides of the annealing plate 315, thereby further improving the installation and support stability of the annealing plate 315.

[0029] Furthermore, the outer wall of the magnetic card block 316 fits snugly against the inner wall of the card slot 312, and the outer wall of the card rod 314 fits snugly against the inner wall of the card hole 317. This ensures a tight fit between the outer wall of the magnetic card block 316 and the inner wall of the card slot 312, thereby improving the stability of the magnetic card block 316 during the snap-fit ​​support process.

[0030] The layered structure 32 includes an anti-adhesion substrate layer 321 disposed on the top surface of the annealing plate 315, a high-efficiency thermally conductive intermediate layer 322 disposed below the anti-adhesion substrate layer 321, and a buffer protective layer 323 disposed on the top surface of the anti-adhesion substrate layer 321.

[0031] Furthermore, the anti-adhesion substrate layer 321 is made of special ceramic material, which combines the stability of alumina ceramic with the high temperature resistance of silicon carbide ceramic, thus eliminating the possibility of adhesion and chemical reaction with silicon steel sheet from the source.

[0032] Furthermore, the highly efficient thermally conductive intermediate layer 322 is constructed from carbon nanotubes and synergistic metals, which allows it to quickly absorb heat, thereby significantly reducing the annealing time and improving annealing efficiency.

[0033] The implementation principle of a high-temperature annealed base plate of oriented silicon steel in this embodiment is as follows: When installing the annealed plate 315, firstly, a special pry bar is inserted into the disassembly clip 318. Then, the magnetic clip 316 on the outer wall of the annealed plate 315 is aligned with the movable groove 311 opened at the top of the annealed plate support 1, and its outer wall is inserted into it. Then, the annealed plate 315 is pushed downward. At this time, the magnetic clip 316 will move downward on the inner wall of the movable groove 311 until the magnetic clip 316 moves to the bottom of the movable groove 311. At the same time, the magnetic clip 316 will fall into the opening of the slot 312. Then, the pry bar can be pushed to drive the annealed plate 315 to rotate clockwise. At this time, the annealed plate 315 will drive the magnetic clip 316 to rotate clockwise, so that its outer wall rotates and engages inside the slot 312. As the rotation continues, the magnetic clip 316 will gradually approach the permanent magnet 313. At the same time, the magnetic clip 316 will... The locking hole 317 on the outer wall of the 6th plate will align with the locking rod 314, thus inserting into the outer wall of the locking rod 314. At the same time, the magnetic locking block 316 will form a magnetic attraction limit with the permanent magnet 313. In this way, the locking and installation of the annealing plate 315 can be completed through the cooperation of the locking groove 312, the permanent magnet 313, the locking rod 314, the magnetic locking block 316 and the locking hole 317. During disassembly, the operator only needs to insert the pry bar into the disassembly locking hole 318 and rotate it counterclockwise to rotate the annealing plate 315, thereby causing the magnetic locking block 316 to overcome the magnetic force between it and the permanent magnet 313 and disengage. Then, continue to rotate so that the magnetic locking block 316 moves to the bottom of the movable groove 311, and then moves the annealing plate 315 upward, so that the outer wall of the magnetic locking block 316 disengages from the inner wall of the movable groove 311. This eliminates the need for welding and bolt installation, making disassembly and assembly more convenient, and it is not affected by high temperature.

[0034] The anti-adhesion substrate layer 321 is made of a special ceramic material. This composite ceramic combines the high chemical stability of alumina ceramic with the excellent high temperature resistance and high strength of silicon carbide ceramic. It can withstand high temperatures up to 1600℃, eliminating the possibility of adhesion and chemical reaction with the silicon steel sheet from the material source, and ensuring the smooth and intact surface of the silicon steel sheet. A high-efficiency thermally conductive intermediate layer 322 is tightly attached below the anti-adhesion substrate layer 321. The carbon nanotubes, with their ultra-high axial thermal conductivity, work together with the metal to form a high-efficiency heat conduction channel, which can rapidly absorb and evenly distribute the heat from the heating source, causing the entire base plate surface to heat up rapidly. This helps the silicon steel sheet achieve a rapid and uniform heating state, greatly reducing the annealing time. A nano-ceramic coating is coated on top of the anti-adhesion substrate layer 321 as a buffer protective layer 323. The nano-ceramic coating particles are small and dense, which can further fill the tiny pores that may exist in the substrate layer and enhance the flatness of the base plate surface. Moreover, its flexibility is improved compared to the substrate ceramic. When the silicon steel sheet deforms due to thermal expansion and contraction, it can play a buffering role, prevent the silicon steel sheet from being scratched, and maintain the integrity of the silicon steel sheet surface.
