Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a melting device for the production of titanium-nickel alloy. Background Technology

[0002] In the production process of titanium-nickel alloys, the melting device is the core equipment that determines the quality and performance of the alloy. Because titanium-nickel alloys are very prone to chemical reactions with oxygen, nitrogen and other gases in the air at high temperatures, generating hard and brittle phase impurities, which significantly reduces the strength, plasticity and corrosion resistance of the alloy. Therefore, the sealing performance of the furnace body of the melting device becomes a key factor in ensuring the purity and quality of the alloy.

[0003] Currently, the most common sealing structures for titanium-nickel alloy melting equipment furnaces on the market are flange seals and threaded connections. When using a flange seal, a circular flange needs to be installed at the top opening of the furnace body, and the flange is fastened to the furnace body with a large number of bolts. Although this sealing method can achieve a good sealing effect, during the installation and disassembly of the flange, operators need to tighten or loosen a large number of bolts one by one. This not only consumes a lot of time and manpower, but also makes the operation process cumbersome. Especially in production scenarios where crucibles need to be changed frequently, it greatly reduces production efficiency. At the same time, the use of a large number of bolts can easily lead to uneven stress. If a bolt is not tightened enough or becomes loose, it will cause the seal to fail, which will affect the vacuum degree or inert gas protective atmosphere inside the furnace. This will cause the titanium-nickel alloy to oxidize during the melting process, affecting product quality and reducing the practicality and flexibility of the equipment. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a melting device for titanium-nickel alloy production. This device addresses the issue that the furnace body sealing structure mainly relies on flange sealing and threaded connection sealing. When using flange sealing, a circular flange needs to be installed at the top opening of the furnace body, and a large number of bolts are used to fasten the flange to the furnace body. While this sealing method can achieve a good sealing effect, during the installation and disassembly of the flange, operators need to tighten or loosen a large number of bolts one by one. This not only consumes a lot of time and manpower, but also makes the operation process cumbersome. Especially in production scenarios where frequent crucible changes are required, this greatly reduces production efficiency. Furthermore, the use of a large number of bolts can easily lead to uneven stress. If a bolt is not tightened enough or becomes loose, it will cause the seal to fail, thus affecting the vacuum degree or inert gas protective atmosphere inside the furnace. This can cause oxidation of the titanium-nickel alloy during the melting process, affecting product quality and reducing the practicality and flexibility of the equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a melting device for titanium-nickel alloy production, comprising a furnace body, a sealing cover, and a crucible, wherein three limiting components are provided on the furnace body;

The outer walls of the two protruding plates are provided with fixed rod grooves. A fixed rod is fixedly installed on the lower outer wall of the movable limiting rod.

[0007] The sealing cover has three movable limit rod grooves on its upper surface. Each of the three movable limit rod grooves has a first limit block groove inside. The lower surface of the upper end of the movable limit rod has a second limit block groove. A limit block is slidably connected inside the second limit block groove. A rotating threaded rod is threadedly connected to the outer wall of the upper end of the movable limit rod. All three limit components are installed on the outer wall of the upper end of the furnace body.

[0008] Preferably, the movable limiting rod is L-shaped, the two fixed rod grooves are inclined, and the outer walls of the two ends of the lower fixed rod of the two movable limiting rods are slidably connected to the grooves at the lower ends of the corresponding protrusions.

[0009] The outer wall of the sealing ring at the lower end of the sealing cover contacts the inner wall at the upper end of the furnace body.

[0010] Preferably, the outer walls of both ends of the fixing rod are slidably connected to the interior of the corresponding fixing rod groove;

[0011] The upper outer wall of the movable limit rod is slidably connected to the inner side of the corresponding movable limit rod groove.

[0030] Please see Figure 1-4 This utility model provides a technical solution: a melting device for titanium-nickel alloy production, comprising a furnace body 1, a sealing cover 2, and a crucible 11;

[0031] Three limit components are provided on the furnace body 1;

[0032] The limiting assembly includes a movable limiting rod 5, a fixed base 7, and two protruding plates 6. Both protruding plates 6 are fixedly connected to the outer wall of the fixed base 7, which is fixedly installed on the upper outer wall of the furnace body 1. The lower outer wall of the sealing cover 2 is slidably connected to the inner upper part of the furnace body 1. The movable limiting rod 5 is L-shaped. The outer walls of both protruding plates 6 are provided with fixed rod grooves 9, which are inclined. The outer walls of the lower fixed rods of the two movable limiting rods 5 are slidably connected to the corresponding grooves on the lower ends of the protruding plates 6. The outer wall of the sealing ring at the lower end of the sealing cover 2 contacts the inner upper wall of the furnace body 1. A fixed rod 8 is fixedly installed on the lower outer wall of the movable limiting rod 5, and the outer walls of the two fixed rods 8 are slidably connected to the inner parts of the corresponding fixed rod grooves 9. Three movable limiting rod grooves are provided on the upper surface of the sealing cover 2. The groove 10 has a first limiting block groove 12 inside each of the three movable limiting rod grooves 10. The upper outer wall of the movable limiting rod 5 is slidably connected to the interior of the corresponding movable limiting rod groove 10. The lower surface of the upper end of the movable limiting rod 5 has a second limiting block groove 13. The interior of the second limiting block groove 13 is slidably connected to a limiting block 14. The end of the limiting block 14 near the first limiting block groove 12 extends slidably into the interior of the movable limiting rod groove 10 and contacts the inner wall of the corresponding first limiting block groove 12. The upper outer wall of the movable limiting rod 5 is threadedly connected to a rotating threaded rod 4. The end of the rotating threaded rod 4 near the limiting block 14 extends threadedly into the interior of the second limiting block groove 13 and is rotatably connected to the upper surface of the limiting block 14. All three limiting components are installed on the upper outer wall of the furnace body 1.

[0033] Among them, a gas inlet pipe 3 is fixedly installed on the upper surface of the sealing cover 2. The interior of the gas inlet pipe 3 is connected to the interior of the furnace body 1. The outer wall of the crucible 11 is slidably connected to the interior of the furnace body 1. A control panel 15 is fixedly installed on the upper outer wall of the furnace body 1. The control panel 15 is electrically connected to the electrodes on the lower outer wall of the furnace body 1.

[0034] Furthermore, when using this device, specifically the melting device for titanium-nickel alloy production, firstly, the crucible 11 is placed inside the furnace body 1, then the titanium-nickel alloy raw material is placed into the crucible 11. Next, the sealing cover 2 is slid downwards along the upper interior of the furnace body 1, so that the sealing ring at the lower end of the sealing cover 2 is in close contact with the inner wall of the upper end of the furnace body 1, achieving a preliminary seal. At this time, the movable limiting rod 5 is flipped, and the movable limiting rod 5, through the lower fixed rod and the groove on the protruding plate 6, allows the upper end of the movable limiting rod 5 to enter the interior of the movable limiting rod slide groove 10. Then, the operator rotates the threaded rod 4, causing the limiting block 14 to slide in the second limiting block groove 13, pushing the limiting block 14 out of the second limiting block groove 13, so that one end of it near the first limiting block groove 12 slides and extends into the interior of the movable limiting rod slide groove 10, further pressing the sealing cover 2 onto the furnace body 1, achieving a seal between the sealing cover 2 and the furnace body 1. After the furnace body 1 is tightly fixed, protective gas is introduced into the furnace body 1 through the gas inlet pipe 3 to prevent the titanium-nickel alloy raw material from being oxidized during the melting process. Then, the operator sets the working parameters of the furnace body 1 through the control panel 15. The control panel 15 controls the electrodes on the lower outer wall of the furnace body 1 to work, so that the furnace body 1 is heated and melted. After the titanium-nickel alloy raw material is melted, the sealing cover 2 needs to be removed. First, rotate the threaded rod 4 in the opposite direction to pull the limiting block 14 out of the first limiting block groove 12 and back into the second limiting block groove 13 to release the lock on the movable limiting rod 5. Then, flip and pull the movable limiting rod 5 to disengage it from the movable limiting rod slide groove 10 and release the fixation on the sealing cover 2. Finally, remove the sealing cover 2 from the furnace body 1. After the crucible 11 cools down, the molten titanium-nickel alloy is taken out.

[0035] By rotating the threaded rod 4 in the limiting assembly in the opposite direction, the limiting block 14 is pulled out from the first limiting block groove 12 and returned to the second limiting block groove 13, thus releasing the lock on the movable limiting rod 5. Then, the movable limiting rod 5 is flipped and pulled to disengage from the movable limiting rod slide groove 10, thereby releasing the fixation on the sealing cover 2. Finally, the sealing cover 2 is removed from the furnace body 1. This method of disassembling the sealing cover 2 is simple and quick, effectively reducing the workload of the staff while improving the disassembly efficiency of the sealing cover 2.
