Description

Technical Field

[0001] The invention relates to the technical field of titanium alloy production, and in particular to a smelting device for smelting titanium alloy. Background Art

[0002] Titanium alloy is an alloy material with titanium as the main material and other metal materials added. In the production of titanium alloy, titanium alloy smelting equipment is needed to smelt it, and in order to avoid oxidation during the titanium alloy smelting process, smelting is generally carried out in a vacuum environment.

[0003] The existing titanium alloy smelting device generally sets a rotating structure in a vacuum-processed working box, fixes a crucible at the output end of the rotating structure, and then places raw materials in the crucible, heats the bottom of the crucible by a heating mechanism at the bottom of the crucible, melts the raw materials into a liquid state, completes the fusion, and then tilts the crucible through the rotating structure to pour the liquid raw materials into a mold in the working box. After the raw materials are cooled, the titanium alloy can be obtained. However, in actual operation, since the crucible is fixedly connected, it is not convenient to replace crucibles of different specifications. As a result, when too many raw materials need to be smelted, multiple operations are required, which reduces the work efficiency. After each smelting, waste slag will remain on the inner wall and bottom of the crucible, which is not convenient to enter the device for cleaning. As a result, in subsequent smelting, the residue and raw materials are mixed, which not only easily affects the smelting effect, but also easily produces harmful gases due to the different raw materials for the two smeltings, and even dangerous situations occur, reducing the practicability of the device.

[0026] The driving gear 13 and the lower gear ring 10 cooperate to transmit power to the driven gear 11 and the inner screw sleeve 7, and the inner screw sleeve 7 cooperates closely with the screw 8 through its internal threaded structure, ensuring the stable transmission of power, so that multiple screws 8 can rotate and move synchronously, and their coordinated action can drive the clamping block 9 to move toward the center with a uniform and stable force, so as to implement comprehensive and firm clamping and fixing of the outer side of the crucible placed in the device.

[0027] The telescopic rod 17 is introduced between the two groups of clamps 9, acting as a bridge connecting them into a whole. This design not only enhances the linkage between the clamps 9, but also enables the two groups of clamps 9 to maintain more consistent and coordinated movements when clamping the crucible, thereby greatly improving the stability and reliability of the clamping process. It can also effectively prevent the clamps 9 from unnecessary rotation during the rotation of the screw 8, further improving the stability and durability of the entire clamping system.

[0029] Put the titanium alloy raw material into the crucible, close the airtight door 42, and start the vacuum pump to evacuate the interior of the working box 2. The heating structure inside the main body 1 starts to work, and the high-temperature flame is sprayed to the bottom of the crucible through the nozzle 22 for heating.

After the raw material is melted into liquid and blended, the external motor is started to drive the turntable 3 to rotate, and through the upper plate 4 and the lower plate 5, the two fixed rings 6 and the crucible rotate together, and the liquid raw material is poured into the mold 21. After the liquid raw material is cooled and formed, the sealing door 43 is opened to take out the formed titanium alloy.

[0030] The bottom support ring 15 can provide a stable pre-support point for the crucible before clamping. This design not only greatly simplifies the clamping process, so that the clamping block 9 can more smoothly complete the clamping and fixation of the crucible, but also further enhances the stability and safety during clamping, ensuring that the crucible can maintain a stable posture under various operating conditions. The bottom support ring 15 and the heat collecting strip 16 are both made of high thermal conductivity materials. During the heating process, the fire column ejected from the nozzle 22 is surrounded by the heat collecting strip 16, and the heat collecting strip 16 can effectively intercept and absorb the heat scattered from the outside of the fire column. Subsequently, the absorbed heat is efficiently conducted to the crucible through the bottom support ring 15, realizing full utilization and efficient conversion of heat, which not only significantly reduces heat loss and improves energy utilization, but also improves the efficiency of crucible heating.

The side scraper blade 37 on the outside, with its sharp edge and perfect curvature, can easily scrape off the stubborn residue attached to the inner wall of the crucible, ensuring that every place is clean and free of residue. The design of the rotating structure 28 enables the vertical rod 30, the side scraper blade 37 and the telescopic blade 40 to rotate synchronously to clean the residue inside the crucible, avoiding its contact and reaction with subsequent raw materials, thereby ensuring the consistency and safety of the smelting effect, and effectively preventing the release of harmful substances, protecting the environment and the health of operators.

[0034] Through the design of the synchronization bar 39, the synchronous adjustment of the two outer sliding sleeves 34 and the two sets of rotating rods 35 is realized, which not only improves the efficiency and accuracy of the cleaning work, but also ensures the uniformity and consistency of the cleaning process. When cleaning crucibles of different specifications, it is only necessary to precisely control the No. 3 cylinder 38 and the synchronization bar 39 to achieve synchronous adjustment of the position of the side scraper blade 37 and the length of the telescopic blade 40, so as to adapt to crucibles of different sizes and perform efficient and thorough cleaning, which not only significantly improves the applicability and flexibility of the device, but also ensures stability during adjustment.
