Description

Technical Field

[0001] The invention relates to the technical field of alloy smelting furnaces, in particular to high-purity titanium smelting equipment. Background Art

[0002] In order to obtain high-purity titanium metal, chemical methods are usually used to obtain metal of a certain purity first, and then physical methods are used to achieve a higher purity. Due to its high activity and high temperature characteristics, the smelting of titanium metal requires a special process to avoid oxidation and contamination. The commonly used smelting method in the existing technology is to use vacuum induction technology, which uses electromagnetic induction eddy currents to heat titanium materials, with precise temperature control and reduced oxidation.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0034] A high purity titanium smelting equipment, such as Figure 1As shown, it includes a smelting furnace 1, a furnace cover 2 for cooperating in closing is rotatably connected to the top of the smelting furnace 1, an induction smelting mechanism 3 for assisting smelting is rotatably connected to the inner side of the smelting furnace 1, a smelting bearing mechanism 4 for controlling the working state is arranged at the bottom end of the induction smelting mechanism 3, a lifting base 5 for controlling the working state of the smelting bearing mechanism 4 is installed at the bottom end of the smelting furnace 1, a protective tube 6 for cooperating in controlling the lifting base 5 is also fixedly connected to the bottom end of the smelting furnace 1, a turret support 7 for assisting smelting is fixedly installed on the outer side of the furnace cover 2, and a working controller 8 for cooperating with the turret support 7 is arranged at the end of the turret support 7 away from the furnace cover 2.

[0035] The smelting furnace 1 comprises a furnace body 10 , a furnace door 11 is rotatably connected to the front end of the furnace body 10 , a resistance wire bracket 12 is fixedly installed inside the furnace body 10 , and a heat-releasing resistance wire 13 is fixedly installed inside the resistance wire bracket 12 .

[0036] The smelting process is carried out in the space inside the furnace body 10. A vacuum needs to be maintained during the process to ensure that the products of the smelting process will not affect the smelting of metallic titanium, thereby ensuring the smelting quality of metallic titanium. The furnace door 11 is used to maintain the vacuum in the furnace body 10 cavity during the smelting process, and can be opened when discharging is required to facilitate discharging. The resistance wire bracket 12 inside the furnace body 10 is used to install the exothermic resistance wire 13. The exothermic resistance wire 13 is used to maintain heat during the pouring and discharging of liquid metallic titanium, so as to avoid the low temperature on the outside during the pouring and discharging process affecting the state of the molten high-purity titanium.

[0037] like Figure 5 As shown, a hanging tube 21 is fixedly installed at the top inner side of the furnace cover 2, a hanging plate 22 is movably installed at the bottom end of the hanging tube 21, a plurality of lifting and moving grooves 23 are arranged in an array inside the hanging plate 22, a moving hook 24 is slidably arranged inside each lifting and moving groove 23, and the moving hook 24 passes through the lifting and moving groove 23 and is fixedly connected with a closed baffle 25.

[0038] The suspension plate 22 is supported by the suspension tube 21 on the inner side of the furnace cover 2 , so that the multiple lifting and moving grooves 23 on the inner side of the suspension plate 22 can cooperate with the suspension moving hooks 24 and the closing baffle 25 .

[0039] like Figure 2 and Figure 3 As shown, the induction melting mechanism 3 includes an induction coil 30 , and coil mounting plates 31 are fixedly mounted on both ends of the outer side of the induction coil 30 , and a rotating shaft 32 is fixedly mounted on one end of the coil mounting plate 31 away from the induction coil 30 .

[0040] The smelting support mechanism 4 includes a smelting crucible 40 , a smelting tank 41 is arranged at the top of the smelting crucible 40 corresponding to the position of the closed baffle 25 , a crucible support seat 42 is fixedly installed at the bottom of the smelting crucible 40 , and a bearing bracket 43 is arranged at one end of the crucible support seat 42 away from the smelting crucible 40 .

[0041] By passing an alternating current through the induction coil 30 to form an alternating magnetic field, the blank inside the melting crucible 40 generates eddy currents due to electromagnetic induction, and the blank inside the melting crucible 40 is heated by Joule heat to achieve melting. The coil mounting plates 31 located at both ends of the outer side of the induction coil 30 are used to rotate in conjunction with the rotating shaft 32, so that the induction coil 30 can drive the internal melting crucible 40 to rotate, thereby adjusting the position and state of the melting crucible 40 and pouring out the liquid metal titanium after melting inside.

[0042] The crucible support seat 42 and the bearing bracket 43 at the bottom of the melting crucible 40 are used to support the melting crucible 40 and also to drive the melting crucible 40 to rotate to achieve centrifugal melting, so as to further purify the metal titanium inside.

[0043] like Figure 2 and Figure 3 As shown, a driving motor 51 is fixedly connected to the top of the lifting base 5, and the output end of the driving motor 51 passes through the bottom side wall of the smelting furnace 1 and is connected to a rotating wheel 52. A lifting cylinder 53 is arranged at the bottom end of the lifting base 5, and a cylinder push plate 54 is fixedly connected to the output end of the lifting cylinder 53. The lifting cylinder 53 outputs air to the cylinder push plate 54 to push the lifting base 5 to move up and down.

[0044] When the driving motor 51 and the rotating wheel 52 need to be put into use, the lifting cylinder 53 is used to drive the cylinder push plate 54, and the cylinder push plate 54 pushes the lifting base 5, so that the rotating wheel 52 can cooperate with the bearing bracket 43 to drive the melting crucible 40 to rotate, and the driving motor 51 at the top of the lifting base 5 drives the rotating wheel 52 to rotate, so that the rotating wheel 52 drives the bearing bracket 43 at the top to rotate, and the crucible support seat 42 is driven by the bearing bracket 43 to rotate, and the rotation is achieved during the melting process to meet the centrifugal requirements of centrifugal melting. The external control driving motor 51 is used to drive the speed to change, and different melting is achieved at different stages of melting. In the refining stage of melting, the speed is controlled at 100rpm, combined with the existing electromagnetic stirring, to promote the melting process of high-purity titanium, gather and remove internal inclusions, and can effectively reduce the oxygen content compared with the melting method in the prior art. When the temperature fluctuates, the speed is reduced, and after the temperature returns to stability, it is adjusted to 120rpm to enhance the purification effect.

[0045] like Figure 3 and Figure 4As shown, the protection tube 6 is opened at the bottom end of the smelting furnace 1, the outer side of the protection tube 6 is connected to a side connecting tube 61, the end of the side connecting tube 61 away from the protection tube 6 is connected to a material receiving barrel 63, the inner side of the protection tube 6 is slidably connected to a material receiving cup 62, the top of the material receiving cup 62 is fixedly connected to a movable sealing baffle, an air bag 64 is fixedly installed on the top of the material receiving barrel 63, the end of the air bag 64 away from the material receiving barrel 63 is fixedly installed on the bottom end of the lifting base 5, a first reaction substrate 65 is arranged on the inner side of the material receiving cup 62, and a second reaction substrate 66 is arranged on the inner side of the material receiving barrel 63.

[0046] During the vacuum induction melting process, the interior of the furnace body 10 is usually maintained in a vacuum state by an external vacuum pump. During the melting process, some impurities will vaporize and produce waste gas, which is normally discharged through the vacuum pump. However, in special circumstances, such as when the vacuum pump is damaged, the internal vacuum degree will be affected, resulting in the inability to discharge the internal gaseous impurities, which affects the internal high-purity titanium. At this time, due to the decrease in vacuum degree, the pressure inside the protective tube 6 increases, and the material cup 62 will no longer be able to be maintained at one end close to the interior of the furnace body 10 by pressure, but will move to the bottom end. When it moves to the material cup 62 and the side connecting pipe 61 is connected, the first reaction substrate 65 inside the material cup 62 will contact and react with the second reaction substrate 66 inside the material barrel 63 to produce a large amount of gas. In the actual implementation process, the first reaction substrate 65 can be selected from compressed acetic acid gas, and the second reaction substrate 66 can be selected from common reaction substrates in the prior art, such as sodium bicarbonate and sodium azide, which can generate a large amount of gas through multiple chemical reactions generated inside, so that the airbag 64 expands, pushes the lifting base 5 to the top, and allows the lifting base 5 to move to the top through the driving motor 51 and the rotating wheel 52, so that the smelting crucible 40 can pass through the top smelting tank 41 and the closed baffle 25 to form a pipeline channel, so as to avoid the gaseous impurities that have been filled in the furnace body 10 from affecting the purity of the liquid titanium metal, and to ensure the purity of the titanium metal to a certain extent. At the same time, a common pressure sensor in the prior art can be selected to monitor the internal environment, and cooperate with the alarm to promptly alarm the outside, reminding the production management personnel to handle the inside of the furnace body 10.

[0047] like Figure 6 As shown, a turret shaft 71 is fixedly installed at one end of the turret bracket 7 away from the smelting furnace 1, a built-in shaft is arranged inside the turret shaft 71, a turret connecting frame 72 is fixedly connected to the outer side of the built-in shaft, the turret connecting frame 72 is a trident shape, and a temperature measuring tower 73, a feeding tower 74 and a sampling tower 75 are fixedly installed on the three forks respectively, and control push plates are arranged on the outer sides of the temperature measuring tower 73, the feeding tower 74 and the sampling tower 75, and the positions of the control push plates on the outer sides of the three are arranged in sequence from low to high.

[0048] The turret shaft 71 directly controls the rotation of the turret bracket 7 to control the position of the furnace cover 2, which is convenient for controlling the interior. The internal shaft controls the turret connecting frame 72 to rotate, so that the different temperature measuring towers 73, charging towers 74 and sampling towers 75 outside the turret connecting frame 72 are respectively introduced into the furnace body 10 through the hanging pipe 21 at the top of the furnace cover 2 according to actual needs, and the corresponding internal conditions are processed, including monitoring the internal temperature, charging the interior according to the smelting state, and sampling the internal samples according to different smelting states to analyze the smelting effect.

[0049] like Figure 8 As shown, the feeding tower 74 includes a feeding lifting rod 741, the bottom end of the feeding lifting rod 741 is fixedly connected to a feeding connecting rod 742, the bottom end of the feeding connecting rod 742 is fixedly connected to a movable bottom plate 745, a feeding port is penetrated through the bottom end of the movable bottom plate 745, a feeding fixed plate 744 is arranged on the top of the movable bottom plate 745, and a feeding barrel 743 is fixedly connected to the outer side of the feeding fixed plate 744.

[0050] The lifting and lowering of the feeding tower 74 is controlled by adjusting the position of the feeding lifting rod 741, and the feeding connecting rod 742 is used to drive the movable bottom plate 745 at the bottom to rotate, so that the movable bottom plate 745 rotates, and the drop opening opened at the bottom of the movable bottom plate 745 moves from the bottom of the feeding fixed plate 744 to the bottom of the feeding barrel 743, so that the internal added material can fall from the feeding barrel 743 through the drop opening, and finally be guided to the inner side of the smelting crucible 40 inside the furnace body 10 through the hanging plate 22.

[0051] like Figure 7 As shown, the sampling tower 75 includes a sampling lifting rod 751, the bottom end of which is fixedly connected to a sampling storage barrel 752, a lifting guide rail 753 is arranged outside the sampling storage barrel 752, and the bottom end of the lifting guide rail 753 is fixedly connected to a sampling closing plate 754.

[0052] The lifting and lowering of the entire sampling tower 75 is controlled by the position of the sampling lifting rod 751, and the sampling closing plate 754 is placed inside the liquid metal. Sampling is performed by cooperating with the sampling closing plate 754 and the lifting guide rail 753. During the sampling process, the sample is protected to a certain extent inside the sampling storage barrel 752 to prevent the external environment from having an adverse effect on the internal sample and affecting the sampling and detection results.

[0053] like Figure 8As shown, a rotating rod 81 for controlling rotation is provided at the bottom end of the working controller 8, a bladeless fan 82 is fixedly installed on the outside of the working controller 8, a signal rod 83 is fixedly connected to one end of the outside of the working controller 8 facing the turret bracket 7, and corresponding auxiliary push plates are provided on the outside of the signal rod 83 at the position of the control push plates on the outside of the temperature measuring tower 73, the feeding tower 74 and the sampling tower 75. A rotating base plate is fixedly installed on the bottom end of the rotating rod 81, and a raw material barrel 84 and a sampling analysis table 85 are respectively installed on the top of the rotating base plate.

[0054] The corresponding working states are controlled by the control push plates on the outside of the temperature measuring tower 73, the feeding tower 74 and the sampling tower 75 and the corresponding auxiliary push plates on the outside of the signal rod 83; when the control push plate on the outside of the temperature measuring tower 73 pushes the corresponding auxiliary push plate on the outside of the signal rod 83, the bladeless fan 82 is started to blow air into the temperature measuring tower 73, and the outside air is used to control the temperature inside the temperature measuring tower 73 to protect the temperature measuring tower 73; when the control push plate on the outside of the feeding tower 74 pushes the corresponding auxiliary push plate on the outside of the signal rod 83, the rotating rod 81 is rotated to drive The raw material barrel 84 moves to the bottom of the bladeless fan 82, so that the feeding tube 743 inside the feeding tower 74 falls into the corresponding raw material barrel 84 to take the material, so that the material can be correctly collected by the feeding tube 743, which is convenient for subsequent feeding processing; when the control push plate on the outside of the sampling tower 75 pushes the corresponding auxiliary push plate on the outside of the signal rod 83, the rotating rod 81 rotates to drive the sampling analysis table 85 to move to the bottom of the bladeless fan 82, and the sample taken by the sampling closing plate 754 is placed inside the sampling analysis table 85, so that the sampling analysis table 85 can analyze the obtained sample.

[0055] When in use, firstly, the turret support 7 is controlled to drive the furnace cover 2 to move, so that the staff can place the raw materials to be processed in the melting crucible 40 inside the furnace body 10, and then close the furnace cover 2, and heat the inside of the melting crucible 40 by controlling the induction coil 30 to carry out conventional melting work; and the temperature measuring tower 73, the feeding tower 74 and the sampling tower 75 at the top of the turret support 7 can be connected with the furnace cover 2 to achieve different working requirements. The temperature measuring tower 73 is used to measure the internal temperature, so that the staff can monitor the internal working state; the feeding cylinder 743 inside the feeding tower 74 is used to feed the inside of the melting crucible 40 to assist in the corresponding melting; the sampling storage barrel 752 inside the sampling tower 75 cooperates with the sampling closing plate 754 to carry out sampling operations during the melting process, so that the melting staff can analyze the melting effect.

[0056] Through the interaction between the auxiliary push plate outside the signal rod 83 and the control push plate corresponding to the temperature measuring tower 73, the bladeless fan 82 is controlled to blow gas to the top, the temperature of the temperature measuring tower 73 is adjusted, and the service life of the temperature measuring tower 73 is protected.

[0057] Through the interaction between the auxiliary push plate outside the signal rod 83 and the control push plate corresponding to the feeding tower 74, the raw material barrel 84 is controlled to provide corresponding materials, and the feeding tower 74 is assisted to perform the feeding work.

[0058] Through the interaction between the auxiliary push plate outside the signal rod 83 and the control push plate corresponding to the sampling tower 75, the sampling analysis platform 85 is controlled to receive and process the samples taken by the sampling tower 75, so as to facilitate the staff to analyze the smelting status.

[0059] During refining, the lifting cylinder 53 can be used to drive the cylinder push plate 54 to control the lifting base 5 to lift, so that the rotating wheel 52 driven by the driving motor 51 can cooperate with the bearing bracket 43 at the bottom of the melting crucible 40, so that the melting crucible 40 can rotate during the melting process, and drive the liquid melt inside the melting crucible 40 to perform centrifugal melting. The lifted melting crucible 40 forms a smelting chamber of the suspension tube 21-melting crucible 40 through the cooperation of the melting tank 41 and the closed baffle 25, which can prevent the liquid melt from flowing out of the melting crucible 40 when the bottom driving mechanism has problems and the speed is out of control, and prevent the melt from being contaminated. The conventional smelting scheme is to promote the homogenization of the components through electromagnetic stirring, while the centrifugal smelting scheme proposed in this application can use the centrifugal force generated by the rotation to accelerate the floating and separation of certain gas impurities and mixed impurities in the liquid melt, which can effectively reduce the oxygen content in the melt and reduce microscopic segregation such as β spots. Compared with the conventional smelting scheme in the prior art, it has a better smelting effect. The driving motor 51 and the rotating wheel 52 may also be replaced by magnetic bearings in the prior art that are more suitable for use in a vacuum environment, thereby better reducing the adverse effects caused by physical friction and improving stability.

[0060] The vacuum degree inside the furnace body 10 is maintained by connecting an external vacuum pump to the outside of the furnace body 10. At this time, the receiving cup 62 inside the protection tube 6 will block the connection between the protection tube 6 and the side connecting tube 61 due to the influence of the internal pressure. When the vacuum pump connected to the furnace body 10 that maintains the internal vacuum has a problem and causes the internal vacuum degree to decrease, the receiving cup 62 inside the protection tube 6 will slowly fall as the internal vacuum degree decreases and the pressure increases, until the receiving cup 62 can no longer block the connection between the protection tube 6 and the side connecting tube 61, allowing the first reaction substrate 65 to enter the inside of the receiving barrel 63 through the side connecting tube 61. At this time, the first reaction substrate 65 inside the receiving cup 62 will contact the second reaction substrate 66 inside the receiving barrel 63 and react to produce a large amount of gas. A large amount of gas will fill the inside of the airbag 64 and push the lifting base 5 at the top of the airbag 64 to move toward the top. At this time, the melting crucible 40 is pushed to move to the top by the driving motor 51 and the rotating wheel 52. The melting groove 41 at the top of the melting crucible 40 cooperates with the closed baffle 25 to form a cavity to prevent the large amount of exhaust gas filling the inside of the furnace body 10 from polluting the melt of the metallic titanium, providing a certain degree of protection, and cooperating with the internal sensors and alarms to alarm the outside to remind the staff to take corresponding measures.
