Description
Technical Field
[0001] This invention belongs to the field of titanium-iron ingot production technology, specifically relating to a continuous demolding production line and method for titanium-iron ingots. Background Technology
[0002] In ferrotitanium ingot casting production lines, molten metal flows into the ingot mold and is cooled, initially shaping the ferrotitanium ingot. A demolding device then separates the ingot from the mold, allowing the molten metal to be poured again within the mold. However, after cooling, the ferrotitanium ingot remains sticky to the mold, sometimes failing to detach smoothly. Partial or complete detachment can occur, and if it re-enters the casting area, the high-temperature molten metal poured into the mold containing the ingot can overflow, potentially injuring workers. Furthermore, if the ingot is delayed in detaching into the equipment, it can jam operating equipment or injure nearby workers. Current production lines often use manual hammering to demold the ingot, but this prevents unmanned and efficient operation. Therefore, improving the success rate of one-time demolding, optimizing the manual demolding process, and increasing the automation level of the production line are pressing issues. Summary of the Invention
[0003] The technical problem to be solved by this invention is to address the shortcomings of the prior art by providing a continuous demolding production line for titanium-iron ingots. The material storage and cooling rack allows the molten titanium-iron ingots in the mold to be cooled for a long time without occupying the material transfer platform, making it easier to successfully demold the ingots in one go, thus ensuring production safety. The vibration isolation flip plate drives the mold to flip and demold the ingots, avoiding damage to the rotation control mechanism under high-frequency vibration, which helps to extend its service life and further promotes the unmanned and efficient operation of the titanium-iron ingot production line.

[0014] The above-mentioned continuous demolding production line for titanium-iron ingots is characterized in that: it further includes an electrical control system, the electrical control system including a controller, a material dropping detection sensor installed on the ingot mold flipping and material dropping frame, and a height detection sensor group installed on the gantry traveling frame for detecting the height of the ingot mold hanging frame, the height detection sensor group including a low-position detection sensor, a middle-position detection sensor and a high-position detection sensor arranged sequentially from bottom to top.
[0015] Meanwhile, this invention also discloses a simple method for continuous demolding production of ferro-titanium ingots that improves the success rate of one-time demolding. The method comprises the following steps:
[0016] Step 1: Transfer the first batch of molten material from the smelting furnace to the storage cooling rack.
[0017] Step 101: Place multiple blank ingot molds on both the material transfer platform and the material storage cooling rack. The material transfer platform transports the multiple blank ingot molds on it to the material discharge port of the smelting furnace to receive the material, so that the multiple blank ingot molds are evenly distributed and carry the first batch of molten material, becoming blank ingot molds with material. The sum of the volumes of the multiple blank ingot molds on the material transfer platform is equal to the volume of the first batch of molten material.
[0018] Step 102: The material transfer platform transports multiple ingot molds carrying the first batch of molten material to the tail of the storage and cooling rack. The area at the tail of the storage and cooling rack where the material transfer platform is temporarily parked is designated as the waiting area. The gantry crane truss replaces the multiple ingot molds carrying the first batch of molten material on the material transfer platform in the waiting area with the multiple ingot molds without material on the storage and cooling rack.
[0019] Step 2: Transfer the i-th furnace charge to the waiting area.
[0020] The material transfer platform returns from the waiting area to the smelting furnace discharge port, so that the multiple empty ingot molds on the material transfer platform are evenly distributed and receive the molten material of the i-th furnace to become ingot molds with material. Then the material transfer platform transports the multiple ingot molds with material carrying the molten material of the i-th furnace to the waiting area for the initial cooling of the molten material of the i-th furnace; where i is a positive integer greater than or equal to 2.
[0021] Step 3: Perform the charging operation for the (i-1)th furnace charge:
[0022] Step 301: At time T before the (i+1)th furnace melts, the gantry crane truss transfers any one of the ingot molds carrying the (i-1)th furnace melt on the storage cooling rack to the ingot mold support seat on the ingot mold flipping and tapping rack for tapping; where T is the sum of the time it takes for multiple ingot molds carrying material on the storage cooling rack to be tapped into multiple blank ingot molds and to be replaced by multiple ingot molds carrying material on the material transfer platform, and the time it takes for the material transfer platform to move from the waiting area to the unloading port;
[0023] Step 302: After the material tapping is completed, the gantry crane truss transfers the empty ingot mold on the ingot mold flipping and tapping frame to the empty ingot mold support seat on the material storage and cooling frame;
[0024] Repeat steps 301 to 302 until all the ingot molds on the storage cooling rack are empty ingot molds that have been chipped.
[0025] Step 4: Perform secondary cooling of the i-th furnace charge:
[0026] The gantry crane truss replaces multiple ingot molds carrying the i-th furnace of molten material on the material transfer platform in the waiting area with multiple empty ingot molds on the material storage and cooling rack, so that all the ingot molds on the material storage and cooling rack are ingot molds carrying the i-th furnace of molten material, and performs secondary cooling of the i-th furnace of molten material.
[0027] Step 5: Return to step 2 and continue the continuous demolding production of titanium-iron ingots.
[0028] The above-mentioned continuous demolding production method for titanium-iron ingots is characterized in that the specific process of material tapping in step 301 is as follows:
[0029] Step s1: After the vibration isolation flap drives the ingot mold carrying material to flip and knock off the material, the material dropping detection sensor detects whether there is material passing through.
[0030] If yes, proceed to step s2; otherwise, the vibration isolation flap drives the ingot mold with unfinished material to reset, and the vibration isolation flap drives the ingot mold to flip and discard material again. This cycle continues until the titanium-iron ingot in the current ingot mold is demolded; then proceed to step s2.
[0031] Step s2: At this point, the ingot mold with material is successfully de-materialized and becomes an empty ingot mold. The vibration isolation flap drives the empty ingot mold to reset, completing the de-materialization process.
[0032] Compared with the prior art, the present invention has the following advantages:
[0033] 1. The ferro-titanium ingot continuous demolding production line of the present invention, by setting up a storage cooling rack as an intermediate bearing platform, allows the molten ferro-titanium ingot in the ingot mold to be cooled for a long time without occupying the material transfer platform, so that the melting in the smelting furnace can be continuous and uninterrupted, thereby improving production efficiency. At the same time, the ferro-titanium ingot that has been cooled for a long time is more likely to be successfully knocked off in one go, thereby ensuring production safety.
[0034] 2. The titanium-iron ingot continuous demolding production line of the present invention uses a vibration isolation flap to drive the ingot mold to flip and knock off the material. At the same time, the ingot mold is supported by a buffer spring bracket to absorb the impact force and does not come into direct contact with the rotation control mechanism, thereby achieving vibration isolation and avoiding damage to the rotation control mechanism under high-frequency vibration, which helps to extend its service life.
[0035] 3. The method of the present invention is simple in steps. By implementing secondary cooling and detecting material dropping with a dropping sensor, the success rate of one-time demolding of titanium iron ingots is improved, and the ingot mold with material is prevented from returning to the material transfer platform, thereby further promoting the unmanned and efficient operation of titanium iron ingot production lines.
[0036] In summary, the material storage and cooling rack of the present invention allows the molten titanium-iron ingot in the ingot mold to be cooled for a long time without occupying the material transfer platform, making it easier to successfully drop the ingot in one go, thereby ensuring production safety; the vibration isolation flip plate drives the ingot mold to flip and drop the ingot, avoiding damage to the rotation control mechanism under high-frequency vibration, which helps to extend its service life, thereby further promoting the unmanned and efficient operation of the titanium-iron ingot production line.

[0045] like Figures 1 to 5 As shown, the present invention provides a continuous demolding production line for titanium-iron ingots, comprising a material transfer platform 1, a material storage and cooling rack 2, an ingot mold flipping and tapping rack 3, and a material unloading and transfer trolley 4 arranged sequentially, as well as a gantry crane truss 5; the gantry crane truss 5 is used to move ingot molds 6 between the material transfer platform 1, the material storage and cooling rack 2, and the ingot mold flipping and tapping rack 3; the number of ingot molds 6 stored on the material storage and cooling rack 2 is not less than the number of ingot molds 6 stored on the material transfer platform 1;
[0046] The ingot mold flipping and tapping frame 3 includes an ingot mold flipping mechanism and a tapping mechanism. The tapping mechanism includes an ingot mold support base 7, a tapping beam 8 disposed on the front side of the ingot mold support base 7, and a buffer spring bracket disposed on the rear side of the ingot mold support base 7. Before the ingot mold 6 is flipped, it is supported by the ingot mold support base 7 and the buffer spring bracket. After the ingot mold 6 is flipped, it collides with the tapping beam 8. Two operating handles 9 are fixedly disposed on both sides of the ingot mold 6, and the operating handles 9 are resting on the ingot mold support base 7.
[0047] The ingot mold flipping mechanism includes two flipping control units respectively disposed on both sides of the ingot mold 6. The flipping control unit includes a vibration isolation flip plate 10, a telescopic driver that drives the vibration isolation flip plate 10 to move closer to or away from the ingot mold 6, and a rotation control mechanism that drives the vibration isolation flip plate 10 to rotate. The vibration isolation flip plate 10 has an elongated arc-shaped hole 11 through which one operating handle 9 passes and a through hole 12 into which another operating handle 9 extends. The arc of the elongated arc-shaped hole 11 is greater than π / 2.
[0048] In this embodiment, after the ingot mold 6 is flipped and inverted, its rear sidewall collides with the material-discharging beam 8, and the titanium iron ingot falls from the space between the material-discharging beam 8 and the ingot mold support seat 7 onto the material-discharging and transfer trolley 4 below, thus completing the material discharge.
[0049] It should be noted that the two flip control units work synchronously. The arc of the elongated arc hole 11 is greater than π / 2. After the vibration isolation flip plate 10 drives the ingot mold 6 to reset, the ingot mold 6 is supported by the buffer spring bracket to dissipate the impact force and does not contact the bottom hole wall of the elongated arc hole 11, that is, it does not contact the rotation control mechanism, thus achieving vibration isolation.
[0050] It should be noted that when the vibration isolation flap 10 approaches the ingot mold 6, simultaneously, one operating handle 9 on the ingot mold 6 passes through the elongated arc hole 11, and the other operating handle 9 extends into the through hole 12. At this time, the operating handle 9 extending into the through hole 12 serves as the pivot when the ingot mold 6 flips, ensuring the stability of the ingot mold 6 when it flips.
[0051] In this embodiment, the vibration isolation flap 10 is a fan-shaped plate.
[0052] In this embodiment, both the material storage cooling rack 2 and the material transfer platform 1 are provided with rows of ingot mold support seats 7. The multiple ingot mold support seats 7 on the material storage cooling rack 2 and the material transfer platform 1 are at the same height, and the number of ingot mold support seats 7 on the material storage cooling rack 2 is not less than the number of ingot mold support seats 7 on the material transfer platform 1.
[0053] In this embodiment, the material transfer platform 1 includes an electric cart and an audible and visual alarm installed on the electric cart. The ingot mold support 7 is installed on the electric cart. The upper surface of the electric cart is provided with a fireproof and heat-insulating layer, which includes heat-insulating cotton and refractory bricks to prevent the high-temperature molten liquid in the ingot mold from splashing and damaging the electric cart.
[0054] In this embodiment, the ingot mold support 7, the material tapping beam 8, and the buffer spring bracket are all mounted on the material tapping frame 20. The base plate of the material tapping frame 20 is a ground plate, which is fixed to the ground by anchor bolts to ensure the overall stability of the material tapping mechanism.
[0055] In this embodiment, the two operating handles 9 are symmetrically arranged along the vertical axis of symmetry of the side surface of the ingot mold 6 to ensure the stability of the ingot mold 6 during transportation.
[0056] In this embodiment, the end of the operating handle 9 away from the ingot mold 6 is fitted with an anti-detachment sleeve to prevent the ingot mold 6 from swaying left and right and detaching from the ingot mold support 7.
[0057] In this embodiment, the rotation control mechanism includes a rotating shaft 13 that drives the vibration isolation flap 10 to rotate, a sleeve 14 that slides with the rotating shaft 13 through a linear spline, and a reduction motor 15 that drives the sleeve 14 to rotate through a transmission assembly. The rotating shaft 13 is coaxially arranged with the through hole 12. The transmission assembly includes a drive gear 16 that is driven to rotate by the reduction motor 15 and a driven gear 18 that is connected to the drive gear 16 through a chain 17. The driven gear 18 is fixedly sleeved on the sleeve 14.
[0058] It should be noted that the rotation control mechanism is mounted on the rotation control mounting bracket 19, which is located on both sides of the material feeding frame 20.
[0059] In this embodiment, a bearing seat 21 is fixedly installed on the rotation control mounting bracket 19, and the sleeve 14 rotates in conjunction with the bearing seat 21.
[0060] In this embodiment, the telescopic actuator includes a push-pull force transmission plate 22 sleeved on the rotating shaft 13 and a drive cylinder 23 disposed on both sides of the push-pull force transmission plate 22 and driving it to move. The push-pull force transmission plate 22 and the rotating shaft 13 are rotatably connected through a bearing 24.
[0061] In this embodiment, one of the telescopic actuators includes two drive cylinders 23, which are respectively disposed on both sides of the bearing seat 21. The cylinder body of the drive cylinder 23 is mounted on the rotation control mounting bracket 19. The telescopic rod of the drive cylinder 23 is connected to the push-pull force transmission plate 22 by bolts to ensure the smooth movement of the push-pull force transmission plate 22. At the same time, it balances the force on the push-pull force transmission plate 22, avoids lateral force on the linear spline, reduces the wear of the linear spline, and thus ensures the normal interaction and cooperation between the sleeve 14 and the rotating shaft 13.
[0062] It should be noted that by setting the bearing 24 to rotatably connect the push-pull force transmission plate 22 and the rotating shaft 13, the push-pull force transmission plate 22 can drive the rotating shaft 13 and the vibration isolation flap 10 to move closer to or further away from the ingot mold 6, while not affecting the rotation of the rotating shaft 13 to drive the vibration isolation flap 10 to rotate.
[0063] In this embodiment, the ingot mold support base 7 includes two support ear bases 25 respectively disposed on both sides of the ingot mold 6, and the support ear base 25 is provided with a first groove 26 for locking the operating handle 9.
[0064] In this embodiment, the operating handle 9 is a cylindrical operating handle, and the first groove 26 is a semi-circular groove. The operating handle 9 can rotate within the semi-circular groove, but cannot move forward or backward.
[0065] In this embodiment, the buffer spring bracket includes multiple spring support units arranged in rows at the bottom of the ingot mold 6. Each spring support unit includes a buffer spring 28 and a protective cylinder 27 sleeved on the outside of the buffer spring 28. The top of the protective cylinder 27 is lower than the top of the buffer spring 28.
[0066] In this embodiment, the protective cylinder 27 is fixedly mounted on the material feeding frame 20 and does not move with the ingot mold 6; the buffer spring 28 is an orange rectangular compression spring with a large compression stroke, which greatly reduces the impact on the ingot mold support 7 when the ingot mold 6 flips and resets, and extends the service life of the ingot mold support 7.
[0067] It should be noted that the protective cylinder 27 also limits the compression stroke of the buffer spring 28, preventing the buffer spring 28 from being over-compressed and damaged. At the same time, it prevents the ingot mold 6 from overturning and bumping into the isolation flap 10 due to excessive vibration.
[0068] In this embodiment, a hemispherical buffer pad is provided on the top of the buffer spring 28 to further achieve buffering.
[0069] In this embodiment, the upper surface of the material-feeding beam 8 is a slope that slopes downward toward the mold support 7, with an inclination angle of 5° to 10°.
[0070] In this embodiment, the two ends of the material-receiving beam 8 are embedded in the material-receiving frame 20, and the force-bearing points at both ends are provided with supporting reinforcing ribs to improve impact resistance.
[0071] In this embodiment, the inclination angle of the upper surface of the ejector beam 8 is 8°. This relatively small inclination angle results in a larger impact when the ingot mold 6 strikes the ejector beam 8 after flipping. This facilitates smooth demolding of the material within the ingot mold 6. Simultaneously, the lateral force decreases while the vertical force increases, significantly reducing lateral impact and causing deformation to occur longitudinally. Reinforcing crossbeams are installed at both longitudinal ends of the ejector beam 8, minimizing the impact of deformation on its strength. Furthermore, as the ingot mold 6 impacts the top of the inclined surface of the ejector beam 8, the angle gradually decreases, further enhancing demolding capability.
[0072] In this embodiment, the gantry crane truss 5 includes a gantry traveling frame 29 and a mold hanging frame set on the gantry traveling frame 29. The gantry traveling frame 29 is provided with lifting screws 30 on both sides for driving the mold hanging frame to rise and fall. The mold hanging frame includes a crossbeam 31 driven to rise and fall by the lifting screws 30 and two hanging arms 32 symmetrically arranged below the crossbeam 31. The bottom of the hanging arm 32 is provided with a support ear plate 33, and a second groove 34 that cooperates with the operating handle 9 is provided on the support ear plate 33.
[0073] A guide block 35 is provided between the support ear plate 33 and the side wall of the hanging arm 32. The guide block 35 is arranged on the side of the second groove 34, and the upper surface of the guide block 35 has a guide slope that faces the second groove 34 and is inclined downward.
[0074] In this embodiment, the distance between the two supporting ear plates 33 is greater than the length of the ingot mold 6 and less than the distance between the far ends of the two operating handles 9 on both sides of the ingot mold 6, so that the ingot mold hanger can pick up the ingot mold 6 from the operating handles 9 for transportation.
[0075] It should be noted that when the lifting position of the hanging arm 32 deviates from the front and rear position of the operating handle 9 on the ingot mold 6, the guide block 35 plays a guiding role, guiding the operating handle 9 into the second groove 34 to prevent the ingot mold 6 from falling off during gripping and lifting.
[0076] In this embodiment, the supporting ear plate 33 and the supporting ear seat 25 have the same structure but different installation positions.
[0077] In this embodiment, guide posts 36 are also provided on both sides of the lifting screw 30. The guide posts 36 pass through the crossbeam 31 to guide it, so that the force is more evenly distributed when the ingot mold hanger is raised and lowered, ensuring the stability of the overall structure. Specifically, when the ingot mold 6 is misaligned or uneven, the lifting screw 30 only bears the vertical force, while the other lateral forces are borne by the guide posts 36, thereby ensuring the integrity and stability of the structure.
[0078] In this embodiment, the material unloading and transfer trolley 4 is an electric flatbed trolley with a guardrail.
[0079] In this embodiment, the gantry traveling frame 29 runs on the first ground rail 37, and the material transfer platform 1 and the unloading and transfer trolley 4 run on the second ground rail 38. The track spacing of the first ground rail 37 is greater than that of the second ground rail 38, and the equipment running on the first ground rail 37 and the second ground rail 38 do not affect each other.
[0080] In this embodiment, an electrical control system is also included. The electrical control system includes a controller, a material dropping detection sensor 42 installed on the ingot mold flipping and material dropping frame 3, and a height detection sensor group installed on the gantry traveling frame 29 for detecting the height of the ingot mold hanging frame. The height detection sensor group includes a low-position detection sensor 39, a middle-position detection sensor 40, and a high-position detection sensor 41 arranged from bottom to top.
[0081] In this embodiment, when the low-position detection sensor 39 detects the ingot mold hanger, the support ear plate 33 of the ingot mold hanger is located below the ingot mold 6 operating handle 9 on the material storage cooling rack 2 or the material transfer platform 1. At this time, the ingot mold hanger can lift the ingot mold 6 from bottom to top.
[0082] The high station corresponding to the high station detection sensor 41 is the ingot mold transfer station. When the high station detection sensor 41 detects the ingot mold hanger, the ingot mold hanger can move the ingot mold 6 on it to above any ingot mold support seat 7 on the material transfer platform 1, the material storage cooling rack 2, or the ingot mold flipping and tapping rack 3.
[0083] The intermediate station corresponding to the intermediate station detection sensor 40 is the material tapping station. When the ingot mold hanger with the ingot mold 6 on it moves to the ingot mold support seat 7 of the ingot mold flipping and tapping frame 3, the lifting screw 30 drives the ingot mold hanger to fall until the intermediate station detection sensor 40 detects the ingot mold hanger. At this time, the ingot mold 6 has been placed on the ingot mold support seat 7 of the ingot mold flipping and tapping frame 3, and the ingot mold hanger is separated from the ingot mold 6.
[0084] In this embodiment, the material dropping detection sensor 42, the low-position detection sensor 39, the medium-position detection sensor 40, and the high-position detection sensor 41 are all diffuse reflection type sensors.
[0085] In this embodiment, the crossbeam 31 is provided with an extension plate that cooperates with the height detection sensor group for detection by the height detection sensor group.
[0086] In this embodiment, the material dropping detection sensor 42 is installed on the side wall of the material dropping frame 20 to detect whether there are titanium iron ingots falling into the space between the material dropping beam 8 and the ingot mold support seat 7. When the amount of material dropping reaches the maximum load capacity of the material dropping and transfer trolley 4, the material dropping and transfer trolley 4 moves forward along the second ground rail 38 to dump the material, and then returns to the receiving area to receive the material.
[0087] In this embodiment, there are four material dropping detection sensors 42, with two on each side of the material dropping frame 20. When two material dropping detection sensors 42 simultaneously detect an object, it indicates that demolding is successful. This design can avoid false detection and also avoid false detection of vibration parameters during material dropping. It can also more accurately detect the falling off of the titanium iron ingot, preventing the titanium iron ingot from being undetected after falling off or the material from being falsely detected as falling off.
[0088] A method for continuous demolding production of ferrotitanium ingots, the method comprising the following steps:
[0089] Step 1: Transfer the first batch of molten material from the smelting furnace to the storage cooling rack.
[0090] Step 101: Place multiple blank ingot molds 6 on both the material transfer platform 1 and the material storage cooling rack 2. The material transfer platform 1 transports the multiple blank ingot molds 6 to the material discharge port of the smelting furnace to receive the material, so that the multiple blank ingot molds 6 are evenly distributed and carry the first batch of molten material, becoming blank ingot molds 6 with material; the sum of the volumes of the multiple blank ingot molds 6 on the material transfer platform 1 is equal to the volume of the first batch of molten material.
[0091] Step 102: The material transfer platform 1 transports multiple ingot molds 6 carrying the first furnace of molten material to the tail of the material storage and cooling rack 2. The area at the tail of the material storage and cooling rack 2 where the material transfer platform 1 is temporarily parked is designated as the waiting area. The gantry crane truss 5 replaces the multiple ingot molds 6 carrying the first furnace of molten material on the material transfer platform 1 in the waiting area with the multiple ingot molds 6 without material on the material storage and cooling rack 2.
[0092] Step 2: Transfer the i-th furnace charge to the waiting area.
[0093] The material transfer platform 1 returns from the waiting area to the smelting furnace discharge port, so that the multiple empty ingot molds 6 on the material transfer platform 1 are evenly distributed and receive the molten material of the i-th furnace to become ingot molds 6 with material. Then the material transfer platform 1 transports the multiple ingot molds 6 with material carrying the molten material of the i-th furnace to the waiting area for the initial cooling of the molten material of the i-th furnace; where i is a positive integer greater than or equal to 2.
[0094] Step 3: Perform the charging operation for the (i-1)th furnace charge:
[0095] Step 301: At time T before the (i+1)th furnace of molten material melts, the gantry crane truss 5 transfers any one of the ingot molds 6 carrying the (i-1)th furnace of molten material on the storage cooling rack 2 to the ingot mold support seat 7 on the ingot mold flipping and tapping rack 3 for tapping; where T is the sum of the time when multiple ingot molds 6 carrying material on the storage cooling rack 2 have completed tapping and become multiple ingot molds 6 without material, and have completed the replacement with multiple ingot molds 6 carrying material on the material transfer platform 1, and the time when the material transfer platform 1 moves from the waiting area to the unloading port;
[0096] Step 302: After the material tapping is completed, the gantry crane truss 5 transfers the empty ingot mold 6 on the ingot mold flipping and tapping rack 3 to the empty ingot mold support seat 7 on the material storage and cooling rack 2.
[0097] Repeat steps 301 to 302 until all the ingot molds 6 on the storage cooling rack 2 are empty ingot molds 6 after the material has been removed;
[0098] Step 4: Perform secondary cooling of the i-th furnace charge:
[0099] The gantry crane truss 5 replaces multiple ingot molds 6 carrying the i-th furnace molten material on the material transfer platform 1 in the waiting area with multiple empty ingot molds 6 on the material storage and cooling rack 2, so that all the ingot molds 6 on the material storage and cooling rack 2 are ingot molds carrying the i-th furnace molten material, and performs secondary cooling of the i-th furnace molten material.
[0100] Step 5: Return to step 2 and continue the continuous demolding production of titanium-iron ingots.
[0101] In this embodiment, T=30min.
[0102] It should be noted that the multiple blank ingot molds 6 placed on the material transfer platform 1 are just enough to receive a batch of molten material melted in one go by the smelting furnace.
[0103] It should be noted that the initial and secondary cooling methods for the molten material in the ingot mold 6 on the material storage cooling rack 2 are both natural cooling at room temperature.
[0104] It should be noted that the secondary cooling and the detection of the material dropping sensor 42 provide a dual guarantee for a high success rate of one-time demolding of titanium iron ingots.
[0105] In this embodiment, the specific process of material tapping in step 301 is as follows:
[0106] Step s1: After the vibration isolation flap 10 drives the ingot mold 6 carrying material to flip and knock off the material, the material dropping detection sensor 42 detects whether there is material passing through.
[0107] If yes, proceed to step s2; otherwise, the vibration isolation flap 10 drives the ingot mold 6 with unfinished material to reset, and the vibration isolation flap 10 drives the ingot mold 6 to flip and discard material again. This cycle continues until the titanium-iron ingot in the current ingot mold 6 with material is demolded; then proceed to step s2.
[0108] Step s2: At this time, the ingot mold 6 with material is successfully de-materialized and becomes an ingot mold 6 without material. The vibration isolation flap 10 drives the ingot mold 6 without material to reset, completing the de-materialization process.
[0109] Specifically, during the material tapping operation, the gantry traveling frame 29 uses the encoder absolute position positioning method for positioning. The pre-set positioning points of the gantry traveling frame 29 include: the material tapping positioning point corresponding to the ingot mold support seat 7 on the ingot mold flipping material tapping frame 3, the starting positioning point of the gantry traveling frame 29 behind the waiting area, multiple cooling rack positioning points matching multiple ingot mold support seats 7 on the material storage cooling rack 2, and multiple transfer platform positioning points matching multiple ingot mold support seats 7 on the material transfer platform 1.
[0110] In this embodiment, five ingot mold support seats 7 are provided on the material storage cooling rack 2, and four ingot mold support seats 7 are provided on the material transfer platform 1. The ingot mold support seats 7 and the positioning points are arranged from front to back. Initially, the fifth ingot mold support seat 7 on the material storage cooling rack 2 is empty, and the other four ingot mold support seats 7 hold four empty ingot molds. After the empty ingot molds on the four ingot mold support seats 7 on the material transfer platform 1 are filled with material, they return to the vicinity of the material storage cooling rack 2. The diffuse reflection sensor detects that the material transfer platform 1 has arrived in place, and the ingot mold replacement procedure can begin.
[0111] At the start of the process, the gantry crane 29 is at the initial positioning point, and the ingot mold holder is located at the low position corresponding to the low position detection sensor 39. It then moves to the first transfer platform positioning point on the material transfer platform 1, lifting the ingot mold with material from the ingot mold support seat 7 corresponding to the first transfer platform positioning point until the high position detection sensor 41 detects the ingot mold holder. Afterward, the gantry crane 29 moves to the fifth cooling rack positioning point on the storage cooling rack 2, lowering the ingot mold with material onto the ingot mold support seat 7 corresponding to the fifth cooling rack positioning point. Subsequently, the gantry crane truss 5 moves to the fourth cooling rack positioning point on the storage cooling rack 2, lifting the empty ingot mold corresponding to the fourth cooling rack positioning point to the high position, and then returns to the first transfer platform positioning point on the material transfer platform 1, lowering the empty ingot mold onto the ingot mold support seat 7 corresponding to that transfer platform positioning point. This completes the transfer of the first ingot mold with material. This process is repeated until all four ingot molds with material on the material transfer platform 1 have been transferred to the storage cooling rack 2.
[0112] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the present invention. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present invention shall still fall within the protection scope of the present invention.
