Description

Technical Field

[0001] This invention relates to the field of anode product manufacturing equipment, and in particular to a novel ground casting track trolley production line system. Background Technology

[0002] In the electrolytic aluminum anode assembly process, after the steel claws are removed from the residual anode and the ferrophosphorus ring, they undergo straightening, cleaning, graphite dipping, drying, and meshing processes before needing to be cast with a ferrophosphorus solution. The current casting process layout consists of a horizontal parallel arrangement of the casting station production line, casting trolley, and intermediate frequency furnace, forming a one-to-one "locked" relationship. One intermediate frequency furnace can only serve one casting production line, resulting in a rigid system. In production, the current solution has weak risk resistance; if any node on the production line fails, the entire line shuts down, and the equipment utilization rate is low. Casting is an intermittent operation, while intermediate frequency furnace melting is continuous. This combination leads to situations where the intermediate frequency furnace wastes energy during casting intervals or the casting trolley waits for the ferrophosphorus solution, resulting in suboptimal equipment utilization. Further increasing casting capacity would require replicating an entire system, including the intermediate frequency furnace, which involves high investment costs, large footprint, and is difficult to implement when space is limited. Therefore, the current casting station production line layout is not ideal and requires further optimization. Summary of the Invention

[0003] The purpose of this invention is to provide a novel ground casting track trolley production line system to solve the problems of existing technologies that involve replicating a complete system including an intermediate frequency furnace, which has high investment costs, large footprint, and is difficult to implement when space is limited.

[0004] The technical solution of this invention: A novel ground casting track trolley production line system, comprising an intermediate frequency furnace, a casting controller, a single-anode casting production line, and a double-anode casting production line.

[0005] The intermediate frequency furnace is provided with a transverse transfer track on one side, and a first furnace front railcar and a second furnace front railcar are provided on the upper side of the transverse transfer track.

[0006] At least two sets of longitudinal transfer tracks are provided between the single-anode casting production line and the double-anode casting production line and the transverse transfer track, and at least one set of transfer cars are provided on the longitudinal transfer track.

[0007] A casting track is provided between the single-anode casting production line and the double-anode casting production line and the longitudinal transfer track, and a casting car is provided on the casting track;

[0008] The positions of the first furnace front railcar, the second furnace front railcar, the transfer car and the casting car are transmitted wirelessly via a wireless signal receiver, and the wireless signal receiver integrates the signals and then transmits them to the casting controller.

[0009] The transverse transfer track, the longitudinal transfer track, and the casting track are all configured as dual tracks.

[0010] Furthermore, the transverse transfer track and the longitudinal transfer track are arranged to intersect perpendicularly.

[0011] Furthermore, the longitudinal transfer track and the casting track are arranged in parallel at intervals.

[0012] Furthermore, the longitudinal transfer track is set in two sets, which is arranged for the casting process of two production lines.

[0013] Furthermore, the length of the casting track is equal to the length of the single-anode casting production line and the dual-anode casting production line.

[0014] Furthermore, the first furnace front railcar, the second furnace front railcar, and the molten iron ladle installation area on the casting car are all set up as a single set, while the transfer car is equipped with two sets of molten iron ladle installation areas.

[0015] The beneficial effects of this invention compared to existing technologies are as follows: By continuously producing the required ferrophosphide aqueous solution using a medium-frequency furnace, and by installing multiple sets of furnace-front transfer cars at the medium-frequency furnace to transfer the produced ferrophosphide aqueous solution to a vertically arranged longitudinal transfer track, a secondary transfer is performed by the transfer cars on the longitudinal transfer track to the upper casting car on the casting track, ultimately completing the entire casting process. The arrangement of multiple tracks and transfer cars enhances the independence between each transfer track, improving the resilience of the transfer process. Flexibility and resource sharing: One medium-frequency furnace can flexibly serve two (or even more in the future) casting production lines, achieving the sharing of key resources (the medium-frequency furnace) and breaking the rigid binding between equipment. High production flexibility and reliability: When a casting station production line within the entire system undergoes planned maintenance or malfunctions, the system can still be adjusted according to on-site needs to ensure the normal production of another production line, thereby minimizing the impact of the malfunction and improving the reliability of the entire system.

[0020] See Figure 1The present invention discloses a novel ground casting track trolley production line system, comprising an intermediate frequency furnace 1, a casting controller 901, a single-anode casting production line 2, and a double-anode casting production line 3. The intermediate frequency furnace 1 has a transverse transfer track 10 on one side, and a first furnace front track 4 and a second furnace front track 40 are mounted on the upper side of the transverse transfer track 10. At least one set of longitudinal transfer tracks 8 are provided between the single-anode casting production line 2 and the double-anode casting production line 3 and the transverse transfer track 10, and at least one set of transfer cars 6 are mounted on the longitudinal transfer track 8. A casting track 30 is provided between the single-anode casting production line 2 and the double-anode casting production line 3 and the longitudinal transfer track 8, and a casting car 9 is mounted on the casting track 30. The positions of the first furnace front railcar 4, the second furnace front railcar 40, the transfer car 6, and the casting car 9 are transmitted wirelessly via a wireless signal receiver 5. The wireless signal receiver 5 integrates the signals and then transmits them to the casting controller 901. The transverse transfer track 10, the longitudinal transfer track 8, and the casting track 30 are all double-tracked, which increases their stability during transportation. The transverse transfer track 10 and the longitudinal transfer track 8 are arranged perpendicularly. The longitudinal transfer track 8 and the casting track 30 are arranged parallel and spaced apart. The casting process is the process of firmly combining the anode carbon block with the steel claw into one piece. This component is a core consumable in electrolytic aluminum production. The process mainly consists of three parts: the medium-frequency furnace, the casting car, and the casting station. The medium-frequency furnace operates on the principle of electromagnetic induction, converting the power frequency (50Hz) AC current into medium-frequency (300Hz to 2500Hz) AC current. This medium-frequency current passes through an induction coil wound with copper tubes, generating a high-intensity, rapidly changing alternating magnetic field inside the coil. When a crucible containing metal charge is placed in the center of a coil, the magnetic field generates a strong induced eddy current inside the metal, causing the metal to heat up until it melts. The casting trolley usually runs back and forth between the molten iron receiving station and the casting station along a track, and is equipped with a tiltable ladle of molten iron. Existing casting stations typically include a meshing station, a stepper or conveyor track, a guide rod clamping device, and the casting station itself.

[0021] Specifically, the length of the casting rail 30 is equal to the length of the single-anode casting line 2 and the double-anode casting line 3, thereby improving the casting effect during casting.

[0022] Specifically, the molten iron ladle installation areas on the first furnace front railcar 4), the second furnace front railcar 40, and the casting car 9 are all set up as a single set. The transfer car 6 is equipped with two sets of molten iron ladle installation areas. In use, one of the two molten iron ladle installation areas on the transfer car is responsible for receiving the molten iron ladles placed on the first furnace front railcar 4 and the second furnace front railcar 40 and sending them to the casting car. The other is responsible for recovering the empty molten iron ladles on the casting car and returning them to the furnace front railcar to re-collect the phosphorus iron solution.

[0023] The smelting unit includes an intermediate frequency furnace 1 and a first furnace front railcar 4 and a second furnace front railcar 40, responsible for smelting and initial transfer of ferrophosphate solution. The transfer hub's core equipment is an intelligent transfer car, whose longitudinal transfer track 8 intersects perpendicularly with the transverse transfer track 10. This transfer car has two ladle placement positions, responsible for receiving fully loaded ladles and sending them to transfer car 6 on the longitudinal transfer track, which then transports them to casting cars 9 near the single-anode casting line 2 and the double-anode casting line 3, respectively. Empty ladles are then retrieved and returned to the first furnace front railcar 4 and the second furnace front railcar 40 to re-collect ferrophosphate solution. The casting units are located in front of or to the sides of the intermediate frequency furnace, with each line including its own casting trolley and walking beam system. Two sets of longitudinal transfer tracks 8 are arranged perpendicularly to the transverse transfer tracks 10. A transfer car 6 and a second transfer car 60 with identical structures are installed on each of the two sets of longitudinal transfer tracks 8. This arrangement represents a novel casting process layout for two production lines. The workflow is as follows: The intermediate frequency furnace 1 pours ferrophosphate solution into the molten iron ladles of the first furnace front railcar 4 and the second furnace front railcar 40. Each of the two furnace front railcars runs on the transverse transfer track 10 until it is perpendicular to both the transverse and longitudinal transfer tracks, and moves the fully loaded molten iron ladle to the molten iron ladle at the placement positions of the transfer car 6 and the second transfer car 60. At this time, the transfer car rotates 90° in the direction of the molten iron ladle to ensure the opening of the fully loaded molten iron ladle is perpendicular to the casting production line. The two transfer cars then run on the casting tracks, which are parallel to the longitudinal transfer tracks, and the corresponding casting cars 9 and 90 are placed on the two sets of casting tracks. This allows the casting car 9 to supply material for the single-anode casting production line 2, and the second casting car 90 to supply material for the double-anode casting production line 3. The empty molten iron ladle is received by the transfer car 6 from the casting car 9. Then, the fully loaded molten iron ladle on the transfer car 6 is transported to the casting car 9. Finally, the casting car pours the ferrophosphate solution onto the anode carbon blocks and steel claws on the single anode casting line 2 and the double anode casting line 3 to complete the anode casting operation. At the same time, the transfer car rotates the empty molten iron ladle 90° and sends it to the first furnace front rail car 4 and the second furnace front rail car 40 to re-collect the ferrophosphate solution smelted in the medium frequency furnace. The cycle is repeated. In the whole system, the position control signal transmission and reception between the furnace front rail, the transfer car and the casting car are carried out wirelessly. The wireless signal receiver 5 integrates the signals and then transmits them to the casting controller.

[0024] In addition to the preferred embodiments described above, the present invention has other embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection claimed by the present invention.
