Description

Technical Field

[0001] This utility model relates to the field of demolding assistance technology, and in particular to a demolding assistance device for electroslag steel ingots. Background Technology

[0002] Demolding of electroslag remelted steel ingots is a crucial step in steel production, directly impacting the quality of subsequent processing and the final product. Currently, the application of release agents in this process has become a common technique in the industry. However, traditional methods of applying release agents typically rely on manual application or fixed spray systems. This is not only time-consuming and labor-intensive but also results in poor spray uniformity, leading to unstable demolding results and a tendency for steel ingots to stick to the mold, thus affecting production efficiency and product quality.

[0003] Therefore, we propose an auxiliary device for demolding electroslag steel ingots to solve the existing problems. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing an auxiliary device for demolding electroslag steel ingots.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary device for demolding electroslag steel ingots, comprising a tank and a gas chamber, wherein the top opening of the tank is provided with a cap, the cap is provided with a spray structure, the spray structure is composed of a nozzle, a suction chamber, a mixing pipe and a diffusion chamber, a suction pipe is provided through the cap, one end of the suction pipe is connected to the suction chamber of the spray structure, and the other end of the suction pipe is provided with a filter assembly;

[0006] The air chamber is located at the air inlet of the nozzle of the spray structure. The air chamber is equipped with an air control component, which is used to control the on / off state of the airflow entering the nozzle.

[0007] Preferably, the gas control assembly consists of a partition, a pressing plate, a movable port, a central port, and a spring. The partition is located in the middle of the interior of the gas chamber, and the central port is located at the center of the partition.

[0008] Preferably, the pressing plate passes through the air chamber and is slidably inserted into the partition, and the movable opening is opened on the pressing plate.

[0009] Preferably, the top end of the spring is located at the bottom end of the pressing plate, the bottom end of the spring is located at the bottom end of the inner wall of the partition, and the original length of the spring is greater than half the height of the partition.

[0010] Preferably, one side of the air chamber has an air inlet, and the other side of the air chamber has an air outlet, and the air outlet of the air chamber is connected to the air inlet of the nozzle.

[0011] Preferably, the filter assembly consists of a ring shell and a filter screen, the ring shell being threaded at the bottom end of the suction pipe, and the filter screen being disposed inside the ring shell.

[0012] Preferably, the outer wall of the cap is provided with paddles, and the paddles are arranged in a circular array on the cap.

[0013] Preferably, the outer wall of the tank is provided with a handle, and the middle section of the handle is glued with a rubber anti-slip sleeve.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This utility model of an electroslag steel ingot demolding auxiliary device can introduce the demolding agent for electroslag steel ingot demolding into the tank, then screw on the cap for temporary storage, and then connect to an external compressed air source through the gas control component.

[0016] When a release agent is needed, personnel control compressed air to enter the spray structure through the air control component. When the air is ejected at high speed from the nozzle, it continuously carries away the air in the suction chamber, creating a vacuum of varying degrees in the suction chamber. Under the action of negative pressure, the release agent inside the tank enters the suction chamber through the suction pipe. The release agent and the airflow mix in the mixing pipe to form a high-speed mixed flow. Then, the mixed flow is depressurized and sprayed onto the surface of the electroslag steel ingot mold through the diffusion chamber, thereby assisting the subsequent demolding operation.

[0017] In the above process, when the air control component is in use, it is connected to an external compressed air source through the air inlet of the air chamber. When the person presses down the press plate, the press plate moves down inside the partition. At this time, the spring is compressed and deformed. When the movable port of the press plate matches and connects with the center port of the partition, the compressed air enters the nozzle through the movable port and the center port.

[0018] When the air control component is not in use, the press plate is released and reset by the spring force. The moving port and the center port are misaligned, which disconnects the air passage and stops the nozzle from spraying out the release agent.

[0019] This invention utilizes a compressed air-driven spray structure to fully mix the release agent with the compressed air, forming a high-speed mixed flow. This ensures that the release agent is evenly distributed on the mold surface. Through the control of the air control component, the user can precisely control the flow rate of the compressed air according to actual needs, thereby precisely controlling the amount of release agent sprayed.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] like Figures 1-4 As shown, the present invention proposes an auxiliary device for demolding electroslag steel ingots, including a tank body 1 and a gas chamber 9. The top opening of the tank body 1 is provided with a cap 3, and the cap 3 is provided with a spray structure. The spray structure consists of a nozzle 5, a suction chamber 6, a mixing pipe 7 and a diffusion chamber 8. A suction pipe 10 is provided through the cap 3. One end of the suction pipe 10 is connected to the suction chamber 6 of the spray structure, and the other end of the suction pipe 10 is provided with a filter assembly.

[0029] The air chamber 9 is located at the air inlet of the nozzle 5 of the spray structure. The air chamber 9 is equipped with an air control component, which is used to control the on / off state of the airflow entering the nozzle 5. One side of the air chamber 9 has an air inlet, and the other side of the air chamber 9 has an air outlet. The air outlet of the air chamber 9 is connected to the air inlet of the nozzle 5.

[0030] The release agent for electroslag steel ingots can be introduced into the tank 1, and then the cap 3 can be screwed on for temporary storage. Then, the external compressed air source can be connected through the gas control component.

[0031] When a release agent is needed, personnel control compressed air to enter the spray structure through the air control component. When the air is ejected at high speed from the nozzle 5, it continuously carries away the air in the suction chamber 6, creating a vacuum of varying degrees in the suction chamber 6. Under the action of negative pressure, the release agent inside the tank 1 enters the suction chamber 6 through the suction pipe 10. The release agent and the airflow mix in the mixing pipe 7 to form a high-speed mixed flow. Then, the mixed flow passes through the diffusion chamber 8, where it is depressurized and sprayed onto the surface of the electroslag steel ingot mold, thereby assisting in the subsequent demolding operation.

[0032] Example 2

[0033] like Figures 1-4 As shown, the electroslag steel ingot demolding auxiliary device proposed in this utility model, compared with the first embodiment, further includes: a gas control component consisting of a partition 13, a pressing plate 14, a movable port 15, a central port 16 and a spring 17. The partition 13 is located in the middle of the air chamber 9, and the central port 16 is located at the center of the partition 13. The pressing plate 14 passes through the air chamber 9 and is slidably inserted into the partition 13. The movable port 15 is located on the pressing plate 14. When the gas control component is in use, it is connected to an external compressed air source through the air inlet of the air chamber 9. When the personnel press down the pressing plate 14, the pressing plate 14 moves downward in the partition 13. At this time, the spring 17 is compressed and deformed. When the movable port 15 of the pressing plate 14 matches and connects with the central port 16 of the partition 13, the compressed control air enters the nozzle 5 through the movable port 15 and the central port 16.

[0034] When the air control component is not in use, the press plate 14 is released. Under the elastic force of the spring 17, the press plate 14 moves upward to reset. The movable port 15 and the center port 16 are misaligned, causing the air passage to be disconnected. As a result, the nozzle 5 cannot enter air and stops the spraying of the release agent.

[0035] The top end of the spring 17 is located at the bottom end of the pressing plate 14, and the bottom end of the spring 17 is located at the bottom end of the inner wall of the partition 13. The original length of the spring 17 is greater than half the height of the partition 13. Through the design of the length of the spring 17, it is ensured that the spring 17 has sufficient elasticity to reset the pressing plate 14.

[0036] The filter assembly consists of a ring shell 11 and a filter screen 12. The ring shell 11 is threaded at the bottom end of the suction pipe 10, and the filter screen 12 is located inside the ring shell 11. Through the design of the filter assembly, the solid particles of the release agent entering the suction pipe 10 can be filtered.

[0037] The outer wall of the cap 3 is provided with a lever 4. The levers 4 are arranged in a circular array on the cap 3. The design of the levers 4 makes it convenient for people to apply a rotational force to the cap 3.

[0038] The outer wall of the tank 1 is provided with a handle 2, and the middle section of the handle 2 is glued with a rubber anti-slip sleeve. The design of the handle 2 makes it convenient for personnel to operate the tank 1.

[0039] The above specific embodiments are merely several preferred embodiments of this utility model.
