Description

Technical Field

[0001] The utility model belongs to the technical field of steelmaking equipment, in particular to a continuous casting start-up and manual pouring simulation trainer. Background Art

[0002] During the continuous casting process, molten steel generally passes through the tundish and then flows into the crystallizer for solidification. In this production work, since different steel billets have different production needs and quality requirements, the molten steel needs a stable liquid level in the crystallizer to ensure the quality and category of the produced steel billets. Therefore, the opening and closing of the stopper rod plays a vital role in the production of steel billets.

[0003] As steel mills have increasingly stringent requirements for the quality of ingots, most steel mills now use automatic continuous casting equipment to make standard parts. At the same time, due to the increasingly stringent requirements for the quality of ingots and the use of automated equipment, new steel casting workers often do not have the opportunity and environment for training.

[0004] At present, the traditional production of steel billet standard parts is all produced by automatic casting using automated equipment. This automated casting production greatly reduces the opportunities for new steel casters to participate in production practice and training opportunities. For the production of non-standard steel billet parts, the steel billets are manually designed and cast according to the needs of different manufacturers.

[0005] In daily steelmaking production, after the crane has finished pouring molten steel into the tundish, workers will operate the pressure handle in the guide mechanism on the tundish to open and close the stopper. When the stopper is opened, the molten steel flow rate increases, and when the stopper is closed, the molten steel flow rate slows down or even stops. By opening and closing the stopper, the molten steel flow rate is controlled, allowing workers to control the liquid level in the crystallizer, keeping it at a constant height. During the control process, the liquid level remains stable, or changes according to other process requirements. This type of steel billet often requires high precision, and this operation requires a high level of proficiency from the operator. Generally, it is performed by experienced workers. New steel pourers are unable to directly perform this job due to their lack of actual production experience. Therefore, whether it is automated or manual steel pouring, new steel pourers lack the opportunity and environment for training, which brings great inconvenience to new operators.

[0006] If a new operator performs relevant operations without experience, the new steel casting worker cannot ensure the stability of the liquid level of the molten steel in the crystallizer when casting steel, which will lead to frequent quality problems such as cracks and defects in the cast steel billets, and the production efficiency of casting steel billets will be greatly reduced.

[0007] Therefore, there is an urgent need to produce an offline operation simulation trainer. Under the guidance of a master and after offline training, manual pouring can be performed in the production process for actual operation, and the cast billets will also be guaranteed, reducing the probability of quality problems in the billets.

[0031] The present invention will be further described in detail below in conjunction with specific embodiments. The following embodiments are merely illustrative and non-restrictive, and should not be used to limit the scope of protection of the present invention.

[0032] Unless otherwise specified, the raw materials used in this utility model are all conventional commercial products.

The quality of each substance used in this utility model is the quality of conventional use. The structures, connections, etc. not described in detail in this utility model are to be understood as conventional technical means in the field.

[0033] A continuous casting and manual pouring simulation trainer, such as Figure 1 、 Figure 2As shown, the trainer includes a simulated middle container 1, a guide mechanism 2, a guide pipe 3, a simulated crystallizer 4, a first simulated pipeline 5, a booster pump 6, a second simulated pipeline 7 and a simulated casting liquid 8. The simulated middle container and the simulated crystallizer are both arranged in a vertical direction. The top of the simulated middle container is coaxially provided with a top inlet 11, the bottom of the simulated middle container is coaxially provided with a bottom outlet 12, the top of the simulated crystallizer is coaxially provided with a top inlet 41, the bottom of the simulated crystallizer is coaxially provided with a bottom outlet 42, the bottom outlet of the simulated middle container is tightly connected to the top inlet of the simulated crystallizer through the guide pipe, and the bottom outlet of the simulated crystallizer is tightly connected to the top inlet of the simulated middle container through the first simulated pipeline, the booster pump and the second simulated pipeline, so that the simulated casting liquid flows into the simulated middle container through the second simulated pipeline, thereby making the simulated casting liquid reusable, reducing production costs and bringing convenience to enterprises;

[0034] The guide mechanism is connected to the simulated tundish container, which includes a stopper rod 26. The stopper rod is arranged in a vertical direction and the lower part thereof is coaxially arranged in the simulated tundish container. The bottom of the stopper rod can be coaxially movably and tightly connected with the bottom outlet of the simulated tundish, so that when the stopper rod moves downward, it can be closely contacted with the bottom outlet of the simulated tundish to prevent the simulated casting liquid from overflowing when it is not needed to flow out; the guide mechanism can be connected to the top of the stopper rod, and the guide mechanism can drive the stopper rod to move up and down in the vertical direction, thereby opening and blocking the bottom outlet of the simulated tundish.

[0035] During operation, the present invention trainer is operated by pressing the handle of the guide mechanism. The guide mechanism transmits the operator's force to the stopper rod, causing the stopper rod to open and close the bottom outlet of the simulated container. The simulated casting liquid then flows out of the container and into the guide pipe. The simulated casting liquid flows into the simulated crystallizer through the guide pipe. The operator continuously adjusts the opening and closing of the stopper rod by pressing and lifting the handle to keep the simulated casting liquid level inside the simulated crystallizer stable. This process can simulate the casting liquid in the actual casting crystallization process. The simulated casting liquid then flows from the bottom outlet of the simulated crystallizer into the first simulated pipe, flows through the first simulated pipe into the booster pump, and then is pumped into the second simulated pipe by the booster pump. Finally, the simulated casting liquid flows back into the simulated container through the second simulated pipe. The simulated training is repeated in this cycle, saving energy. At the same time, the present invention trainer can simulate the relevant operating procedures of continuous casting production, providing sufficient training opportunities for new steel workers, reducing the production costs of enterprises, and bringing great convenience to the enterprise's production.

[0036] The present invention adopts a simple mechanical mechanism and a hydraulic mechanism, so that the guide mechanism can amplify the force of the staff and transmit it to the stopper rod, so that it can open and close the simulated intermediate ladle container, reducing the staff's energy consumption and improving work efficiency. The setting and use of the guide tube enables the present invention to better simulate the flow process of the pouring liquid in the actual pouring process, improve the simulation level of the present invention, and improve accuracy and stability. The setting and use of the booster pump enables the present invention to improve the start and stop of the booster pump to simulate the actual pouring start and stop straightening, thereby improving the liquid transportation efficiency and the simulation level. The use of the first simulation pipeline and the second simulation pipeline enables the present invention to simulate the process of the crystallizer flowing out of the crystallizer after the crystallizer process is completed in the actual production process, thereby improving the liquid transportation efficiency and the simulation level.

[0037] In this embodiment, the simulated tundish container is hollow inside, with a top inlet and a bottom outlet coaxially arranged at the top and bottom centers in a sealed shape. The diameter of the top inlet is larger than the diameter of the through hole at the bottom, ensuring that the feed rate is greater than the discharge rate, ensuring the normal progress of the process. The hollow interior of the simulated tundish container can hold simulated pouring liquid, so that it can simulate the tundish container and related work in the actual molten steel pouring process;

[0038] The guide mechanism further includes a pressure handle 21, a crank slider mechanism 22, a transmission rod 23, a hydraulic transmission mechanism 24 and a stopper rod clamp 25. The pressure handle and the stopper rod clamp are both arranged in the horizontal direction. The horizontal end of the pressure handle is connected to the rotation input end of the crank slider mechanism, and the vertical output end of the crank slider mechanism is connected to the vertical end of the transmission rod. The transmission rod is arranged in the vertical direction, and the other vertical end of the transmission rod is connected to the input end of the hydraulic transmission mechanism. The output end of the hydraulic transmission mechanism is connected to the stopper rod clamp, and the stopper rod clamp is connected to the top of the stopper rod.

[0039] The simulated crystallizer is hollow inside, and has a top inlet and a bottom outlet coaxially arranged at the top and bottom centers, and is sealed. The diameter of the top inlet is larger than the diameter of the through hole at the bottom, so that it can simulate the actual process of pouring molten steel into the crystallizer and flowing out of the crystallizer in a shaped manner.

[0040] The guide mechanism of the trainer of the present invention can convert the rotational power of the pressure handle into vertical power through the crank slider mechanism and transmit it to the transmission rod. The transmission rod can amplify the vertical power through the hydraulic transmission mechanism and transmit it to the clamp. The clamp can operate the opening and closing of the bottom of the container by moving the stopper rod up and down. Such a guide mechanism can reduce the power consumed by the staff when opening and closing the stopper rod, so that it can simulate the opening and closing operation of the actual guide mechanism in the tundish container.

[0041] In this embodiment, the first simulation pipeline is detachably connected to the simulated crystallizer and the booster pump, so that the simulated casting liquid flows from the simulated crystallizer to the booster pump through the first simulation pipeline;

[0042] The booster pump is detachably connected to the second pipeline, so that the simulated pouring liquid flow is pumped into the second simulation pipeline through the booster pump. By operating the start and stop of the booster pump, the start and stop of actual pouring can be simulated, thereby improving the liquid transportation efficiency and the degree of simulation.

[0043] In this embodiment, the guide tube can be detachably and tightly connected to the simulated middle container and the simulated crystallizer, so that it can simulate the effect that the water outlet of the container and the water inlet of the crystallizer are connected in practice.

[0044] In this embodiment, the simulated crystallizer is a copper tube. The bottom opening of the copper tube is sealed and a circular hole is provided. The diameter of the circular hole is smaller than the diameter of the copper tube, so that the copper tube can simulate the process of pouring molten steel into the crystallizer and flowing out of the crystallizer into shape. It is simple to operate and easy to make, which brings great convenience to production.

[0045] In this embodiment, the guide mechanism is equipped with a reducer, the output end of the reducer is connected to the input end of the crank slider mechanism, and the input end of the reducer is connected to the pressure handle, so as to increase the torque of the pressure handle.

[0046] In this embodiment, the booster pump is an adjustable booster pump, which can control the flow rate and simulate the mid-package operation panel. By adjusting the flow rate, controlling the flow rate and starting and stopping the booster pump, the actual mid-package operation panel and operation process are simulated.

[0047] In this embodiment, the simulated pouring liquid is a non-corrosive liquid medium with a certain viscosity, so that it can simulate the actual pouring of molten steel.

[0048] Preferably, the simulated pouring liquid is flame-retardant heavy oil, so that it can better simulate the actual pouring of molten steel.

[0049] Although the embodiments of the present invention are disclosed for illustrative purposes, those skilled in the art will understand that various replacements, changes and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments.
