Description

Technical Field

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

[0002] In 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 currently 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 production of steel billets required for the production of traditional steel billet standard parts is all carried out 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-steel billet standard parts, the steel billets required will be 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, the worker will operate the pressure handle in the guide mechanism on the tundish to open and close the stopper rod. When the stopper rod is opened, the flow rate of molten steel increases, and when the stopper rod is closed, the flow rate of molten steel slows down or even stops. By opening and closing the stopper rod to control the outflow rate of molten steel, the worker can control the liquid level in the crystallizer to keep the liquid level at the same height, and keep the liquid level stable during the control process, or change the liquid level according to other process requirements. This kind of steel billet often has high precision requirements, and this kind of operation requires a high level of proficiency of the operator. Generally, it is operated by experienced workers, and new steel pouring workers cannot directly perform this job due to lack of actual production experience. Therefore, whether it is automated steel pouring or manual steel pouring, new steel pouring workers lack training opportunities and environment, which brings great inconvenience to the production of new operators.

[0006] If new operators perform relevant operations without experience, due to their inexperience, they cannot ensure the stability of the liquid level of the molten steel in the crystallizer when pouring steel, which leads to frequent quality problems such as cracks and defects in the cast steel billets, and the production efficiency of casting steel billets is 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 ingots will also be guaranteed, reducing the probability of quality problems with the steel billets.

[0031] The present invention will be further described in detail below in conjunction with specific examples. The following examples are only illustrative and not restrictive, and the protection scope of the present invention cannot be limited thereto.

[0032] The raw materials used in the present invention, unless otherwise specified, are conventional commercial products, the methods used in the present invention, unless otherwise specified, are conventional methods in the art, and the quality of each substance used in the present invention is conventional quality. The structures, connection relationships, etc. not described in detail in the present invention can be understood as conventional technical means in the art.

[0033] A continuous casting start pouring and manual pouring simulation trainer, such as Figure 1 , Figure 2As shown, the trainer includes a simulated middle package container 1, a guide mechanism 2, a flow 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 package container and the simulated crystallizer are arranged in a vertical direction. The top of the simulated middle package container is coaxially provided with a top inlet 11, the bottom of the simulated middle package 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 package container is tightly connected with the top inlet of the simulated crystallizer through the flow guide pipe, and the bottom outlet of the simulated crystallizer is tightly connected with the top inlet of the simulated middle package 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 package container through the second simulated pipeline, so that the simulated casting liquid can be reused, which reduces the production cost and brings convenience to the enterprise;

[0034] The guide mechanism is connected to the simulated middle package container, which includes a stopper rod 26. The stopper rod is arranged in the vertical direction and the lower part thereof is coaxially arranged in the simulated middle package container. The bottom of the stopper rod can be coaxially movably and tightly connected with the bottom outlet of the simulated middle package, so that the stopper rod can be closely contacted with the bottom outlet of the simulated middle package when moving downward, thereby preventing 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 middle package.

[0035] When the trainer of the present invention is operated, the pressure handle of the guide mechanism is pressed, and the guide mechanism transmits the force of the staff to the stopper rod, so that the stopper rod opens and closes the bottom outlet of the simulated container, and then the simulated casting liquid flows out of the container and enters the guide pipe, and the simulated casting liquid flows into the simulated crystallizer through the guide pipe. The staff continuously adjusts the opening and closing of the stopper rod by pressing and lifting the pressure handle, so that the simulated casting liquid level inside the simulated crystallizer remains stable. This link can simulate the situation of the casting liquid in the actual casting crystallization process, and then the simulated casting liquid flows from the bottom outlet of the simulated crystallizer into the first simulation pipeline, and the simulated casting liquid flows into the booster pump through the first simulation pipeline, and then into the second simulation pipeline through the booster pump, and finally the simulated casting liquid flows back into the simulated container through the second simulation pipeline, and the simulation training is carried out in turn in a cycle, saving energy. At the same time, the trainer of the present invention can simulate the relevant operating procedures of continuous casting production, provide sufficient training opportunities for new steel workers, reduce the production cost of the enterprise, and bring great convenience to the production of the enterprise.

[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 casting liquid in the actual casting process, improve the simulation degree 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 casting start and stop straightening, improve the liquid transportation efficiency and simulation degree. 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 of the crystallizer is completed in the actual production process, and improve the liquid transportation efficiency and simulation degree.

[0037] In this embodiment, the simulated tundish container is hollow inside, and the top and bottom centers are coaxially provided with a top inlet and a bottom outlet in a sealed shape. The diameter of the top inlet is larger than the diameter of the through hole at the bottom, so as to ensure that the feed amount is larger than the discharge amount and the normal progress of the process. The hollow inside 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, 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, 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 in a sealed shape. 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 shape.

[0040] The guide mechanism of the trainer of the present invention can convert the rotational power of the pressure handle into vertical power and transmit it to the transmission rod through the crank slider mechanism. 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 intermediate package container.

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

[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 set, 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 in 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 middle bag operation panel. By adjusting the flow rate, controlling the flow rate and starting and stopping the booster pump, the actual middle bag operation panel and operation process are simulated.

[0047] In this embodiment, the simulated casting liquid is a non-corrosive liquid medium with a certain viscosity, so that it can simulate the actual casting 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 appreciate that various substitutions, 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.
