Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vacuum chambers, in particular to an argon small tube fixing device and a dipping tube steel structure. Background Art
[0002] The argon small tube of the vacuum chamber dipping tube is a device for providing argon gas installed on the vacuum chamber dipping tube. This device is a device for providing the power source for vacuum treatment - the driving gas. The driving gas serves as the driving force for the molten steel, and the flow rate thereof directly affects the molten steel circulation flow rate. If the provided argon gas flow rate is too small, it will lead to insufficient driving force, relatively weakened molten steel circulation power, relatively smaller molten steel lifting height, and smaller potential energy difference between the molten steel near the riser and the molten steel near the downcomer, resulting in weakened molten steel circulation and smaller molten steel circulation flow rate, directly affecting the metallurgical effects of vacuum treatment such as dehydrogenation, degassing, and alloy homogenization of the molten steel, leading to poor dehydrogenation of the molten steel, affecting the quality of the molten steel, resulting in steel modification and rejection, and even leading to safety accidents such as rail breakage. At the same time, the argon bubbles blow the ladle slag outwards to the wire, which will affect the personal safety of the post operators. Eventually, due to the leakage of the argon small tube in the vacuum chamber, the vacuum chamber abnormally goes offline.
[0003] Therefore, during the production process, the argon gas flow rate in the argon small tube must meet the design requirements. However, during actual use, the dipping tube equipped with the argon small tube needs to be lifted into the knotting device for corundum material pouring. During the pouring process, the worker stirs the corundum pouring material outside the dipping tube with a vibrating rod. This operation process will cause the argon small tube installed outside the dipping tube to displace. Some argon small tubes are exposed from the pouring material, and some argon small tubes are close to the outer pouring material. As the pouring material melts and wears during the production process, the argon small tube is exposed. During the RH hydraulic slag tapping operation, the displaced argon small tube may be damaged, resulting in air leakage of the argon small tube during the production process, thus making the safety during production unable to be guaranteed.
[0004] Therefore, how to prevent the displacement of the argon small tube and ensure the safety during production is a technical problem that needs to be solved by those skilled in the art at present. Summary of the Utility Model

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.
[0025] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by terms such as "upper", "lower", "top surface", "bottom surface", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the indicated positions or elements must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.
[0026] Such as Figure 1 And Figure 2As shown in the figure, the argon small tube fixing device disclosed by the utility model includes a clamping component, which is used to be arranged on the outer side of the dip tube steel structure 400 and form a plurality of fixing channels 200. The extending directions of the fixing channels 200 are parallel, and the fixing channels 200 are used to be clamped with the argon small tubes 100 to limit the argon small tubes 100. Specifically, the fixing channel 200 itself is a limiting member for the argon small tube 100, that is, the single argon small tube 100 is limited through the inside of the fixing channel 200, so as to prevent its displacement. When the argon small tube fixing device provided by the utility model is used, the clamping component is arranged on the outer side of the dip tube steel structure 400 to form a plurality of fixing channels 200, and a plurality of argon small tubes 100 are respectively arranged inside the plurality of fixing channels 200 to form a limit, thus avoiding the displacement of the argon small tubes 100 during the production process and ensuring the safety during production.
[0027] To optimize the above technical solution, the clamping component includes a plurality of baffles 300, the baffles 300 are arranged perpendicular to the dip tube steel structure 400, and a fixing channel 200 is formed between two adjacent baffles 300. Specifically, the fixing channel 200 formed between two adjacent baffles 300 can only limit the lateral displacement of the argon small tube 100 and cannot limit its displacement in the direction away from the dip tube steel structure 400. Therefore, during actual use, after the argon small tube 100 is arranged inside the fixing channel 200, the operator can hammer the baffle 300 in the direction close to the argon small tube 100, so that the baffle 300 is close to the argon small tube 100 to limit it and further prevent its displacement and avoid its air leakage, thus ensuring the safety during production.
[0028] In some embodiments, the baffle 300 is L-shaped, and its first end is fixedly connected to the dip tube steel structure 400, and the second end is used to limit the argon small tube 100. Specifically, when the baffle 300 is L-shaped, a fixing channel 200 is formed at the corner of the baffle 300, and two adjacent baffles 300 enclose a square fixing channel 200 to be used for accommodating and limiting the argon small tube 100, so that the step of hammering the baffle 300 can be omitted, which plays a role in protecting the argon small tube 100 and preventing its displacement. It should be noted that the above fixed connections are preferably welding.
[0029] In some embodiments, the clamping assembly includes a plurality of clamping members. The middle of the clamping member bulges to form a fixing channel 200. Connection portions are arranged at both ends of the clamping member, and the connection portions are fixedly connected to the impregnating tube steel structure 400. Specifically, the connection portion is sheet-shaped and is welded to the impregnating tube steel structure 400 to fix the middle bulge, that is, the fixing channel 200, to the impregnating tube steel structure 400. At the same time, a plurality of argon small tubes 100 are individually fixed. Even if one of the argon small tubes 100 is displaced, since the clamping member is an independent structure, it will not affect the other argon small tubes 100, thereby further avoiding the displacement of the argon small tubes 100 during the production process and ensuring the safety during production.
[0030] As Figure 3 shown, in some embodiments, the clamping assembly is of an integral design. The clamping assembly further includes a fixing plate 500, and the fixing plate 500 is arranged in contact with the outer side of the impregnating tube steel structure 400. The baffle 300 is perpendicular to the fixing plate 500 and is fixedly connected to the fixing plate 500. Specifically, the fixing plate 500 is welded to the outer side of the impregnating tube steel structure 400, and the baffle 300 is fixedly connected to the fixing plate 500, so that during the installation of the clamping assembly, only by welding the fixing plate 500, a plurality of fixing channels 200 can be formed at the same time, thereby simplifying the installation steps and improving the installation efficiency.
[0031] To optimize the above technical solution, the argon small tube fixing device further includes a sealing plate, and the sealing plate is fixedly connected to the clamping assembly, and the sealing plate is provided with a plurality of semi-holes for the argon small tubes 100 to pass through. During use, when the argon small tubes 100 pass through the fixing channel 200, the sealing plate covers the upper part of the plurality of argon small tubes 100, and the semi-holes hold at least half of the circumference of the argon small tubes 100, thereby further limiting the argon small tubes 100 and avoiding damage caused by the displacement of the argon small tubes 100, ensuring the safety during production.
[0032] To optimize the above technical solution, the argon small tube fixing device further includes a filling member, and the filling member is arranged inside the fixing channel 200 and is used to fill the gap between the fixing channel 200 and the argon small tubes 100. Specifically, the filling member can be a flexible filling member or a rigid filling member, as long as it can be filled between the fixing channel 200 and the argon small tubes 100 to further fix the argon small tubes 100, which will not be elaborated herein.
[0033] In summary, by providing a clamping assembly on the steel structure 400 of the dip tube and forming a plurality of fixing channels 200 for limiting or fixing the argon small tubes 100, the displacement of the argon small tubes 100 installed on the outer side 400 of the dip tube can be prevented, thereby avoiding damage to the argon small tubes 100, effectively preventing air leakage of the argon small tubes 100, preventing the occurrence of safety accidents such as rail breakage, and at the same time achieving and ensuring the personal safety of the on-site operators. Therefore, by forming the fixing channels 200, the safety of the equipment and personnel during production can be effectively guaranteed.
