[0002] The integral stopper rod is a key material for controlling the casting flow of molten steel in the continuous casting process, and plays a crucial and irreplaceable role in ensuring the continuous casting production process.

[0003] The argon-blowing stopper rod is also a type of integral stopper rod. When in use, the operator can disperse inert gases such as argon into the molten steel in the container through the argon-blowing stopper rod, so as to form small and uniform bubbles in the molten steel, thereby effectively stirring and purifying the molten steel. For special steel grades, the common argon-blowing stopper rod has insufficient anti-blocking ability, and inclusions are easily adsorbed on the rod head during use, resulting in the blockage of the casting channel and the inability to continue the continuous casting process.

[0004] Therefore, the utility model provides a porous argon-blowing anti-blocking rod head to solve the above problems. Content of the Utility Model

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figure 1 - Figure 2 , the present utility model provides the following technical solutions: A porous argon-blowing anti-clogging rod head, including a rod head 1, the top surface of the rod head 1 is connected with a body 2, the rod head 1 and the body 2 are integrally formed and combined together by isostatic pressing technology, a through first ventilation hole 3 is provided in the inner cavity of the body 2, a diffusion breathable plug 4 is provided in the inner cavity at the top end of the rod head 1, the other end of the diffusion breathable plug 4 extends into the interior of the body 2, a second ventilation hole 5 is provided on the bottom surface of the rod head 1, and a third ventilation hole 6 is provided on the outer surface at the bottom end of the rod head 1.

[0019] The first vent hole 3 is an intake channel for externally connected argon. Between the first vent hole 3, the second vent hole 5, and the third vent hole 6, the diffusion permeable plug 4 is used as a separator. The second vent hole 5 and the third vent hole 6 are outlet holes. The distribution quantity and distribution position of the third vent hole 6 need to be customized according to the blocked position of the rod head 1 and the measurement of the water model test.

[0020] Preferably: The position of the first vent hole 3 is communicated with the position of the diffusion permeable plug 4, and the position of the second vent hole 5 is also communicated with the position of the diffusion permeable plug 4.

[0021] During specific use, the argon transported inside the first vent hole 3 can be transported to the diffusion permeable plug 4, and then the diffusion permeable plug 4 diffuses the transported argon, allowing the diffused argon to enter the second vent hole 5, so that the diffused argon can be discharged outward through the second vent hole 5. The diffusion permeable plug 4 can not only ensure the smooth passage of argon but also ensure the pressure difference before and after the argon enters and exits.

[0022] Preferably: The position of the third vent hole 6 is communicated with the position of the second vent hole 5.

[0023] During specific use, the argon diffused inside the second vent hole 5 can also be discharged outward through the third vent hole 6. In this way, the second vent hole 5 and the third vent hole 6 are connected, and the internal pressure can be ensured to be consistent to ensure the uniformity of the argon blown out from the second vent hole 5 and the third vent hole 6.

[0024] Preferably: The aperture size of the second vent hole 5 is 5 ± 1 mm, the aperture size of the third vent hole 6 is 1 - 2 mm, and the third vent hole 6 is distributed in an annular array on the outer surface at the bottom end of the rod head 1.

[0025] During specific use, the distribution quantity and distribution position of the third vent hole 6 are customized according to the blocked position of the rod head 1 and the measurement of the water model test, so that the third vent hole 6 is distributed in an annular array on the rod head 1. The aperture size range of the second vent hole 5 is 5 ± 1 mm, and the aperture size range of the third vent hole 6 is 1 - 2 mm.

[0026] Working principle: When using this porous argon-blowing anti-clogging rod head, when the stopper rod is in use, the argon gas transported externally will be conveyed to the dispersion breathable plug 4 through the first ventilation hole 3 opened inside the body 2. When the transported argon gas passes through the dispersion breathable plug 4, according to the dispersion characteristics of the dispersion breathable plug 4, the passing argon gas will be dispersed. In this way, the argon gas that is dispersed and enters the second ventilation hole 5 will be evenly blown out from the second ventilation hole 5 and the third ventilation hole 6, so that the argon gas can be blown out from multiple positions of the rod head 1, thereby forming uniform argon bubbles and disturbing the molten steel. In this way, a three-dimensional multi-faceted wrapping effect will be formed at the position of the rod head 1 during the transportation of the argon gas, which can realize the transportation of a small argon gas flow rate, reduce the adsorption of inclusions, and achieve a better anti-clogging effect.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
