[0002] Twin-roller thin strip continuous casting technology is a cutting-edge technology in the modern metallurgical industry. This technology can directly cast and roll high-temperature molten metal into thin strip steel plates. The casting and rolling thickness can reach the range of 0.1mm-10mm, greatly shortening the production process of hot-rolled strip steel. It is currently the hot-rolled strip production technology with the shortest process. The thin strip continuous casting process is a sub-rapid solidification process of metals, which can become an important solution to the most difficult plasticity, segregation, inclusions, uniformity, energy consumption and other problems in the processing of high-alloy materials.

[0003] The prior art can refer to the Chinese patent with the authorization publication number CN211803726U, which discloses a double-roller ultra-thin strip continuous casting pouring cloth water outlet, including a side wall and an end face, the side wall and the end face enclose a cavity, the bottom of the side wall is provided with a plurality of steel tapping holes, the outer bottom of the side wall is provided with a steady flow groove at a position flush with the steel tapping hole, and the steady flow groove is connected to the steel tapping hole, but the cloth water outlet still has shortcomings during use:

[0004] First, during the discharge of molten steel, the molten steel in the molten pool fluctuates due to the flow, which can easily cause gaps or unevenness on the steel plate extruded by the casting roll, affecting the quality of the steel plate;

[0005] Secondly, the adjustability is poor and it cannot be applied to casting rolls with different spacings. It also makes it impossible to adjust the height of the water outlet from the molten pool, which easily causes molten steel to splash during water distribution and has poor safety.

[0006] Therefore, a double-roller ultra-thin strip continuous casting pouring cloth water outlet structure is provided. Utility Model Content

[0007] In view of the deficiencies in the prior art, the utility model provides a double-roller ultra-thin strip continuous casting pouring cloth water outlet structure, which effectively reduces the fluctuation of molten steel in the molten pool through the coordinated use of the arranged U-shaped seat, the guide pipe, the drainage hole and the distribution flow assembly, avoids the appearance of gaps or unevenness on the steel plate extruded by the casting and rolling rollers, thereby ensuring the production quality of the steel plate, and can adapt to the use of casting and rolling rollers with different spacings through the arranged lifting frame and the adjustment limit assembly, and can avoid the splashing of molten steel during casting and rolling, thereby ensuring safety, overcoming the deficiencies in the prior art, and effectively solving the problem that when the existing double-roller ultra-thin strip continuous casting pouring cloth water outlet is used, the molten steel in the molten pool fluctuates due to the flow during the molten steel discharge process, which easily causes gaps or unevenness on the steel plate extruded by the casting and rolling rollers, affecting the quality of the steel plate and having poor adjustability, and cannot be applied to casting and rolling rollers with different spacings, and the height of the distribution flow outlet from the molten pool cannot be adjusted, which easily causes the molten steel to splash during the distribution flow and has poor safety.
