Description

Technical Field

[0001] This utility model relates to the field of automatic fluidization technology for powdery materials in steel structure silos, and in particular to an anti-tilting device for installing a long water inlet on a large package. Background Technology

[0002] In the continuous casting industry, the pouring of molten steel and iron from the ladle to the tundish is generally sealed using a long nozzle on the ladle. This effectively isolates the molten steel from contact with the atmosphere, reduces secondary oxygen absorption by the high-temperature molten steel, and helps reduce the oxygen content and non-metallic inclusions in the steel, thereby improving the internal quality of the cast billet. In addition, the sealed pouring of molten steel reduces heat loss and stabilizes the temperature drop during the process.

[0003] During use, the long sprue nozzle of the large package is typically fixed to the front end by a hydraulic robotic arm. This, along with argon gas sealing and a sealing ring, creates a stable sealing environment. It is then fitted onto the sliding sprue nozzle at the bottom of the large package. Installation requires that it be kept vertical and not tilted. If tilted, the seal will be incomplete, allowing oxygen to be drawn in and causing secondary oxidation.

[0004] The commonly used installation method for long sprue nozzles on large bags involves placing a circular support ring at the front end of a hydraulic robotic arm. This ring can be a single, solid circle or composed of two detachable semicircles. Its purpose is to lift the long sprue nozzle for mounting the sliding sprue nozzle on the bottom of the bag. The most common problem with existing installation devices is that the long sprue nozzle tilts during mounting, requiring manual correction with hooks or other tools. This is time-consuming, labor-intensive, ineffective, and carries the risk of secondary oxidation. Utility Model Content

[0005] This utility model addresses the defects or deficiencies in the existing technology by providing an anti-tilting device for installing long sprue nozzles on large packages. It replaces the existing circular support ring, which helps to ensure the verticality of the long sprue nozzle installation and prevents tilting problems.

[0006] The technical solution of this utility model is as follows:

[0007] A device for preventing tilting of a long sprue nozzle on a large package, characterized in that it includes a first sprue nozzle fixing ring that holds the long sprue nozzle in a hugging manner, and a second sprue nozzle fixing ring surrounding the first sprue nozzle fixing ring. Both the first and second sprue nozzle fixing rings have front openings, the rim of which covers the large head of the long sprue nozzle. The left and right sides of the first sprue nozzle fixing ring are straight lines, and the rear side of the first sprue nozzle fixing ring is a semi-circular arc extending rearward from the straight lines. The upper section of the first sprue nozzle fixing ring is adapted to the circumference of the large head, and the middle section of the first sprue nozzle fixing ring... The lower section of the first nozzle fixing ring is adapted to the circumferential surface of the long neck of the large nozzle, which is compatible with the transition and contraction section of the large nozzle. The second nozzle fixing ring is square. The upper half of the second nozzle fixing ring is provided with a left-side adjusting screw, a right-side adjusting screw, and a rear-side adjusting screw of the large head passing through the first nozzle fixing ring. The lower half of the second nozzle fixing ring is provided with a left-side adjusting screw, a right-side adjusting screw, and a rear-side adjusting screw of the neck root passing through the first nozzle fixing ring. The rear side of the second nozzle fixing ring has a rearwardly extending connecting handle.
