Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy hot-top casting technology, specifically a high-performance aluminum alloy hot-top casting platform with protective functions. Background Technology

[0002] High-performance aluminum alloys, with their high strength, low density, excellent corrosion resistance, and machinability, have become core materials in aerospace, new energy vehicles, and high-end equipment manufacturing. Hot-top casting, a key process in the production of high-performance aluminum alloy ingots, reduces solidification shrinkage defects at the ingot head by installing a heat-insulating device at the top of the crystallizer, thereby increasing the ingot yield to over 90%. It also enables the production of high-quality ingots with large diameters and long lengths, meeting the processing needs of large components.

[0003] The prior art discloses a high-performance aluminum alloy hot-top casting platform with protective function, with announcement number CN216226849U. The platform includes a base and a support frame. The support frame is fixedly connected to the top of the base. A top sealing cover is provided on the inner side of the support frame. Electro-hydraulic columns are fixedly connected to both sides of the top of the top of the top sealing cover. The top ends of the two electro-hydraulic columns are fixedly connected to the bottom of the inner wall of the support frame. A hot-top casting mold is fixedly connected to the bottom of the top sealing cover. After the top sealing cover moves down and aligns with the protective bottom box, the sealing flange can be inserted into the slot, thereby improving the sealing performance between the top sealing cover and the bottom protective box and preventing water vapor leakage. Water vapor generated during water cooling enters the interior of the box through a connecting pipe. Coolant flows through a threaded pipe, causing the water vapor inside the box to condense directly into liquid water, which then flows out through an outlet pipe.

[0004] The aforementioned high-performance aluminum alloy hot-top casting platform with protective functions can prevent water vapor from affecting worker operations and avoid accidental injury to workers and equipment. However, when entering the molten metal, the platform cannot automatically separate oxide inclusions and prevent filter clogging, making it easy for impurities to enter. As a result, its performance is not good and needs to be improved. Utility Model Content
