Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to the steel smelting equipment technical field, especially relates to a novel dummy bar hook head of ladle pouring leading casting blank. BACKGROUND
[0002] The dummy bar hook head is mainly applied to the continuous casting production field of the steel industry. Specifically, it is applied in different types of continuous casting production lines such as slab continuous casting, bloom continuous casting and round billet continuous casting. Its role is to pull out the initially solidified steel blank from the crystallizer at the beginning of continuous casting, and guide the steel blank to run along a specific track until normal casting. The dummy bar hook head is connected with the dummy bar head when the continuous casting machine starts pouring. The dummy bar hook head is made of 25mm threaded steel, and the threaded steel has weak tensile strength. During pouring, the threaded steel is easily pulled off, causing pouring pulling-off accidents. Handling the accident wastes a lot of time and affects production. When the hook head is made, in order to process the butt weld, some hook head welding points are too large to be installed in the dummy bar rod. Then, other hook heads are searched for installation, which wastes time again. The unuseable hook heads are discarded passively, causing a lot of waste. Searching for other hook heads to install wastes time again, increases operation time and enhances labor intensity. When plugging the dummy bar, 100 cold charges are used, and the second cold charge is added manually in two times. Due to the structure of the dummy bar hook head, some cold charges are stuck in the crystallizer horizontally, which does not meet the cold charge requirements for pouring. SUMMARY
[0003] The utility model discloses a novel dummy bar hook head of ladle pouring leading casting blank, which solves the problems in the prior art.
[0004] The utility model discloses a novel dummy bar hook head of ladle pouring leading casting blank, which solves the problems in the prior art.
[0005] A novel dummy bar hook head of ladle pouring leading casting blank, comprising a connecting rod, a connecting column is welded at the top end of the connecting rod, a casting blank connecting head is integrally formed at the bottom end of the connecting rod, a plurality of through holes are formed in the casting blank connecting head, and a dummy bar cap is penetrated through and welded on the connecting rod between the connecting column and the casting blank connecting head.
[0006] Further, the connecting column is transversely welded at one end of the connecting rod, and the welding position of the connecting rod and the connecting column is located at the middle position of the connecting column.
