Description

Technical Field

[0001] The utility model relates to the technical field of loading and unloading slings, in particular to a loading and unloading sling used for the production of aluminum alloy cast bars. Background Art

[0002] In semi-continuous casting, commonly used in aluminum alloy processing, the aluminum alloy melt is uniformly introduced into a water-cooled mold. It solidifies and crystallizes under the action of the mold walls and base, forming a relatively solidified shell. When the horizontal liquid level of the molten metal in the mold reaches a preset height, the casting machine's traction mechanism drives the base and the solidified shell on the base downward at a constant speed. The solidified ingot portion that has emerged from the mold is immediately cooled directly by cooling water, and the ingot's crystalline layer continuously advances toward the center, where it completely solidifies and crystallizes. Once the ingot reaches the specified length, casting is stopped, the ingot rod is removed, and the casting machine base returns to its original position, completing a casting run. The aluminum alloy ingot is then hoisted to the designated location using a hoist.

[0003] Since some aluminum alloy cast bars are not placed neatly, they need to be manually straightened before lifting, which is very inconvenient, time-consuming and labor-intensive, and affects the efficiency of lifting and loading and unloading. Therefore, those skilled in the art provide a loading and unloading sling for the production of aluminum alloy cast bars to solve the problems raised in the above background technology.
