Description

Technical Field

[0001] The utility model relates to the technical field of aluminum liquid slag removal devices, in particular to a slag removal mechanism for an aluminum smelting furnace. Background Art

[0002] Before aluminum ingots are formed, solid aluminum blocks need to be melted into aluminum liquid, and then the aluminum liquid is poured into a mold to make aluminum ingots. In the process of melting the aluminum blocks into aluminum liquid, impurities will float on the surface of the aluminum liquid, and workers are required to remove the impurities. Generally, the furnace for melting aluminum blocks will have a hole for workers to remove slag. The tool used is a slag scoop. Workers need to use the slag scoop to scrape the impurities over and then remove them. During this process, workers need to adjust their positions. Due to the high temperature of the smelting furnace and the limited length of the slag scoop, workers need to stretch their arms when slagging impurities near the internal area. The scorching temperature makes it unbearable for workers and is highly dangerous.

[0003] The existing technology has the following problems:

[0004] After extensive searching, it was found that Chinese Patent Publication No.: CN219454679U discloses a slag removal device for molten aluminum. The above patent still has some problems in actual use. The most obvious one is that when workers use a slag scoop to remove impurities in actual use, it is difficult to adjust the slag scoop position according to actual slag removal needs because the length of the slag scoop is fixed, resulting in the problem that workers need to stretch their arms when slag removal of impurities near the internal area.
