Description

Technical Field

[0001] The present invention relates to the technical field of casting, and particularly relates to an automatic casting device for castings. Background Art

[0002] In the casting process, raw materials need to be heated and melted at high temperature in a smelting furnace. Subsequently, a special ladle is used as a medium to inject the molten material into a preset mold cavity.

[0003] The molten metal flows from the forehearth into the ladle, and some slag is inevitably carried in. Therefore, all the molten slag in the ladle must be removed before casting to prevent the slag from entering the mold and causing slag hole defects. Specifically, "skimming" operation is carried out in the ladle. When performing the skimming operation, a more effective method is to first sprinkle a slag collector on the surface of the molten metal in the ladle, so that the slag sticks to the semi-molten slag collector, and then it can be picked out or scraped out with an iron rod. However, the above skimming operations are basically manually completed by workers approaching the high-temperature ladle, which will cause physical harm and other safety problems to the workers.
