Description

Technical Field

[0001] The utility model relates to the technical field of molten aluminum transfer devices, in particular to a molten aluminum transfer bag preheating device. Background Art

[0002] The aluminum ladle is one of the main equipment for aluminum water transfer. Before the aluminum water ladle is injected, the aluminum ladle needs to be preheated to prevent the high-temperature aluminum water from condensing into aluminum slag when it is cooled, which makes the aluminum water casting unusable. However, the existing preheating method is mainly to open the lid of the aluminum ladle, and then extend the burner into the aluminum ladle to burn and heat the inside of the aluminum ladle. It usually takes a week to complete the preheating. Not only is the efficiency low, but the aluminum ladle will lose a lot of heat during preheating because the lid of the aluminum ladle is opened, which ultimately leads to a long preheating time for the aluminum ladle and a large amount of energy is wasted. Therefore, in view of the above shortcomings, a preheating device for aluminum water transfer ladle is proposed. Utility Model Content
