The first barrel 100 is hollow inside, and the top of the first barrel 100 is open, so that the inner wall of the first barrel 100 can be enclosed to form a receiving cavity for receiving molten metal, and the molten metal can be injected into the receiving cavity, so that the staff can move the molten metal by moving the first barrel 100. The interior of the second cylinder 200 is hollow, and the top end of the second cylinder 200 is opened, so that the second cylinder 200 can be covered on the first cylinder 100. A cooling cavity capable of accommodating cooling water is provided on the side wall and the bottom wall of the second cylinder 200, so that the cooling cavity can be covered on the outer wall of the first cylinder 100, so that the first cylinder 100 can be cooled by injecting cooling water into the cooling cavity, and then the metal melt in the accommodating cavity can be cooled, and then the metal melt can be cooled in advance while moving the metal melt, thereby reducing the subsequent post-furnace cooling time. The interior of the third cylinder 300 is hollow, and the top end is opened, so that the third cylinder 300 can be covered on the second cylinder 200. The side walls and bottom walls of the third cylinder 300 are provided with an insulating cavity that can isolate the second cylinder 200, so that the insulating cavity is covered on the outer wall of the second cylinder 200, and the second cylinder 200 and the third cylinder 300 are separated by the insulating cavity to achieve the purpose of heat insulation, so that the temperature of the second cylinder 200 in contact with the first cylinder 100 can be much lower than the temperature of the third cylinder 300, thereby playing a protective role, thereby preventing the staff from getting scalded when moving the molten metal. The moving part 400 is arranged on the outer wall of the third cylinder 300.
