Description

TECHNICAL FIELD

[0001] The present application relates to the field of semi-continuous casting, in particular to an aluminum alloy deep reheat semi-continuous casting device and method thereof. BACKGROUND

[0002] At present, aluminum alloy casting usually adopts a direct cooling type semi-continuous casting process to produce aluminum alloy round ingots and flat ingots. Liquid aluminum melt is poured into a space surrounded by a crystallizer and a dummy bar head. When the aluminum melt comes into contact with the crystallizer and the dummy bar head, the aluminum melt is cooled by the crystallizer and the dummy bar head and solidifies along the boundary thereof.

[0003] In the related art, the aluminum alloy deep reheat semi-continuous casting device comprises a crystallizer and a tundish arranged above the crystallizer. The tundish is wrapped with a heating ring on the outside. The bottom of the crystallizer is provided with a dummy bar. The crystallizer and the tundish are communicated through a pipette. A flow regulating cone for plugging the pipette is slidingly installed in the tundish. An electric telescopic rod is fixedly connected to the tundish. The extending end of the electric telescopic rod is fixedly connected to the flow regulating cone. A liquid inlet pipe is arranged at the top of the tundish. When the aluminum alloy needs to be cast, the molten aluminum alloy is first poured into the tundish through the liquid inlet pipe. Then the electric telescopic rod is started to drive the flow regulating cone to move, so that the molten aluminum alloy can enter the crystallizer through the pipette and be cooled and cast in the crystallizer. Finally, the solidified aluminum alloy is pulled out through the dummy bar.

[0004] In the related art, in the process of the molten aluminum alloy entering the crystallizer through the pipette, due to the temperature difference between the tundish and the crystallizer, the molten aluminum alloy is easy to form a condensation layer or impurities on the wall of the pipette. This not only reduces the effective flow area of the pipette, but also causes the flow of the molten aluminum alloy to be unstable, thereby affecting the casting efficiency of the aluminum alloy.
