Title:
MOLTEN METAL SUPPLY DEVICE AND METHOD FOR CLEANING DUCT THEREOF
Document Type and Number:
WIPO Patent Application WO/2011/052138
Kind Code:
A1
Abstract:
The disclosed molten metal supply device supplies a set amount of molten metal (12) each repetition of a short cycle through a simple operation, and enables the detachment of the oxide of the molten metal (12) adhered to the inner surface of a duct. The molten metal supply device, wherein the duct (1) is provided with an inductor (14), applies thrust to the molten metal (12) within the duct (1) by means of said inductor (14), thus supplying said molten metal (12), and is provided with: a hot-liquid supply inductor (14) for supplying by applying thrust to the molten metal (12) within the duct (1); and a startup inductor (24) that has the heat resistance needed to pump the molten metal (12) within the duct (1) to the height of the hot-liquid supply inductor. The startup inductor (24) is disposed at a lower position than the liquid level of the molten metal (12). Furthermore, the oxide of the molten metal (12) adhered to the inner surface of the duct (1) is forcibly detached by means of the hot-liquid supply inductor (14) and the startup inductor (24) supplying the molten metal (12) to the transportation destination and being able to drive the molten metal (12) in the opposite direction.
