Zusammenfassung:	PURPOSE: Winnower assembly and a molten metal manufacturing device using the same are provided to minimize the abrasion of conduit lines caused by the blowing of auxiliary fuel and to easily and promptly detect the damage of conduit lines for the blowing of auxiliary fuel. CONSTITUTION: Winnower assembly comprises a gas blowing in-path (12) and a gas blowing-in pipe (20). The gas blowing in-path blows oxygen-bearing gases into a melting gas furnace. The gas blowing-in pipe is installed separately with the gas blowing in-path and blows auxiliary fuel into the melting gas furnace. The gas blowing-in pipe includes two interconnected pipes (26,28a).
