Abstract: PROBLEM TO BE SOLVED: To provide a direct smelting method and a fixed (i.e., non-rotating type) metallurgical vessel for manufacturing metal from supplying material containing the metal. SOLUTION: This method is executed by pouring the solid supplying material together with carrier gas into a fused bath through one or more of lances/ tuyeres 11 extended downward to generate gas stream from the fused bath at least at 0.30 Nm3/s/m2 flow rate in the interface between a metal layer 15 and a slag layer 16 of the fused bath (under static condition).
