摘要： PROBLEM TO BE SOLVED: To provide a direct smelting process and an apparatus therefor for producing a molten metal from an iron-containing material that can achieve a high efficiency for heat transfer.SOLUTION: A feed material which includes a solid material and a carrier gas is injected into molten baths 22 and 23 at a velocity of at least 40 m/s through a solid injection lance 27 arranged so that the central axis is at an angle of 20 to 90 degrees downward with respect to the horizontal axis. The feed material injection generates a surface 25 gas flow of at least 0.04 Nm/s/min the molten baths 22 and 23 at least in part by reactions of the material injected in the baths 22 and 23. The gas flow causes the molten material to be projected upwardly as splashes, droplets and streams, and forms an expanded molten bath zone 28, with the gas flow and the upwardly projected molten material causing substantial movement of the material in the molten bath 23 and strong mixing of the molten bath 23.

摘要： PROBLEM TO BE SOLVED: To provide a supply means of solid feed materials having efficiency and reliability for injecting the solid feed materials into a direct smelting vessel during Hismelt (R) process operation. SOLUTION: A solid material feeding means 31 for injecting the solid feed materials, that is, carbonaceous materials into a direct smelting vessel SRV as a facility, independently feeds the carbonaceous materials into the plurality of injecting lances 7a, 7b. The independent supply of the carbonaceous materials minimizes the possible adverse impact of breakdowns of the carbonaceous material injection means for one or more of lances or of one or more lances.
