摘要： In a method for producing a molten steel according to one aspect of the present invention, the solid-state direct reduced iron contains 3.0% by mass or more of SiO2 and Al2O3 in total and 1.0% by mass or more of carbon. A ratio of a metallic iron to the total iron content contained in the solid-state direct reduced iron is 90% by mass or more, and an excess carbon content Cx is 0.2% by mass or more to the carbons contained in the solid-state direct reduced iron. The method includes a step in a first furnace of melting 40 to 100% by mass of the solid-state direct reduced iron, and separating a molten pig iron having a carbon content of 2.0 to 5.0% by mass and a temperature of 1350 to 1550° C. and a slag having a basicity of 1.0 to 1.4 and a step in a second furnace of melting a remainder of the solid reduced iron together with the molten pig iron separated in the first furnace and blowing oxygen onto the molten material to decarburize into a molten steel.

摘要： A metal powder manufacturing device for manufacturing a metal powder includes a feed for supplying a molten metal, a fluid spout unit, and a course modification unit. The fluid spout unit further includes a channel and an orifice. The channel is provided below the feed, allowing passing of the molten metal supplied from the feed. The orifice is opened at a bottom end of the channel, spouting a fluid into the channel. The above course modification unit is provided below the fluid spout unit, and forcibly changes the traveling direction of a dispersion liquid. This dispersion liquid is composed of multiple fine droplets dispersed into the fluid. The above droplets are a resultant of a breakup caused by a contact between the molten metal and the fluid ejected from the orifice. Here, the dispersion liquid is transported so that the droplets is cooled and solidified in the dispersion liquid in order to manufacture the metal powder.

摘要： A technique for producing iron utilizes agglomerations, such as briquettes or tablets, or powders, that include a sulfur-containing material such as iron sulfide, and and oxygen containing material such as iron oxide. The agglomerations or powders are substantially free of chemical binders and utilize iron and aluminum metal powders and pressure for compaction on either roll presses or tablet machines. Addition of metal powders provides rapid dissolution of the alloy and improved heat transfer. Iron sulfide agglomerations also provide consistent and improved sulfur recoveries compared to granulated iron sulfide additions with little to no sulfur odor.
