摘要： A method of melting tinned iron scrap, in which loosely packed, tinned iron scrap is used as part of iron scrap to be melted while the amount of a combustion assisting gas supplied through a secondary tuyere is adjusted to control a secondary burning rate of the gas, and a method of melting a tinned iron scrap, in which tinned iron scrap is charged before iron scrap other than tinned so that the former may be interposed between the latter and a coke-filled layer. According to the method of melting, a single furnace enables recovering high-energy exhaust gas while manufacturing hot metal, which has a low Sn content and can be used for manufacture of high grade steel, without the aditional steps of detinning and pouring of two ladles and without the use of expensive electric power. In addition, an exhaust gas dust containing a concentrated SnO2 can be effectively used as a Sn source. Accordingly, this method can be applied to a field, in which city scrap such as surface-treated steel or the like is melted.

摘要： A gasification melting furnace which is used to prevent the occurring of low-temperature regions in the gasification melting furnace and concentrate a firing point for incineration of wastes, and which comprises a vertically-movable furnace-center lance for blowing a combustion-support gas downward along a furnace shaft into the furnace, an upper tuyere in at least one stage so disposed as to deviate a combustion-support gas blowing angle from a furnace shaft direction, and a lower tuyere in at least one stage installed so as to project into the inside of the furnace at a location for blowing the combustion-support gas or the combustion-support gas and fuel toward the furnace shaft, whereby it is possible to recover constantly high-value-added molten slag and various metals and energy gas. When a ratio of firing point diameter: df formed by the furnace-center lance to a furnace inner diameter: D is so controlled by vertically moving the lance as to be df/D≤0.6, the firing point can be further concentrated in incinerating wastes to thereby ensure more stable recovery of high-value-added molten slag and various metals and energy gas.

摘要： Disclosed is a means for efficiently collecting a platinum group element by efficiently enriching the platinum group element in a molten copper phase produced from a copper iron scrap containing the platinum group element. Specifically disclosed is a method comprising: melting a copper iron scrap containing a platinum group element to produce a molten material; separating the molten material into two phases i.e. a molten copper phase containing at least one rare metal selected from the group consisting of Nd Pr and Dy and a molten iron phase having a carbon concentration of 1 mass% or more wherein carbon contained in the molten iron phase is derived from a carbon source contained in the molten material; isolating the two phases from each other and collecting the molten copper phase; and separating and collecting the platinum group element dissolved in the molten copper phase from the molten copper phase. The copper iron scrap may contain the rare metal. Alternatively a member containing the rare metal may be added to the molten material. It is preferred that the total concentration of the rare metal contained in the molten copper phase be 1 mass% or more.

摘要： A method and apparatus for treating waste, capable of solving problems of (a) stoppage of a duct, (b) time for charging waste in a furnace, (c) discharge of unused carbon, (d) control of a waste upper-face position, (e) recycling of halogen class materials, (f) charging of harmful waste materials, and (g) rise in internal pressure in a basin chamber. A waste treatment furnace comprises a furnace body, a gas outlet provided in the upper part of the furnace body, an outlet for molten slag and/or molten metal, located in the lower part of the furnace body, a waste inlet provided between the outlet for molten slag and/or molten metal and the gas outlet, a furnace center lance provided in the upper part of the furnace body along the furnace axis and for blowing a burn-assisting gas downward into the furnace, an upper tuyere arranged in more than one step in the furnace wall between the waste inlet and the gas outlet, and a tuyere arranged in more than one step in the furnace wall between the waste inlet and the outlet for molten slag and/or molten metal. When waste is charged into the waste treatment furnace to perform at least one of the treatments of burning, gasification, and melting, discharge gas generated in the at least one of the treatments is cooled in the furnace in the vicinity of the inlet of a duct that is connected to the furnace body of the waste treatment furnace and guides discharge gas to outside the furnace body.
