    摘要: A method of producing reduced metals is disclosed in which a mixture of a metal oxide and a reducing agent is heated by a burner such that the metal oxide is reduced to a reduced metal. Dry-distilled gas generated during carbonization of an organic matter-containing component is used as fuel for the burner. The sensible heat of exhaust gas evolved by the burner is utilized as heat for carbonizing the organic matter-containing component. Carbide derived by carbonizing the organic matter-containing component is used as the above reducing agent. This method yields excellent cost performance. An apparatus for reducing metal oxides is also disclosed.

    摘要: The present invention provides a method of purifying polluted soil and/or burned ash containing heavy metals and/or organic compounds with a higher throughput than a conventional method. In this method, polluted soil and/or burned ash is dried by, for example, a rotary dryer so that the moisture content is 5% by mass or less, preferably 3% by mass or less, and then large lumps having a particle diameter of 10 mm or more are removed by a vibrating screen. Only an undersize portion is formed into a briquette having a volume of about 6 cm3 by a press molding machine. The briquette is charged in a rotary hearth furnace together with the large lumps, and heated in the furnace to remove or detoxify the heavy metals and organic compounds by evaporation with high efficiency.

    摘要: Disclosed is a method for supplying a granular raw material for reduced iron in which when the granular raw material for reduced iron is fed into a hopper and from there supplied onto a hearth of a movable hearth furnace through a material supplying device, the material supplying device is moved vertically to thereby adjust the gap between the lower end of the material supplying device and the hearth, whereby it is possible to adjust with high accuracy the amount of granular raw material for reduced iron supplied onto the hearth of the movable hearth furnace. Further, disclosed are a method and an apparatus for leveling a granular raw material for reduced iron in which a spiral vane is rotated on the downstream side with respect to a hearth moving direction of a material discharge outlet of a material supplying device for supplying the granular raw material for reduced iron onto a hearth of a movable hearth furnace through the material supplying means to thereby move the granular raw material for reduced iron in the hearth width direction to disperse it, whereby it is possible to disperse and level the granular raw material for reduced iron over the entire surface of the hearth of the movable hearth furnace without breakage or pulverization of the granular raw material for reduced iron.
