Abstract: A method for discharging a reduced product produced on a movable hearth of a movable-hearth furnace uses a discharging device. The discharging device includes a removal unit for removing the reduced product from the movable hearth, a separation unit for separating the reduced product from a solid reductant, a leaving-returning unit for either leaving substances other than the reduced product on a solid reductant layer or returning the substances onto the solid reductant layer, and a discharge unit for discharging the reduced product to the outside of the movable-hearth furnace.

Abstract: Traveling hearth furnace and an operating method thereof, which, when stacking a layer consisting of a mixture of oxides such as fine iron ore and a fine solid reducing material onto a horizontally traveling hearth and reducing the oxides through radiant heat transfer from above the hearth, is based on melting the reduction product in the course of up to a discharge port, and causing aggregation and separation of slag in from the reduction product, followed by solidifying the reducible material.

Abstract: A mixed layer of fine ore and coal char and a layer of fine coal are stacked on a hearth in the form of separate layers from each other. The fine ore is reduced while fine coal is pyrolyzed to produce coal char. The produced coal char is used repeatedly.

Abstract: With a solid fine reducing material containing hydrogen placed as a lower layer on a movable hearth, a powdered mixture of an oxide powder dominantly of a fine iron ore and a solid fine reducing material is stacked in layered arrangement, and subsequent reduction operation is performed.

Abstract: A traveling hearth for producing reduced metal by charging and stacking a raw material containing a metal-containing material and a solid-reducing material on a horizontally moving hearth, arranged for disposing a solid-reducing material layer on the hearth, forming concave portions at the solid-reducing material surface, stacking the raw material on the surface of the solid-reducing material layer, reducing the raw material by at least once heating and melting the material on the hearth to separate metal and gangue and ash ingredients, and discharging metal from the hearth.

Abstract: A feed stock composed of an iron ore and a solid reducing material is supplied in a movable hearth furnace provided with a unidirectionally movable hearth, stacked on the movable hearth and then subjected to a series of operations of preheating, reduction and discharge. To this end, a feed stock subsequently supplied in such furnace is preheated by utilizing a heat applied by the finished reduced ore and is stacked on the movable hearth.

Abstract: A method and a device for monitoring combustion conditions in a metallurgical furnace which is effective and simple in structure and can provide a wide monitoring range of high accuracy. The combustion conditions in the furnace are monitored by a probe lying oblique to the axis of the blow pipe. Toward this end, the probe is inserted into the furnace through a tuyere. The tuyere has a through opening admitting the probe and allows the probe in an orientation oblique to the radii of the blow pipe.
