摘要： Provided is a smelting method whereby a reaction for reducing pellets, said pellet being formed by using a saprolite ore as a starting material, can be effectively conducted and thus an iron/nickel alloy having a nickel grade of, for example, 16% or greater can be obtained. The method comprises: a pellet production step (S1) for producing the pellets from the saprolite ore; and a reduction step (S2) for heating and reducing the obtained pellets in a smelting furnace. In the pellet production step (S1), at least the saprolite ore and a preset amount of a carbonaceous reducing agent are mixed together to produce the pellets. In the reduction step (S2), a hearth carbonaceous reducing agent is preliminarily spread on the hearth of the smelting furnace and the pellets produced above are placed on the hearth carbonaceous reducing agent and then subjected to a heat reduction treatment.

摘要： A method for reducing molten raw materials, includes placing the raw materials, in a solid or molten state, on an inductively heated bed with coke pieces. The reduced melt that runs off the coke bed is collected and the waste gases are discharged. A coke bed is inwardly limited by a tube-shaped element through which the reaction gases are drawn off via a plurality of draw-off openings in the tube-shaped element. The corresponding device has a reactor for a bed with coke pieces and an induction heater with at least one induction coil. The reactor has a loading opening and a discharge opening for the treated melt. The coke bed is ring-shaped around a tube-shaped element. The material of the tube-shaped element allows inductive coupling to the induction field of the induction coil and it has draw-off openings for drawing off reaction gases from the coke bed.

摘要： A method for smelting a nickel oxide ore, wherein the reduction step progresses effectively while maintaining the strength of the pellets, comprises: a pellet production step S1 for producing pellets from a nickel oxide ore; and a reduction step S2 for reducing and heating the obtained pellets in a smelting furnace at a predetermined reduction temperature. In the pellet production step S1, a mixture is formed by mixing materials including said nickel oxide ore without mixing a carbonaceous reducing agent, and the pellets are formed by agglomerating said mixture. In the reduction step S2, in charging the obtained pellets into the smelting furnace, a carbonaceous reducing agent is spread in advance over the furnace floor of the smelting furnace and the pellets are placed on the carbonaceous reducing agent, and the pellets are reduced and heated in a state where the pellets are covered by the carbonaceous reducing agent.
