    • PROBLEM TO BE SOLVED: To provide a system where nickel can be recovered from nickel plating sludge at a recovery of ≥80%, and can be recycled as useful resources. SOLUTION: The method comprises: a drying stage where recovered nickel plating sludge is heated, so as to reduce a water content therein; an oxidizing stage where the obtained dry nickel plating sludge is heated at high temperature and is oxidized, so as to be nickel oxide-containing lumpy matter; a preliminary reducing stage where the obtained lumpy matter is pulverized, is thereafter heated together with a carbon source, and is subjected to preliminary reducing; a melting-reducing stage where the obtained preliminarily reduced product is heated and melted together with the carbon source; and a recovering stage where the melted and reduced metal nickel is recovered. Upon the heating and melting for the preliminarily reduced product, it is possible that shell powder is charged, and dephosphorization and desulfurization are jointly performed. Also, it is possible that the nickel plating sludge obtained through the drying stage is accumulated, and after its storage by a fixed amount, the treatments on and after the oxidizing stage are continuously performed.

    • 要解决的问题:提供镍回收率高于80%的镍电池回收系统,可作为有用资源回收利用。 解决方案:该方法包括:将回收的镍电镀污泥加热的干燥阶段,以减少其中的含水量; 所得到的干镍电镀污泥在高温下被加热并被氧化的氧化阶段,以便是含氧化镍的块状物质; 将得到的块状物粉碎的初步还原阶段随后与碳源一起加热,进行初步还原; 将得到的预缩合物与碳源一起加热熔融的熔融还原阶段; 以及回收熔融和还原的金属镍的回收阶段。 对于预先还原的产物进行加热熔化,可以将壳粉末装入,脱磷脱硫一起进行。 此外,通过干燥阶段获得的镀镍污泥可能被累积,并且在其保存一定量之后,连续进行氧化阶段和之后的处理。 版权所有(C)2007,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a wire saw which has excellent sharpness and which hardly causes clogging by chippings.SOLUTION: A wire saw includes a body 6 which has a first metal wire 1 made of a cobalt group alloy, two second metal wires 2a and 2b made of the cobalt group alloy, and three third metal wires 3a-3c wound around the first metal wire 1 and made of the cobalt group alloy. The second metal wires 2a and 2b spirally cross each other in directions opposite to each other, and are wound around the third metal wires 3a-3c, respectively. A cutting blade is composed of a protrusion 8 formed of an intersection point of the two second metal wires 2a and 2b.
