  • Patent number: 9252550
    Abstract: A method is for producing an electrode terminal connector for electrically connecting together a positive terminal and a negative terminal of mutually dissimilar metals. The method includes pressing a first plate of a similar metal to the positive terminal to form a mounting hole in the first plate, pressing a second plate of a similar metal to the negative terminal to form a metallic member which is larger in diameter than the mounting hole, and inserting the metallic member into the mounting hole by press fitting to join the first plate and the metallic member together. The method further includes providing the metallic member with an intervening layer of metal having an ionization tendency between an ionization tendency of metal constituting the first plate and an ionization tendency of metal constituting the second plate, and the first plate and the metallic member are joined together via the intervening layer.

  • Publication number: 20150000470
    Abstract: There is proposed a method for preliminary treatment of molten iron wherein heat source for dissolving scrap is ensured sufficiently to improve iron yield while decreasing phosphorus concentration efficiently by suppressing the amount of flux solvent used in the process of desiliconization, dephosphorization and decarburization. In the method for preliminary treatment of molten iron by conducting desiliconization and dephosphorization of molten iron with a converter type container, molten iron is first charged into the converter type container to conduct desiliconization and then intermediate slag removal is conducted, and subsequently a lime-based flux solvent is added to the container while blowing oxygen to conduct dephosphorization of the molten iron, and thereafter newly untreated molten iron is charged into the container to conduct desiliconization, and subsequently the above treatments are repeatedly conducted with the same container.
