Publication number: 20130059162Abstract: Disclosed are: a flux composition which is used for brazing of a magnesium-containing aluminum alloy material, suppresses the formation of high-melting compounds, provides better wettability, and thereby exhibits better brazability even applied in a small mass of coating; and a brazing sheet using the flux composition. The flux composition for brazing of a magnesium-containing aluminum alloy material includes a flux component [A] containing fluorides as principal components; and an additive [B] being at least one selected from the group consisting of CeF3, BaF2, and ZnSO4. The flux component [A] preferably contains KF in a content of 40 percent by mass or more and 60 percent by mass or less; and AlF3 in a content of 40 percent by mass or more and 60 percent by mass or less.Type: ApplicationFiled: August 24, 2012Publication date: March 7, 2013Applicant: Kabushiki Kaisha Kobe Seiko Sho (Kobe Steel, Ltd.)Inventors: Nobuhiro KOBAYASHI, Motohiro Horiguchi, Kazutaka Kunii, Toshiki Ueda, Shimpei Kimura

Publication number: 20130047787Abstract: Disclosed is a carbon-material-containing iron oxide briquette composition that, when obtaining direct reduced iron by heating in a moving hearth reduction furnace, does not turn into powder in the furnace leading to an accumulation of powder, and reliably prevents the obtained direct reduced iron from turning into powder during conveyance, decreasing yield. Further disclosed are a method for producing same, and a method for producing direct reduced iron using same. The carbon-material-containing iron oxide briquette composition is characterized by: the solidus temperature that is of an Al2O3-CaO—SiO2 ternary system slag in said briquette composition and that is determined by the amount of contained Al2O3, CaO, and SiO2 being no greater than 1300 DEG C.Type: ApplicationFiled: March 24, 2011Publication date: February 28, 2013Applicant: Kabushiki Kaisha Kobe Seiko Sho (Kobe Steel, Ltd.)Inventors: Motohiro Horiguchi, Kazutaka Kunii

Patent number: 8273292Abstract: The present invention provides a steel for machine and structural use which sustains mechanical properties such as strength by reducing S content, and exerts excellent machinability (in particular, tool life) in both of intermittent cutting with HSS tools and continuous cutting with carbide tools. The invention relates to a steel for machine and structural use which contains an oxide inclusion containing, wherein a total mass of an average composition of the oxide inclusions is 100%: CaO: 10 to 55 mass %; SiO2: 20 to 70 mass %; Al2O3: more than 0 and 35 mass % or less; MgO: more than 0 and 20 mass % or less; MnO: more than 0 and 5 mass % or less; and one or more members selected from the group consisting of Li2O, Na2O, K2O, BaO, SrO and TiO2: 0.5 to 20 mass % in total.Type: GrantFiled: January 20, 2009Date of Patent: September 25, 2012Assignee: Kobe Steel, Ltd.Inventors: Koichi Sakamoto, Motohiro Horiguchi, Shogo Murakami, Hiroshi Yaguchi, Shinsuke Masuda, Koichi Akazawa

Patent number: 8192565Abstract: The present invention provides a steel for machine and structural use which is capable of maintaining mechanical characteristics such as strength by reducing a S content as well as of exhibiting excellent machinability (particularly tool life) in intermittent cutting (such as hobbing) with the high speed tool, and a method useful for producing the steel for machine and structural use. The steel for machine and structural use according to the invention secures 0.002% or more of solute N in the steel and has a chemical composition which is appropriately adjusted and satisfies a relationship of the following expression (1): (0.1×[Cr]+[Al])/[O]?150 . . . (1), in which [Cr], [Al], and [0] represent a Cr content (mass %), an Al content (mass %), and an O content (mass %), respectively.Type: GrantFiled: June 23, 2008Date of Patent: June 5, 2012Assignee: Kobe Steel, Ltd.Inventors: Tomokazu Masuda, Takehiro Tsuchida, Masaki Shimamoto, Motohiro Horiguchi, Shinsuke Masuda, Koichi Akazawa, Shogo Murakami, Mutsuhisa Nagahama, Hiroshi Yaguchi, Koichi Sakamoto
