Patent number: 9920390Abstract: 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.Type: GrantFiled: January 17, 2013Date of Patent: March 20, 2018Assignee: JFE STEEL CORPORATIONInventors: Yozo Iwaki, Shizuhiko Ikeno, Kochiro Ejima, Takeshi Ishii, Masanori Nishikori, Hironori Fukushima, Naoki Kikuchi, Norihiko Suzuki, Kotaro Tanaka, Kazuhito Yamamoto, Ryo Kawabata, Naotaka Sasaki, Yasushi Ogasawara, Futoshi Ogasawara, Yuichi Uchida, Masaomi Senoo, Manabu Tano
