Patent number: 11097339Abstract: A casting plant to produce a cast product with a high quality and a method for managing data for molding the mold and data on the conditions of the molten metal in the casting plant are provided. The controller (11) for the molding unit issues a serial number for the mold to a mold (M). The controller (31) for the unit for conveying the molds shifts the serial number for the mold in accordance with a movement of the mold. It also gathers data on the mold and links the data for molding the mold with the serial number for the mold. When the molten metal is poured from the ladle into the mold, the controller (71) for the unit for pouring the molten metal sends to the computer (91) for controlling the casting plant the serial number for the ladle that is linked with the data on the conditions of the molten metal and that is linked with the serial number for the mold.Type: GrantFiled: November 16, 2015Date of Patent: August 24, 2021Assignees: SINTOKOGIO, LTD., FUJIWA DENKI CO., LTD.Inventors: Tadashi Nishida, Toshiyuki Hyodo, Koichi Kato, Kazuhiro Ota
