Patent number: 9289824Abstract: The present invention provides pouring equipment of a tilting-type that can appropriately pour molten metal at a high speed corresponding to the speed of molding. It also provides a method of pouring the molten metal. The pouring equipment has a holding furnace supplying the molten metal by being tilted, a pouring ladle pouring the molten metal supplied from the holding furnace into molds that are intermittently transported, a device for measuring weight of the molten metal in the pouring ladle, and equipment for control that controls the tiltings of the holding furnace and the pouring ladle. The equipment for control has a device for storing results from measurements and devices for calculating the first and second flow rate. The equipment controls the tilting of the ladle so that the ladle pours the molten metal into the mold according to the flow pattern of the product.Type: GrantFiled: June 29, 2011Date of Patent: March 22, 2016Assignees: SINTOKOGIO, LTD., FUJIWA DENKI CO., LTD.Inventors: Kouichi Banno, Toshiyuki Hyoudo, Tadashi Nishida, Hideto Terada

Patent number: 9289825Abstract: To transfer the molten metal that is melted in the melting furnace into the pouring ladle, which is a vessel for transporting the molten metal to the place for pouring, and to further lift the pouring ladle by another crane to pour the molten metal, requires time, such that the molten metal that had a high temperature when melted by the melting furnace is likely to cool down and to cause a defective cast product. To solve the problem the pouring equipment of the present invention pours the molten metal into the mold, comprising the melting furnace that produces molten metal by melting metal material and a driving apparatus that can move the melting furnace backward and forward or in a traverse direction, wherein the pouring equipment moves the melting furnace to the predetermined position by the driving apparatus, and then pours the molten metal into a mold by tilting the melting furnace relative to the mold.Type: GrantFiled: November 29, 2010Date of Patent: March 22, 2016Assignees: SINTOKOGIO, LTD., FUJIWA DENKI CO., LTD.Inventor: Hideto Terada
