Patent number: 7666347Abstract: A melting apparatus facilitates the melting of pieces of solid metal in a bath of molten metal (10). The melting apparatus comprises a device (18) having a lower portion (22), an upper portion (20), and a body portion (24) extending therebetween. Solid metal is introduced into the device (18) through the upper portion (20). A flow inducer, such as an impeller (28) induces flow of molten metal through the device (18). Flow straighteners, such as baffles (38) encourage axial flow of molten metal through the device (18). The body portion (24) is formed with a plurality of apertures (36) therein and the device (18) is arranged, in use, with the lower portion (22) and the plurality of apertures (36) positioned within the bath (10) and the upper portion (20) positioned above the upper surface (12) and the molten metal bath (10).Type: GrantFiled: March 30, 2005Date of Patent: February 23, 2010Assignee: Advanced Magnesium Technologies Pty LtdInventors: Dag Baekkedal, Jan August Bolstad, Paul McGlade, John Adrian Calvi

Patent number: 7481965Abstract: Apparatus for injecting gas into a vessel including a gas flow duct 31 which receives hot gas through a gas inlet structure 32 at a rear end of the duct. An elongate central structure 33 extends throughout the length of duct 31 and carries a series of vanes 34 for imparting swirl to the gas flow exiting the forward end of the duct. The forward end of the duct 31 has an internally water cooled tip 36 and water flows to and from tip 36 through annular passages 43, 44 in the wall of duct 31. Vanes 34 are mounted on central structure 33 so as to extend to forward ends disposed within the duct tip 36 and are dimensioned such that during operation of the apparatus their forward ends are engaged and supported by the internally water cooled duct tip 36.Type: GrantFiled: October 14, 2005Date of Patent: January 27, 2009Assignee: Technological Resources PTY LimitedInventors: Trevor Williams, John Adrian Calvi
