Patent number: 10415884Abstract: A method of fluxing or degassing a molten metal residing as a bath in a furnace. The bath of molten metal includes a bath surface height and the method provides at least one rotating impeller in the molten metal bath to initiate a flow of the molten metal. The flow in the molten metal results in elevating a portion of the molten metal above the bath surface height where at least one of a fluxing agent and an inert gas is introduced into the elevated portion of the molten metal.Type: GrantFiled: May 14, 2014Date of Patent: September 17, 2019Assignee: PYROTEK, INC.Inventors: David Schlicht, Andrew Horsfall, Richard S. Henderson, Lennard Lutes

Patent number: 9273376Abstract: A flux injector apparatus and method adapted to distribute a predetermined amount of flux to an associated pool of molten aluminum. The flux injector apparatus includes a pressurized tank adapted to store and feed the flux under pressure. A feed mechanism operative to discharge a predetermined amount of flux to an outlet and a controller for monitoring and operating the apparatus. The feed mechanism includes a housing having an inner wall defining a cavity with an inlet and an outlet. A feed wheel is positioned within the cavity and operative to receive a predetermined amount of flux from the inlet, translate the flux within the cavity and discharge the predetermined amount of flux through the outlet of the pressurized tank.Type: GrantFiled: June 7, 2012Date of Patent: March 1, 2016Assignee: PYROTEK INC.Inventors: Lennard Lutes, Richard S.

Publication number: 20050285317Abstract: A transfer pipe for molten metal includes a pipe wall comprised of graphite or ceramic. The graphite ceramic pipe wall can be surrounded by a pipe wall comprising a low thermally conductive material. Both the graphite or ceramic pipe wall and the low thermally conductive pipe wall can be encased in a rigid wall, for example steel. The transfer pipe can communicate with a molten metal pump to provide a system for moving molten metal.Type: ApplicationFiled: June 24, 2004Publication date: December 29, 2005Inventors: Richard Henderson, Richard Chandler, George Mordue, Paul Campbell, Lennard Lutes, Harvey Martin
