Patent number: 8623270Abstract: A dual outlet injector is disclosed for use in a dual lance or dual port desulfurization station, whereby reagent from a given injector vessel may be injected into two separate supply pipes respectively corresponding to the dual lances or dual ports. The dual outlet injector enables a desulfurization station to be configured comprising only one supply vessel for powdered magnesium reagent and only one supply vessel for a carrier reagent such as powdered lime.Type: GrantFiled: June 30, 2009Date of Patent: January 7, 2014Assignee: ESM Group Inc.Inventors: Joseph R. Waitlevertch, Larry J. Epps, Michael S. Ross

Patent number: 7584876Abstract: A wire injector apparatus for impelling wire or injecting wire is provided. The wire injector has a motorized pulley system connected to a drive wheels for moving the wire laterally through the apparatus. Further, upper and lower idler wheels are arranged about the drive wheels to engage the wire with the drive wheels. A clamp connects the upper idler wheels to the lower idler wheels such that a single actuated lever can control and position multiple upper and/or lower idler wheels. Wire line paths for moving the wire are provided intermediate to the drive wheels and the idler wheels. The arrangement of the components of the wire injector allows for customizing the number of idler wheels and drive wheels to, in turn, provide any number of wire line paths for impelling or injecting any number of wires.Type: GrantFiled: August 17, 2006Date of Patent: September 8, 2009Assignee: ESM Group Inc.Inventors: Joseph R. Waitlevertch, Ronald L. Downard, Frank A. Sokolowski

Patent number: 6010658Abstract: A desulfurization apparatus which employs first and second separate independently movable spaced apart lances (10, 12), each lance having a single conduit (22) through which the desulfurization materials may flow from feed vessels (40, 42, 44, 46) into the molten iron in a ladle (16). First and second independently operable raising and lowering apparatus (28, 30) are provided, the first raising and lowering apparatus (28) being connected to the first lance (10), and the second raising and lowering apparatus (30) being connected to the second lance. Each of the first and second raising and lowering apparatus (28,30) is capable of moving the associated lance (10, 12) from between a raised position where the lower end of the associated lance is spaced above the surface of the molten iron in the ladle and a lowered position where the lower end of the associated lance is spaced within the ladle at a proper location for desulfurization of the molten iron.Type: GrantFiled: November 12, 1998Date of Patent: January 4, 2000Assignee: ESM IIIInventors: Michael S.
