Patent number: 6036745Abstract: In a charge well for adding scrap metal pieces or particles to a molten metal bath, a stationary diverter is provided within a charge well for diverting the circular flow of molten metal, caused by the orientation of the inlet port, in a downward direction, thereby creating a downward flow of molten metal which results in quick and efficient submergence of incoming lightweight scrap metal pieces or particles. Preferably, the diverter includes a leading edge which extends in a generally radial direction within the charge well and a flat top surface which tapers from the leading edge to a point or narrowed trailing edge. A downward curved surface extends from the leading edge to facilitate the downward flow of molten metal. The diverter may be mounted on a support member extending above the charge well.Type: GrantFiled: January 17, 1997Date of Patent: March 14, 2000Assignee: Metaullics Systems Co., L.P.Inventors: Ronald E.

Patent number: 5558505Abstract: A post for a molten metal pump having an end joined to a hole in a pump base. The post end includes a longitudinal bore opening at the end of the post and a port opening to the side of the post intersecting the bore. A plug is inserted into the bore above the level of the port yet leaving a portion of the upper bore open. Cement can be injected into the bore and out the ports. Thereafter, a second plug can be inserted into the bore to drive cement out. To remove the post, it is cut across its longitudinal axis to expose the open upper portion of the bore. The opening is a pilot hole to drill a longitudinal hole in the post. A device having two members connected by a rod are attached to the upper and lower surfaces of the remaining post, respectively and tightened to break the cement joint.Type: GrantFiled: August 9, 1994Date of Patent: September 24, 1996Assignee: Metaullics Systems Co., L.P.Inventors: George S.
