Patent number: 6732890Abstract: Method precisely, quickly controls flow of molten metal to metal-casting apparatus by pumping, braking or throttling. The Faraday-Ampére principle of current flow in a unidirectional magnetic field is employed. Permanent magnets comprising neodymium or similar high-energy, rare-earth materials provide “reach-out” magnetism. These neo-magnets, usually shown as cubes, are arranged in various powerful configurations driving intense unidirectional magnetic field B across a non-magnetic gap many times larger than economically feasible otherwise. This gap accommodates a conduit for pressurizing and moving a flow of molten metal. In making multiple identical castings, a controlled, intermittent, predetermined flow of molten metal is fed to a series of identical individual molds. The invention obviates needs for operating metallurgical valves or expensive tilting mechanisms for metallurgical furnaces.Type: GrantFiled: February 26, 2002Date of Patent: May 11, 2004Assignee: Hazelett Strip-Casting CorporationInventor: Valery G.

Patent number: 6575226Abstract: Non-rotating, belt-levitating, cylindrical air-pillow method supporting and guiding a moving, tensed, flexible, heat-conductive casting belt along a convex, cylindrically shaped path toward an entrance into a continuous casting machine. Pressurized air is applied in belt-levitating relation to the inner surface of the casting belt moving along the path. Stationary belt-guiding elements define the path. Pressurized air is fed through throttling passages communicating with regions between stationary elements or communicating with outwardly facing stationary plateau surfaces. For reducing flexural stress in the belt moving toward the entrance, a variable radius R+ progressively increases toward the entrance. Escape of pressurized air is restricted by throttling barrier on a perimeter of the belt path. A cylindrical shell supports the stationary elements and is adjacent to a plenum chamber feeding pressurized air through throttling passages in the shell.Type: GrantFiled: April 30, 2002Date of Patent: June 10, 2003Assignee: Hazelett Strip-Casting CorporationInventor: Valery G.

Publication number: 20020190444Abstract: Apparatus, system and method for precisely and quickly controlling the flow of molten metal to metal-casting apparatus, either by pumping or by braking or throttling. The Faraday-Ampére electromagnetic principle of current flow in a unidirectional magnetic field is employed, wherein Faraday's three-finger rule shows pumping direction or throttling direction. Permanent magnets comprising neodymium or similar high-energy, rare-earth materials provide a unique “reach-out” magnetism. These neo-magnets, usually shown as cubes, are arranged in various powerful configurations for driving an intense unidirectional magnetic field B across a non-magnetic gap many times larger than is economically feasible otherwise. This gap accommodates a conduit for pressurizing and moving a flow of molten metal. Molten metal may be pumped to a distributor or a siphon at an entrance to a metal-casting machine.Type: ApplicationFiled: February 26, 2002Publication date: December 19, 2002Inventor: Valery G. Kagan

Pressurized air is applied in belt-levitating relation to the inner surface of the casting belt moving along the path. Stationary belt-guiding elements define the path. Pressurized air is fed through throttling passages communicating with regions between stationary elements or communicating with outwardly facing stationary plateau surfaces. The pressure level of belt-levitating air is at least about 90% but not exceeding 100% of a pressure level which lifts the casting belt away from contact with the stationary elements.Type: ApplicationFiled: April 30, 2002Publication date: September 12, 2002Inventor: Valery G.

Patent number: 5967223Abstract: Permanent-magnetic hydrodynamic methods and apparatus stabilize a moving, flexible, thin-gauge, heat-conducting, magnetically soft ferromagnetic casting belt against thermal distortion while moving along a mold cavity being heated at its front surface by heat coming from molten metal being cast while being cooled at its reverse surface by flowing pumped liquid coolant. Hydro-magnetic devices are arranged in an array wherein flows of pumped coolant pass through fixedly throttling passageways feeding pressure pockets facing the belt's reverse surface. These pockets are shown rimmed by magnetic pole faces. Coolant issues from the pressure pockets as fast-moving films radiating therefrom and travelling in gaps between the belt's reverse surface and the pole faces.Type: GrantFiled: June 30, 1997Date of Patent: October 19, 1999Assignee: Hazelett Strip-Casting CorporationInventors: Valery G.

Patent number: 5804136Abstract: A radial-flow, wide-pouring molten-metal distributor comprising a curved or arcuate overflow weir which is normally horizontal on its top and which is concave on its upstream side as viewed from above. Over this arc-shaped overflow weir flows molten metal to be continuously cast in an open pool. An impetus is thereby imparted to the molten metal along diverging radial lines. The flow so impelled continues radially onto a horizontal apron. The flow spreads fanwise to the desired width which may be as much as six times the width of the weir. Thence, the metal cascades or flows uniformly into the casting apparatus. The overflow weir is preferably supplemented by a skimmer mounted above it in substantially uniform spaced aligned relationship, thereby completing a slot beneath the skimmer through which the molten metal flows. When employed for the casting of wide, thin product, the invention results in a far more uniform and gentle distribution of metal than heretofore available.Type: GrantFiled: November 27, 1996Date of Patent: September 8, 1998Assignee: Hazelett Strip-Casting CorporationInventor: Valery G.
