| Number | Title | Issue Date |
| 5660757 | Advanced feed tip nozzle for twin roll caster A molten metal feed tip nozzle for a continuous roll caster is made by combining a pair of elongated feed tip nozzle members with a non-aggressive buffer pad. The feed tip nozzle members are spaced apart a sufficient distance to allow molten metal to pass... | 08/26/1997 |
| 5584336 | Thin gauge roll casting method A method of operation of a twin roll casting apparatus to produce thin gauge sheet metal at high-production rates. The method includes simultaneously adjusting various operating parameters, such as the roll speed, tip position, roll gap, molten metal inpu... | 12/17/1996 |
| 5518064 | Thin gauge roll casting method A method of operation of a twin roll casting apparatus to produce thin gauge sheet metal at high-production rates. The method includes simultaneously adjusting various operating parameters, such as the roll speed, tip position, roll gap, molten metal inpu... | 05/21/1996 |
| 5439704 | Combined coil and blank powder coating A powder coating line for coating either coiled strip or pre-sheared and punched blanks is provided. In order to coat strip a catenary portion of the strip is suspended through a powder coating subsystem which includes a powder coating booth and a curing ... | 08/08/1995 |
| 5413806 | Strip coating machine with thickness control A continuous strip coating machine has top and bottom applicator rolls and a backup roll adjacent the top applicator roll. A lift roll to lift the strip of material and thus vary the angle of wrap of the strip about the bottom applicator roll is provided.... | 05/09/1995 |
| 5228497 | Roll casting machine crown control The crown of roll cast sheet is regulated by controlling the crown of the work rolls in a roll casting machine producing the sheet. The work roll crowns are controlled by providing differential cooling between the center and the ends of the rolls. The wor... | 07/20/1993 |
| 5018966 | Strip drying or curing oven An oven for drying and curing a film of paint, ink, or the like on a continuous strip of metal has a non-rectangular, and preferably oval, elongated oven chamber without sharp internal corners. By avoiding sharp corners in the oven, air flow is more unifo... | 05/28/1991 |
| 4979556 | Thickness control for a continuous caster Thickness of metal sheet being cast is continuously controlled by passing a light beam through the gap between the casting machine rolls and measuring the amount of light passing through. The width of the gap is controlled in response to the measured ligh... | 12/25/1990 |
| 4811781 | Feed tip and continuous casting method using the feed tip The feed tip is provided by a pair of spaced apart refractory bodies defining a feed path for the molten metal. Each refractory body has an upstream portion and a downstream edge and the bodies taper, in cross-section, in a direction towards the downstrea... | 03/14/1989 |
| 4751958 | Continuous casting aluminum alloy A method is provided for continuously casting aluminum alloys having more than two percent total alloying elements by a combination of casting at thinner gauges and much higher speeds than usual. Since remelting in the caster is avoided, sheet quality is ... | 06/21/1988 |
| 4727927 | Casting machine control A dual drive sheet casting machine for casting metal sheet has a pair of water cooled rolls between which the metal is cast. Each roll of the casting machine is driven by a separate motor, with one motor being a master and the other a slave driven at a co... | 03/01/1988 |
| 4681152 | Continuous casting aluminum alloy A method is provided for continuously casting aluminum alloys particularly useful for computer memory disk stock by a combination of casting at thinner gauges and much higher speeds than usual. Sheet quality is vastly improved, surface ripples are avoided... | 07/21/1987 |
| 4641767 | Casting tip assembly with replaceable upstream and downstream units A molten metal feed tip assembly comprises independently replaceable upstream and downstream units. The upstream unit comprises a pair of upstream plates spaced apart by one or more spacers. The downstream unit is preassembled and comprises a pair of spac... | 02/10/1987 |
| 4303181 | Continuous caster feed tip A molten metal feed tip for a continuous caster for aluminum or the like is made by forming a slurry of refractory fibers in an aqueous solution containing a dispersion of colloidal silica. Liquid is extracted from the slurry to form a flexible felt blank... | 12/01/1981 |
| 4242807 | Paint line flotation oven Heat treating apparatus for continuous painted strip, comprising an elongated, convective heating oven through which painted strip is passed while jets of hot gas are directed against the top and bottom surfaces of the strip to dry and cure the paint film... | 01/06/1981 |
| 4232804 | Molten metal feed tip A molten metal feed tip for a continuous caster for aluminum or the like is made by forming a slurry of refractory fibers in an aqueous solution containing a dispersion of colloidal silica. Liquid is extracted from the slurry to form a flexible felt blank... | 11/11/1980 |
| 4054173 | Apparatus for producing completely recrystallized metal sheet A method and apparatus for producing extremely fine-grained aluminum sheet in a casting machine having a pair of parallel casting rolls, a pouring tip on the entrance side of the rolls, and means for driving the rolls. Molten aluminum is poured through th... | 10/18/1977 |
