The present invention provides an apparatus for strip casting of molten metal including a pair of casting rollers adapted to receive molten metal along a horizontal axis, wherein a vertical distance separating the pair of casting rollers defines a molding zone; and an electromagnetic edge containment apparatus positioned on each side of the molding zone having an induction coil wound about a portion of a magnetic member to generate magnetic lines of force upon application of a current, wherein the poles of the magnetic member are positioned distal from to aligned to the planar sidewall of the casting rollers and the current provides magnetic lines of force perpendicular to said horizontal axis that contain the molten metal in contact to the casting rollers without substantially increasing the temperature of the molten metal.

A method of making aluminum alloy sheet in a continuous in-line process is provided. A continuously-cast aluminum alloy strip is optionally quenched, hot or warm rolled, annealed or heat-treated in-line, optionally quenched, and preferably coiled, with additional hot, warm or cold rolling steps as needed to reach the desired gauge. The process can be used to make aluminum alloy sheet of T or O temper having the desired properties, in a much shorter processing time. The T or O temper may be selected by annealing the strip to achieve an O temper or solution heat treating the strip to achieve a T temper, and, if a T temper is desired, quenching the strip subsequent to the solution heat treating. The invention further provides a hot or warm rolling step wherein the strip is substantially reduces to a final thickness about 10-65% from a casting thickness.

A method and apparatus for continuous casting of metal strip, the apparatus having (i) a first endless belt supported and moved on the surfaces of a first entry pulley and a first exit pulley and (ii) a second endless belt supported and moved on the surfaces of a second entry pulley and a second exit pulley, with an entry nip defined between the first and second entry pulleys and an exit nip defined between the first and second exit pulleys. Opposing surfaces of the first and second belts progressively diverge from each other in the direction of movement thereof. The apparatus may include a cooled roll in place of the first pulley and first belt with a nip defined between the cooled roll and the second entry pulley.

Method and device for cooling belts of single or twin belt casters. The belt is cooled by a liquid which is contacted with the inner surface of the belt by a system of feed tubes and collection tubes. Liquid is passed out the feed tube, into a channel that communicates with the inner surface of the heated belt, the belt is cooled, and the liquid is removed through collection tubes with a vacuum assist.
