A method and an apparatus for continuously casting a metal strip are disclosed. In the invention, a molten metal is supplied, by a forcible circulation, into a casting cavity defined between an outer peripheral surface of rotating cooled casting roll and an inner peripheral surface having a substantially U-shaped cross-section of a refractory inner vessel disposed to oppose to said outer peripheral surface with a predetermined gap left therebetween. The molten metal is supplied in such a manner that it flows in the same direction as the direction of rotation of said cooled casting roll so that the molten metal contacts only with the outer peripheral surface of the cooled casting roll over a predetermined circumferential length. As a result, the molten metal is solidified on the outer peripheral surface of the cooled casting roll to form a metal strip. Then, the metal strip is pulled upwardly while being separated from the outer peripheral surface of the cooled casting roll after the metal strip has come out of contact with the molten metal.

Method of and apparatus for continuously casting metal strip

A continuous casting method in which molten metal is continuously poured into a moving mould cavity formed between a rotary casting wheel having a peripheral casting groove and a moving belt partially covering the peripheral casting groove. The cast billet which has been solidified at least outer surfaces thereof is continuously pulled out from the moving mould cavity by means of pinch rollers which are rotated at a peripheral speed greater than that of the rotary casting wheel.
