Method of and apparatus for continuously casting metal strip

An apparatus for continuously casting a metal strip comprising:

• a cooled casting roll mounted rotatably without being immersed in a molten metal;
• a molten metal guiding means for making a molten metal flow down in contact with an outer peripheral surface of said cooled casting roll, said means having an inner peripheral surface of a substantially U-shaped cross-section, when viewed in a plane parallel to a rotating shaft of said cooled casting roll, which opposes and cooperates with the outer peripheral surface of said cooled casting roll in defining therebetween a casting zone over a predetermined circumferential length along the outer peripheral surface of said cooled casting roll, both side edge portions of said inner peripheral surface, as viewed in said cross-section, defining a portion of said casting zone which is located within the breadth of said casting roll, said side edge portions being opposed to and spaced by a predetermined distance from the outer peripheral surface of said cooled casting roll so that a part of the molten metal can overflow laterally therebetween;
• a molten metal circulation means for supplying said molten metal into said casting cavity by a forcible circulation;
• and
• pulling means for pulling the metal strip solidified on the outer peripheral surface of said cooled casting roll while separating the solidifed metal from said cooled casting roll after said solidified strip has come out of contact with said molten metal.
