ABSTRACT A mold for the continuous casting of metal to a sheet-like strand is provided with a casting passage having a slot-shaped outlet end. The inlet end of the casting passage is considerably wider, and has a much larger area, than the outlet end. This facilitates pouring of molten metal into the mold and permits the use of casting techniques such as shrouding which enhance the continuous casting process and/or the quality of the strand. The cross- sectional area of the casting passage decreases progressively from the area at the inlet end to that at the outlet end over at least a portion of the length of the mold. The circumference of the casting passage, however, remains at least approximately constant as the area decreases. This enables the strand to be drawn through the mold without difficulty. A continuous casting method involves pouring molten metal into a casting passage, and partially solidifying the molten metal to form a strand which is drawn through the casting passage. The cross-sectional area of the strand is reduced between upstream and downstream locations of the casting passage while maintaining the circumference of the strand at least approximately constant. The reduction in cross-sectional area is carried out in such a manner that the strand has a sheet-like configuration upon exiting the casting passage. - 1 -
