NOVELTY - A silicon raw material is dissolved by an electromagnetic induction within a bottomless cooling crucible (2). The obtained molten silicon is pulled down and solidified to obtain polycrystalline silicon. A dummy block (5) is inserted in crucible, a nonflammable component (6) is inserted to the clearance gap formed by block and the crucible in initial-stage dissolution which raises silicon raw material inserted to upper surface of dummy block to the temperature which can be melted by electromagnetic induction of block. Thus, continuous casting of polycrystalline silicon is enabled.    USE - Continuous casting of polycrystalline silicon for solar cell.    ADVANTAGE - The continuous casting of polycrystalline silicon is easily enabled. The continuous casting apparatus smoothly enables pulling-down of polycrystal silicon ingot without generating insertion of molten silicon at the time of initial-stage dissolution of silicon raw material. The polycrystalline silicon ingot is economically manufactured with high quality.    DETAILED DESCRIPTION - A silicon raw material is dissolved by an electromagnetic induction within a bottomless cooling crucible in which at least one portion of axial direction is divided by circumferential direction, and an induction coil (1) is installed. The obtained molten silicon is pulled down and solidified to obtain polycrystalline silicon. A dummy block is inserted in the bottomless cooling crucible, a nonflammable component is inserted to the clearance gap formed by the dummy block and the bottomless cooling crucible in initial-stage dissolution which raises silicon raw material inserted to upper surface of the dummy block to the temperature which can be melted by the electromagnetic induction of the dummy block. Thus, continuous casting of polycrystalline silicon is enabled. An INDEPENDENT CLAIM is included for continuous casting apparatus of polycrystalline silicon, which has electroconductive bottomless cooling crucible, an induction coil which surrounds the bottomless cooling crucible, and an electromagnetic casting apparatus of polycrystalline silicon which pulls down the molten silicon.
