PROBLEM TO BE SOLVED: To eliminate a triple point developed at the time of solidifying molten metal by restraining uneven cooling to the molten metal supplied into a mold.;SOLUTION: At crossing parts 45, 45 of the bottom surface 43 with the side surfaces 44, 44 in a recessed groove 42 of a ring mold 41, R parts 46, 46 for controlling a progressing direction of the solidification of the molten metal from this crossing part 45, 45 sides, are arranged. At the time of looking with the cross section crossing at the right angle to the longitudinal direction of the recessed groove 42, the depth H of the recessed groove 42 is made to be 45-70 mm and the curvature radius R of the R parts 46, 46, is made to be 15-35 mm.;COPYRIGHT: (C)2006,JPO&NCIPI
