PURPOSE:To perform titled width changing easily with high dimensional accuracy by moving a width changing member disposed with plural short side cooling members of different rates of recess in the ingot width direction in the direction parallel with the thickness direction of the ingot. CONSTITUTION:A width changing member 3 having plural short side cooling members 4a, 4b, 4c, of mutually different rates of recess in the ingot width direction disposed along the ingot moving direction and a back frame 5 is moved in the direction inersecting orthogonally with the ingot drawing direction and parallel with the ingot thickness direction. Either one of the members 4a, 4b, 4c for example, 4b, is positioned in contact with long side cooling member 1, whereby the mold having the mold width size corresponding to the rate of recess of the member 4b is constitutded. Projections are provided in different positions of the frame 5, so that they are put in abutment on the stoppers installed in prescribed different positions by the movement of the frame 5, whereby the positioning of the members 4a, 4b, 4c with respect to the member 1 is accomplished. |
