Summary:PURPOSE:To prevent the generation of breakout, by disposing belt type molds under a mold gate, and extending the bottom end part on the inside circumferential surface of the mold gate to the part near the horizontal line passing the axial centers of the upper support rolls of the mold. CONSTITUTION:A pair of belt type molds 14 of long side are disposed right under the long sides of a mold gate 8. The molds 14 are constituted of a pair of upper and lower support rolls 15, 16, and endless steel belts 17 wound between both rolls 15 and 16, and contact with the gate 8 at about <=0.1mm. spacing alpha. The gate 8 consists of heat resistant bricks 9 and a steel box 10, and a porous sealing member 12 is disposed in the sealing chamber 11 thereof. The bottom end part on the inside circumferential part of the gate 8 is extended to the part near the horizontal line (a) running the axial centers of the rolls 15. The shell 7A of an ingot 7 is thus kept free from a straightening effect, whereby the generation of crack is prevented and the possibility of breakout is eliminated.
