PCT No. PCT/JP84/00339 Sec. 371 Date Feb. 28, 1985 Sec. 102(e) Date Feb. 28, 1985 PCT Filed Jun. 29, 1984 PCT Pub. No. WO85/00125 PCT Pub. Date Jan. 17, 1985.A belt-converging type continuous casting apparatus for the continuous production of sheet bar-like cast sheet, wherein a casting space is defined by a combination of a pair of metal belts for supporting broad side planes of the cast sheet arranged opposite to each other with circulatedly moving, and a pair of tapered fixed-type side plates for supporting narrow-side planes of the cast sheet each disposed between the metal belts in intimate contact therewith, and is characterized in that the shape of the side plate is designed so as to satisfy the following relations: d=5-300 mm, D>/=60 mm, D/d</=16, theta </=30 DEG theta =tan-1 (D-d/H to thereby prevent the occurrence of defects in the side planes of the cast sheet, while the metal belt is selected so as to satisfy the following relations: Sy>/=10,500 t/Dr, 0.4</=t</=2.5, wherein Dr is a diameter of a guide roll (mm), to thereby prevent the deterioration of cast sheet quality and the casting accident accompanied with the deformation of the belt.
