Abstract (en)
[origin: JPS6431558A] PURPOSE: To uniformize the quality of a steel strip and to prevent the occurrence of defects by dividedly forming wide width side walls at both sides in the casting range of a mold into a parallel lower side portion and an upper side portion covering the predetermined bath surface and inclining the upper side portion in a specific angle. CONSTITUTION: A cavity is formed with two faced wide width side walls 1, 2 and two faced narrow width side walls 3, 4. At this time, the portion at the side part in the casting range 6 is formed as rectangular connecting surface 9 and a round part 10 is formed at the shifting part to the lower side portion A of the wide width side wall deciding the shape of the steel strip. Further, the upper side portions C, C' covering the expected bath surface 8 are inclined by α=1-3 deg. angle to the vertical line. By this constitution, casting slag is fluidized sufficiently between the mold walls and a casting shell and the friction is reduced. Therefore, the quality of the steel strip over the whole casting width is uniformized, and the occurrence of defects is prevented.
