アルミニウム連続鋳造スラブの鋳塊底部形状に及ぼす鋳造条件の影響 The effect of casting conditions on the butt shape of DC aluminum slab
The effect of casting conditions on the butt shape of DC aluminum slab was investigated by measurement of the butt curl, the bow and the bow height after casting. The butt curl started from secondary cooling point, and increased with the side shell growth. For example the butt curl increased with casting speed or casting temperature. Also, it became clear that the bow occurred by narrow side shell inclining to inside, the butt curl and the bow were in a body. The relations of the bow and casting conditions had same tendency as that of the butt curl and them. In addition, the bow height was seriously affected by the effective mold length because the bow height depended on the distance from the secondary cooling point to the top of narrow side shell.
