上面開放水平加熱鋳型式連続鋳造法によるアルミニウムストリップの冷間圧延性に及ぼす凝固組織の影響

抄録

Strips of 99.7% purity aluminum have been produced by open type, horizontal, heated mold continuous casting process (OSC). The strips are rolled by cold rolling, and the mean rolling pressure is measured. The influence of solidified structures on the surface condition and the precision of measurements of the rolled strip is examined. The surface of the sheets obtained, is extremely smooth and flat without any cracks. The thickness of the sheets is uniform irrespective of the rolling direction, when the strips have a unidirectionally solidified structure parallel to the casting direction. However, a lot of intergranular cracks form at the edge of the sheet, when the strips are composed of many crystals.
