| Research Abstract |
Improvement of deterioration of the aluminum alloy body sheet caused by impurity was tried using a high speed twin roll caster. The impurity became fine by the effect of the rapid solidification. Therefore, the deterioration could be eliminated. When the high speed twin roll caster was used, aluminum alloy for the casting could be cast in to the sheet, and this sheet had sound formability of deep drawing. The deterioration by impurity of the aluminum alloy for casting could be prevented by rapid solidification by the high speed twin roll caster. The high speed twin roll caster was adapted on Al-Mg alloy. The high speed twin roll caster was useful for the prevention of the deterioration of mechanical property by the impurity.
