In order to improve the quality of aluminum and aluminum alloy billets for use in plastic forming, a new vertical semi-continuous casting process has been devised, using a heat insulating mold. In this study, an attempt is performed to clarify the effects of position of solidification interface in the mold on the surface condition of billets at various casting rates in this process. The lower casting rates show the surface condition with scratches and cracks, and the higher rates show a very rough surface, while the inbetween rates show a very smooth surface. The position of solidification interface in the mold could be examined by use of Sn addition and steel wire depth methods. At a moderate casting rate the solidifying surface of billets emerges at the lower end of the mold and solidification then occurres under the condition of no contact of the solidified surface with the mold surface. Consequently the billets with very smooth surfaces are obtained at the specific casting rate.
