Abstract
An electromagnetic mold for vertical continuous casting of rolling slabs, featuring an inductor and an electromagnetic screen partly covering the induction is such that the vertical distance between the lower edge of the inductor and the lower edge of the screen is greater at the narrow sides of the mold than at the broad sides of the mold. As a result of this arrangement it is possible to prevent metal running out of the ingot head at the narrow sides during the start-up phase. The foregoing is achieved at the expense of an insignificant amount of melt circulation occurring in the molten head of the ingot.
