Method of forming ingot in process of continuous and semi-continuous casting of metals

Image Number 2 for United States Patent #4014379.

A method of forming an ingot in the process of continuous and semi-continuous casting of metals consisting in that the molten metal is actuated by an electromagnetic field of an inductor, in which case the current flowing through the inductor is controlled depending on the deviations of the dimensions of the liquid zone of the ingot from a prescribed value, and thereafter, the molten metal is cooled down.
