Abstract

See full text

Large steel ingot casting is accomplished with a top suspended induction heating device supplied with variable power and variable frequency from a power source. By the induction heating and stirring provided by the top suspended induction heating device, metal solidification advances progressively upwards from bottom to top, and the upper molten metal in a riser part compensates for shrinkage of the lower solidified metal in the main part. Inclusions are selectively moved out of the molten metal by a variable electromagnetic stirring force and the formation of casting defects is suppressed.
