HIGH FREQUENCY ELECTROMAGNET FOR LEVITATING MOLTEN METAL, AND LEVITATING POT PROVIDED WITH THE ELECTROMAGNET

摘要

PROBLEM TO BE SOLVED: To provide a high frequency electromagnet for levitating the molten metal capable of obtaining the necessary electromagnetic levitation force by the minimum power, and a levitating pot provided with the high frequency electromagnet. ;SOLUTION: A pair of magnetic poles 17, 17 opposite to each other across a steel strip carry-in opening part 13 of a high frequency electromagnet 10 comprise parallel surface parts 17a, 17a whose lower parts are opposite to each other with the prescribed intervals therebetween, whose upper parts are continuous to the parallel surface parts 17a, 17a and form tapered surface parts 17b, 17b which are expanded upward, and the line of magnetic force generated between the magnetic poles 17, 17 is smoothly concentrated on the parallel surface parts 17a, 17a.;COPYRIGHT: (C)1999,JPO
