BOTTOM CASTING TYPE FLOAT MELTING APPARATUS

PROBLEM TO BE SOLVED: To enable execution of casting in a smaller casting radius than usual, to enable control of the amount of casting with high accuracy in a wide range, while keeping molten metal at high purity, and to enable stop of casting and execution of re-casting. SOLUTION: The frequency of...

Zusammenfassung:	PROBLEM TO BE SOLVED: To enable execution of casting in a smaller casting radius than usual, to enable control of the amount of casting with high accuracy in a wide range, while keeping molten metal at high purity, and to enable stop of casting and execution of re-casting. SOLUTION: The frequency of a current supplied to an induction coil 5 for casting is made a prescribed one in the range of 100 to 500 kHz.
