Title:
METHOD AND DEVICE FOR PRODUCING MOLTEN METAL
Document Type and Number:
Japanese Patent JP2017228393
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a technique capable of increasing the total amount of heat of heating while avoiding damage, in heating metal by two kinds of heating methods of resistance heating and induction heating.SOLUTION: After metal in a solid state is disposed, the supply of AC power to a coil assembly is started at an initial supply amount to heat the metal. On this occasion, if a deviation amount based on a difference between a phase difference of a phase of AC current with respect to a phase of AC voltage in a state where molten metal does not exist and a phase difference of a phase of AC current with respect to a phase of AC voltage at the present moment is larger than a predetermined reference value, the supply amount of the AC power is increased.SELECTED DRAWING: Figure 2
