Title:
CHANNEL TYPE INDUCTION FURNACE
Document Type and Number:
Japanese Patent JP3921871
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To give an intentional thrust to molten metal in a channel and thereby to make the molten metal in the channel circulate with that in a molten metal chamber, in order to lessen a temperature difference between the molten metal in the channel and that in the molten metal chamber by making the molten metal in a channel part circulate with that in the chamber.
SOLUTION: This channel type induction furnace has a constitution wherein an induction coil 3 is fitted on one side of a core 2 formed by laminating ferromagnetic steel sheets so that they form a quadrilateral and wherein a U-shaped channel 4 is formed of refractory outside the induction coil 3 and an opening part of the channel 4 is made to communicate with a molten metal chamber 6 formed of the refractory. In this case, an electromagnetic thrust for making the molten metal in the channel move in a prescribed direction along the channel is given to the metal by a shifting magnetic field so that the molten metal in the channel may circulate into the molten metal chamber.
