Title:
コールドクルーシブル溶解炉
Document Type and Number:
Japanese Patent JP6767652
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a cold crucible melting furnace enabling a state in which an induction current [eddy current] circulating around a tubular cooling water passage in each of the segments to be prevented*restricted, a loss of fed electrical power caused by the induction heating at a crucible to be reduced and a melting efficiency to be increased.SOLUTION: A barrel part 10 of a crucible 1 is constituted in such a way that several segments 2 having a tubular water-cooled passage C1 extending in a height direction formed therein are arranged in a peripheral direction through vertical slits 3 closed by insulation materials 4. As segments 2, at least one wall part of an outer peripheral wall part 22B and two side walls 22C, 22D is formed with a releasing part 24 connected from outsides of the segments 2 to the water-cooled passage C1, and the releasing part 24 is closed with a water-tight material 25 with a higher electric resistivity than that of an inner peripheral wall part 22A to make a cold crucible melting furnace X.SELECTED DRAWING: Figure 2
