Abstract
In a segmented water-cooled induction melting crucible mainly used for melting special metals such as reactive metals or alloys, two adjacent segments are coupled as a segment having two legs, one leg having an inlet water passage and the other leg having an outlet water passage, so that these water passages form a one-way water flow path when they are connected. When the two legs are connected at their top portion to form a shorted portion, the lower end of the legs are insulated from each other and from a base forming a bottom of the crucible. Alternatively the two legs can be entirely separated by elongating the slit and the water passage formed in each leg can be connected throgh an insulative, connecting member. In either case, the water pasage in each leg can be reduced to the same size as the inner tube in each segment of a conventional crucible, and by virtue of this construction, both the radial thickness and the width of each segment can be reduced which enables an increase the number of segments in a crucible with the same inner space.
