摘要： A method of refining metal to be processed to a high degree of purity by heat-melting the metal in a melting furnace in the form of a metal crucible placed in a vacuum vessel. The method includes evacuating prior to melting, preheating the inside of the entire vacuum atmosphere including the inner wall surface of the vacuum vessel, component parts inside the vessel and the like in order to keep the total pressure within the vessel at 1.times.10.sup.-8 Torr or lower, and effecting high frequency induction heating while controlling the partial pressure of each of O.sub.2, H.sub.2, CO in the atmosphere inside the vessel. Further, the vacuum vessel, the metal crucible and an induction heating coil attached to the crucible, each of which has double jacket structure, are heated or cooled by supplying circulating heating or cooling water in a water-passage space of each of the vacuum vessel, the metal crucible and the induction heating coil, so that the inside of the melting furnace is baked.

摘要： 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.
摘要翻译：在主要用于熔化诸如反应性金属或合金的特殊金属的分段水冷感应熔炼坩埚中，两个相邻的段联接为具有两个腿的段，一个腿具有入口水通道，另一个腿具有出口水通道使得这些水通道在连接时形成单向水流路径。当两个腿在其顶部连接以形成短路部分时，腿部的下端彼此绝缘并形成坩埚底部的底座。或者，两条腿可以通过延长狭缝而完全分开，并且每条腿中形成的水通道可以连接在绝缘的连接构件上。在任一情况下，每个腿中的水管可以缩小成与常规坩埚的每个区段中的内管相同的尺寸，并且由于这种结构，可以减小每个区段的径向厚度和宽度，能够增加具有相同内部空间的坩埚中的段的数量。
