    Abstract: A melting apparatus having a compact structure, of economical equipment cost, enabling to vacuum melting and refining at high productivity. A metal melting apparatus has a structure in which a refractory furnace wall 12 is furnished on an outer circumference thereof with a seal jacket 16 of air tight and non-electrical conductivity, and disposed with vertical water cooling copper pipes 47 along the inner circumference of the seal jacket 16 at predetermined space, and the furnace casing 10 is arranged at the outer part to encircle the furnace casing with an induction heating coil 38, and the furnace casing 10 is secured to a frame 42 by means of the seal jacket 16 for reinforcing the structure. The seal jacket 16 of the furnace casing 10 is fixed to the frame via an upper flange 44 and a lower flange 28.

    Abstract: The invention provides an improved design for a crucible for the melting of materials by means of radio frequency eddy currents induced in the materials. A segmented platform is located intermediate an open end of the crucible and a closed base at the opposite end, in a region where the crucible wall is segmented, thereby to separate a melt from the ''''cold spot'''' in the crucible caused by the electrical short circuit of the closed base end. The outer surface of the wall segments is curved and defines a single cylindrical surface to facilitate fitting within a primary induction coil.

    Abstract: Method of preparing equipment for holding molten high melting, chemically active metal such as titanium, molybdenum or the like in a crucible or mold, including the prevention of formation of impurities and non-metal inclusion in the molten metal, by providing a receptacle of refractory material as cast, extruded or welded part exhibiting microscopic pores, but providing only insignificant leakage at room temperature; at least a portion of the outer wall surface of the receptacle is lined with a protective layer of copper, chromium, nickel or tin for sealing the pores and for covering at least part of the wall surface of the receptacle with that lining to establish a dense integral pore-free layer that is integral with the sealing of the pores, the lining may also provide corrosion proofing if the receptacle is immersed in a corroding fluid (e.g., potossium or sodium or the like). The receptacle is then filled with the metal and sealingly closed at least when the metal is in the liquid state.
