    Abstract: A process for producing an ingot from molten metal scrap, particularly scrap consisting of refractory metals such as titanium, zirconium and alloys thereof, comprises changing ungraded metal scrap into a tubular member with a closed end which is made of the same material as that of the metal scrap; melting the scrap-charged tubular member by heating which an electron beam or plasma electron beam, with said member being held substantially horizontally in a vacuum melting furnace. Alternatively, a pair of consumable electrodes which are made of such scrap-charged tubular members are melted with an arc produced between the tips of the tubular members which serve as electrodes. Since the metal scrap need not be graded according to size, the range of scrap charges that can be melted for ingot making is expanded. If the tubular member is replaced by a box with an open top, the scrap can be packed easily and uniformly. This provides improved melting efficiency and a greater ease of melting operations since, in vacuum melting with an electron beam or plasma electron beam, a constant melting rate is attained and, in arc melting using one or more pairs of the scrap-charged boxes as consumable electrodes, a consistent arc can be maintained between the tips of each of the two scrap-charged boxes which serve as electrodes.
