An electron beam cold hearth refining furnace includes two separate hearth segments (30, 33) disposed at right angles to each other. Raw material (14) e.g. titanium, is supplied to a melt area (17) at the end of the first hearth segment (30) remote from the second hearth segment (33). Molten materia...

description	An electron beam cold hearth refining furnace includes two separate hearth segments (30, 33) disposed at right angles to each other. Raw material (14) e.g. titanium, is supplied to a melt area (17) at the end of the first hearth segment (30) remote from the second hearth segment (33). Molten material (34) is poured from the opposite end of the first hearth segment (30) into the adjacent end of the second hearth segment (33) and refined molten material (37) is poured into a mould (38) from the opposite end of the second hearth segment (33). To prevent spattering of unrefined material into the mould (38), and also possibly an adjacent refining area (35) of the second hearth segment (33), a baffle or shield (39) is positioned in the right angle between the two hearth segments (30, 33) to be laterally spaced therefrom. Pouring of melt from the first to the second segment at a lower level than the first, creates additional stirring to aid refining.
