ABSTRACT:
In the particular embodiment of an electron beam cold hearth refining arrangement described in the specification, two separate hearth segments are disposed at right angles to each other and raw material is supplied to a melt area at the end of the first hearth segment remote from the second hearth segment. Molten material is poured from the opposite end of the first hearth segment into the adjacent end of the second hearth segment and refined molten material is poured into a mold from the opposite end of the second hearth segment. To prevent spattering of unrefined material into the mold or the adjacent refining area of the second hearth segment a baffle is positioned in the angle between the two mold segments.
