摘要

A mass flow gravity feed furnace charger apparatus includes a charge wellcover (30) having an aperture (33), and an essentiallyvertical conduit (51) for forming a substantially vertically oriented columnof metal chips or scrap within and above the aperture (33), anda structure (SS) for bringing both the charge well cover and conduit intoposition above a charge well (10). The conduit (51) is rapidlymoveable up and down to force metal chips or scrap into molten metal (22) inthe charge well (10) even when the dross level (23A) at thesurface of the molten metal (23) is considerable, so that the apparatus andcorresponding method permit charging when the gravity feedalone is not sufficient or sufficiently rapid.
