What does a Reverberatory Skimmer do?
Skims slag from surface of copper being refined in reverberatory furnace: Signals OVERHEAD CRANE OPERATOR 921.663-010 to lower pan, and positions it in front of slag tapping hole. Inserts wood pole through door in side of furnace, working pole back and forth to push slag toward front of furnace. Drags slag from surface of copper into pan, using steel hoe. Inserts compressed-air line through furnace opening, and turns valve to force air through molten metal to oxidize impurities. May shovel coke over surface of skimmed metal to prevent excess oxidation.
