Text Appearing Before Image:
ed to adapt to copper a processdeveloped in Italy that has been success-fully used for making aluminum rod. The process starts in a large gas furnace,where up to 75 tons of copper scrap aremelted and refined. When ready, the moltencopper is poured in a continuous stream intoan electrically heated holding furnace. Then,at a carefully regulated rate, it flows into agrooved molding wheel and is retained bya rotating steel belt. While in the groove, themoving metal is water-cooled until solidifiedinto a continuous red-hot bar about twoinches thick. Leaving the wheel, the copper is carriedalong a short conveyor and passed through14 closely-aligned steel rollers. In this rollingmill, the bar is further cooled and drawn intorod about one-quarter inch thick. It runs offthe machine and is coiled into large, circu-lar collecting bins. The casting and rollingprocess is controlled from a console by asingle operator. Hot copper rod moves around wheel in newcontinuous casting and rolling operation.
