The Ingot Plant Roof
Molten metal is tapped into large crucibles and transported
by large forklift trucks from the cell rooms to the plant. In
the plant, the molten metal is either poured directly into 900-
pound ingot molds and allowed to solidify, or it is placed into
furnaces where the metal is alloyed and then cast into either 30-
pound ingots or cylindrical billets. Finally, the finished
metal, whether in ingot or billet form, is prepared for shipment.
