Calumet & Hecla - Wolverine Tube Division

Metal Trade, Copper Industry and Trade, Manufacturing Process, Manpower, Labor, Skilled Labor Pouring Copper. One of the oil fired furnaces used in the casting of round copper billets. Rigorous control of the temperature of the molten metal is necessary to insure a billet which is sound and free from porosity. The metal is being poured therough a cone known as a runner box, which is guided into place over the center of the mold by the operator at the lower left. The furnace operator at the right is handling a control which tilts the furnace and permits the metal to run into the vertical mold.

Calumet & Hecla - Wolverine Tube Division

Metal Trade, Copper Industry and Trade, Manufacturing Process, Manpower, Labor, Skilled Labor This process shows pouring a series of nine round billets. The man on the right is watching the flow of molten metal through colored goggles and holds a rod in his hand which is used to "feel" the metal as it rises in the mold so he can signal the other operator to bring the furnace back to its melting position and shut off the flow. Previous to casting, phosphorus is added to the molten mass in the furnace to combine with any free oxygen, thus deoxidizing the metal. The furnace charge is then covered with charcoal to protect the metal against further oxidation. Prior to pouring molten metal into a mold, the surface of the mold is coated with a specially developed mold dressing.
