: A view of the cast house tapping machine at the Youngstown Sheet and Tube Company's Campbell Works, East Youngstown (Campbell), Ohio, ca. 1910-1919. The tapping gun opens a hole and allows the molten iron to flow from the blast furnace. The opening is kept sealed by clay until the furnace is ready for tapping. The clay is then drilled out of the tap hole until the iron skull is met. Next, the iron skull is burned through with an oxygen lance. Then the liquid iron is allowed to flow out of the furnace. The tapping machine is moved by a crane that attaches to the gun. View on Ohio Memory.
