Youngstown Sheet and Tube Company's Campbell Works cast house

An interior view of the cast house at the Youngstown Sheet and Tube Company's Campbell Works, East Youngstown (Campbell), Ohio, ca. 1910-1919. Inside of the casting house is where the blast furnace was tapped. From the blast furnace the liquid metal flowed into two trenches: one for the iron to the right, and one for the slag to the left. Each flowed in a different direction to the series of gates that sent the metal to the waiting iron ladles and slag buckets
