Description
Description of the photograph reads, “Tapping a heat of steel from the open hearth furnace, another method of converting iron into steel.” Open hearth furnaces (pictured here) were used extensively in the manufacture of steel in many of the steel mills in western Pennsylvania. Molten iron is poured into a large shallow hearth and subjected to intense heat, which removed impurities from the iron and subsequently prepared it for the infusion of other elements. After tapping from this furnace, the steel was ready to be poured into ingot molds.
