Ironworks - Wikipedia
After bar iron had been produced in a finery forge or in the forge train of a rolling mill it might undergo further processes in one of the following: A slitting mill - which cut a flat bar into rod iron suitable for making into nails. A tinplate works - where rolling mills made sheets of iron later of steel which were coated with tin.

Iron and steel industry in the United States - Wikipedia
Iron ore coke and flux are fed into the blast furnace and heated. The coke reduces the iron oxide in the ore to metallic iron and the molten mass separates into slag and iron. Some of the iron from the blast furnace is cooled and marketed as pig iron; the rest flows into basic oxygen furnaces where it is converted into steel.

Iron and Steel Slag Statistics and Information
In the production of iron the blast furnace is charged with iron ore fluxing agents usually limestone and dolomite and coke as fuel and the reducing agent. The iron ore is a mixture of iron oxides silica and alumina. From this and the added fluxing agents molten slag and iron are formed.
How Iron Was Made - Saugus Iron Works National Historic Site
The iron then froze into heavy ingots or "pigs". Pig iron was an intermediate step in the making of wrought iron. Pig bars were dragged to the forge using oxen. The slag waste solidified when it cooled and sometimes resembled glass. The slag was disposed of at the waterfront by dumping it over the bulkhead. Over time the slag pile grew.
