The open hearth furnace could be used either with phosphoric or non-phosphoric iron, by applying basic or acid lining. An open hearth plant is preserved at Munkfors, where a regenerative furnace was first used to make steel in 1864.
Tariffs were the greatest (approaching 95% at times) source of federal revenue until the federal income tax began after 1913. For well over a century the federal government was largely financed by tariffs averaging about 20% on foreign imports. At the end of the American Civil War in 1865 about 63% of Federal income was generated by the excise taxes, which exceeded the 25.4% generated by tariffs.

Ladle Refining Furnace Large ladles are used in most metal-melting operations to transfer molten metal from melting furnaces to refining or pouring stations. The LRF also acts as a buffer between the steel making furnace and the continuous caster, reducing casting costs and allowing greater flexibility in steel making operations.
