  • Open hearth furnace Wikipedia

    The work environment around an open hearth furnace is said to be extremely dangerous, although that may be even more true of the environment around a basic oxygen or electric arc furnace. Basic oxygen steelmaking eventually replaced the open hearth furnace. It rapidly superseded both the Bessemer process and Siemens–Martin process in Western Europe by the 1950s and in Eastern Europe by the .

    liquid steel by blowing oxygen into the molten iron (Basic Oxygen Steelmaking). Along with the liquid iron that was produced in the blast furnace, recycled scrap steel is also added to the oxygen furnace. Pure oxygen is then blasted into the furnace at supersonic speeds via an oxygen lance that is lowered from the top. An oxygen lance is a ...
