Open-Hearth Process Essentially the production of steel from pig iron by any process consists of burning out the excess carbon and other impurities present in the iron. One difficulty in the manufacture of steel is its high melting point, about 1370° C (about 2500° F), which prevents the use of ordinary fuels and furnaces.
