The open-hearth furnace (OHF) uses the heat of combustion of gaseous or liquid fuels to convert a charge of scrap and liquid blast-furnace iron to liquid steel.
The basic oxygen steel-making process is as follows: Molten pig iron (sometimes referred to as "hot metal") from a blast furnace is poured into a large

Open hearth furnaces remove impurities from molten iron, scrap steel and limestone when charged in the furnace. Heat for the furnace is supplied by blowing
