Abstract
The invention relates to a process of melting ferrous metal using a gaseous fuel, a liquid fuel or a pulverized solid fuel in a cokeless horizontal reverberatory furnace (FIG.) consisting of a hearth (), an sloped melting chamber () a vertical refractory grid (), a burner (), a recuperator or regenerator () to transfer heat from waste gas and products of combustion to fresh oxygen bearing gases, whereas a burner system is installed on the hearth for combustion of the fuel and oxygen bearing gas, the hearth under the burner acts as a superheater to achieve the temperature necessary for alloying and to receive the molten metal cascading from the sloped melting chamber, the sloped melting chamber being fed from one end by the rising gas products of combustion and in which the waste gases are subject to post-combustion of carbon monoxide and volatiles before passing through a recuperator or a regenerator to pre-heat the oxygen bearing gases necessary for combustion.
