Abstract
Solid ferrous material, such as scrap and/or sponge iron is melted to produce pig iron in an horizontal or inclined rotary furnace using an oxygen-containing gas and sufficient solid carbonaceous fuel e.g. coal or coke to maintain a continuous cover of fuel over the bath by introducing the oxygen-containing gas above the cover, e.g. by blowing the gas both obliquely against and horizontally over the cover, so that the exhaust gas leaving the furnace contains by volume no more than 10% O2 and has a ratio by volume of CO2:(CO+CO2) of at least 2:3. Slag formers such as limestone may also be added. On tapping the pig iron formed, the fuel cover and preferably the slag with some pig iron may be left in the furnace for a subsequent melting operation, the slag being tapped off before the end thereof. The remaining fuel cover may be burnt with oxygencontaining gas after any melting operation to convert the pig iron to steel. Liquid and/or gaseous fuels may also be used during the melting. The solid ferrous material may also, include prereduced iron ore. After slagging, ferromanganese and ferrosilicon may be added to the steel prior to tapping.
