several unique functions of slag in iron smelting, the blast furnace and the electric arc furnace (EAF) are presented along with recent research on these subjects. Iron smelting Over the past twenty years a number of direct iron smelting processes have been developed. In these processes, ore and coal are fed directly into a slagmetal bath at about 1500°C and the ore is reduced producing an ...

Air which is heated to about 1200°C is blown into the furnace through nozzles in the lower section. The air causes the coke to burn, producing carbon monoxide which reacts with the iron ore, as well as heat to melt the iron. Finally, the tap hole at the bottom of the furnace is opened and molten iron and slag (impurities) are drained off.
