Abstract:
    A process for the production of pig iron from iron ore is disclosed. The pig iron is firstly converted to sponge iron in a direct reduction shaft furnace (1) and then the sponge iron is converted to pig iron in a melt-down gasifier. The melt-down gasifier is supplied with a carbon carrier in the form of coke and oxygen-containing gas. With the aid of a screen, the melt-down gasifier is supplied with the fine fraction via pipe and the shaft furnace is supplied via pipe with the coarse fraction of the coke required for the operation of the plant. The coke introduced into the shaft furnace passes through the same and then enters the melt-down gasifier in preheated, dried form. The coke in the shaft furnace also leads to a reduction of CO2 and H2O to CO and H2 and also reduces the sticking tendency of the sponge iron.
