Abstract (en)
[origin: EP1939305A1] A process for making pig iron in a blast furnace, wherein supersonic oxygen containing gas is injected at the bottom of the furnace and reaches the dead man zone at a velocity which is high enough to substantially avoid the deposition of coal fines in said zone while at the same time the PCl rate may be increased.
