ABSTRACT:
The disclosure describes a method of direct steel making wherein liquid iron is produced in a melter gasifier system using a solid fuel reductant, preferably petroleum coke, and low silica containing iron ore, preferably less than 2.0% by weight, and the liquid iron is transferred directly to an oxygen blown steel making reactor for steel production and refining.
