Abstract
An apparatus for the continuous production of steel comprising a generally vertical shaft melting zone having a floor, a generally horizontally running refining zone in fluid communication with a lower region of said vertical shaft, the floor of said refining zone disposed at an inclination with respect to the floor of said shaft, said horizontally running refining zone being in fluid communication with an oxidation zone comprising a well disposed below the level of the floor of said horizontally running refining zone.
