ABSTRACT:
In a steel making process with an oxygen top-blown converter when a certain inclining angle (.theta.) is given within a range of 0<.theta..ltoreq.15.degree. to normal axis of an oxygen blow lance being supported at an upper portion of the lance and a certain number of rotation (.nu.) is given within the range of 0<.nu..ltoreq.15 rpm to the lance, the blow of oxygen is possible to be properly used as the refining reactions are advanced without any delay of slagging reaction and any stagnation of non-slagging lime during blowing.
