Abstract

PURPOSE: To accomplish pre-refining with a low decarburization suitable for converter refining with the temperature of molten iron retained at a low level through blowing of a given amount of oxygen with a proper agitation, for example, by bubbling of inert gas, after a given dephosphorizing agent is added.
