Abstract
The present invention relates to a process for treating liquid steel for the manufacture of machine wire. All or part of the manganese is added to an extra-mild steel, obtained after refining by any steelmaking process, directly in the production apparatus to obtain the desired manganese content. The steel thus obtained is poured into a first ladle or into another pouring apparatus and carbon is added to the liquid mass in the first ladle and thereafter the metal obtained is poured into a second ladle and a given amount of, first, silicon and then aluminium is added. This process produces a machine wire which is more suitable for wiredrawing.
