ABSTRACT:
In a method for producing alloyed steels, wherein in a first manufacturing step iron carriers are to a great extent decarburized and dephosphorized by means of oxygen and after removal of the slag resulting therefrom the melt is adjusted to the desired alloy and carbon content in a further manufacturing step after addition of alloy carriers by means of oxygen and inert gas.
Especially in order to produce stainless steels in an economical manner while achieving a high level of productivity, in particular while charging major amounts of solids,
