ABSTRACT:
A method for producing steels within a very close analysis tolerance in which the raw materials are melted down in a first vessel, the melt is then tapped into a second vessel in which deslagging is accomplished, and thereafter the melt is subjected to treatment under a vacuum. An apparatus for carrying out the method is also described.
