Abstract

The paper introduces the results obtained in the determination of the variation domains of the technological parameters used for steel secondary treatment in LF-type installations, in view of improving its quality. The use of the resulting technological parameters allows the production of low-gas steel (particularly low-hydrogen) and brings new information pertaining to steel degassing in the steel secondary treatment installations.
