Abstract
The paper observes the process of ladle vacuum refining (VDF/VDOF) based on the principle of localization of volume of degassing metal via usage of reaction chamber with separation of vacuum chamber space in two areas with different depression degree. It allows to exclude metal overflow outside ladle side and to increase mass of vacuumized melt. The project of modernization of vacuum vessel operating in the converter shop of “Severstal” metallurgical works, with putting into practice of VOD/VOFD unit is developed.
keywords Steel, ladle vacuum treatment, refining, pressure, reaction chamber, gas-slag-metallic emulsion, argon.
