Flux for steelmaking in converter

Currently, the steel plants need to increase the service life of the lining of converters during the slag blowing by nitrogen. For this purpose complex magnesia fluxes based on dolomite and magnesite are used.

High-Mg flux FluMag is used for the infliction of high-strength slag skull on the converter lining, as well as for increasing of the durability of the scull coating during steelmaking in process of blowing of slag by nitrogen and for adding in filling scrap.

Acting mechanism of action of high-Mg flux FluMag

Application of the slag skull on converter lining

  1. Adding of magnesia flux FluMag to the remaining slag after discharging of metal from converter
  2. Slag saturation by magnesium oxide with forming of periclase phases (MgO); magneziowustite (MgO x FeO); magnesioferrite (MgOхFe2O3)
  3. Drawing of the slag skull on converter lining by high-pressure nitrogen

Increasing of resistance of the coating on the ledge of the converter lining

  1. Adding FluMag flux on piled scrap metal in the converter.
  2. Roasting of flux by pour iron (t = 1300 — 1400 °C) with forming of periclase (MgO) in thicker of scrap and removing of H2 into the atmosphere.
