Definitions

  • melt metallurgical treatment processes are known in which iron melt is used to take up the impurities.
  • a method of this type is described, for example, in AT 412 283 B.
  • the aim of the process is to form environmentally friendly slags from iron-containing metallurgical residues and to recover the iron content contained therein.
  • the residues in or over an iron melt are reduced by the carbon dissolved in the molten iron.
  • Iron oxide and other metal oxides are reduced and taken up by the molten iron.
  • the resulting metal can be used after dephosphorization as a substitute for a pig iron produced in the blast furnace or at high Cr / Ni contents as a means for stainless steel production.
  • the generated slag can be used as clinker replacement in the cement industry.
  • metallic reducing agent can be added in the form of metallic waste, for example aluminum or iron filings, wherein the proportion of aluminum or iron is preferably at least 80%.
