The melting process and technology are of particular importance in the production of cast iron. The optimum carbon content of the cast iron is ensured by the correct ratio of coke, cast iron scrap and steel scrap. Temperatures of around 1,500 °C are reached in the furnace.

  • Liningless hot blast cupola
  • Holding channel-type furnace (contents 60 t)
  • Two medium frequency induction furnaces (contents 12t each)
  • Magnesium-filled wire treatment for EN-GJS and CGI (compacted graphite iron)
  • Two fully automatic on-site analysis spectrometer
We work with the following material:

  • GJL200 bis GJL350
  • GJV400 & GJV450
  • GJS-400 bis GJS-600

Unique in its size
