ESR - Materials

One of the two basic processes of secondary steel purification in conditions of ZTS METALURG, respectively of our new technology from the company CONSARC is defined by a combination of remelting caused by electric arc, actuated by protective atmosphere (argon) and active slag. The result of this process is a secondary homogenized steel with a finer structure, therefore more „plastic“, whereby the process is secured against absorption of alloy, especially hydrogen from air.

Ligatures offer – secondary smelting parts

  • Energetics – steel for production of turbines, high stressed parts in nuclear energetics such as kinetic or pressurized joining elements (STN 16343, AISI 4330, AISI 3205)
  • transport – high stressed circulating bodies of roller bearing with very high resistance against detrition at a combined mechanical stress and resistance against pitting
  • high-speed tool steel and tool steel – production of tools for massive forming at heath – dies for smithing, forging presses, forms for high pressure molding and casting of light and colored metals and plastics (STN 19552, STN 19554, STN 19773)
  • special production – barrel tube
