Special Melting & Remelting

 

Vacuum Induction Melting Furnace
Vacuum Induction Melting Furnace

The vacuum induction melting (VIM) process has been established for years as the most important primary vacuum melting technique for today´s industrial production of high performance premium quality special steels and alloys widely used in many extreme and critical applications. VIM produced ingots are often used as electrodes for ESR and/or VAR remelting. As a completion of INTECO’s competence in the special steel shop, a brand new furnace design has been elaborated during the recent years, which enables our customers to produce high end materials in a most modern way.

Variations

  • Single chamber or multi chamber design
  • Casting chamber in mold tunnel or turn table design
  • Heat sizes from lab scale up to 30 t possible
  • Double door design for quick crucible exchange possible

USP‘s of INTECO Design

  • Diagonal split design for melting and casting chamber for best access and safety
  • Short, hot tundish design for reduced risk of nozzle freezing
  • Only vertical vacuum valves for best cleanliness and lowest heat radiation load
  • Tailor made design
  • Level 2 production management system IMAS
  • Reliable, proven power supply and vacuum system

Vacuum Arc Remelting
Vacuum Arc Remelting

The Vacuum Arc Remelting process was the first remelting process to be used for the production of steels and super alloys since the 1950’s. VAR has nowadays reached a very high degree of maturity to satisfy the ever increasing demands on material properties in the field of steel as well as Nickel or Cobalt based materials and reactive metals. INTECO’s VAR plants are especially designed for reliable and safe production in industrial scale as well as lowest maintenance effort.

Variations

  • VAR for steels and superalloys
  • VAR for reactive metals including special safety features
  • From lab scale to 20 t ingot weight and more
  • Multifunctional remelting furnaces (ESR and VAR in one plant)

USP‘s of INTECO Design

  • Coaxial furnace design for improved ingot structure
  • Partial pressure remelting for minimization of evaporation losses
  • Helium cooling system for improved heat transfer between mold wall and ingot
  • Current, melt rate, voltage and drip short control
  • Best access to the melt stations due to the column design
  • Level 2 production management system IMAS
  • Optimized weighing system for accurate furnace control
