This furnace has been specifically designed for melting of loose swarf and light gauge scrap. It is the result of extensive in-house R&D to achieve outstanding parameters in terms of economic throughput and the environment.

Main characteristics:

  • Chips are charged continuously and heated to some 400°C in seconds, whereby hydrocarbons and moisture are evaporated.
  • Thermal reclamation of organic components as dryer and melting furnace are combined into one process.
  • Swarf is introduced directly to the melting process in hot condition, thereby avoiding further oxidation or moisture pick-up.
  • Electromagnetic liquid metal pump for quick, energetic submersion of the charged material and for melt bath movement.

Outstanding achievements:

  • Melting capacity 2 to 5 tons/h or 40 to 100 tons/day
  • Very low specific energy consumption (< 550 kWh/ton including drying) due to LOW-NOx regenerative burner systems, yet very low NOx emissions
  • Extremely low melt loss (< 1 %), thus high metal recovery
  • Low manpower for operation and maintenance
  • Good metal quality of the melt (low oxide and hydrogen content)
  • Meeting most stringent environmental standards
