Wire and Strand Annealing Furnaces

Strand annealing furnace D 390/S

D 250/S in production

Wire annealing furnace based on a tube furnace with safety package for hydrogen as process gas

Strand annealing furnaces based on a tube furnace with a length of 6 meters

These models are particularly suitable for continuous heat treatment at operation temperatures up to 1200 °C. The modular design allows adjustment to different length and width requirements. The heating elements are mounted on only one side of the furnace and can be changed individually during operation. Optimum temperature uniformity is achieved by means of a multiple zone control system tailored to the furnace dimensions.

  • Tmax 1200  °C
  • Modular design, variable length
  • Small outer dimensions due to efficient microporous silica insulation
  • Special heating elements that can be changed during operation
  • Heating from the ceiling
  • Optimum temperature uniformity by means of multiple zone control
  • Defined application within the constraints of the operating instructions

Additional equipment

  • Gas supply systems for the working tubes for non-flammable or flammable protective or reaction gases including hydrogen, with burn off torch and safety technology
  • Process and charge documentation
  • Double chamber furnace system with parallel chambers for simultaneous operation at different temperatures
  • Process control and documentation via VCD software package or Nabertherm Control Center (NCC) for monitoring, documentation and control
