Chamber Furnaces for Annealing after Laser Sintering

N 41/H N 7/H with protective gas box
N 7/H - N 41/H

For the annealing of frameworks made of cobalt-chromium after laser sintering the chamber furnaces N 7/H - N 41/H are used. These furnaces will be equipped with a gax-box as well as an automatic gas-supply system for one non-flammable protective gas, e.g. Argon. Please ask for our catalog “Thermal Process Technology”.

  • Tmax 1150 °C
  • The recommended working temperature is max. 1100 °C. Higher wear and tear of the gassing box has to be expected at higher working temperatures up to 1150 °C
  • Three-sided heating from both sides and the bottom
  • Heating elements on support tubes ensure free heat radiation and a long service life
  • Bottom heating protected by heat-resistant SiC plate
  • Multi-layer insulation with high-quality lightweight refractory bricks in the furnace chamber
  • Exhaust opening in the side of the furnace, or on back wall of furnace in the N 41/H models and higher
  • Models N 7/H - N 17/HR are designed as tabletop models
  • Base included with model N 41/H
  • Parallel swinging door which opens downward, or upward upon request
  • Protective gas boxes for inert gas atmosphere with additional thermocouple, type K
  • Solenoid valve, controlled via the extra function of the controller B400
  • Digital temperature indicator for measuring the temperature inside the gassing box
  • Charging plate and annealing and hardening foils
  • NTLog for Nabertherm Controller: Recording of process data with USB-flash drive
  • Defined application within the constraints of the operating instructions
