Annealing After Laser Sintering

Chamber furnace system LH 60/12 with manual lift door and protective gas box for non-flammable protective or reactive gases Chamber furnace LH 30/12

Gas supply system for non-flammable protective or reactive gas with shutoff valve and flow meter with regulator valve, optionally with magnetic valve

The chamber furnace systems LH 15/12 - LH 60/12 have proven themselves for many years as professional chamber furnaces. For stress relief annealing after laser sintering, the furnaces are equipped with a protective gas box for non-flammable protective gas, e.g. argon, and a manual protective gas supply with solenoid valve. The design with gas supply box is a cost-effective alternative to retort furnaces and is suitable for many processes. The batch to be annealed is wrapped in annealing/hardening foil during the process to protect it from oxidation and decarburization. To protect the bottom insulation of the furnace from mechanical stress, a charging plate is required when using a gas supply box.

  • Tmax 1200 °C
  • Recommended operating temperatures up to 1100 °C, at operating temperatures up to 1150 °C increased wear of the protective gas box must be expected
  • Dual shell housing with rear ventilation, provides for low shell temperatures
  • High furnace chamber with five-sided heating for very good temperature uniformity
  • Heating elements on support tubes ensure free heat radiation and a long service life
  • Multi-layered insulation of light refractory bricks and special backup insulation
  • Self-supporting arch for high stability and greatest possible protection against dust
  • Motor driven exhaust air flap
  • Adjustable air inlet in furnace floor
  • Base included
  • Protective gas boxes for inert gas atmosphere with additional thermocouple, type K
  • Solenoid valve, controlled via the extra function of the controller P470
  • Charge control for measuring the temperature directly at the load in the gas supply box
  • Charging plate and annealing and hardening foils
  • Defined application within the constraints of the operating instructions
  • NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive

Chamber furnace system N 7/H with protective gas box Chamber furnace system N 41/H with protective gas box

Protective gas box included in scope of delivery

Chamber furnace systems N 7/H - N 41/H with their low but deep furnace chamber are particularly suitable for smaller batches. The process in these furnaces can be carried out exactly as in the chamber furnace systems LH 15/12 - LH 60/12.

  • Tmax 1150 °C
  • The recommended working temperature is max. 1100 °C. Higher wear and tear of the protective gas box has to be expected at higher working temperatures up to 1150 °C
  • Deep furnace chamber with three-sides heating: from both side walls and 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 chamber furnace system N 41/H and higher
  • Chamber furnace systems N 7/H - N 17/HR are designed as tabletop models
  • Base included with chamber furnace system N 41/H
  • Protective gas boxes for inert gas atmosphere with additional thermocouple, type K
  • Solenoid valve, controlled via the extra function of the controller P470
  • Charge control for measuring the temperature directly at the load in the gas supply box
  • Charging plate and annealing and hardening foils
  • Defined application within the constraints of the operating instructions
  • NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive
