By using protective gas boxes, annealing furnaces, forced convection furnaces and pit-type furnaces can be upgraded for heat treatment processes under non-flammable protective and reactive gases.

Annealing Boxes
Annealing boxes are filled with powder or granules into which the charge is placed. Processes like soldering can be carried out in an inexpensive manner.

Complete Workshop Hardening Systems
The Nabertherm compact hardening systems consist of a hardening furnace, a tempering furnace, a quenching and cleaning bath. They can be used for various heat treatment processes in the workshop.

Quenching and Cleaning Baths 
Baths for quenching in oil or water as well as for cleaning and degreasing are available as single or double baths and are made of stainless steel.

Auxiliary Materials for Better Charge Results 
Hardening foils, annealing bags, granulate

Protective Equipment 
Gloves, face and body protection

]]> Chamber Furnaces for Annealing, Hardening and Brazing up to 1280 °C https://www.labsupply.co.za/shop/furnaces/chamber-furnaces/chamber-furnaces-for-annealing-hardening-and-brazing-up-to-1280-c/ Thu, 15 Feb 2024 13:13:13 +0000 https://www.labsupply.co.za/?post_type=product&p=19139 To withstand harsh use in the laboratory, e.g. when heat-treating metals, robust insulation with light refractory bricks is necessary. The chamber furnaces N 7/H - N 87/H are a perfect fit to solve this problem. The furnaces can be extended with a variety of accessories, like annealing boxes for operation under protective gas, roller guides, or a cooling station with a quench tank. Even high-performance applications like the annealing of titanium in medical applications can be implemented without the use of expensive and complicated annealing systems.

Standard Equipment

  • Tmax 1280 °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
  • Temperature uniformity up to +/− 10 °C according to DIN 17052-1
  • Low energy consumption due to multi-layer insulation
  • Base frame included in the delivery, N 7/H - N 17/HR designed as table-top model
  • Parallel guided downward swinging door (user protected from heat radiation)
  • Door movement cushioned with gas dampers/struts
  • Controller B500 (5 prgrams with each 4 segments)
  • Defined application within the constraints of the operating instructions
  • NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive
