Chamber furnaces are usually rugged, refractory based construction or lightweight ceramic fiber board and insulation based in construction.
Heating elements could be Nichrome, FeCrAl, silicon carbide or molybdenum disilicide depending on the temperature and process.These furnaces can be used for hardening, annealing, normalizing, sintering, tempering, stress relieving, pre-heating etc. The entire range, size and temperature can be determined by individual need and requirement. The door design can be Hinge Type or Vertical Lifting as per chamber size.
