SC shaft furnace with internal atmosphere circulation up to 850 °C

Ideal for large charges loaded using a crane

We have designed this shaft furnace to make it serve well for heat treatment of charges that are large enough and heavy enough to need loading by crane. For charges like these, it is very important for heat to be conducted into them as well as possible, so that heating is as efficient as possible. Because of this, we have equipped these furnaces with forced air circulation.

  • The heating placed along the walls ensures an even temperature distribution in the chamber’s internal operational space
  • Forced air circulation
  • A refractory steel grate is located at the bottom of the furnace; it is used for loading the charge, and meanwhile enables air circulation within the furnace

Charge treatment technology

  • Soft annealing
  • Annealing for stress relieving
  • Recrystallisation annealing
  • Artificial ageing
  • Low-temperature tempering
  • High-temperature tempering
  • Curing
  • Tempering of tool steels with protective atmosphere (in semi-gastight variant)
