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

Ideal for large charges loaded using a crane

The shaft furnace is used above all for heat treatment of large and heavy charges that are loaded in the furnace by a crane. The furnace is provided with forced air circulation which allows quicker charge heating through and better distribution of thermal field.

Benefits

  • 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
