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
