Destination:
The A/SP-1200 unit is intended for spheroidization annealing of forgings made of ŁH15 and ŁH15SG bearing steel. The processes are carried out in a protective atmosphere. Each furnace in the line is electrically connected and controlled automatically during the followoing stage of heat treatment and transfer on transport units.
