Heat Treatment

Heat treatment is performed in gas and electric furnaces. The furnaces are lined with fireclay lining, or fiber material lining. The process is controlled by PC and documented by heat treatment data logging.

Main types of heat treatment:

Annealing: normalizing, soft annealing, stress relief annealing, stabilization annealing, dissolvent annealing, sferoidization annealing
Refining of carbon and alloyed steels
Controlled carbon potential cementation
Hardening of tooling steels up to the austenitization temperature of 1 200 °C
Hardening of special and ledeburitic steels
Hardening in the atmospheres
Tempering in a salt bath

Production parameters

height = 1 600 mm
Max. internal dimensions of cementation furnaces: diameter = 750 mm
height = 1 300 mm
Maximum sizes of cooling bath
Max. internal dimensions of the water bath: width = 2 900 mm
length = 9 000 mm
depth = 6 000 mm
