Tempering Furnaces & Applications by Therelek
In the process of heat treatment, a different range of properties can be obtained by controlling the rate of cooling. Parts may be quenched in oil, water, soluble oil solutions, aqueous polymer solutions, inert or nitrocarburizing atmospheres or air.
Quenching and Tempering shall be in accordance and the heating atmosphere shall be neutral to the surface of the steel being treated to prevent decarburization or carburization of the steel surface. Quenching may be direct quenched (cooled to austenitizing temperature prior to quenching) rather than being slow cooled to room temperature and hardened.
Tempering shall occur within 4 hours of the quench. Soaking time shall not be less than 2 hours plus one hour additional for each inch of thickness or fraction thereof greater than 1 inch. Parts may be snap tempered for 2 hours at a temperature that is lower than the tempering temperature.
This process is usually a low-temperature heat treatment which removes stress and fragile through quenching and develop the essential mechanical properties.
Tempering Furnaces by Therelek
Pit Type Low Temperature Furnace
Pit type air circulation furnaces are installed with the opening at ground level or just above it. These are low-temperature furnaces with operating temperatures up to 650°C.
Horizontal Vacuum Furnace
Our Horizontal Vacuum Furnace has cold wall construction with metallic/graphite hot zone. The door swivels sideward and the material is loaded from the front.
Vertical Vacuum Furnace
Therelek’s Bell furnace is designed with optimal performance for high sensitivity and delicate components.
Chamber Furnace
Therelek’s chamber furnace can operate up to 1800°C. These furnaces are usually rugged, refractory based construction
Bogie Hearth Furnace
Our standard bogie hearth furnace goes up to 1500°C, however, we make custom designed furnaces for any special requirements
Continuous Air Circulation Furnace
Continuous air circulation furnace is usually multi-zone controlled for better process control. Individual zones can have preset temperature controls for best process results.
Pyromaitre Ovens
With over 1000 Pyros worldwide, these rapid heating ovens are internationally proven to deliver the highest efficiency when it comes to mass production of tempering/stress relieving of your components
