For outputs of 1000 to 5000 Kg/hr

Large electric furnaces/ovens are available in standard and customized configurations, to ensure these are designed with the durability and efficiency required to meet higher yield requirements for superior performance for your parts. These are available for a wide range of applications where processing within 540°C is required, including for tempering and stress relieving. Even though for a Pyro these are large, these rapid electric continuous stress relieving furnace is conventionally compact!

Special Applications – Tempering of Induction Hardened Parts, Tempering of Crankshafts



Pyro first designed ovens for springs. The first high-speed oven was designed for a spring manufacturer, and all the future models were based around this application. While most spring makers struggle with CrSi applications, our customers are able to stress relief torsion springs of tight tolerances in minutes. A 6mm wire CrSi can be completely stress relieved in 3 minutes in a Pyro oven while maintaining the precision obtained by the coiler. With a Pyromaitre oven, suspension-spring makers stress relieve 13mm in 6 minutes. This is also applicable for other materials.
