Bosio, member of the Aichelin Group, announces the successful commissioning of a 72 ft Pit Furnace, a 72 ft Split Type Furnace and a PLC controlled Spray Quenching Unit of the same size for the heat treatment of turbine rotors with a length up to 52 ft and a rotor weight up to 175 tons.


The furnaces are available with gas or electric heating for a temperature up to 2000°F. Different heating zones ensure a temperature uniformity of ± 9°F.


The PLC controlled Spray Quenching Unit can adjust the quench speed by shutting on/off selected zones and switching between the quenching medias water, air or air-water mixture.


For better uniformity the parts can be rotated during quenching. A wireless transmitter ensures real time temperature measurement during the rotation.


For interested customers Bosio can also provide a simulation of the cooling process for their specific application. All plants built by the companies of the Aichelin group ensure a very energy-efficient and environmentally friendly operation with consistently excellent product quality and reproducibility.


These furnace technology is now also available in the US and will be built by the US based Aichelin Heat Treatment Systems Inc., Plymouth, MI. Individual adjustments for every plant enable the development of customized solutions.
