Aichelin Group, Austria, announces that member company Bosio, Slovenia, has commissioned a 72-foot pit furnace, a 72-foot 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 feet and a rotor weight up to 175 tons. The furnaces are available with gas or electric heating for temperatures 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 a 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.
This furnace technology is now also available in the United States, and will be built by the U.S.-based Aichelin Heat Treatment Systems Inc., Plymouth, Mich.
