Title: Innovations of Axel Von Hehl in Thermomechanical Treatment
Introduction
Axel Von Hehl is a notable inventor based in Essen, Germany. He has made significant contributions to the field of thermomechanical treatment, particularly in the production of seamless steel rings. His innovative methods are particularly relevant for applications in wind turbine generators.
Latest Patents
Axel Von Hehl holds a patent for a "Method for the thermomechanical treatment of seamless rings produced on radial-axial ring rolling machines." This patent describes a method and device for treating seamless steel rings, especially those made from fine grain steel, heat-treatable steel, case hardened steel, or austenitic steel. The process involves inserting a ring blank into a rolling machine at temperatures between 900°C and 1150°C. The rings are then rolled to an outer diameter ranging from 0.2 m to 10 m through a hot forming process. Following this, the hot rings are rapidly cooled without secondary heating, ensuring they drop below 400°C. The device includes a cooling basin filled with liquid and pressure nozzles for targeted cooling.
