Project duration 01.02.2020 – 31.01.2022
Press release

In order to automatically determine the state of an aluminum melting furnace, the IPH develops a Preforms that can be produced by cross wedge rolling are further processed in the forging industry into a wide variety of components and are characterized by high material efficiency. The aim of the project is to identify a process window for a cross wedge rolling process by which an ultrafine microstructure can be adjusted in cylindrical blanks. The desired grain size of the rolled part should be in the ultrafine grain range. A cross wedge rolling process for mass distribution can also be connected to the cross wedge rolling process for the production of ultra-fine microstructure in order to make use of the good properties (high ductility, good formability at low temperatures) of the preforms with simultaneous material-efficient further processing.
