Cross-wedge rolling (CWR) is a bulk forming process used for preforming, where the billet is traditionally heated homogeneously. Process stability issues, such as slipping or torsion, arise due to varying material flow paths, leading to rolling defects. Inhomogeneous heating (IH) can adjust these flow properties, enhance stability, and reduce defects.
Additionally, it decreases scaling and improves surface quality but remains largely unexplored. This project aims to analyze its impact on the rolling process to optimize quality and stability. The approach involves initial simulations to assess parameter effects, followed by experimental validation.

- Analysis of process stability through temperature control
Design and Tool Development
- Design of a cross-wedge rolling tool for IH-treated billets
- Adaptation of tool geometry to different heating profiles
Measurement & Analysis
- Development of a measurement strategy for automated temperature distribution detection in the billet
- Surface analysis: Evaluation of surface structure for each heating method
- Determination of scaling rate and component accuracy
