Universal Rolling Mill - Bühler VRW-400

  

The universal rolling mill Bühler VRW-400 allows rolling trials with cold and hot samples. It is possible to perform flat rolling experiments as well as calibre rolling, for the latter several different geometries are available at the institute. Generally, the rolling mill is used for research projects and feasibility studies with different materials. To achieve a deeper understanding of the process, it is possible to perform thermo-mechanically coupled simulations of the process.
