SUMMARY:Sniffing out potential of HSS roll material
DESCRIPTION:Materials development for rolling application has become a multi-disciplinary exercise, trying to merge know-how and competence of experts from various fields. ESW follows this path for all developments related to shell material. This paper presents the framework of the current activities in HSS material development for hot strip mills. In this present project, a European HSM, R&D institutions and ESW are working on improving performance and surface capabilities of HSS material. 

Special emphasis is laid on the work in the area of heat treatment. Here, the project goal was to develop a simulation model to identify critical points of time, time savings and to predict alternative heat treatment routes not previously used for HSS compound work rolls.

The simulation was set up in an axisymmetric 2D model in the FEM software Abaqus. For model setup, thermophysical data as well as data from a temperature field measurement were used. The temperature field was recorded by an instrumented work roll containing 12 measuring thermoccouples at different axial and radial positions, during an entire heat treatment. The model was also validated with data from CCT and TTT diagrams as well as dilatometer and residual stress measurements.
