Modelling Central Consolidation during Hot Rolling of Cast ...

Extending the range of finished product sizes from a given ingot or concast bloom or billet section is often limited by the minimum area reduction required to ensure effective central consolidation and final mechanical properties. Predicting effective consolidation or level of remnant porosity for a range of steel grade, billet size, pass schedule/roll design and thermo-mechanical conditions ...

Finite element modelling of surface defect evolution ...

The hot rolling experiments results reported in (Nioi et al., 2017) were used to validate the model where slabs of 25 mm in thickness were rolled with a rolling radial velocity of 19 RPM (corresponding to a tangential velocity of 0.035 m/sec). A reduction of 40% was achieved in a single rolling pass and roll forces were recorded.

Modelling of Oxide Scale Evolution in Hot Rolling and ...

Oxide scale behaviour in thermomechanical processing has been the subject of intensive research for several years that allowed developing a finite element (FE) based model to simulate a range of events of relevance to the process and the surface quality of the hot rolled product. A range of experimental techniques have also been developed, each providing a partial insight.
