Abstract

A finite element model of hot rolling of steel has been developed. This model takes into account the fundamental non-linearities which characterise the rolling process : inelastic material behaviour, very large deformations and contact between rolls and product. The important points of the model are outlined. The program is used for the development of new roll pass designs and rolling techniques. It allows predictions of the shape of the rolled product at each pass and possible appearance of defects. Expensive industrial trials can thus be avoided. Examples show how the three-dimensional code is applied to groove rolling. A comparison demonstrates excellent agreement between simulation and actual rolling results.
