This research involves the development of an efficient
computer code for the thermal/mechanical analysis of
a 26 stand rolling mill. As a rod passes through
the stands, it sequentially changes cross-sectional
shape from round to elliptical and back to round,
etc. - each time reducing its size. The deformations
taking place as the rod passes through a stand are
assumed to be visco-plastic. The thermal analysis
must include the heat generated by the plastic
deformations, the heat transfer to the rolls, the
radiation and convective heat transfer to the
atmosphere between
rolls, including water baths.
