Abstract :

Temper rolling or skin pass rolling is one of cold rolling processes composed of a horizontal pass cold rolling mill stand. In this process, the thick strip is subjected to very light reduction (0.5–4%) in thickness in the presence of high friction amplitudes. One of the basic parameters of strip rolling processes is temper rolling force. A new rolling force model has been proposed for temper rolling strip mill considering the inhomogeneous stress distribution along the thickness of the strip. The contact between rolls and thick strip is totally elastic. The deformation field consists of an elastic (actually elastic) zone and that is highly non-homogeneous across the thickness of the strip. Totally elastic formulation can be used to predict the roll force. It can be used to study the stress distribution along the thickness of strip. The computing results from this model coincide the similar presented results in previous investigations done.
