Investigation and Computer Design of the Technological Modes of Continuous Rolling of Thin Brass Strips with Specified Accuracy

Resumo

We developed a software system for the numerical analysis and design of the technological modes of continuous rolling of copper and brass strips, which enables us to investigate and design the conditions of deformation required to form specified transverse deviations of the thickness of rolled products. We refined the regularities of the influence of various lubricants and the models of distribution of tangential stresses along the contact arc (according to Coulomb and Zibel) on the pressure, rolling forces, and transverse profiles of the strips of L63 brass. We give recommendations concerning the technological mode and contouring of the rolls in a Tandem-1000 continuous three-stand rolling mill-1000 at the Kirov Nonferrous Metals Processing Plant with an aim to reduce transverse deviations of the thickness of thin strips of L63 brass.
