On the Theory of Isothermal Hot Rolling of an Aluminum Alloy Strip

Аннотация

The two-dimensional problem of isothermal (including superplasticity conditions) rolling of an aluminum sheet (at a low angle of bite) is analytically solved, and the influence of high homologous temperature on the pressure on rolls is estimated. The energy–force and kinematic parameters of rolling are found using a dynamic model, which adequately describes the experimental data obtained for commercial aluminum alloys. Calculation results are presented for AMg5 and D18T alloys.
