Abstract
The study covers extrusion of preheated aluminum-alloy billets at hydraulic presses within the «heating – metal forming» production complex. Billets are preheated in a multi-section induction heater ensuring a predetermined temperature difference along the billet length. To provide the most favorable conditions for isothermal extrusion, a special task of parametric optimization of the forming process was formulated and solved to a maximum accuracy for the die temperature approaching its maximum permissible value specified by process requirements. The billet state as regards its temperature after loading into the press container was considered as a control parameter at the forming stage. The study used a special alternance method designed to optimize distributed parameter systems. This method is based on mathematical models developed for billet temperature fields at the heating and forming stages.
