Abstract:

The study deals with the energy-saving process of hot open die elongation forging of heavy
steel forgings on an 80 MN industrial hydraulic forging press. Three innovative energy-saving power
supply solutions useful for industrial hydraulic forging presses were analyzsed. The energy-saving
power supply of hydraulic forging presses consists in reducing electricity consumption by the electric
motor driving the pumps, reducing the noise emitted by pumps and reducing leaks in hydraulic
piston cylinders. The predicted forging force as a function of heavy steel forging heights for various
deformation temperatures and strain rates was determined. A simulation model of the 80 MN
hydraulic forging press is presented, which is useful for determining the time-varying parameters
during the forging process. An energy-saving control for the hydraulic forging press based on the
forging process parameters’ prediction has been developed. Real-time model predictive control
(MPC) was developed based on multiple inputs multiple outputs (MIMO), and global predictive
control (GPC). The GPC has been implemented in the control system of an 80 MN industrial hydraulic
forging press. The main advantage of this control system is the repeatability of the forging process
and minimization of the size deviation of heavy large steel forgings
