Possible rolling forces range for P1500 rolling mill (Twin Steckel) conditions

Software solution is based on mathematical optimization methods when the following two types of algorithms are applied:

  • »pass schedule optimization including bending forces optimization
  • pass schedule optimization and additional bending forces optimization
