The purpose of the present invention is to provide an energy-saving-operation recommending system that can calculate the energy consumption predicted to be consumed by the entire body of a rolling line, with high accuracy and with respect to a material to be rolled that is scheduled to be rolled next. The total energy consumption consumed by plurality of equipment during a step in which one material to be rolled is passed through the rolling line is calculated. The total energy consumption is divided by the width and the length of the material to be rolled prior to rolling, and energy consumption reference values, which define the energy consumption per width unit and length unit of the material to be rolled, are calculated. The energy consumption reference values are associated with the steel grade of the material to be rolled and the target post-rolling plate thickness, and stored. An energy consumption reference value that corresponds to the steel grade and target post-rolling plate thickness of the material to be rolled, which is scheduled to be rolled next on the rolling line, is acquired. The width and the length of the material to be rolled that is scheduled for rolling is multiplied by the energy consumption reference value, and an energy consumption prediction is calculated. |
