Abstract：

In order to achieve energy efficiency goals for forging industry, firstly, the characteristics of forging billet were analyzed, then according to specifications of forging billet heating, a forging billet charging scheduling model with an objective function, which was capacity residuals of charging, was established considering influences of the shape and size of the forging billet on heating time. Then, based on genetic algorithm, an algorithm for objective function was constructed by genetic algorithm binary coding and elite reserved strategy. At the same time, the forging billet charging energy-saving scheduling model and its effectiveness and feasibility were verified by the relevant examples. Finally, by analyzing application examples, the amount of work time of each furnace is reduced 11 min,14 min,18 min and 15 min respectively, so the power of 1174.5 GJ is reduced for each batch of forging billet. Thus, it is proved that the energy-efficient scheduling model and solving methods meet the needs of field charging. Under the certain production conditions, the furnace utilization is effectively improved, furnace working period is shortened, and the goal of energy saving is achieved. At last, it helps to save energy in the forging process.
