Résumé

Industrial production lines for forgings have been set up to maintain a high level of performance and to guarantee good product reliability. The processing and treatment cycles concerned involve an important energy commitment. The aim of our research was to reexamine the feasibility of more sensible energy balances, which, while maintaining the characteristics of the forgings, aim to reduce the consumption of the amounts of material and of energy needed for each stage of production. Our research is therefore directed towards eliminating or reducing certain stages of production without affecting the characteristics of the forging. The following two principal methods have been studied: a) The elimination of rolling by forging from cast bars. b) The reduction or elimination of heat treatment after forging. Three types of new treatment cover all the types of forging we produce: direct isothermal tempering direct classical tempering direct tempering in water or oil.
