1.前言自1973年石油危机以来,在高温及热能使用多的部门,节能活动开展得特别活跃。在汽车工业中,紧紧抓住汽车使用和制造这两个阶段,积极开展节能活动,并取得了良好的效果。汽车上所使用的锻件,约占汽车自身质量的15%。由于锻件的强度和可靠性较好,故多用于重要功能部位。锻件热处理的节能活动,必须在充分保证质量的前提下进行。 1. Introduction Since the oil crisis in 1973, energy-saving activities have been particularly active in sectors with high heat and thermal energy usage. In the automotive industry, we are firmly engaged in the two stages of vehicle use and manufacturing and are actively implementing energy conservation activities with good results. Forgings used on the car, accounting for about 15% of the quality of the car itself. Due to the strength and reliability of forgings is better, it is mostly used for important functional parts. Forgings heat treatment of energy-saving activities, must be fully guaranteed quality under the premise.
