现代内燃机要求其关键基础件在持久的工作期限内具有高度的可靠性。在关键基础件中,没有其它零件比活塞(尤其在头部和销座部)受到更恶劣的工作条件。液态模锻铝活塞因其兼备了锻造活塞和重力铸造活塞的许多优点,可以适用现代内燃机的发展。因此,多年来受到人们的关注。本文结合我厂所进行的液态模锻铝活塞的工艺试验,就其工艺特点和经济效益等提出我们的看法。
Modern internal combustion engines require that their critical foundations have a high degree of reliability over a long working life. Among the key foundations, no other part is subjected to worse working conditions than the piston, especially on the head and pin. Liquid forged aluminum piston because it has both the advantages of forged piston and gravity casting piston can be applied to the development of modern internal combustion engines. Therefore, people’s attention has been received for many years. In this paper, I conducted a liquid-forged aluminum piston process tests carried out on its technical characteristics and economic benefits put forward our views.
