高速柴油机内油路活塞的铸锻工艺是一项新工艺。据了解,国内尚未搞过,国外这种活塞也用得不多。为适应高速柴油机生产的需要,我们坚持“独立自主、自力更生”的方针,在技术资料缺乏和设备条件差的情况下,又遵照毛主席关于“下定决心,不怕牺牲,排除万难,去争取胜利”的伟大教导,在不长的时间内,终于初步试制成功了铸锻活塞。 Casting and forging process of oil piston in high speed diesel engine is a new process. It is understood that China has not engaged in this type of piston abroad is also limited. In order to meet the needs of high-speed diesel engine production, we adhere to the principle of “independence, self-reliance and self-reliance”. In the absence of technical information and poor equipment conditions, we follow Chairman Mao’s principle of “resolving without fear of sacrifice, eliminating all difficulties and winning victories” Great teaching, in a short time, finally succeeded in trial production of casting and forging piston.
