一、引言在伟大领袖毛主席“独立自主、自力更生”方针指引下,广大铸造工作者,利用我国富有的稀土资源,一九六○年试制成功具有我国特点的稀土一镁球墨铸铁,为球铁的推广使用,提供了重要条件。经过无产阶级文化大革命的战斗洗礼,球墨铸铁这一新生事物如雨后春笋般地茁壮成长,遍地开花。我厂在筹建过程中,遵循毛主席的伟大教导:“我们必须打破常规,尽量采用先进技术。”为多快好省地发展我国汽车工业,决定我厂生产的6100和6105发动机曲轴采用球墨铸铁。
I. INTRODUCTION Under the guidance of Chairman Mao “great independence and self-reliance”, the majority of foundry workers made use of the rich rare earth resources in our country. In 1960, they succeeded in trial production of rare earth-magnesium-bearing ductile iron with Chinese characteristics, Promote the use of, provided an important condition. After the battle of the proletarian cultural revolution, the new birth of nodular cast iron thrived, thriving, blossom everywhere. I plant in the preparation process, follow Chairman Mao’s great teaching: “We must break the routine, as far as possible the use of advanced technology.” For more rapid and economical development of China’s automobile industry, I decided to plant 6100 and 6105 engine crankshaft with ductile iron .
