遵照毛主席关于“独立自主、自力更生”的伟大教导,我们发扬了敢想、敢干、敢革命的精神,从六五年起,开始以稀土-镁球墨铸铁代替过去用钢材制造压缩机曲轴、连杆和十字头的研究工作。经过几年的反复实践,我们取得了初步的经验。目前,我厂的所有中、小型压缩机曲轴、连杆和十字头均采用球墨铸铁,为国家节约大量的钢材,仅一九七○年,就给国家节约优质钢材350吨。
In accordance with Chairman Mao’s great teaching on “independence, self-reliance,” we carry forward the spirit of dare to think, dare to do and dare to revolutionize. From 65 onwards, we started to use rare earth-magnesium nodular cast iron instead of the steel crankshaft used in the past to manufacture compressors Rod and crosshead research work. After several years of repeated practice, we have achieved initial experience. At present, all the small and medium-sized compressor crankshafts, connecting rods and crossheads are made of ductile iron, saving a lot of steel for the country, only in 1970, gave the country to save 350 tons of high-quality steel.
