粉末冶金技术是在1909年用钨粉制造钨丝开始的。国外近二、三十年来发展很快。我国是1958年开始研制和生产粉末冶金制品的。十几年来,在毛主席无产阶级革命路线指引下,由于广大革命职工的努力,取得了很大的成绩。1965年铁基粉末冶金制品的产量为735吨,1971年达到7000吨,六年增长了将近10倍。目前我国粉末冶金制品已广泛地应用在汽车、机床、农机、工程机械、矿山机械、机车车辆、仪器仪表、轻工机械等各个工业部门。采用粉末冶金的技术经济性是十分显著的。例起,1971年上海粉末冶金厂生产了250种、
Powder metallurgy started with tungsten powder in 1909. Nearly two or three decades abroad developed rapidly. Our country started to develop and produce powder metallurgy products in 1958. Over the past decade and more, under the guidance of Chairman Mao’s proletarian revolutionary line, great achievements have been made thanks to the efforts of the vast revolutionary workers. In 1965, the output of iron-based powder metallurgy products was 735 tons, reaching 7,000 tons in 1971, an increase of nearly 10 times in six years. At present, China’s powder metallurgy products have been widely used in various industrial sectors such as automobiles, machine tools, agricultural machinery, construction machinery, mining machinery, rolling stock, instrumentation, light industry machinery. Technical and economical use of powder metallurgy is very significant. For example, Shanghai Powder Metallurgy Factory produced 250 kinds in 1971,
