今年3月份,机械工业部机械工业技术交易中心和机械工业部北京机床研究所在四川灌县宁江机床厂举行了高强度低应力铸铁技术转让讲习班。学员来自机械、轻工、冶金、军工等单位。专家和学者分别讲授了国内外高强度低应力铸铁的研究与应用情况;高硅碳比铸铁的低应力、高韧性、小变形的研究;铸铁应力松驰性能及其测量方法和装置的研 In March this year, the Machinery Industry Technology Exchange Center of the Ministry of Machinery Industry and the Beijing Machine Tool Research Institute of the Ministry of Machinery Industry held a workshop on the technology transfer of high-strength and low-stress cast iron at the Ningjiang Machine Tool Plant, Guan County, Sichuan. Students from machinery, light industry, metallurgy, military and other units. Experts and scholars respectively teach the research and application of high-strength low-stress cast iron at home and abroad; research on low-stress, high-toughness and small deformation of high-silicon-carbon cast iron; research on stress relaxation of cast iron and its measuring methods and devices
