沈阳铸造研究所在“九五”期间承担了国家重点科技项目“汽车球墨铸铁件金属型铸造工艺与成套设备的研制”,经过几年的努力,目前已完成了包括水冷温控铸铁型和铜型铸铁件生产成套技术,并建立了中试生产线,其产品(灰铁件、球铁件)已在实际应用中得到验证,标志我国已掌握了该工艺的各项技术。 During the “Ninth Five-year Plan”, Shenyang Foundry Research Institute undertook the research and development of “National Metal Casting Technology and Complete Equipment for Automotive Ductile Iron Castings”, a national key scientific and technological project. After several years of hard work, it has completed a series of projects including water-cooled temperature controlled cast iron and copper Type cast iron production package technology and the establishment of pilot production line, and its products (gray iron, ductile iron pieces) have been verified in practice, marking China has mastered the technology of the process.
