我厂与重庆大学机械二系合作于1980年初在我厂进行了稀土球铁钢锭模的试制与研究工作,同年七月二十二日在厂内通过鉴定,1981年五月获四川省重大科技成果三等奖,1982年正式转产,1983年稀土球铁钢锭模获冶金部优质产品称号。所研制的稀土球铁钢锭模与原用的普通灰铸铁钢锭模相比较,具有较高的常温高温强度,较优良的抗生长、抗热疲劳性能等优
I plant and Chongqing University Department of Mechanical second-line cooperation in early 1980 in our factory for rare earth-iron ingot mold trial and research work, the same year in July 22 passed the appraisal in the factory, in May 1981 by the major science and technology in Sichuan Province Third prize achievement, formally converted in 1982, 1983 rare earth iron ingot mold Metallurgical Department of the title of quality products. The developed rare earth ductile iron ingot mold with the original ordinary gray cast iron ingot mold compared with higher room temperature and high temperature strength, excellent resistance to growth, excellent thermal fatigue resistance
