摘　　要：介绍了我国ADI生产技术的新进展,主要表现在:(1)CADI磨球取得较大进展;(2)重型卡车底盘零件有可能成为我国ADI产量新的增长点;(3)ADI(CADI)在抗磨耐磨零件上应用取得突破;(4)等温淬火热处理中心的建立,使质量稳定、价格合理的热处理装备又重新成为大家关注的问题;(5)生产球墨铸铁原辅材料质量的改善以及球墨铸铁毛坯质量的提高,为齿轮、曲轴等零件重新采用ADI增强信心。同时,提出了目前ADI生产过程中存在着产品稳定性和一致性差的问题以及今后的发展方向。An introduction was conducted to the new progress of ADI production technology in China,the main progresses were as follows：（1）CADI grinding balls production technology had relatively obvious progress.（2）It was possible that the chassis parts of heavy trucks would become the new growth point of ADI production in China.（3）The application of ADI（CADI）to abrasion-resistant and anti-abrasion parts has got breakthrough.（4）The establishment of isothermally-quenching center caused the heat treating equipments with stable quality and rational price to become the problem attracting public attentions.（5）Quality improvement of raw and accessorial materials used for ductile iron production and quality elevation of rough ductile iron castings strengthened confidence to re-use ADI for making important parts such as gears,crankshafts et al.In addition,the problem of poor quality stability and consistency of products existing in the ADI production process,as well as the future development direction of ADI were proposed.
