1964年以来,鞍钢为了满足国家铁路建设发展的需要,发动职工开展了一炼钢、一初轧、大型等厂“一条龙”的质量攻关运动。同年10月份起,又正式组成了重轨技术工作队,在大搞群众运动的基础上,组织了三结合的科学试验工作。由于全体职工的努力,重轨表面的一级品率迅速提高,1964年4季度已达到95.55%,1965年稳定在97%,超过了苏联库 Since 1964, in order to meet the needs of the development of the national railway construction, Anshan Iron and Steel launched its workers to carry out the quality research and development campaign of “one-stop” steel-making, primary rolling and large-scale plants. In October of the same year, the heavy rail technology task force was formally formed. On the basis of mass mobilization, three scientific experiments were organized. Thanks to the efforts of all staff and workers, the first-class product rate on the heavy rail track has rapidly risen to 95.55% in the fourth quarter of 1964 and to 97% in 1965, surpassing that of the Soviet Union
