从技术标准、用户习惯、原辅材料、拉丝设备、质量控制等角度出发,就6×7大直径钢绳生产难的原因进行了分析,提出选用70mm以上粗直径优质盘条,采用盘条—预拉拔—热处理—成品拉制的工艺流程,使用先进的活套式或直线式拉丝机和优质润滑剂,成品拉制用总压缩率小、多道次工艺路线,可显著提高6×7大直径钢绳的质量。
From the technical standards, user habits, raw and auxiliary materials, drawing equipment, quality control and other aspects of the reasons for the difficult production of 6 × 7 large diameter steel wire rope was analyzed, the selection of more than 7 0mm thick diameter of high quality wire rod, disk - pre-drawing - heat treatment - drawing the process of finished products, the use of advanced live-loop or straight wire drawing machine and high-quality lubricants, finished drawing with the total compression rate of small, multi-pass process can significantly improve the 6 × 7 The quality of large diameter steel rope.
