摘要
介绍采用锻打法试制SWAGED4× 39S +FC不旋转钢丝绳的基本情况 ,通过研究国内外四股扇形钢丝绳生产工艺和实物样品 ,确定钢丝绳结构、捻制参数和锻打技术方案。生产实验表明 ,采用ZS捻 ,钢丝绳股、绳捻距倍数分别在 6 .70～ 7.0 0 ,8.4 0～ 9.0 0范围内选取 ,锻打压缩率控制在 10 %左右 ,可生产出强度级别 1770MPa的 13～2 8mm不旋转钢丝绳 。
To introduce basic instance of trial manufacture SWAGED4×39S+FC nor rotating wire rope by means of forging method. The wire rope structure,twisting parameters and forging scheme are confirmed by studying the production process and practicality sample of wire rope with four sector strands at home and abroad. It is indicated by production practice that the nor rotating wire ropes with 1 770 MPa grade and 13～28 mm are manufactured by adopting ZS twisting,selecting the twisting multiples of strands and rope to be from 6.70 to 7.00 and from 8.40 to 9.00 respectively,controlling the compression ratio of forging to be at about 10%, which can meet the technical requirements no matter breaking force or toughness targets of the steel wire of dismantled strand.
