按照钢丝绳的使用要求,钢绳内不应存在残余应力,以利于钢绳的承载能力及其使用寿命,因此对钢绳的不松散要求是相当重要的。在我国的一些文献中都进行了类似的试验和分析,都证明了消除残余应力会使钢绳寿命提高30～50%乃至几倍之多,而且还可以使钢绳变得更为柔软。因此我国钢绳国家标准GB1102—74中明确规定:“所有钢绳应制造成 In accordance with the requirements of the use of wire rope, there should be no residual stress in the steel wire rope in order to facilitate the carrying capacity of steel wire rope and its service life, so the rope is not loose requirements is very important. Similar tests and analyzes have been carried out in some of our country’s literature, both proving that the elimination of residual stresses can increase rope life by 30 to 50% or even a few times and also make the rope softer. Therefore, our national standard steel wire GB1102-74 clearly states: ”All steel should be made into
