摘要
介绍预张拉电梯钢绳的特殊性能要求，评价现行国标的适用性。根据电梯钢绳拉伸弹性模量（Ｅ值）的测定结果，分析预张拉处理前后钢绳伸长性能的变化，评价ＩＳＯ标准试验Ｅ值的实际含意，提出生产预张拉电梯钢绳应控制的关键工艺环节和可行的新途径。
To introduce the special property requirement of prestretching steel wire rope for elevators,and assess the suitability of GB at presentThe changes of wire rope elongation properties before and after being prestretched are analyzed in terms of the measure results of tensile elastic modulus of wire rope for elevatorsThe implications of testing elastic modulus according to ISO standards are evaluatedThe key process to be controlled and feasible new way while producing prestretching steel wire rope for elevators are put forward
