三角股钢丝绳消除应力及提高质量的方法

Method of triangular strand wire rod stress elimination and quality improvement

介绍三角股钢丝绳生产的基本条件,三角股钢丝绳是在股芯的外面包捻单层或多层钢丝形成截面为三角形的股绳,其工艺参数复杂,所需的工卡具较多,而且捻制钢丝绳时必须采用翻身装置。生产方法:螺旋三角股成绳法、圆股压法。采用工字轮翻身的办法来消除钢丝绳捻制应力,工字轮翻转的方向要视钢丝绳的捻法而定;在后变形器后加定径装置以保证绳径的均匀性和准确性;成品钢丝绳必须要进行预张拉处理,消除钢丝绳捻制应力和结构伸长。根据捻股和捻绳控制要点提出提高捻制质量的方法。

To introduce basic condition of triangular strand wire rope production,triangular strand wire rope is to pack single or multi-layer steel wire on outer of strand core to form strand and rope of triangular cross section,its process parameters are complex,need lots of devices and fixtures,and laying wire rope need to adopt turning over device. Production methods： spiral triangular strand into rope method,round strand pressure method. The wire rope laying stress is eliminated by using spool turning over,direction of spool turning is decided by wire rope laying method. To add sizing device after post-deformation apparatus to guarantee uniformity and precision of rope diameter. Finished rope must be treated with pre-tension process to eliminate wire rope lay stress and structural elongation. According to laying strand and laying rope control key point to put forward improving laying quality methods.
