摘要
分析国产密封钢丝绳存在的质量问题及其原因 ,通过添加立辊、增加特殊预变形器、采用预张拉技术、改变油质和涂油方式等措施提高密封钢丝绳质量 ,Z型钢丝的内应力降低、表面质量得到很大提高 ,基本消除了钢丝绳的松散现象和因重新调整钢丝绳长度而造成的停产 ,避免了润滑油脂的脱落 ,平均使用寿命提高了 1年以上。
To analyze the quality problem and its cause of locked coil wire ropes made in China . By taking such measures as adding standing roller and special predeformation apparatus,adopting prestretching technology,changing oiliness and grease soaking mode,the quality of the rope improved greatly. The internal stress of Z shaped steel wire reduces and surface quality improves obviously. The loose phenomenon of rope and production stopping due to readjusting the rope length are eliminated,and the shelling of lubrication grease is avoided,the service life of the rope is prolonged more than one year.
