中粗规格制绳钢丝生产工艺方法的研究

STUDY ON TECHNOLOGICAL PROCESS OF MIDDLE DIAMETER ROPE WIRE

在半成品原料→电加热铅淬火→盐酸酸洗→磷化连续处理→ 8/ 6 0 0积线直进式拉丝机拉制作业线和半成品原料→煤气加热铅淬火→间歇式硫酸酸洗→ 5～ 6 / 5 5 0活套式拉丝机拉制作业线上 ,进行了不同工艺因素对制绳钢丝的机械性能影响的实验研究 ,结果表明 :前一作业线 ,明显优于后一作业线 ,生产直径 >2 .0

Experiment on producing middle diameter rope wire with half-finished wire →electric heating patenting→hydrochloric washing→continuous parkerizing process→8/600 deadbeat motobloc drawing process and half-finished wire →gas heating patenting→interrupted sulphuric acid washing→5～6/550 looping motobloc drawing process was done. Influence of variant technological parameter on mechanical character was compared. Results showed that first process was better than second process.
