6150小六角工具钢丝生产工艺探讨

介绍6150小六角工具钢丝的化学成分、产品特性及用途。传统的6150小六角工具钢丝生产存在的问题:设备产能低,钢丝盘重小,效率低;采用石灰涂层预处理工艺不利于拉拔;再结晶退火温度高、能耗大,使产品硬度低。针对这些问题,对原料规格、酸洗参数、拉丝模具锥度进行优选,采用机械剥皮、保护罩式炉低温退火、磷化、连续拉拔设备和工艺,减少了生产周期,生产的钢丝光亮、无脱碳现象。

Probe into production process of 6150 type small hexagonal tool steel wire

To introduce the chemical composition,product characteristic and usage of 6150 type small hexagonal tool steel wire.The problems existing in conventional production of 6150 type small hexagonal tool steel wire are : equipment has low production capability,light steel wire coil and low efficiency;pre-treatment process adopting milk of lime coating goes against drawing;re-crystallizing anneal is at high temperature,energy consumption large,and make product have low hardness.Aiming at the problems to optimize ...
