制钉用不锈钢丝的生产

Production of Stainless Steel Wire for Nail Making

用ＳＵＳ３０４生产出１７５～４０ｍｍ不锈钢丝，再制成麻花钉。钢丝生产中用高锰酸钾碱液低温浸泡取代高温碱煮，可显著提高表面质量；固熔处理加热温度控制在１０２０～１０４０℃，保温时间２０～３０ｍｉｎ，成品拉拔压缩率控制在１７％～２０％，其强度为６８５～９３０ＭＰａ，速度６５～７５ｍ／ｍｉｎ，以消除钢丝铁磁性反应，完全满足制钉钢丝质量要求。

To produce 175～40mm stainless steel wire with material SUS304,then use it to make fluted twist nailSubstituting low temperature immersing with KMnO4 lye for high temperature alkaline boiling in steel wire production can notably improve the surface qualityHeating temperature of solution treatment is controlled at 1 020～1 040℃,thermal insulating time is 20～30min,condensation of end products drawing is controlled at 17%～20%,its strength is 685～930MPa,drawing speed is 65～75m/min,so as to clear up the ferromagnetic reaction of steel wireIt can completely meet the quality demands of nail making
