Description
技术领域
本发明涉及一种Z型密封钢丝生产方法，属于金属压力加工制品领域。
背景技术
目前国内大部分用户采用的密封钢丝绳，其外层为Z型钢丝。Z型钢丝是密封钢丝绳的关键部分，其性能及加工决定了密封钢丝绳的性能和成本，故需保证钢丝性能和其生产成本，以适应市场需求。
发明内容
本发明所要解决的是如何生产高强度、高韧性异型钢丝，为满足目前市场及用户对密封钢丝绳高强度要求的技术问题。
为了解决上述技术问题，本发明采用如下技术方案：
一种Z型密封钢丝生产方法，包括以下具体步骤：
步骤一：将直径为Φ14mm的70#盘条，放入酸洗槽内进行酸洗后，再放入磷化槽内进行磷化表面处理，盘条磷化膜厚度为≥9g/m2；
步骤二：再将步骤一处理后的盘条，采用9/1270拉丝机进行拉拔，拉拔时第一道次采用旋转模盒，第二至九道次采用选用固定模盒，拉拔过程中严控润滑水冷后,生产出Z6型密封钢丝。
采用上述技术方案的有益效果是：
本发明生产出Z6型密封钢丝具有高强度、高韧性的异型钢丝，能满足目前市场及用户对密封钢丝绳的高强度的要求。
附图说明
图1为本发明Z6异型钢丝成品尺寸结构示意图。
具体实施方式
下面对本发明作进一步详细说明：
1、原料：
φ14mm 拉拔到Z6型密封钢丝时，由于总压缩率较大，达到82.67%，为后续拉拔顺利，盘条在表面处理后盘条磷化膜厚度需≥9g/m2。
为了提升酸洗效果，改变酸洗槽内的盐分的组成，使酸洗后的表面状态达到最佳。
盐酸洗槽的工艺参数
酸洗时间控制在600s左右，为提升酸洗效果，防止盐酸腐蚀钢基，在酸洗是应添加4‰—8‰的缓蚀剂。
磷化时为提高磷化膜的质量，确保磷化膜面质量达到8.5—10g/mm2。磷化表面光滑、致密，磷化时提高磷酸总酸度。
磷化槽参数
2、钢丝拉拔
Z6型密封钢丝截面积为26.66,mm2，面积相当于直径为Ф5.83mm圆钢丝截面积，φ14mm 70#盘条原始强度≥1020MPa，根据屠林科夫公式：
将数据代入公式
故钢丝拉拔后，强度能达到1670MPa。
钢丝在拉拔时，采用1块圆模+2块椭圆模+6块异型模的拉拔工艺，第一道次旋转模盒用12.9mm的圆模，拉拔时第一道次采用旋转模盒，确保钢丝表面质量；第二道次固定模盒用椭圆模，长轴尺寸为12.5 mm，短轴尺寸为11.98 mm；第三道次固定模盒用椭圆模，长轴尺寸为11.65mm，短轴尺寸为11.04mm；第四道次固定模盒用异型模，对角线为10.82mm；第五道次固定模盒用异型模，对角线为10.36mm；第六道次固定模盒用异型模，对角线为9.96mm；第七道次固定模盒用异型模，对角线为9.56mm；第八道次固定模盒用异型模，对角线为9.20mm；第九道次固定模盒用异型模，对角线为8.9mm。钢丝在拉拔过程中，必须保证大小面方向一致，钢丝进模具前不能打扭，否则会造成模具寿命短、钢丝表面挂伤、钢丝塑性降低等缺陷。
所述Z6型密封钢丝拉拔后强度为≥1670Mpa。
所述Z6型密封钢丝大面与小面之间的高度为6mm，允许尺寸偏差为±0.05mm；对角线尺寸为8.90mm，大面尺寸为4.90mm，小面尺寸为4.22mm，钢丝截面积为26.66mm2。
