整体模拉法生产Z型钢丝

介绍整体模拉法生产Z型钢丝的工艺流程。采用旋转模盒进行拉丝模定位,保持拉拔过程中拉丝模方向一致,满足钢丝在拉拔过程中各道次及成品钢丝的尺寸精度;改善拉拔过程中模盒的水冷效果,降低钢丝拉拔过程发热量,提高拉拔效果;改进磷化表面处理工艺;合理分配道次压缩率。通过改进,生产的Z5.0(AB1-T),Z5.0(AB2-T)和Z6.0(AB1-T)3种规格的异型丝弯曲可达19次,扭转达26次,抗拉强度为1570 MPa,确保了成品的外观尺寸和力学性能,解决了常用辊轧生产工艺精度低、强度低的缺陷。

Z-type steel wire production by die drawing way

To introduce the process flow of Z-type steel wire production by die drawing way. It can meet precision of each pass of drawing course and finished steel wire to locate wire drawing die by adopting rotation die box and to keep die direction same in the course of wire drawing; improving water cooling effect of die box and reducing calorific value in the course of wire drawing to raise drawing effect ; to improve phosphating surface treatment and rational draught distribution. By im- proving, the bending value of three kinds of specification shaped wire Z5.0（ AB1 - T）, Z5.0（ AB2 - T）, Z6.0（ AB1 - T） all reach 16 times, torsion value surpass 26 times, tensile strength 1 570 MPa, and ensure appearance size and mechanical properties of finished wire, the defects such as low precision and strength by common roller rolling means are settled.
