摘　　要：为了能在一条热镀锌生产线上同时生产架空绞线用镀锌钢丝及铠装电缆用热镀锌低碳钢丝,对现有工艺和生产设备做出改进:(1)铠装电缆用热镀锌低碳钢丝离线退火,架空绞线用镀锌钢丝在线脱脂;(2)采用陶瓷材质固定式压线辊;(3)铠装电缆用热镀锌低碳钢丝增加阻力调节装置;(4)选用镍铬-考铜热电偶对退火炉的测温仪器进行改进,测温点位于退火炉的中部。通过上述工艺及设备改进,生产的Ф1.6 mm铠装电缆用钢丝锌层面质量153～178 g/m2,抗拉强度375～440 MPa,扭转40～53次;2.25～2.75 mm绞线用钢丝锌层面质量237～269g/m2,抗拉强度1390～1570 MPa,扭转22～30次,均满足GB/T 3428—2002要求。In order to produce galvanized steel wire for overhead steel strand and hot galvanizing low carbon steel wire for armoured cable at the same time in one hot galvanizing production line, the present process and production equipment are improved as following ： （ 1 ） hot galvanizing low carbon steel wire for armoured cable offline annealing, galvanized steel wire for overhead steel strand online degreasing, （2） to adopt ceramic material fixed line pressing roller, （ 3 ） to add resistance adjusting device on hot galvanizing low carbon steel wire for armoured cable, （4）nickel-chromium, exam copper thermocou- pie is selected to improve thermometer of annealing furnace, temperature measuring point lies in middle part of annealing furnace. After improvement of above process and equipment, the zinc coating surface quality of diameter 1.6 mm steel wire for armoured cable is 153 ~ 178 g/ms , tensile strength is 375 ~440 MPa, torsion value is 40 -53, the zinc coating surface quality of diameter 2.25 - 2.75 mm steel wire for strand is 237 ~ 269 g/m2, tensile strength is 1 390 - 1 570 MPa, torsion value is 22 ~ 30, which meet GB/T 3428--2002 requirements.
