建筑用Zn-Al合金钢丝生产及检测

Production and inspection of Zn-Al alloy steel wire for building

介绍Zn-Al合金钢丝应用范围和技术要求,详细说明生产工艺和控制要点,并结合生产分析表面光洁度、锌瘤等问题产生原因,提出相应措施。对不同直径钢丝进行力学性能检测和组织分析,结果表明,Zn-Al合金钢丝技术指标满足GB/T 20492—2006要求,Zn-Al合金钢丝比纯锌镀层钢丝耐腐蚀平均速率低0.017 150 20 g/(m2·h),满足客户对Zn-Al合金钢丝要求。

The application range and technical requirements of Zn - A1 alloy steel wire are introduced. The production process and control points are described in detail. The causes of surface finish and zinc lump are analyzed combined with production, and corresponding measures are put forward. Analysis of mechanical properties test and microstructure on steel wire with different diameters. The results show that the technical specifications for Zn -A1 alloy steel wire to meet the re- quirements of GB/T 20492--2006 , The average corrosion resistant rate of Zn - A1 alloy steel wire is lower 0. 017 150 20 g/（m^2·h）, than pure zinc coated steel wire, and meet the requirements of customers Zn- A1 alloy steel wire
