摘要
介绍用两步法热镀Zn5%AlRE合金镀层钢丝生产工艺技术。镀前处理采用了加长脱脂炉和酸洗工序,复镀合金出口处采用氮气保护擦拭,热镀温度420~440℃,DV值46~48,钢丝冷却速率30~60℃/s。用此工艺热镀23mm钢丝镀层重量可达256g/m2,各项性能指标合格。
To introduce the production technology of hot dipping Zn 5%Al RE alloy coating steel wire with two step method Elongating degreasing furnace and pickling process are adopted in fore treating Nitrogen protected wiping is adopted at the exit point of recoating alloy Hot dipping temperature is in the range of 420~440?℃,DV value is 46~48,cooling rate of steel wire is 30~60?℃/s The coating weight of 2 3?mm steel wire hot dipped with the technology can reach 256?g/m 2,every property indexes of the product are up to standard
