摘要:: 低碳热镀锌钢丝是金属制品领域的重要产品。通过对开裂现象的宏观形貌和显微组织的观察，本论文对低碳热浸镀锌钢丝调直开裂现象进行原因分析。试验结果表明，钢丝开裂的主要原因是镀层中锌铁合金层过厚及调直压力过大。为此，实验研究中系统调整了热镀锌生产工艺及镀后冷却工艺，将镀层中的合金层厚度控制在10～15 μm范围；同时，调整了调直机轮型、距离等工艺参数。调整工艺后加工的低碳热浸镀锌钢丝未出现开裂现象。

Abstract:: Low-carbon hot-dip galvanized wire is an important product in the field of metal products. By observing the macroscopic morphology and microstructure of the cracking phenomenon, this paper analyzes the causes of straightening cracking in low-carbon hot-dip galvanized steel wire. The experimental results indicate that the main cause of steel wire cracking is the excessive thickness of the zinc-iron alloy layer in the coating and the excessive straightening pressure. Therefore, in the experimental study, the production process of hot-dip galvanizing and the post plating cooling process were systematically adjusted to control the thickness of the alloy layer in the coating at 10-15 μm. At the same time, process parameters such as straightening machine wheel type and distance were adjusted. The low-carbon hot-dip galvanized steel wire processed after adjusting the process did not exhibit any cracking phenomenon
