摘　　要：为提升冷轧镀锌钢板的耐腐蚀性,提高产品的市场竞争力,针对冷轧镀锌生产过程中频繁发生的锌层厚度均匀性较差的问题,以180 g及以上冷轧镀锌产品的生产数据为依据,研究其产生的原因,通过对镀锌生产工艺进行优化,规范生产过程的实际操作,提高设备精度,使冷轧镀锌锌层厚度方差由100以上降低到20以下,产品质量提升,降本增效显著。To improve the corrosion resistance and market competitiveness of cold-rolled galvanized steel sheets,this research focuses on resolving the persistent issue of non-uniform zinc coating thickness during manufacturing.Based on production data from products with zinc coating weights of 180 g and above,a systematic analysis identified key contributing factors,By optimizing galvanizing process parameters,standardizing operational protocols,and upgrading equipment precision,the variance in coating thickness was successfully reduced from over 100 to below 20,resulting in enhanced product quality and significant economic benefits.
