摘　　要：在热镀锌线生产中,镀锌板材的表面质量是衡量产品质量的最为重要的指标,热镀锌产品表面质量缺陷主要有表面镀层划伤、气刀条痕、漏镀、表面锌花、表面锌渣、镀层厚度不足等,这些都会严重影响镀锌产品的加工使用,引起客户的异议。针对多种缺陷问题,分析热镀锌线产品质量缺陷的产生原因,并从热镀锌生产工艺过程角度考虑,采取调整锌锅区带钢张力、调整气刀参数、及时清理锌渣等控制措施,有效消除了产品质量缺陷。In the production of hot-dip galvanizing lines,the surface quality of galvanized sheets is the most important indicator to measure product quality.The surface quality defects of hot-dip galvanized products mainly include surface coating scratches,air knife marks,missed plating,surface zinc splashes,surface zinc slag,insufficient coating thickness,etc.These can seriously affect the processing and use of galvanized products,causing customer objections.In response to various defect issues,the causes of quality defects in hot-dip galvanizing line products were analyzed.From the perspective of hot-dip galvanizing production process,control measures such as adjusting the tension of the strip steel in the zinc pot area,adjusting the parameters of the air knife,and timely cleaning of zinc slag were taken to effectively eliminate product quality defects.
