- 带钢连续热镀锌是目前应用最广泛且具有经济性的防腐技术。然而，热镀锌过程难免会产生锌渣，锌渣的形成不仅会造成锌资源的损失，也会严重影响带钢的表面质量，因此控制锌渣的形成是带钢热镀锌质量控制的关键点。笔者综述了近年来国内外带钢连续热镀锌锌渣缺陷的研究现状，分析了锌渣的形成机理，探讨了锌渣的影响因素，总结了锌渣的控制措施，证明通过一系列设备改进、工艺优化和规范操作等调整，可有效减少锌渣、降低锌耗、节省成本、提高质量。同时，对热镀锌技术锌渣缺陷的进一步有效预防与控制进行了展望。
- Abstract:
- Continuous hot dip galvanizing is currently the most widely used and cost-effective anti-corrosion technology. However, the hot dip galvanizing process inevitably produces zinc slag. The formation of zinc slag not only causes the loss of zinc resources, but also seriously affects the surface quality of the strip steel. Therefore, controlling the formation of zinc slag has become the key point in the quality control for hot dip galvanizing of strip steel. In this paper, the research status of zinc slag defects in continuous hot dip galvanizing of strip steel at home and abroad in recent years is reviewed. The formation mechanism of zinc slag is analyzed, the influencing factors of zinc slag are explored, and the control measures of zinc slag are summarized. It is proved that through a series of equipment improvements, process optimization, and standardized operation adjustments, the zinc slag can be effectively reduced, zinc consumption can be reduced, costs can be saved, and quality can be improved. At the same time, the further effective prevention and control of the zinc slag defects in hot dip galvanizing technology are prospected
