摘要
厚规格镀锌产品沉没辊印缺陷一直是包钢热镀锌机组的瓶颈问题。通过采用XRD物相分析法对沉没辊结渣成分进行分析,影响厚规格镀锌产品沉没辊印缺陷主要因素为锌液温度、锌液Al含量、带钢清洗质量以及镀后冷却塔张力控制,针对影响因素制定有效的控制措施,从根本上减轻或消除了厚规格镀锌产品沉没辊印缺陷。
The sink roll mark defect of thick gauge hot-dipped galvanization products is always the bottleneck problem of hot-dip galvanizing line of Baotou Steel.The slagging composition of sink roll is analyzed with the XRD phase analysis.The main factors influencing the defect are the temperature of liquid,Al content of liquid zinc,cleaning quality of strip steel and tension control of cooling tower after galvanizing.The effective control measures are formulated based on the influence factors so that the defect is relieved or eliminated fundamentally.
