摘要:
针对热镀锌产品镀层白条缺陷，研究了其形成机理、影响因素和控制措施。结果表明，白条缺陷由炉鼻子内锌灰黏附于带钢表面而形成，其成分是 Zn 和 ZnO 。白条缺陷影响因素主要有炉鼻子密封性、露点、带钢入锌锅温度、锌锅温度和排锌灰效果。通过对上述因素进行控制及优化，有效地消除白条缺陷，达到家电用钢表面质量需求。
Abstract:
： The formation mechanism ， influencing factors ， and control measures of white bar defects in hot-dip galvanized products were studied. The results indicate that the white bar defect is formed by the adhesion of zinc ash inside the furnace nose to the surface of the steel strip ， and its components are Zn and ZnO. The main factors affecting the white bar defect are sealing of the furnace nose ， dew point ， temperature of the steel strip entering the zinc pot ， zinc pot temperature ， and zinc ash removal effect. By controlling and optimizing the above factors ， the white bar defect can be effectively eliminated to meet the surface quality requirements of steel for household appliances.
