在采用改良森吉米尔法的热镀锌机组中 ,无氧化工艺由于技术复杂 ,控制及操作难度大 ,对产品质量、产量影响显著 ,被称作“核心工艺”。结合生产实践探讨了无氧化工艺对连续热镀锌板锌层附着性的影响 ,提出了“挡墙理论” In the hot galvanizing plant adopting the modified Sendzimir method, the non-oxidative process is known as the “core process” because of its complicated technology, difficulty in controlling and operating, and significant impact on product quality and output. Combining with the production practice, the effect of non-oxidative process on the adhesion of zinc coating on continuous hot-dip galvanized sheet was discussed. The “retaining wall theory”
