摘　　要：对热轧低碳钢直接还原热镀锌的工艺进行了模拟试验研究,分析了氢气还原退火时间及氢气浓度对氧化铁皮形貌、镀层形貌及镀层附着力的影响。结果表明,还原退火时间及氢气浓度对氧化铁皮形貌和镀层有很大影响,而对镀层附着力影响不大。Direct reduction hot dip galvanizing technology of hot rolling low carbon steel was studied by simulation experiments,influences of annealing time and hydrogen concentration on scale morphology,coating morphology and coating adhesion were analyzed.Results show that annealing time and hydrogen concentration have important influence on scale morphology and coating,but less influence on coating adhesion.
