<p>热镀锌的锌锭消耗占整个镀锌工序加工成本的50%，对于镀锌生产线降低锌锭消耗是降低成本的关键。他们认真分析，发现带钢在热镀锌生产过程中锌锅产生大量锌渣和氧化锌;带钢表面超出合同或者用户要求的部分锌重，是造成锌锭消耗高成本原因。针对问题，作业区深入研究，广泛征集建议，制定了合理的加锌制度、捞渣周期、锌锅液位、锌锅温度、锌液成分、气刀高度措施等，合理控制炉内、定时清理，减少钢带表面残铁量，精确稳定控制锌锅的工艺参数，减少锌渣的产生。同时，对镀层厚度进行精确控制，通过提高操作水平，控制张力减小带钢抖动，保证镀层的均匀性。目前该作业区吨钢节约锌耗2.46公斤，吨钢加工费降低34.44元，每月降低成本200余万元。</p>
