摘要
介绍了合金钢精线生产现状及存在问题,分析了热轧材表层结构及退火前酸洗对磷化和冷成型的影响。重点分析了氧化铁皮对退火产品质量、磷化质量、冷成型的影响。认为合金钢精线在退火前进行酸洗是很有必要的。
This paper introduces the production situation and existing problems of alloy steel,analyzes surface structure of hot rolled steel and the influence of pickling before annealing on phosphating and cold forming.The influence of iron oxide skin on the quality of annealed products,the phosphating quality and cold forming is emphatically analyzed.It is thought that the alloy steel refined wire is necessary to anneal before pickling.
