【摘要】 长期以来对热轧板、卷等钢材表面进行除鳞处理一般采用酸洗技术。由于酸具有腐蚀性，会对产品表面质量和性能产生影响，对操作人员和设备也存在一定程度的损害，同时污染生产环境。随着国家环境保护更加严格政策的强化落地，要求相关企业实现污染物零排放。国内外研究机构都加大了对热轧钢材除鳞技术设备的研究力度，研发出了更环保除鳞的新技术和新工艺。本文对现阶段已得到应用的免酸洗除鳞技术的特点进行了介绍、综合对比，并指出热轧钢材除鳞技术低成本、免酸洗的发展方向。更多还原

【Abstract】 For an extended period, pickling technology has been widely employed for surface descaling of hot-rolled plates, coils, and other steel products. However, the corrosive nature of acids not only compromises the surface quality and performance of treated products but also causes damage to operators and equipment, while polluting the production environment. Against the backdrop of increasingly stringent national environmental protection policies, enterprises are now mandated to achieve zero pollutant emissions. In response, domestic and international research institutions have intensified their efforts in investigating descaling process technologies and equipment, leading to the development of more environmentally friendly novel techniques and processes. This paper conducts a comprehensive comparative analysis of the current applications of acid-free descaling technologies and proposes that the future development direction of hot-rolled product descaling technology lies in low-cost, acid-free solutions.更多还原
