中文摘要: 非接触式的电磁抹拭工艺在热镀锌行业的应用,可实现该行业高速、低耗、绿色生产。在提高热镀锌行业经济性的同时,对促进该行业节能、降耗具有重大的社会意义。磁场在提供洛伦兹力作为镀层抹拭力的同时,也通过改变原子扩散的驱动力和界面反应影响热镀锌过渡层金属间化合物的组织结构和生长动力学。本项目利用磁场对原子扩散和界面迁移的影响,研究磁场中热镀锌过镀层金属间化合物的微观晶体结构、晶体取向、生长动力学及组织形貌演变规律。通过本项目研究能够加深磁场对影响原子扩散和界面迁移的理解,丰富界面金属间化合物在磁场中生长动力学理论,对磁场下相关冶金现象的理解和分析提供理论指导依据,具有一定的科学指导意义。同时对于完善热镀锌过渡层形成机理,指导热镀金属行业技术革新也有着重要的作用。

英文摘要: Non-contacting electromagnetic wiping technology application in hot dip galvanizing industry applications, can achieve the high speed, low consumption and green production. This can improve the conomic benefits and Social results of hot galvanizing industry. Magnetic field can apply Lorenz power as the coating wiping force, and also can change the driving force of the atomic diffusion and interface reaction. This can affect intermetallic compound structure and growth kinetics of hot dip galvanized transition layer. Through the effects of magnetic field on the atomic diffusion and interface migration, the crystal structure, crystal orientation, growth kinetics and morphology evolution of intermetallic compounds in hot dip galvanizing coatings will be studied in this project. Study of this project can promote understanding the effects of magnetic field on atomic diffusion and interface migration, can enrich the growth dynamics theory of interface intermetallic compounds in magnetic field, also can contributed to understanding and analyzing metallurgical phenomenon. It also can improve the formation mechanism of hot dip galvanized transition layer, and can guide the hot metal plating industry technology innovation.
