摘要:
本文从热力学和动力学两方面综述了镀铝锌硅(Galvalume，简称GL)生产过程中锌渣的研究现状，阐明了热镀GL中锌渣的生成机理。从热力学角度讨论了熔池温度和Si含量对锌渣及Fe溶解度的影响。发现随着温度的升高，FeAl3相优势区变大；随着Si含量增加，α-FeAlSi稳定锌渣相逐渐向α-FeAlSi+FeAl3稳定锌渣相转变；Fe在GL中的溶解度随温度的升高而增加，当Si含量为1.6%时，Fe的溶解度最大。从动力学角度讨论了Fe在GL熔池中的溶解过程，总结了浸镀速度对Fe溶解速率的影响及沉没辊结渣机理。发现随着浸镀速度的增加，Fe的溶解速率增加，并改变了熔池的溶度场、温度场及流场分布，容易产生小而轻的悬浮渣。
Abstract:
This paper reviews the recent development dross in Galvalume (GL) production from thermodynamics and kinetics. The effects of GL bath temperature and Si content on the balance of zinc slag and the solubility of Fe were discussed thermodynamically. It is suggested that the FeAl 3 phase becomes larger as the temperature increases. Besides, the α- FeAlSi dross phase gradually transformes into α-FeAlSi+FeAl 3 phase with the increase of Si content. The solubility of Fe in GL increases with temperature increasing. While the Si content is 1.6%, the solubility of Fe reaches to the peak. The effect of immersion rate on Fe dissolution and the mechanism of sinking slagging in GL are discussed. The dissolution rate of Fe increases with the increase of immersion rate, changeing the solubility field, temperature field and flow field distribution and suspension slag in GL bath.
