一、前言近年来采用连铸钢作镀锡板的基本材料有很大的增加。然而,连铸钢和沸腾钢的铸锭相比较含有较高的 Si 和 Al。许多试验证明,钢中这些元素在箱式退火中趋向于富集在钢的表面。本研究旨在探讨镇静钢薄板表面富集的 Si、Al 和 Mn 对镀锡板耐蚀性的影响。 I. Introduction In recent years, the basic material of continuous casting steel for tinplate has been greatly increased. However, continuous cast steel and ingot cast ingot contain higher Si and Al. Many tests have shown that these elements in steel tend to be enriched in the steel surface during box annealing. The purpose of this study is to investigate the effects of Si, Al and Mn enriched on the surface of killed steel sheet on the corrosion resistance of tinplate.
