摘要
Abstract
The conventional grain-oriented ( CGO) silicon steel containing copper is a type of grain-oriented steel with low cost and high productivity. The processing parameters in CGO steels are quite different to those of low temperature heating and nitriding high permeability ( HiB) grain oriented silicon steels, the fluctuation range of the magnetic properties in CGO is much higher than that of ni-trided HiB steels. In this study, typical final sheets from production lines of CGO steels containing copper during early stage production were collected, and the structure, texture, and magnetic properties were determined and compared to establish a relationship between the structure of the steels and inhibitors and to elucidate the reasons for property fluctuation. The results indicate that the macrostruc-ture in the final sheets has a relationship with inhibitors and that the grain sizes do not show monotonous behavior. In addition, the de-fective microstructure in hot-rolled bands and intermediately annealed sheets are investigated and a coarse grain region and a decarburi-zed surface layer are observed. Such regions are considered to influence the inhibitor distribution and impact the fluctuation in structure and its properties.关键词
