摘要
使用 X 射线衍射、电子背散射衍射和场发射扫描电子显微镜研究了不同稀土 Ce 含量的无取向硅钢热轧薄板的宏观和微观纹理,并使用硅钢片测试系统检测了冷轧退火薄板的磁性能。结果表明,稀土 Ce 的加入降低了钢中不利的 γ 纹理强度和{111}纹理的比例,提高了钢中有利的 η 纹理强度和{100}、{110}纹理的比例。磁性能测试表明,稀土 Ce 有利于降低试验钢的损耗和提高磁感应强度。主要原因是稀土 Ce 与钢中的 O 和 S 结合形成大尺寸夹杂物,优先在钢液中析出,抑制了细小 AlN 和 MnS 夹杂物的析出,同时将夹杂物变性为 Ce2O2S-MnS、CeS-AlN 和 CeAlO3 等球形复合夹杂物,从而起到净化钢液和变性夹杂物的良好效果。
Effect of rare-earth Ce on the texture of non-oriented silicon steels
Macroscopic and microscopic textures of non-oriented silicon steel hot rolled sheets with different rare-earth Ce contents were investigated using X-Ray Diffraction, Electron Back Scatter Diffraction, and field emission scanning electron microscopy, and the magnetic properties of the cold-rolled annealed sheets were examined using a silicon steel sheet testing system. The results show that the addition of rare-earth Ce reduces the proportion of unfavorable γ texture intensity and texture {111} and enhances the proportion of favorable η texture intensity and texture {100} and {110} in the steel. Magnetic property tests show that rare-earth Ce favors the reduction in test steel loss and the increase in magnetic susceptibility. The main reason is that rare-earth Ce combines with O and S in steel to form large-size inclusions, which preferentially precipitate in the liquid steel and inhibit the precipitation of fine AlN and MnS inclusions, while denaturing the inclusions to spherical composite inclusions such as Ce2O2S-MnS, CeS-AlN, and CeAlO3, thus exerting a good effect of purifying the liquid steel and denaturing the inclusions.
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
