以太钢热连轧厂的硅钢为研究对象,利用凸度仪测量热轧带钢出口凸度值,采用矩阵和失效模式的分析方法了解影响带钢凸度变化的主次因素。研究结果表明:通过有效控制轧制过程中的加热温度、时间及采用合理的辊型,硅钢凸度精度提高了4.34%左右。 In this paper,we take the hot-rolled silicon steelsheet of Taigang as the research symbol,exit profile was measured by convex instrument,the primary and secondary factors that affect the strip profile were measured by using matrix and failure mode analysis methed.The results indicate that convexity accuracy has significantly improved by nearly 4.34% through the effective control of the heating temperature,heating time and the use of correct roller type in the process of hot rolling. 

分析了太原钢铁(集团)有限公司第二炼钢厂80 t RH生产冷轧硅钢脱碳、脱硫原理及影响因素,认为通过合理控制RH到站钢水碳和氧含量、加大插入管内径、采用快速抽真空度等可提高脱碳效果。降低顶渣中FeO和MnO含量,保证脱硫剂加入后的循环时间可以提高RH脱硫率。 The present article analyzes the principle of decarburization and desulfurization in refining the cold rolled silicon steel in the 80 t RH in No.2 Steelmaking Plant of Taiyuan Iron & Steel(Group) Corp.,and its influencing factors.It’s determined that the decarburization effect can be achieved by properly controlling the cabon and oxygen contents in the hot metal coming into the RH station,enlarging the inner diameter of snorkel and adopting the fast evacuation method.In the meanwhile the des... 

对1990~2010年在我国申请的冷轧无取向硅钢涂层的专利数量、专利技术领域分布进行了统计,对典型涂层专利技术进行了分析,探讨了无取向硅钢涂层的发展趋势。统计分析结果表明,目前无取向硅钢涂层典型的专利技术主要有自粘结涂层、无铬含稀土元素涂层、含钼酸盐环保涂层及采用有机-无机纳米杂化材料为主成膜物形成的涂层等。无取向硅钢涂层发展的趋势主要是无铬环保的半无机、半有机型涂层。 The patent quantity of cold-rolled non-oriented silicon steel coating and distribution of technology fields applied in China in 1990-2010 were summarized.The analysis results indicate that typical patent technologies include self-adhesion coating,chromium-free and with rare earth element coating,environment-friendly and with molybdate coating,coatings with organic-inorganic hybrid materials as main forming agent and so on.The main development trends of coatings on silicon steel are among semi-in...
