为进行磷酸盐系无铬无取向硅钢涂层烧结固化工艺研究,首先对磷酸盐系无铬无取向硅钢涂层进行热重-差示扫描量热(TG-DSC)分析;然后在不同烧结固化温度条件下,测定涂层板温随时间变化曲线;最终获得涂层烧结固化温度与时间(T-t)工艺曲线。通过中性盐雾试验、动电位极化、交流阻抗、涂层附着力以及扫描电子显微镜(SEM)和能谱(EDS)分析验证。结果表明,根据涂层烧结固化温度与时间(T-t)工艺曲线制备的涂层结构致密、性能优异,证明该工艺曲线具有合理性与正确性。 In order to study the curing process of chromium-free non-oriented silicon steel coatings,phosphatic chromium-free non-oriented silicon steel insulating coating was prepared and TG-DSC analysis of the coating was conducted,then the change of the actual temperature of the coated non-oriented silicon steel sheet with time at different curing temperatures was studied. Based on the experiments,the processing curves of curing temperature vs. curing time( T-t) for the chromium-free non-oriented silico... 

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.
