绝缘涂层可以有效提高硅钢片的耐蚀、耐腐、磁、绝缘等性能，因此取向硅钢涂装绝缘涂层是取向硅钢生产过程中重要的一环。本文对取向硅钢含铬无机绝缘涂层以及氮化铬涂层的性能优缺点进行了介绍，并对国内无机含铬取向硅钢绝缘涂层及氮化铬涂层的研究现状进行了综述。最后对未来含铬无机绝缘涂层的研发方向进行了展望。 Insulation coating can effectively improve the corrosion resistance of silicon steel sheet, such as corrosion, magnetic, insulation performance, thus oriented silicon steel insulation coating is the important part of oriented silicon steel production process. In this paper, the inorganic insulation coating oriented silicon steel containing chromium and chromium nitride coating performance advantages and disadvantages are introduced.In addition, the research status of insulation coating and chrom... 

采用自主研发的脉冲磁场退火装置，在取向硅钢脱碳退火过程中分别施加不同强度的磁场，并采用光学显微镜和X射线衍射仪研究了脉冲磁场脱碳退火后试样的显微组织和宏观织构。结果表明，脱碳退火过程中施加脉冲磁场后取向硅钢的平均晶粒尺寸均增加，当磁场强度为40 mT时，平均晶粒尺寸最大，为13.06μm。此外，取向硅钢试样的立方织构{001}<100>强度减弱，高斯织构{110}<001>和{111}<112>织构增强，有利于获得更好的成品织构和磁性能。 Self-developed pulsed magnetic field annealing device was used to apply magnetic field of different intensities during decarburization annealing of an oriented silicon steel, and microstructure and macro-texture of the specimens after decarburization annealing in a pulsed magnetic field were studied by using optical microscope and X-ray diffractometer.

某厂对电工钢的轧制策略进行了优化，粗轧道次由“1+5”改为“1+3”。在优化后的生产过程中，每次变换钢种，烫辊材就会出现窄尺现象，而紧随其后的电工钢板则出现超宽现象。文中针对该问题，介绍了宽度设定模型和宽度自适应模型的原理，阐述了该问题出现的原因及解决方案，并通过对宽度自适应模型的应用研究及优化攻关，有效地解决了问题，大幅提升了实物质量，降低了宽度封锁率。 The rolling strategy of electrical steel was optimized in a factory,and the rough rolling pass was changed from “1+5”to“1+3”.Subsequently,the following problems were occurred in the production process:when the steel grade changed,the roasting roller steel before the electrical steel appeared the narrow width phenomenon,and then the electrical steel appeared the ultra-wide phenomenon.This paper introduced the principle of width setting model and width adaptive model,and expounded the causes and s... 

磁性能指标是硅钢产品最关键的质量指标之一，但是目前磁性能判定100%依赖于样品的离线实验室检测结果，生产线配置的在线检测仪的测量结果由于精度问题，不宜直接用于成品牌号判级。本文在现有硅钢产品质量管控体系基础上，利用大数据技术对生产数据进行分析与建模，构建不同磁性能指标在线检测模型，并在现有信息系统上完成模型库的集成部署，实现硅钢产品全长、多指标磁性能结果的拟合数据输出，支撑取样优化、精准分切、辅助综合判定等功能应用，进一步优化硅钢产品质量管控体系。 The magnetic performance index of silicon steel products is one of the most critical quality indexes.However,at present,100%determination of magnetic performance depends on the offline laboratory test results of samples,and the measurement results of the online detector configured in the production line cannot be applied in practice due to the accuracy problem.Based on the existing quality control system of silicon steel products,big data technology was used to analyze and model the production d...
