Abstract

The paper is focused on a comparison of the magnetic properties of the non-oriented isotropic electrical steel containing 3.5% Si. The material was processed by conventional ambient temperature rolling and progressive rolling at the cryogenic conditions at liquid nitrogen. Deformations of the samples in both thermal conditions were in the interval εÎ<5;35>[%]. Subsequently, the samples were heat treated at temperatures TÎ<900;1100> [°C]. Measuring of the magnetic properties was carried out in an alternating magnetic field at frequencies f= 50; 100; 150 Hz. At a frequency of 50 Hz were achieved smallest magnetic losses and therefore further measurements were made at a given frequency. Followed measurements of the magnetic induction were conducted at different intensities of the magnetic field. EBSD analyses were performed to obtain the IPF maps on which the resulting structure was evaluated after processing of the material. The specific magnetic losses were compared to different processing methods. The best magnetic properties defined as by minimal values of core loses were reached after samples rolled at cryogenic temperature followed by subsequently annealed. Also, higher proportion of cubic texture was archived after rolling at cryogenic temperature with compared to samples processed at ambient temperature.

退火温度对冷轧无取向电工钢磁性能的影响

本文对含3.5% Si的无取向各向同性电工钢的磁性能进行了比较。采用常规常温轧制和液氮低温条件下的连续轧制两种方法对材料进行了加工。两种热条件下试样的变形量在εÎ[%]区间内。随后，样品在TÎ[°C]温度下进行热处理。在频率为f= 50的交变磁场中进行磁性测量;100;150赫兹。在50赫兹的频率下实现了最小的磁损失，因此在给定的频率下进行了进一步的测量。随后在不同强度的磁场下进行了磁感应强度的测量。进行EBSD分析以获得IPF图，在此图上对材料处理后的所得结构进行评估。比较了不同加工方法的比磁损耗。样品经低温轧制后再退火后，磁性能达到最佳，即磁芯损耗最小。此外，与常温下处理的样品相比，低温轧制后的样品中立方织构的比例更高。

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.
