Resumo: Siliceous steels are the ones that contain a percentage of approximately 3% silicon and they are used to manufacture generators, transformers and industrial motors. Through the research, understand their metallurgical properties about electrical steel and also conciliate these properties with processes parameters from this material. A standard sample taken from the batch selected for testing was pickled using hydrochloric acid and subjected to the annealing procedure. Proportional calculations were made using the iron silicon diagram, taking into account the weight and dimensions of the sample. After annealing, the sample was submitted to the appropriate tests to show grain size and its influence on magnetic properties. The results showed significant growth in grain size after secondary annealing and generation of the Goss texture, which is desired for the material. By the analyses was possible conclude that after annealing process, the grain showed standard size, and the magnetic loss and permeability resulted in 1,5 W/Kg and 1,99T respectively at 1,7T induction condition at 60Hz frequency (Brazilian standard frequency).

La investigación fue hecha con el propósito de generar conocimiento metalúrgico acerca de las propiedades magnéticas de los aceros eléctricos y también conciliar esas propiedades a los parámetros de procesamiento del material. Una muestra estándar fue retirada del lote seleccionado para prueba, decapada utilizando ácido clorhídrico y sometida al proceso de recocido. Los cálculos de proporcionalidad se realizaron utilizando el diagrama de hierro silicio, teniendo en cuenta el peso y las dimensiones de la muestra. Después del recocido, la muestra fue sometida a las pruebas adecuadas para evidenciar el tamaño de los granos y su influencia en las propiedades magnéticas. Sus resultados mostraron un crecimiento significativo en el tamaño de los granos después del recocido secundario, y la generación de la textura goss, que se desea al material. Con los análisis fue posible concluir que después del recocido, los granos presentaron tamaños estandarizados y bien ordenados, y la estandarización de las pérdidas y permeabilidad magnética que respectivamente resultaron en 1,5 W / Kg y 1,99T en las condiciones de 1,7T a una frecuencia de 60 Hz (frecuencia estándar brasileña).Os aços siliciosos são aqueles compostos de aproximadamente 3% de silício e são utilizados para fabricação de geradores, transformadores e motores industriais. A pesquisa foi feita com o intuito de gerar conhecimento metalúrgico acerca das propriedades magnéticas dos aços elétricos e também conciliar essas propriedades aos parâmetros de processamento do material. Uma amostra padrão foi retirada do lote selecionado para teste, decapada utilizando ácido clorídrico e submetida ao processo de recozimento. Cálculos de proporcionalidade foram feitos utilizando o diagrama ferro silício, levando em consideração o peso e as dimensões da amostra. Após o recozimento, a amostra foi submetida aos testes adequados para evidenciar o tamanho dos grãos e sua influência nas propriedades magnéticas. Seus resultados mostraram um crescimento significativo no tamanho dos grãos após o recozimento secundário, e geração da textura goss, que é desejada ao material. Com as análises foi possível concluir que após o recozimento, os grãos apresentaram tamanhos padronizados e bem ordenados, e a padronização das perdas e permeabilidade magnética que respectivamente resultaram em 1,5 W/Kg e 1,99T nas condições de 1,7T a uma frequência de 60 Hz (frequência padrão brasileira).Research, Society and Development2019-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/73110.33448/rsd-v8i3.731Research, Society and Development; Vol. 8 No. 3; e3483731Research, Society and Development; Vol. 8 Núm. 3; e3483731Research, Society and Development; v. 8 n. 3; e34837312525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/731/719Copyright (c) 2019 Jefferson Rodrigo Lopes de Araújo, Herica Freitas Silva, Alex Bruno Caetano dos Reis, Michelle Bitencourtinfo:eu-repo/semantics/openAccessAraújo, Jefferson Rodrigo Lopes deSilva, Herica FreitasReis, Alex Bruno Caetano dosBitencourt, Michelle2020-03-25T16:07:05Zoai:ojs.pkp.sfu.ca:article/731Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:26:04.082347Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
