Method For Manufacturing Grain-Oriented Silicon Steel Containing High Silicon By Strip Casting Process

摘要

The invention may relates to a method of manufacturing a grain-oriented electrical steel sheet used for a generator or a transformer iron core, the addition of Si By producing a grain-oriented electrical steel sheet in an appropriate condition with a vertical ssangrol strip casting process to 5.5%, do not add to the C to provide a method for manufacturing a high silicon grain-oriented electrical steel by strip casting process, which can omit the decarburization step, it will have the purpose.; The present invention relates to a method of producing a strip casting process using high silicon grain-oriented electrical steel sheet, by wt%, C: 0.003% or less, and Si: the silicon steel melt containing 2.0~5.5% in an atmosphere of nitrogen 20~30 ℃ overheating of the melt road casting a strip with a thickness of 2.0mm or less, and brush pickling, the surface of the strip (brushing), and then, second, including intermediate annealing stage by using the cold rolling after the cold rolling to a thickness of less than 0.3mm this 1100 - 1200 ℃ in 10 - by the strip casting process for producing the high temperature heat treatment and 20 hours to a method of manufacturing a silicon grain-oriented electrical steel sheet as a base.
