| 取向硅钢作为一种重要的铁芯材料，在电力行业中有着广泛的应用。基于生产工艺及技术特点，取向硅钢的制备工艺可以分为传统厚板坯工艺、薄板坯连铸连轧工艺及双辊薄带连铸工艺。传统的厚板坯工艺是工业生产取向硅钢的主要方法，其按加热温度又可分为板坯高温加热、板坯中温加热以及板坯低温加热工艺，其中板坯低温加热工艺具有加热温度低、能耗少、生产成本低等优点，是目前工业生产高磁感取向硅钢的主流技术。根据取向硅钢的发展历史，对取向硅钢的制备工艺进行了较为全面的综述。较为详细地概述了传统板坯高温加热、中温加热和低温加热工艺制备取向硅钢的成分体系以及工艺特点，重点综述了板坯低温渗氮工艺，并对取向硅钢的发展趋势进行了展望。 |

| As an important iron core material, grain-oriented silicon steel is widely used in power industry. Based on the process and technical characteristics, the preparation process of grain-oriented silicon steel can be divided into traditional thick slab process, thin slab continuous casting, rolling process and twin roll strip casting process. The traditional thick slab process is the main method for industrial production of grain-oriented silicon steel at present, which can be divided into slab high-temperature heating, slab medium temperature heating and slab low-temperature heating according to the heating temperature. And slab low-temperature heating has the advantages of low heating temperature, low energy consumption, and low production cost and is currently the mainstream technology for industrial production of high magnetic permeability grain-oriented silicon steel. According to the development of grain-oriented silicon steel, the preparation process of grain-oriented silicon steel was comprehensively reviewed. The composition system and process characteristics of grain-oriented silicon steel prepared by traditional slab high temperature heating, medium temperature heating and low temperature heating were summarized in detail, focusing on the slab low temperature nitriding process. Finally, the development trend of grain-oriented silicon steel is prospected. |
