我国无取向电工钢技术的进步与发展

Progress and development of non-oriented electrical steel technology in China

改革开放以来,我国无取向电工钢技术进步为钢铁、电工行业发展及国民经济增长做出了重要贡献。从无取向电工钢生产的全流程进行分析,结合生产技术、装备升级,系统阐述了冶炼、热轧、冷轧、热处理、涂层等关键工序的生产工艺进步;从织构控制、磁性能提升、硅钢强化技术等角度,深入分析了支撑生产工艺进步的相关材料学技术机理;围绕“高效、高端、绿色、智能”的发展目标,描绘了无取向硅钢的技术发展趋势。我国无取向电工钢已形成技术创新—产品进步—技术机理研究互相支撑的良好发展格局,预期未来我国无取向电工钢的技术水平和产品实物质量将继续呈现引领全球的发展态势。

Since the reform and opening up,the technological progress of non-oriented electrical steel in China has made important contributions to the development of the steel and electrical industries,as well as to the growth of the national economy.The entire production process of non-oriented electrical steel is analyzed,and the production process progress of key processes such as smelting,hot rolling,cold rolling,heat treatment,coating,etc.is systematically elaborated,combined with production technology and equipment upgrading.From the perspectives of texture control,magnetic performance enhancement,and silicon steel strengthening technology,a thorough analysis is conducted on the relevant material science and technology mechanisms that support the progress of production processes.The technological development trend of non-oriented silicon steel is described around the development goals of“high-efficiency,high-end,green,and intelligence”.Chinese non-oriented electrical steel has formed a good development pattern of mutual support between technological innovation,product progress,and technological mechanism research.It is expected that the technological level and product quality of Chinese non-oriented electrical steel will continue to lead the global development trend in the future.
