本文叙述了电弧炉电磁搅拌的功能和工作原理,详细地说明了电磁搅拌器的特征,分析了移动磁场的产生以及确定移动方向的分析法和现场实测法。介绍了电磁搅拌在冶炼过程中使用的原则。 我国第一台大型水冷电磁搅拌装置在40吨电弧炉上投入运行已多年。现根据部分冶炼记录列举出使用电磁搅拌后,在脱硫、合金成分控制、温度均匀以及产品质量和经济效益方面所得到的数据和效果。
This paper describes the function and working principle of EAF electromagnetic stirring, explains the characteristics of the electromagnetic stirrer in detail, analyzes the generation of moving magnetic field and the analysis method and field measurement method to determine the moving direction. Introduced the electromagnetic stirring principle used in the smelting process. China’s first large-scale water-cooled electromagnetic stirring device put into operation in 40 tons electric arc furnace for many years. Now based on part of the smelting record lists the use of electromagnetic stirring, the desulfurization, alloy composition control, temperature uniformity and product quality and economic benefits obtained by the data and results.
