电磁搅拌能够有效地增加铸坯等轴晶率,减少铸坯中的夹杂物和中心偏析等缺陷,已经成为改善铸坯和成品质量的重要手段之一。回顾了电磁搅拌技术的发展,介绍了电磁搅拌的类型。根据安装位置不同,电磁搅拌分为结晶器、二冷区和凝固末端搅拌。每种电磁搅拌具有各自的特点和冶金效果,电磁搅拌参数影响电磁搅拌的冶金效果。选择合适的电磁搅拌器和电磁搅拌参数,能够提高电磁搅拌的冶金效果。
Electromagnetic stirring can effectively increase the billet equiaxed grain rate, reduce the inclusions in the slab and center segregation and other defects, has become an important means to improve the slab and finished product quality. Review the development of electromagnetic stirring technology, introduced the type of electromagnetic stirring. According to the different installation location, electromagnetic stirring is divided into mold, the second cooling zone and the end of the stirring coagulation. Each electromagnetic stirring has its own characteristics and metallurgical effects, electromagnetic stirring parameters affect the metallurgical effect of electromagnetic stirring. Select the appropriate electromagnetic stirrer and electromagnetic stirring parameters, to improve the metallurgical effect of electromagnetic stirring.
