To alleviate macrosegregation, it is the first time that an electromagnetic nozzle swirling flow is applied with a mold electromagnetic stirrer (M-EMS) during continuous casting of square and round billets. Compared with those by only M-EMS, the carbon ranges in square and round billets can be reduced to 0.022 and 0.046 pct, respectively, and the equiaxed crystal ratios are 18 and 33 pct, respectively, by using opposite nozzle swirling flow.

新型电磁喷嘴旋流与电磁搅拌相结合的连铸宏观组织和偏析的实验研究

为了减轻宏观偏析，这是在方坯和圆坯的连续铸造过程中，第一次使用模具电磁搅拌器（M-EMS）施加电磁喷嘴旋流。与仅使用M-EMS的情况相比，通过使用相反的喷嘴旋流，可将方坯和圆形坯料中的碳范围分别降低至0.022和0.046 pct，等轴晶比分别为18和33 pct。
