The transverse static magnetic field (TSMF) was introduced into the electroslag remelting (ESR) process to produce GCr15 steel ingots and the microstructure, non-metallic inclusions, chemical composition and mechanical properties of the ingots were analyzed to investigate the effect of TSMF during the ESR process. The transverse section of the ingots indicated that the application of a 130 mT static magnetic field resulted in a refined dendritic structure. The coverage ratio of the homogeneous crystallites area in the center of the transverse section increased to 52%. The metallic solid-liquid interface with different magnetic flux density (MFD) was recorded during ESR process. The depth of the metallic molten pool was 44.2 mm without the TSMF. When a 130 mT TSMF was applied, the molten pool became noticeably shallower (14.2 mm). And the oxide inclusions count in the scan area of 5.117 mm² decreased to 239 from 1212. When the TSMF implemented, the tensile, friction and wear and Rockwell hardness properties of ingots showed a significant improvement. These results showed that the application of TSMF during the ESR process of GCr15 steel not only refine the dendritic structure, but also improve the efficiency of inclusion removal and mechanical properties.

将横向静磁场（TSMF）引入电渣重熔（ESR）过程中，以生产GCr15钢锭，并分析了钢锭的显微组织，非金属夹杂物，化学成分和力学性能，以研究TSMF在钢锭中的作用。 ESR流程。铸锭的横截面表明，施加130 mT静磁场会产生细化的树枝状结构。横截面中心的均匀晶粒区域的覆盖率增加到52％。在ESR过程中记录了具有不同磁通密度（MFD）的金属固液界面。在没有TSMF的情况下，金属熔池的深度为44.2 mm。当使用130 mT TSMF时，熔池明显变浅（14.2 mm）。²从1212降低到239。当实施TSMF时，铸锭的拉伸，摩擦和磨损以及洛氏硬度特性得到了显着改善。这些结果表明，TSMF在GCr15钢的ESR工艺中的应用不仅改善了枝晶结构，而且提高了夹杂物去除效率和力学性能。
