The effect of an electric field with different polarities on the inner wall of a submerged entry nozzle made of rare earth steel was investigated. The results show that the electric field induces a change in the decarburization, erosion, and clogging processes of the nozzle. In the casting of rare earth steel, the negative electric field affects the decarburization, erosion, and clogging of the nozzle. Moreover, when a reverse positive electric field is applied on the wall of the submerged entry nozzle, these processes can be effectively reduced. This ensures the integrity of the submerged entry nozzle and its smooth production during the continuous casting process.

外部电场对稀土钢浸入式喷嘴壁的影响

研究了不同极性的电场对由稀土钢制成的浸入式水口的内壁的影响。结果表明，电场会引起喷嘴的脱碳，腐蚀和堵塞过程发生变化。在稀土钢的铸造中，负电场会影响喷嘴的脱碳，腐蚀和堵塞。而且，当反向正电场施加在浸入式喷嘴的壁上时，可以有效地减少这些过程。这样可以确保浸入式注嘴的完整性以及在连续铸造过程中的顺畅生产。
