    • The present invention provides a continuous casting method of molten metal using electromagnetic force to improve the cast slab surface properties and reduce the nonmetallic inclusions and bubbles trapped inside the cast slab. An alternating current is run through an electromagnetic coil 4 arranged around a casting mold 1 so as to surround a casting space 8 to control the meniscus shape to improve the cast slab surface properties, the discharge ports 6 of a submerged entry nozzle 5 are made upward oriented, and the direction of the discharge flow 14 from the discharge ports 6 is made one to above the intersection A of the casting mold short side and meniscus. Due to this, the nonmetallic inclusions and bubbles in the discharge flow are absorbed by the continuous casting mold flux of the meniscus 11 at the part of the meniscus reached. Further, the discharge flow 14 receives electromagnetic force due to the electromagnetic coil 4 whereby the spread of the discharge flow in the cast slab thickness direction is suppressed and the discharge flow 14 does not contact the long side shell 12, so it is possible to keep nonmetallic inclusions and bubbles from being trapped from the discharge flow 14 at the long side shell 12.
    • 本发明提供一种使用电磁力的熔融金属的连续铸造方法,以改善铸坯表面性能并减少非铸造板坯内的非金属夹杂物和气泡。 交流电流穿过围绕铸模1布置的电磁线圈4,以围绕铸造空间8以控制弯月面形状以改善铸坯表面性能,使浸入式喷嘴5的排出口6向上 并且将排出口6的排出流路14的方向设置在铸模短边和弯液面的交点A之上。 由此,排出流中的非金属夹杂物和气泡被半月板部分的弯液面11的连续铸模熔剂吸收。 此外,排出流14受到电磁线圈4的电磁力的影响,能够抑制铸坯厚度方向的排出流的扩散,排出流14不与长边壳12接触,因此能够保持 非金属夹杂物和气泡被从长侧壳12的排出流14捕获。
