Abstract
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 is provided. An alternating current is run through an electromagnetic coil arranged around a casting mold so as to surround a casting space to control the meniscus shape to improve the cast slab surface properties. The discharge ports of a submerged entry nozzle are oriented upward and the direction of the discharge flow from the discharge ports is above the intersection of the casting mold short side and meniscus.
