Nippon Steel In-Mold Electro-Magnetic Stirrer M-EMS for slab caster

Japanese industries have been loudly demanding steel manufacturers to provide a stable supply of high quality steel sheet/plates. In order to satisfy customer need, slab surfaces have to be scarfed in large quantities. As the technique to solve such problem, Nippon Steel developed In-Mold Electro-Magnetic Stirrer (or "M-EMS") for slab casters which can improve the surface quality of slabs. In this paper, the features and effects of this system are outlined.
