<p>In this research, a numerical model has been built to investigate the molten steel flow and inclusion distribution with feeding oscillatory and bilateral strips. The results show that feeding oscillatory strip compresses ipsilateral lower recirculation. Simultaneously, it expands ipsilateral unformed-recirculation flow and contralateral lower recirculation, while feeding bilateral strips compresses both lower recirculation and makes flow pattern more symmetrical. Strip oscillation makes the motion of inclusions near strip more inclined to downward and bilateral feeding offers a larger strip feeding ratio, causing inclusions to gather toward center by both feeding methods from the slab thickness perspective. Moreover, the smaller feeding depth and expanded lower recirculation on non-feeding side caused by strip oscillation promotes the inclusion motion from sides to slab center. The more symmetrical lower recirculation generated by bilateral strip feeding prevents inclusions from moving toward the inclusion enrichment zones on both sides. Consequently, these two methods of strip feeding both promote inclusions to move toward slab center. Based on the statistics results, feeding oscillatory strip increases the inclusion proportion in slab central zone by 0.25 pct, while feeding bilateral strips increases it by 2.45 pct.</p>
