FTSC薄板坯連鑄中間包內流場及夾雜物運動軌跡的數值模擬

Mathematical simulation of steel flow and trajectory of inclusions in FTSC tundish

摘要: 以FTSC雙效沖擊板加單壩結構的中間包為研究對象,應用FLUENT軟件計算了中間包的三維流場、溫度場、夾雜物運動軌跡及不同尺寸夾雜物的排除率.結果表明,FTSC中間包內的雙效沖擊板和單壩能夠明顯改善鋼液的流動狀態和溫度分布,顯著提高夾雜物的排除率,并且對小尺寸夾雜物(d<60μm)排除率的影響尤為顯著.

Abstract: The three-dimensional flow field, temperature distribution, trajectory of inclusions, and removing rate of inclusions in a FTSC tundish were simulated by software FLUENT. The results showed that the flow control devices of double effect pad and dam in the FTSC tundish had a significant influence on improving the flow field and temperature distribution and on increasing the removing rate of inclusions especially small inclusions (d<60μm).
