摘要
以板坯连铸结晶器为研究对象,以fluent软件中磁流体力学模块MHD(Magneto-hydrodynamics)和离散相模块DPM(Discrete phase model)为平台,分别计算在拉速、电磁制动及吹氩作用下,结晶器内小气泡的分布情况。实验结果表明:在不同板坯拉速下,气泡受钢液流股冲击到达结晶器窄边位置;拉速越大,气泡越向边部聚集;在施加电磁制动的情况下比未施加电磁制动时气泡数量总体降低。
In this study,through slab continuous casting mold as research object,fluent software module MHD（ Magneto- hydrodynamics） and DPM（ Discrete phase model） as platform,distribution of small bubbles under the condition of different casting speeds,electromagnetic brake and argon flow rates is studied. The results show that： under the different slab casting speeds,bubbles were easily reached the narrow side accompanying with the liquid steel and with the casting speed increases,more bubbles would gather in the narrow side. Besides that,in the case of applying electromagnetic brake,the amount of bubbles decreased significantly.
