| 摘 要： | 以安钢宽板坯连铸为研究对象,采用大型商业软件ANSYSCFX10.0,应用VOF法重点研究浸入式水口倾角、拉速、铸坯断面宽度等工艺参数对结晶器内自由表面液面波动的影响.结果表明:随着结晶器宽度从1800mm增大到3250mm,结晶器内液面平均波高明显降低.当宽度为1800mm时,结晶器保护渣-钢液界面平均波高为5.33mm;当宽度增至3250mm时,平均波高为7.08mm.

| Abstract: | The effect of the angle of submerged entry nozzles, casting speed, and cross-section width of slabs on the surface fluctuation in a mold of Anyang Iron & Steel was researched with the VOF model of commercial software ANSYS CFX10.0. The results show that with the mold width increasing from 1 800 mm to 3 250 mm, the average wave height of liquid level in the mold decreases significantly. When the width is 1 800 mm, the average wave height of the mold flux-molten steel interface is 5.33 mm; when the width is 3 250 mm. the average wave height is 7.08 mm. |
