摘要
为了提高6流方坯中间包冶金效果,通过中间包水力学模拟试验,研究了导流挡板中导流孔参数对中间包流场特征的影响,并对其进行极差分析,最终确定了导流挡板各参数影响中间包流场特征的主次顺序为:导流孔孔径>倾角>高度。并以此为指导思想,结合CFD数值仿真对导流挡板进行设计。设计方案为:3个导流孔直径分别为93、72、36 mm,位置分别为(220 mm,140 mm)、(350 mm,280 mm)、(700 mm,300 mm),倾斜角度分别为(21°,15°)、(8°,23°)、(10°,28°)。工业试验表明,设置该导流挡板装置可以有效改善钢液流动特性,提高中间包冶金效果。
In order to improve metallurgy effect of sixstrand billet tundish, the hydraulic simulation experiments are conducted to investigate the effects of the guide holes parameters on flow field characteristics in sixstrand billet tundish in the Metallurgy Engineering Technology Center of University of Science and Technology Liaoning. And the range analysis is conducted on them. Finally it is determined that the affecting factors are diameter, height and leanangle of the guide holes. The affecting level for flow field characteristics in tundish is： diameter〉lean-angles〉height. Using it as the guiding ideology the guide baffles are designed by CFD numerical simulation and the diameters of three guide holes are determined to be 93 mm,72 mm and 36 mm, positions, （220 mm,140 mm）,（350 mm,280 mm） and （700 mm,300 mm） and leanangle, （21°,15°）,（8°,23°） and （10°,28°） respectively. Industrial experiments indicate that installation of the guide baffles in the tundish will effectively improve the characteristics of molten steel flow and increase the effect of tundish metallurgy.
