摘要/Abstract

摘要： 通过计算流体力学软件FLUENT建立的数学模型对钢厂200 mm×1 600 mm铸坯二流T型23 t中间包现挡墙和坝、湍流控制器和坝、湍流控制器和现挡墙以及新挡墙4种结构方案进行三维数值模拟,研究原中间包及安装不同控流装置后的钢水流动特性。结果表明,在所有的设计方案中安装有湍流控制器和坝的中间包能够达到最佳优化效果;中间包的死区体积分率由30.18%降到16.51%,活塞流区与死区的体积分率比R_Vp/Vd由55.80%增大到129.44%;中间包内流动稳定,有利于夹杂物的上浮。

Abstract: Three dimensional numerical simulation on steel works 200 mm x 1600 mm casting slab two-strand T- shape 23 t tundish 4 kinds of structure scheme-present baffle wall and dam, turbulence inhibitor and dam, turbulence inhibitor and present baffle, wall as well as new baffle has been carried out by using calculation fluid dynamics software FLUENT to study liquid flow characteristics of original tundish and with installed different flow control devices. Results show that in all design schemes the tundish with installed turbulence inhibitor and dam has best optimum effect; the volume fraction of dead zone in tundish decreases from 30. 18% to 16. 51% , the volume fraction ratio of piston flow zone and dead zone- R_vp/vd increases from 55. 80% to 129.44% , the flow in tundish is stable to be available for inclusions in liquid floating up.
