单流中间包挡墙对夹杂物去除速率的影响
|
摘要
优化中间包结构去除钢液夹杂物是一项重要工作。本文建立某厂单流中间包的夹杂物去除的数学模型,计算不同挡墙高度及入口、出口位置对中间包内夹杂物去除的影响。结论表明:夹杂物去除速率最高时,下挡墙高为318 mm,上挡墙距钢包底部距离为532 mm,上下挡墙距离为600 mm,上挡墙距钢包入口距离为800 mm。
Optimizing tundish structure to remove inclusions from molten steel is an important work. In the present work,a mathematical model was established for simulating removing inclusions from molten steel in single-strand tundish in a steelworks. Influences of different baffle wall heights and inlet and outlet positions on the inclusion removal rate in the tundish were calculated. It was concluded that the highest inclusion removal rate was achieved with the lower baffle wall height being 318 mm,the distance between the upper baffle wall and the tundish bottom being 532 mm,the vertical distance between the upper and the lower baffle walls being 600 mm,and the distance between the upper baffle wall and the tundish inlet being 800 mm.
