摘要

采用水力学数理模拟的方法，研究了不同尺寸和安装位置的控流装置对马钢薄板坯连铸中间包流动特性的影响。结果表明：中间包在无流动控制时，存在明显的短路流及较大死区；西马克公司提供的控流装置其平均停留时间小，死区较大，实验效果并非最佳；改进后的优化方案使中间包内示踪剂开始响应时间为无控流装置下的2倍多，平均停留时间由264.0s 增加到301.4 s

死区由无控流装置的25.54%降低到 15.39%

中间包的冶金性能有了明显改进。

Abstract

The effect of flow control devices with different size and installed location on fluid flow in a thin slab conca-sting tundish at Maanshan Iron and Steel has been investigated by physical and mathematical hydraulics- simulation. The re- sults showed that as tundish hadn't flow control devices there were a short flow and a big dead zone volume; and with using the flow control devices provided by SMS

the applying result wasn't optimum due to short average residence time and bigger dead zone volume; and with using the improved optimized flow control devices

the onset response time was more than two times as long as that without using flow control devices

the average residence time increased to 301.4s from 264.0s

and the dead zone volume decreased to 15.39% from 25.54% obviously to improved the metallurgical capability.
