摘要

为得到更加合理的50 t中间包控流装置

通过建立几何相似比1∶4的单流中间包水模型

采用物理模拟试验

研究了不同流量(1.09、1.24 m

/h)、长水口插入深度(25、50、75 mm)、挡坝高度(90、135 mm)以及长水口和堰距离(190、390 mm)等参数对中间包流场的影响。模拟结果表明

当响应时间更小时

中间包死区体积反而更大;当中间包的平均停留时间越大时

中间包的死区体积越小;模型最优的中间包工艺参数为:控流方案8

、流量1.24 m

/h、长水口插入深度25 mm

其平均停留时间为294.99 s

死区体积百分数为16.05%。SPHD钢50 t中间包应用表明

采用流量40 m

长水口插入深度100 mm

挡坝高度540 mm

钢水夹杂物总量2.51 mg/10 kg

去除夹杂物明显。

Abstract

In order to obtain a more reasonable 50 t tundish flow control device

a single flow tundish water model with a geometrical similarity ratio of 1:4 is established

and physical simulation tests are carried out to study the effects of different flow rates ( 1.09 and 1.24 m

/h )

long nozzle insertion depth(25

50 and 75 mm )

retaining dam height ( 90 and 135 mm )and the distance between long nozzle and weir(190 and 390 mm )on the flow field in tundish. The simulation results show that when the response time is smaller

the dead zone volume of the tundish is larger. The larger the average residence time

the smaller the dead zone volume in tundish. The optimal tundish process parameters of model are： flow control scheme 8

flow rate 1. 24 m

long nozz

le insertion depth 25 mm

the average residence time is 294. 99 s

the percentage of dead zone volume is 16. 05%. SPHD steel 50 t tundish production application shows that by using flow 40 m

long nozzle inserted depth 100 mm

dam height 540 mm

the inclusion amount in steel is 2. 51 mg/10 kg

removing inclusion obviously.
