摘要
以某钢厂三流T形中间包为原型,通过常温水模实验,采用中间包配置U形控流装置方法,研究U形挡墙及导流孔的不同组合对中间包流场的优化效果。实验结果表明方案Ⅳ为最优方案:平均停留时间为546～680 s,死区体积分数为21%～35.2%,相邻水口响应时间极差小于5 s。
A hydraulic model trial in room temperature was built based on 3-stand T type ttmdish in one Steelmaking plant. It was used to study effect of optimum flow field in the tundish by means of contrasted different programs which compounded appropriate partition wall and the size of tundish hole. The result shows the program 4 is the best program. The average residence time in the modified tundish reached to 546 -680 s, the dead volume is 21%-35.2%. Different response time of near nozzles was no more than 5seconds.
