摘　　要：采用数值模拟技术模拟八机八流中间包内流场温度场,分析金属液流场在中间包内从入口至不同出口的钢液运动轨迹,讨论金属液流场和温度场对卷气、卷渣的影响。结果表明,中间包出入口之间温差最大相差4.1 K。在八机八流中间包内的3、6号出口携带气体和夹杂物。Flow field and temperature field in 8-Machine 8-Strand Tundish was simulated by the numerical simulation software. The molten steel motion trail of flow field in tundish from entrance to different exports was analyzed. The influences of liquid metal flow field and temperature field on the volume of gas and slag were discussed. The results show that the maximum temperature difference is 4.1 K in tundish from the entrance to the export. There are gas and inclusion at the export of No.3 and No.6 in 8-Machine 8-Strand Tundish.
