以异型坯连铸中间包为研究对象,采用FLUENT软件模拟研究了长水口浸入深度对中间包内钢液流动特性的影响。结果表明,随着长水口浸入深度的增加,中间包死区及活塞区体积有减小趋势,而混合区体积则相反;此外长水口浸入深度对中间包内夹杂物去除率有一定影响。 Taking the taper continuous casting tundish as the research object, the influence of the depth of the water inlet on the flow characteristics of the molten steel in the tundish was simulated by using FLUENT software. The results show that the volume of the dead zone and the piston zone of the tundish tends to decrease with the increase of the immersion depth of the watertight, while the volume of the mixing zone is opposite. In addition, the penetration depth of the tundish has some influence on the inclusion removal rate in the tundish.
