摘　　要：对原型、U型和Y型挡墙中间包温度场进行了数值模拟。模拟结果表明:原型中间包挡墙形式不合理,中部和边部水口的温差较大;U型挡墙中间包温度场虽较原型有一定程度的改善,但也存在一定的问题;Y型挡墙中间包较原型和U型温度场分布更加均匀,温降更小,是较合理的挡墙形式。The original, U and Y types of blocking wall are numerically simulated in this paper. Three conclusions are drawn from the results： the original-type is unreasonable, temperature difference between mid-outlet and side - outlet is large. U-type blocking wall causes better temperature field, however, it still has some weakness. Y-type blocking wall reaches better temperature field and less temperature decrease, and is the reasonable form of blocking wall in tundish.
