本文开发了一个普适的顶吹转炉内金属液滴的产生、运动及传热的数学模型，在对炉内气体的流动、燃烧及传热研究的基础之上，引进液滴产生的分布函数，用概率模拟的Ｍｏｎｔｅ－Ｃａｒｌｏ方法模拟了液滴的随机产生（尺寸、位置及初速度），在Ｌａｎｇｒａｎｇｉａｎ的框架下跟踪了液滴的运动，计算了液滴的传热及温度变化，最后对所有液滴进行统计，给出了一些有实际意义的物理量（平均停留时间、平均传热量、平均上升最大高度等）的统计平均值。应用该模型计算了１８０ｔ转炉内液滴的产生、运动及传热情况，结果表明液滴在转炉内二次燃烧过程的传热中是一种重要的传热方式 In this paper, a universal mathematic model of metal droplet generation, movement and heat transfer in a top-blown converter was developed. Based on the study of gas flow, combustion and heat transfer in the furnace, the distribution function , The Monte-Carlo method of probability simulation was used to simulate the random generation of droplets (size, position and initial velocity), the movement of the droplets was tracked under the framework of Langrangian, and the heat transfer and temperature change of the droplets were calculated. Finally, All droplets are counted and statistical mean values ​​of some physically significant quantities (average residence time, average heat transfer, average rise height, etc.) are given. The model was used to calculate the droplet generation, movement and heat transfer in the 180t converter. The results show that the droplet is an important heat transfer method in the heat transfer of the secondary combustion in the converter
