1.前言近年来,钢包喷吹冶金成为迅速发展的炉外精炼技术。由于要求在短的规定时间完成脱氧、脱硫、合金化、夹杂形态控制、熔池均匀化等一系列过程,研究钢包中的流动、混合、传热、传质等宏观动力学因素是十分重要的。Gosman、Spalding提出了湍流循环流动数学模型。Szekely 等计算了不同冶金装置中的速度场,湍流动能分布及传热,传质过程。中西、Lehner、肖泽强、Helle等对各种冶金装置中混合时间与搅
1. Introduction In recent years, ladle metallurgy has become a rapidly developing furnace refining technology. It is very important to study the macroscopic kinetic factors such as flow, mixing, heat transfer and mass transfer in the ladle because it is required to complete a series of processes such as deoxidation, desulfurization, alloying, inclusion morphology control and homogenization of molten pool in a short time. . Gosman, Spalding proposed a turbulent circulation flow mathematical model. Szekely et al. Calculated the velocity field, turbulent kinetic energy distribution and heat and mass transfer processes in different metallurgical units.
