Influence of slag viscosity and composition on the inclusion content in the steel is studied using laboratory experiments and modeling simulations. The steel samples are taken during the experimental process to record the inclusion content change. Afterwards the prepared samples are analyzed using automated scanning electron microscope and energy dispersive spectroscopy (SEM/EDS) method. A simple steel/slag reaction model is constructed based on the effective equilibrium reaction zone (EERZ) method. The inclusion content evolution process is discussed by combining the experimental and calculated results. It is found that the inclusion content evolution in the steel is determined by the inclusion generation and removal.

使用实验室实验和建模模拟研究了炉渣粘度和成分对钢中夹杂物含量的影响。在实验过程中取出钢样品以记录夹杂物含量变化。然后使用自动扫描电子显微镜和能量色散光谱 (SEM / EDS) 方法分析制备的样品。基于有效平衡反应区（EERZ）方法构建了一个简单的钢/渣反应模型。结合实验和计算结果讨论了夹杂物含量的演变过程。发现钢中夹杂物含量的演变是由夹杂物的产生和去除决定的。
