A tapping process model of the steel from the basic oxygen furnace (BOF) addressing the reactions in the ladle is proposed. In the model, the effective equilibrium reaction zone (EERZ) method is applied to describe the steel/slag interfacial reaction. The equilibrium reactions in the bulk steel (steel/inclusion/lining wear) and slag (liquid slag/slag additions/lining wear) are considered. The thermodynamic library—ChemApp is used to perform thermodynamic calculation. The process model includes most of the actions during the tapping process, such as the additions of ferroalloys and slag formers, carryover slag entrapment and air pick-up. After the calibration by the industrial measurements of two plants, the model is applied to study the influence of the amount of carryover slag.

提出了来自碱性氧气炉（BOF）的钢的出钢工艺模型，用于处理钢包中的反应。在模型中，采用有效平衡反应区（EERZ）方法来描述钢/渣界面反应。考虑了散装钢（钢/夹杂物/炉衬磨损）和炉渣（液态炉渣/炉渣添加量/炉衬磨损）的平衡反应。热力学库ChemApp用于执行热力学计算。该过程模型包括出钢过程中的大多数动作，例如添加铁合金和成渣剂，夹带残渣和吸气。通过两家工厂的工业测量结果进行校准后，该模型将用于研究残留炉渣量的影响。
