一引言转炉炼钢数学模型的核心组成之一是脱碳模型,近几年来,随着转炉吹炼工艺的发展,国内外的转炉普遍采用了顶底复合吹炼技术,其主要特点就是通过加强熔池的搅拌,改善了转炉冶金反应的条件,特别是对贯穿于炼钢过程始终的脱碳反应,由于底吹气体促进了熔池中碳元素的传递,改善了脱碳反应的动力学条件,从而提高了脱碳效率,
I. INTRODUCTION One of the core components of BOF mathematical model is decarburization model. In recent years, along with the development of BOF blowing process, converter at home and abroad has generally adopted the top and bottom compound blowing technology. Its main feature is through strengthening The stirring of the molten pool improves the metallurgical reaction conditions of the converter, especially for the decarburization reaction throughout the steelmaking process. The kinetic conditions of the decarburization reaction are improved because the bottom blowing gas promotes the carbon element transfer in the weld pool , Thus improving the decarburization efficiency,
