一、前言为测试冶金渣的热力学参数,有关专家做了大量的研究工作,提出了钢渣物化行为的理论模型。但是,由于熔渣的变化过程复杂,所以,迄今为止尚无一种有效的方式能简明地描述任何一种熔渣的热力学特性。应用物理化学原理阐明与炼钢过程有关的钢一渣和气一渣之间反应的最大障碍之一是缺乏氧化铁活度方面的知识。许多研究人员从成分范围极大的各种渣中测出了氧化铁-石灰-二氧化硅三元系中氧化铁的同分异构活度曲线,这种三元系是冶金过程中最有名的一种渣系。但是,研究者们在同分异构活度曲线图 I. Preface In order to test the thermodynamic parameters of metallurgical slag, a lot of experts have done a lot of research and put forward the theoretical model of the physical and chemical behavior of steel slag. However, there is no effective way to describe the thermodynamic properties of any kind of slag in a concise manner because of the complicated process of changing the slag. Applying the principles of physical chemistry One of the biggest obstacles in elucidating the reaction between steel slag and gas-slag in relation to the steel-making process is the lack of knowledge about the activity of iron oxide. Many researchers have measured the isomerization activity of iron oxide in the iron oxide-lime-silica trioxide system from a wide range of ingredients of very large composition, the ternary system being the most well-known in the metallurgical process A kind of slag system. However, researchers are working on the isomer activity graph
