摘要: 本文以低碳低合金钢为例,考察了电渣重熔反应体系的总的化学行为,基于渗透理论和薄膜理论,提出了一个新的电渣重熔过程化学反应及传质模型。理论上说,该模型可适用于任何钢和合金的电渣重熔过程,可更精确地估算熔渣和金属两相内的成分变化。对该理论模型作了求解,讨论和确定了模型各参数。
Abstract:Precise control of chemical composition and uniform distribution of alloying elements are the requirements to obtain final products in high quality, Up to now, the problem of how to effectively control the changes in chemical composition and the redistribution of alloying elements during the remelting process is still not well resolved. The general problems introduced into the modelling of ESR chemical reac tions by virtue of the various reactions stoichiomctries are discussed. In particular it is described the difficulties in using simplified reaction schemes such as the Mn/FeO/Fe/MnO exchange as the basis for modelling systems in which as many as eight separate reactions may require simultaneous equilibrium solutions. Based upon the penetration and film theories, a scheme of describing such systems is developed. The new model, theoretically, may be applied to any ESR system, i. e. to the ESR process of any steels and alloys, and the changes in composition of both metal and slag phases may be more precisely predicted. The theoretical model has been solved. The parameters for the model are discussed and determined.
