Abstract

The physical-chemical study of the melting process both in cupolas and in electric furnaces has been carried out by the author. A methodology has been developed and a thermodynamic analysis of phase interaction during cast iron melting has been conducted which allowed making a comparative quantitative assessment of the influence of different factors on the processes of phase interaction. The authors have developed a method for determining the activities of the components in iron-carbon melts, being far from the diluted carbon content solutions, based not only on the consideration of the temperature dependences, but also on the concentration dependences of the interaction parameters. Technical and economic aspects of technical re-equipment of melting compartments in foundries have been analyzed.
