VICTOR GEANTA, RADU STEFAOIU, IONELIA VOICULESCU EXPERIMENTAL RESEARCHES ON THE GRAPHITE PARTICLES DISSOLUTION DURING INJECTION PROCESS IN FERROUS METALLIC MELTS
The paper aims to present the experimental researches regarding dissolution phenomena of graphite powder particles during the injection process into ferrous metallic melts. The mass transfer was analyzed and specific calculation was performed for practical determination of dissolution time for graphite particles with different dimensions in melts with different chemical compositions varied from the carbon content point of view, based on injected material characteristics. In the paper are also presented the alloying process efficiency by injection for different metallic melts function of chemical composition, injected powder quantity and its characteristics.
Keywords: dissolution time, injection, alloying, chemical composition, mass transfer, efficiency
