Mathematical Simulation on the Influence of Melting Rate and Melting Current on Droplet Behavior During Electroslag Remelting Process

摘要

A transient three-dimensional model was established and calculated by the commercial software ANSYS Fluent 14.0 to simulate the electroslag remelting process. Based on this model, a quantitative analysis of droplet behavior during dripping process was conducted by monitoring the mass flow rate of steel phase on monitor surfaces to investigate the influence of melting rate and current on the equivalent diameter, dripping frequency, and dripping time of droplets. Results showed that the droplet size was proportional to the melting rate and the dripping frequency was proportional to the cubic root of the melting rate, while the droplet size was proportional to the melting current and the dripping frequency was inversely proportional to the melting current.
