Abstract
Since 1970s of last century, the electroslag remelting (ESR) process began to be used in the production of cold roll steel, which led to an obvious improvement in chemical homogeneity, cleanliness and compact microstructure. The properties of cold roll steel have been significantly improved. ESR process is invisible, most previous researches focused on temperature field, concentration field and velocity field of ESR by establishing mathematical model and using Fluent software. The influence of process parameters on ESR, based on commercial software Melt-Flow and Cr5 cold roll, was studied in this paper. Results showed that increasing electrode filling ratio could reduce molten pool depth and local solidification time, and this could also play a role in energy conservation; With the increase of slag pool depth, molten pool became shallower, but local solidification time increased; A greater melting rate led to the increase of molten pool depth and local solidification time.
