CHARACTERIZATION OF MOLD FLUXES FOR CONTINUOUS CASTING OF STEELS

摘要

During continuous casting of steel, the properties of mold fluxes strongly affect the casting performance, steel quality and environment of the casting operation. In this study, a high temperature microscopy technique was used to investigate the melting behaviour of mold fluxes, and a drip test method was used to determine their melting rate. The results showed that free carbon was a dominant factor in governing the melting behaviour of the fluxes, and the melting rate increased with increasing carbon reactivity and with decreasing carbon content.
