摘要

Scale layer can be formed on the slab surface in the areas of secondary cooling and strand discharge during continuous casting process. From 1000°C-1200°C, the influence of steel composition on the stable oxide phases inside scale layer, particularly the types of alloying elements including aluminum, silicon and chromium, is investigated under different partial pressures of water vapor by the calculated predominance diagrams of iron oxide as well as its intermediate compounds formed with other metal oxides, and the stable oxide phase composition within scale layer under the working condition of secondary cooling is discussed. At lower partial pressure of water vapor, only a iron spinel (or ferrosilicate) phase is the stable phase with any alloying element contents in steel composition, whereas the stable phases are FeO and iron spinel (or ferrosilicate) inside the scale layer at higher partial pressures of water vapor.
