Abstract Scope |
Different amounts of calcium wire were added to the molten steel during refining process in industrial trials to the effect of T.Ca contents on the size distribution, content, and morphology of inclusions. Thermodynamic calculations were also conducted to study the effect of T.Ca contents in inclusions. It was found that with the increasing of T.Ca content in steel, Al2O3 content in inclusions decreased while CaS content increased. However, when T.Ca content was bigger than 30 ppm, the CaO content decreased slightly and the CaS content increased more. As the T.Ca content in steel increased, the average size and area fraction of inclusions decreased, which means that appropriate calcium treatment technology will not reduce the cleanliness of molten steel and as well as will not increase the proportion of large-sized inclusions in steel. |
