“…1,2) Their existence destroys the uniform continuity of the steel matrix and has adverse effects on the mechanical properties and process properties of the steel. 3) Therefore, people have been researching and developing technology for the cleanliness of steel and the removal of inclusions. However, due to the details of the actual steelmaking operation and the influence of the removal kinetics of the product, some conventional removal methods such as electromagnetic stirring, [4][5][6][7] gas agitation, 8,9) slag washing, 10,11) filtration, 12,13) et al are difficult to achieve ultimate removal for those nonmetallic inclusions in very small size and uniformly distributed.…”

The super-gravity technique was used to remove the SiO 2 composite inclusions from 304 stainless steel. The effects of different super-gravity coefficients and super-gravity treatment time on the removal effect of inclusions were studied. It was found that the SiO 2-based composite inclusions floated up to the top of the sample after the super-gravity treatment, and the inclusions in the lower part of the sample were largely removed. The volume fraction and number density of inclusions presented a gradient distribution along the direction of the super-gravity, which became steeper with increasing gravity coefficient and treatment time. The total oxygen content at the bottom of the sample was reduced from 150 ppm to 93 ppm within 15 min of super-gravity treatment under the gravity coefficient of G = 80.
