Kinetic Analysis of Compositional Changes in Inclusions during Ladle Refining

Abstract: It is well known that the composition of inclusions is determined by alloying elements and by reaction with slag. For example, MgO·Al2O3 spinel-type inclusions form, even though Mg is not added, due to the supply of Mg through the reaction between slag and metal. To clarify the mechanism of compositional changes in inclusions, the authors have developed a kinetic model to simulate the reactions during the ladle refining process. In this study, experiments were conducted using an induction furnace, and the comp… Show more

“…The CR model was also adopted by the Tohoku University Research Group (TURG). Harada et al [107,108,109,306] developed an LF model focusing on the prediction of the inclusion composition. The bulk of the idea is quite similar to that of MURG.…”

“…The CaO-Al 2 O 3 inclusion is occasionally observed during the secondary refining of Al-killed steel. [1][2][3][4][5][6][7][8] Todoroki et al 1) studied the change in composition of the inclusions in Al-killed 18%Cr-8%Ni stainless steel through a reaction with the top slag of a CaO-Al 2 O 3 -MgO-F system. They found that alumina or MgO•Al 2 O 3 spinel inclusions were formed immediately after the addition of Al.…”

“…[2][3][4][5][6][7] However, because the equilibrium relation with Ca and oxygen differs widely in individual studies, [9][10][11][12][13][14] the most stable oxide in steel containing a small concentration of Ca (few ppm) remains unclear. Harada et al 8)…”

“…Verma N. et al [5] e Harada A. et al [6], relatam em seus estudos que inclusões de espinélio formam-se no aço líquido principalmente pela reação entre o aço e a escória na panela (mais do que pela reação entre o aço e refratário). Esta conclusão é suportada pelas seguintes observações: o conteúdo de óxido de magnésio nas inclusões aumenta em paralelo com o pickup de silício no aço (o pickup de silício ocorre pela reação entre aço e escória da panela); nenhuma diferença na formação de espinélio foi encontrada no aço contido em panelas totalmente revestidas com tijolos MgO e reações entre aços acalmados ao aluminio num cadinho de MgO (em experimentos de laboratório) geram espinélios como produto, porém partículas de espinélios permanecem na interface aço-MgO e não entram no aço líquido [5].…”
