“…In this calculation, the activities of Mg and Al were calculated using the concentration of each element and the activity coefficient. 7,8) The activity of O was calculated using the equilibrium relationship of Al and Al2O3. The activities of MgO, Al2O3, and MgO·Al2O3 were assumed to be unity.…”

“…Hino (17) Hino (17) Assim, embora parte das discrepâncias entre os resultados de equilíbrio de desoxidação possa ser reduzida quando se considera o efeito das interações entre os solutos no liquido, com será visto nas próximas seções, persiste uma incerteza considerável. A Figura 1 apresenta uma comparação das equações propostas para a solubilidade do MgO a 1600 o C nos três trabalhos mais confiáveis na literatura.…”

“…MgO•Al 2 O 3 inclusions subsequently form via reactions between Al or Al 2 O 3 inclusions with Mg or MgO. 3,4) Non-metallic inclusions can be effectively removed by facilitating collision, agglomeration, and coalescence of inclusions, to form coarse inclusions that are easily removed via flotation. 2,5) The agglomeration and coalescence of inclusions can be better controlled and estimated by understanding the wetting behavior between the inclusions and molten iron or steel, such as the interfacial energy and the contact angle.…”
