Abstract: The effect of Al2Ocylinder spinning thread speed on Al2Q inclusion dissolution velocity in refining slag - 4-10 MgO, 34-39 Al2O3), 33 ~ 42 CaO, 3 ~ 9 CaF2, 8 SiQ2 , 1.3 - 8.7 SrO and the dissolution velocity constant of Al2O3 in slag have been tested and studied by modified viscosity testing device. The results showed that to decrease the viscosity of refining slag and initial Al2O3 content in slag were favourable to increase the Al2Oabsorbability of refining slag.
