Ladle deoxidation of liquid steel is done at 1600°C by adding ferro-aluminium. By assuming Stokes law behaviour, time (in s) required for alumina particles of 50 μm diameter to float to the surface from a depth of 2 m would be [Given: density of steel = 7000 kg/m 3 , density of alumina = 3650 kg/m 3 , viscosity of steel = 6 × 10 -3 kg/m/s]
