Foaming parameters such as foaming ratio and foaming index were determined. It was found that with increase of the basicity of slags, the foaming ratio increased, however, the foaming index was opposite. In addition, the effects of additives like MgO, Na_2O and CaF_2 on the foaming behaviour were also investigated. The result of dimensional analysis showed that the foaming index(∑) of molten slag was determined by where μ is the viscosity of the slag,σis the surface tension, ρis the density of the slag and g is the acceleration of gravity.
