Abstract

Twenty-five numbers of blast furnace slag samples are collected from different operational Indian blast furnaces. The viscosities of these slag samples are estimated using various models developed by several researchers for the purpose. Subsequently, viscosities of some selected slag samples are measured using a high temperature viscometer to choose the best possible model that can be used in the present investigation. On the basis of the results, a comparison is made between the various models bringing about the shortcomings of these mathematical models. It is observed that the estimated viscosities by Iida model are best fitted with the viscosities of slags measured by high temperature viscometer and hence, the viscosity data obtained by Iida model are analyzed at length to ascertain the compositional dependence of slag viscosity. It is observed that the industrial blast furnace slag viscosity is greatly influenced by its CaO/SiO2 ratio, MgO and Al2O3 contents.

Notes

  1. To avoid the measurement difficulties, the viscosities of some selected slag samples are measured experimentally. The selection is made based on the slag composition pertaining to C/S ratio.
