For this, the fluxes of varying constituents have been studied and with the help of proposed model, departure from the predicted value is studied. A validation exercise was performed with the help of developed agglomerated fluxes. The MnO, CaF2, MgO, NiO and Fe-Cr constituents of developed agglomerated fluxes added into the main constituents CaO, Sio2 and Al2o3,were chosen as variables to study the performance in terms of penetration. It was concluded that the model for prediction of penetration value for the specified range was in close proximity with the actual results obtained.
