Fusion Behaviour of Synthetic Aluminothermic Ferro-chrome Slags

Abstract

Fusion behaviour of synthetic slags resembling those produced during Alumino-thermic reduction of chromite ore for production of Low-carbon ferro-chrome has been thoroughly discussed. The effect of fluxes like CaO, MgO and CaF2 on the measured values of the characteristic temperatures, which represent the fusion behaviour of a slag, has been experimentally determined and critically discussed. All the three fluxing constituents are found to decrease the characteristic temperatures. CaF(sub)2 is found to decrease the gap between the liquidus temperature and the temperature characterising the flow of the slag.
