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. CaF₂ is found to decrease the gap between the liquidus temperature and the temperature characterising the flow of the slag.
