THE EFFECTIVENESS OF DEPHOSPHORIZATION WITH AND WITHOUT FLUORSPAR USING IN THE ELECTRIC ARC FURNACE STEELMAKING
Abstract
This article deals with comparison of parameters from two different technologies – one with fluorspar and another one without fluorspar using. Fluorspar is being eliminated due to its toxicity and negative environmental impact. The statistical evaluation of 60 campaigns of electric arc furnace plant was performed. According to the graphical relationships and average values of parameters, it was found that chemical compositions of slags did not change practically and high effective dephosphorization can be achieved without fluorspar too. The negative influence of fluorspar using on the refractory lining and also negative influence of rising temperature on the phosphorus removal were confirmed.
