Dephosphorization of molten carbon saturated iron with CaO-FeCl2 flux was investigated in a laboratory scale test.
By using CaO-FeCl2 flux of 100 kg/t, 90% dephosphorization is possible together with desulphurization of 8090% when the molten carbon saturated iron has silicon, manganese and chromium content less than 0.05%, respectively.
In a graphite crucible test, dephosphorization of 60% is achieved even when molten carbon saturated iron has 1618% chromium content.
The dephosphorization with CaO-FeCl2 flux is considered to be due to oxidation with (FeO) which is formed by the reaction between CaO and FeCl2. This is similar to the results obtained using CaO-CaCl2 FeO flux.
