Abstract
Influences of carbon and magnesia additions to CaO-base flux on the desulfurization behavior of liquid iron were investigated by using a Tamman electric furnace under N₂ gas atmosphere at 1350℃. The effects of either graphite or powdered coke on the behavior of desulfurization were found to be the same in this condition. The degree of desulfurization was improved with the addition of 10% MaO at the hard gas blowing, whereas decreased at the soft gas blowing, and also decreased with the addition of MgO over 10% under the gas flowrate of 1ℓ/min. On the other hand, the rate of desulfurization under this experimental conditions was found to be a first order reaction.
