摘要
Possibility of high efficiency desulfurization of hot metal by magnesium gas was suggested from 350g scale experiments in previous reports. (1-4)) The present study proves the possibility on the basis of 30kg scale experiments. Conbination of dilution of magnesium gas by argon gas and use of the injector which has 6 narrow exit holes allows to obtain magnesium efficiency of 74 % at a quantity of magnesium of 0.2 kg per ton hot metal at the initial sulfur content of 0.02 mass%.
