Abstract

Possibility of high efficiency desulfurization of hot metal by magnesium gas was suggested from 350 g scale experiments in previous reports.1–4) The present study proves the possibility on the basis of 30 kg 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%.
