摘要

This paper has investigated a new desulfurizer for iron and steel industry to make up the lackness of magnesium-based desulfurizer. In order to explore the desulfurization process of hot metal by the new desulfurizer, both the thermodynamics and experiments have been studied.. The results of thermodynamics indicated that, under the standard condition, the lowest reaction temperatures of MgO + C and MgO +Si were 1846℃ and 2132℃ and the pressure of Mg vapor at the hot metal temperature were 0.2-0.5kPa and 0.0050.01kPa, respectively. In the case of reaction between MgO and Al, the calculated starting reaction temperature under standard condition was 1475℃, and the pressure of Mg vapor was distributed from 27 kPa to 45kPa at the hot metal temperature, showing that it was easy to happen the reaction of MgO+Al. The experimental results displayed that the desulfurization efficiency was only 42.31% by the desulfurizer of MgO and C, while the effect of MgO+ Al and MgO+ Al-Si was good, since the desulfurization efficiencies were above 85%, and the lowest sulfur content was below 40×10-6.
