Title
Effect of silicon Addition on the Desulfurization Rate of liquid Steel by Lime Injection
갑경환Gyung Hwan Shin, 이형철Hyoung Chul Lee, 백영현Young Hyun Paik
Abstract
Desulfurization of molten steel was carried out in a high frequency induction furnace at temperatures between 1550℃ and 1705℃. Rates of desulfurization by CaO powder injection with Ar-gas were measured with varying the amount of silicon added, the initial sulfur content, and the temperature, respectively. Results showed that the desulfurization rate was increased with increasing the amount of silicon and also the temperature. Rate equation for desulfurization was developed to be the 1st order with respect to dissolved sulfur content and also the reaction mechanism was proposed. The apparent activation energy of the reaction was found to be about 40.7㎉/mole.
