| Abstract: | The theoretical analysis and commercial experiment of desulfuration of ladle furnace for the refining of ultra-low sulfur steels are carried out in this paper,the results are: optimizing the composition of slag,increasing the optical basicity,deeply deoxidizing of both molten steel and slag;determining the proper slag weight are the effective methods of increasing the sulfur removal percentage.the average sulfur removal percentage of LF process in WuHan steel is 55%;the Iso-sulfur partial ratio charts in slag system of CaO-SiO2-Al2O3-MgO(5%)can instruct workers to determine the proper composition of slag. |
| Keywords: | desulfuration optical basicity sulfide capacity sulfur distribution ratio ultra-low sulfur steel |
