In this paper, the sampling experiment during smelting process in the 100t converter of Chengde steel company was researched, and 21 heats all 2718 first-hand valuable process data was measured。According to statistical analysis on the data attained, the change of elements in molten bath had been described quantificationally. Based on the transformation of V-C during the smelting process, optional oxidation of extracting vanadium from converter was discussed. This study got the characteristics in extracting vanadium by 100t convert of Chengde steel company. Firstly, the changing curve of each element in molten bath had been given. Secondly, the activity coefficient of V2O3 in vanadium slag had been estimated about 2.1410-4. Thirdly, the changing curve on critical temperature of replacing vanadium with carbon had been given. Comparing the change of practical temperature in the molten bath of the converter, the smelting actuality was analyzed and advice was proposed.
