The efficiency of this desulphurizer and factors influencing its effects were emphatically analysed.The gists of the experiments process were as follows:the optimum control of top slag composition,forming the top slag in ladle early,the good deoxidation, increasing the Ar gas stiring strength.The experimental results showed that given the desulphurizers addition among 15~20 kg/t,the average LF process time is shorted 10 min,the average desulpherizing rate is raised 16%.
