Carrying out the comparative study on test method for determining the content of sulphur and different desulfurization processes,concrete measures for further adding more limes to increase the basicity in the slag are proposed in consideration of the existing desulfurization process.Based on the results for testing the compositions in the slag,it is concluded that the desulphurization efficiency by VD is restricted,and the desulphurization is operated mainly by LF acctully and therefore the deep desulphurization by LD-LF-CC can be achieved only if the desulphurization slag is ready.
