【 摘 要 】

This work examined phosphorus enrichment in different micro areas of the earlier slag and the final slag in converter double-slag technology. The results show that: phosphorus has high enrichment in the micro-area the basictity of which is between 2 to 2,5; the phosphorus content is at a higher point in the micro area with a silicon (Si) content of 9 % ~ 12 % in the final slag or 13 % ~ 14 % in the earlier slag; phosphorus can reach the maximum value when the ferrum content is between 5 % ~ 9 %, higher phosphorus content appears in the micro zone with a low magnesium content.
