In order to meet the strict requirements of low- phosphorus steels,a suitable process was invented by Xichang Vanadium & Steel to smelt low-phosphorus high quality steels with semi-steel.By optimizing the oxygen lance of converter smelting process,selecting reasonable combined blowing and slag making schemes,and controlling end-point smelting temperature at about 1 620℃,the end-point phosphorus content was stably reduced from 0.013% to 0.006%,satisfying the requirements of high quality steels on dephosphorization.
