post combustion of converter is a kind of thermal compensation technique aiming at an incr-ease in scrap ratio. The sub-nozzles of the lance of post combustion are of straight shape, and atan angle of 30--40 degrees. On the basis of dry test of jet features, the industrial experiments ofapplication of lance of post combustion were performed in a 30-ton converter. The results showedthat when the proportion of the area of the sub-nozzles to total nozzle area of single flow lance is16.2-37.5%, the scrap ratio can be increased by 0.9-3.5%. When the percentage of post combustionis increased to approximate 8%, the calculated heat efficiency is about 74% This tecbnique is quitepractical, making smelting opertion stable and without any harmful effect on the various technlogi-cal and economic parameters of the converter.
