PURPOSE: A dephosphorization method is provided to dephosphorize the molten iron of a converter and to recycle slag by inputting sintered ores with time intervals. CONSTITUTION: A dephosphorization method is as follows: a step of measuring the initial temperature of molten iron and the content of silicon(S10); a step of inputting 0.5-0.7% of sintered ores with regard to the molten iron at a preset first time after a dephosphorization converter starts dephosporizing and blowing(S20); a step of repeatedly inputting a set amount of the sintered ores depending on the initial temperature of the molten iron and the content of the silicon until a second time(S30); and a step of finishing a blowing process at a time when the inputted sintered ores are dissolved(S40). [Reference numerals] (AA) Start; (BB) End; (S10) Measuring the initial temperature of molten iron and the content of silicon; (S20) Inputting a predetermined amount of sintered ores at a preset first time after starting dephosporizing and blowing; (S30) Repeatedly inputting a set amount of the sintered ores depending on the initial temperature of the molten iron and the content of the silicon until a second time; (S40) Finishing the blowing process at a time when the inputted sintered ores are molten; |
