The invention relates to a method for recycling nickel during production of high-nickel steel through a converter. The method comprises the steps that firstly, when the converter produces high-nickelsteel, a one-casting-time steel grade with the requirement for the nickel content is arranged; secondly, high-nickel steel smelting is finished, and nitrogen is adopted for slag splashing; thirdly, smelting is conducted in a complete slag remaining manner; fourthly, the small-flow slow mixing manner is adopted during iron mixing; fifthly, the slag melt is reserved for high-nickel steel, the gun position is kept at 2.4-2.8 m, 25-30kg/t steel of lime and 15-20 kg/t steel of light-roasted dolomite are added, the final temperature is controlled to range from 1,680 DEG C to 1,690 DEG C, and the final carbon content is controlled to range from 0.04% to 0.06%; and sixthly, a molten steel tank containing the molten high-nickel steel is used for producing the melt with the requirement for the nickel content, argon bottom blowing is conducted in the whole tapping process, a nickel plate is supplemented according to test components after tapping, and the nickel content is controlled within the finished product range. By means of the method, residual nickel generated during high-nickel steel production can be comprehensively recycled, the production cost is reduced, and it is guaranteed that converter newly-smelted molten steel components are not polluted.
