The invention discloses a smelting method for facilitating converter scrap steel melting with gasification dephosphorization slag. The method includes the specific steps that the dosage of a carbon-containing agent is 50-100kg/t slag when a slag-splashing protection converter is subjected to gasification dephosphorization, the converter is shaken after slag splashing, 10t-25t of scrap steel is added, the converter is shaken front and back for several times, and thus the scrap steel and the slag can be basically mixed; then a converter body is shaken vertically, an oxygen lance is lowered for blowing oxygen, the oxygen blowing time is 1-2 minutes, the oxygen lance position is controlled to be 0.5-0.7m hard blowing, the oxygen can be quickly reacted with the carbon-containing agent in the slag for releasing heat, the oxygen lance is lifted to a normal position after the scrap steel temperature is raised, the converter is shaken, and molten iron is added for conventional converter smelting; and the converter scrap steel ratio reaches 15%-19% after smelting, and the utilization rate of the carbon-containing agent is larger than or equal to 80%. By the adoption of the smelting method, the reaction heat release effect of excessive carbon in the gasification dephosphorization slag is given into full play, and fast fusion of the scrap steel after the molten iron is accelerated. The converter scrap steel ratio is increased, the amount of converter slag discharged outwards is reduced, slag iron losses are reduced and the metal yield is increased.
