The invention discloses a method for efficiently using powdery semicoke as sintering fuel during sintering production. The fuel energy using rate is increased when the powdery semicoke replaces traditional fuel such as coke powder to be used for sintering. The quality and metallurgical performance of sinter are improved. The method mainly includes the steps that when the powdery semicoke is used as the sintering fuel, a gradual fuel adding process is adopted, and efficient utilization of the powdery semicoke used as the sintering fuel is achieved by improving the granularity of the powdery semicoke and adjusting sintering parameters (the water content and return mine proportion of a mixture). The method is advantageous in that the cost of the sinter is reduced by reducing the cost of the sintering fuel, so that cost decreasing and benefit increasing are achieved for an iron and steel enterprise, and the using approach of the powdery semicoke in the ironmaking field is broadened. The powdery semicoke with the low-sulfur characteristic is used for sintering production, so that the emission of sulfur dioxide is reduced in the sintering process, and the national requirements for energy saving and emission reduction of the iron and steel industry are met.
