The invention belongs to the field of blast furnace cooling systems, and particularly relates to a computer calibration method of the cooling effect of a blast furnace cooling system. The computer calibration method of the cooling effect of the blast furnace cooling system is suitable for judging the excellence of the cooling capacity of the blast furnace cooling system. According to the computercalibration method of the cooling effect of the blast furnace cooling system, the cooling effect of the blast furnace cooling system is calibrated by adopting the cooling intensity or the cooling efficiency of a blast furnace, wherein the cooling intensity is calculated by the temperature ratio of a hot surface temperature of a cooling wall under ideal conditions to a hot surface temperature of the cooling wall under actual conditions; and the higher the temperature ratio, the better the cooling effect of the blast furnace cooling system. The computer calibration method of the cooling effect of the blast furnace cooling system directly aims at the physical quantity which can embody the essential cooling capacity of the cooling system, namely the hot surface temperature of the cooling wall,the hot surface temperature of the cooling wall is taken as a research object, and the computer calibration method of the cooling effect of the blast furnace cooling system is simple and clear and has great practical significance. A unified standard is established for quantitative comparison and analysis of cooling capacity of different blast furnace cooling systems in the future, and a solid foundation is laid for further analysis of cooling capacity of the blast furnace cooling system in the future.
