The invention discloses a blast furnace tuyere service life management method and device and a storage medium. The blast furnace tuyere service life management method comprises the following steps that 1, blast furnace upper material distribution system data, tuyere system data, tuyere replacement data and cooling system data are collected every day; 2, a utilization coefficient is calculated according to the daily yield in the upper material distribution system data and the actual furnace volume of a blast furnace; 3, the average service life of a tuyere is calculated in the preset time according to the tuyere replacement data; and 4, the blast furnace is operated according to the upper material distribution system data, the tuyere system data and the cooling system data when the utilization coefficient is greater than a first preset value and the average service life is greater than a second preset value. By implementing the method, the quantitative relationship among the yield, the tuyere life and a blast furnace operation system is established, and the production stability of the blast furnace and the stability of slag crust are ensured by reasonably controlling a material distribution system, an air supply system and a tuyere cooling system, so that the service life of the tuyere is essentially prolonged on the basis of ensuring the yield of the blast furnace.
Description
technical field [0001] The invention relates to the technical field of blast furnace smelting, in particular to a method, device and storage medium for managing the service life of a tuyere of a blast furnace. Background technique [0002] The blast furnace tuyere is located in the blast furnace, and its environment is very harsh. It has to withstand the high-temperature scour of high-temperature hot air, the impact and scour of slag iron and high-speed circulating hot materials (mainly coke blocks); the outer surface of the tuyere has to withstand The high-temperature radiant airflow and the convective heat transfer of slag and iron; the wall of the tuyere has to bear the thermal stress caused by the temperature difference between the inside and the outside; When charging, the tuyere will also be hit by the lumpy charge. Therefore, the tuyere is one of the vulnerable parts of the blast furnace. [0003] At the same time, the damage of the tuyere has a great impact on the ...
