Efficient numerical simulation method for hot blast stove process optimization

The invention belongs to the field of hot-blast stove parameter control in metallurgical engineering, and particularly relates to an efficient numerical simulation method for hot-blast stove process optimization, which comprises the following steps of: taking the average temperature and mass flow of high-temperature flue gas flowing into a regenerative chamber from the top in a combustion period calculated by a three-dimensional model as inlet boundary conditions of a two-dimensional model; and high-efficiency cyclic simulation on continuous multi-cycle operation of the hot blast stove is realized. Compared with the prior art, the method has the beneficial effects that accurate and reasonable visual reference is provided for the combustion, mixing and flowing states of gas in the hot blast stove in a specific operation period and the thermal saturation state of the checker bricks; and accurate guidance is provided for operation control and optimization of each operation period of the hot blast stove in a shor
