Title:
BLAST FURNACE BURDEN TRAJECTORY MODEL CONSTRUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/070691
Kind Code:
A1
Abstract:
A blast furnace burden trajectory model construction method, comprising: modeling a blast furnace burden descending process to obtain an initial furnace burden trajectory model formula; acquiring real material surface shape data; according to the real material surface shape data and the simulated material surface shape data, optimizing the model parameters in the initial furnace burden trajectory model formula by means of a genetic algorithm to compare the error value of the optimal individuals; and if the error value is less than the previous minimum error, updating the parameters in the furnace burden trajectory model formula by using the parameters of chromosomes of the individual. According to the method, the modeling process is simple, and the accuracy of the model is improved.
