In recent years,with the wide application of image data visual extraction technology in the field of industrial engineering,the development of industrial economy has reached a new *** explore the interaction between the pellet microstructure and compressive strength,firstly,the pellet microstructure needed for the experiment was obtained using a Leica DM4500P *** area proportions of hematite,calcium ferrite,magnetite,calcium silicate and pore in pellet microstructure were extracted by visual extraction technology of image ***,the relationship between the area proportions of mineral components and compressive strength was established by backpropagation neural network(BPNN),generalized regression neural network(grnn)and beetle antennae search-generalized regression neural network(bas-grnn)algorithms,which proves that the pellet microstructure can be used as the prediction standard of compressive *** errors of BPNN and bas-grnn are 5.13%and 3.37%,respectively,both of which are less than 5.5%.Therefore,through data visualization,we are able to discuss the connection between various components of pellet microstructure and compressive strength and provide new research ideas for improving the compressive strength and metallurgical performance of pellet.
