J. Jimenez et al., Burden distribution analysis by digital image processing in a scale model of a blast furnace shaft, ISIJ INT, 40(2), 2000, pp. 114-120
During the realigning of Aceralia's blast furnace B in Gijon, a 1/10 scale
half-section, three-dimensional cold model of the BF shaft was built to tes
t charging patterns and the effect of gas flow in burden distribution. The
front side of this half model is closed by a methacrylate sheet that allows
images of the burden distribution inside the model to be obtained, during
and after the charging process. image processing techniques were applied to
obtain useful information from burden profile images. A complete study of
a charging pattern is presented in this paper.
The model has allowed study of some local effects of gas flow in burden dis
tribution, such as changes in the final coke layer during ore charging, and
the formation of a narrow window in the centre of the model that connects
the successive coke layers.
