Abstract

Experimental and theoretical studies were made to clarify the effect of raw burden properties, such as high temperature properties, so called KS, and JIS-RI of sinter and the slag rate in blast furnace, on permeability in blast furnace with an experimental blast furnace operation and a 3-dimensional blast furnace mathematical model.
Obtained results are summarized as follows:
(1) By analyzing the experimental blast furnace operation using the sinter of low SiO2 contents, it was shown that KS of sinter was more effective on permeability in the experimental blast furnace than slag rate.
(2) By modeling of permeability evaluation of cohesive-zone based on KS, it was also confirmed that KS of sinter was more effective on permeability in the actual blast furnace than slag rate.
