Abstract

The regularity and good working order of the blast furnace are determined by total control of the permeability of the burden. In this respect, size analysis of the coke constitutes an essential factor. New information concerning its behavior in the blast furnace has been deduced from direct observations using blast furnace dissections and probes. In this perspective, probing equipment through the tuyeres has recently been installed at SOLMER with the collaboration of IRSID. The coke is subjected to intense granulometric degradation between the throat and the tuyeres. This deterioration cannot be entirely predicted by conventional cold testing techniques; in fact, it also depends on the thermal and chemical history of the coke in the blast furnace, as well as the stress to which it is subjected.
