• Combustion behavior of granulated coke breeze in iron

    2018-12-1 · 1. Introduction. Iron ore sintering is a very important process which produces sinter as a major burden for blast furnace ironmaking. In this process, iron ore and auxiliary materials, e.g., fluxes, unqualified sinter (called return fine), and coke breeze, are mixed, granulated and then sintered at high temperatures.Effect of the catalyzing combustion of coke breeze on the,The mechanism of additive ZC-1 for catalyzing combustion of coke breeze in sintering of iron ore fines was studied by using X-ray Diffraction, TGA and GC(Gas Chromatographer), by which energy saving was achieved on sinter pot test. The results show that the distance between cleavage planes is enlarged and the π-electrons are re-distributed because of the insertion of
