A thorough understanding of the mechanical properties of the adhering layer of iron ore granules is necessary to optimize green bed permeability and improve sinter plant productivity. With this in mind, tablets simulating the granule adhering layer were manufactured using proportions of components in each size range based on Litster’s granulation model. Uniaxial compression tests and direct shear...
In this study, pilot-scale sinter pot tests under three granulation moisture conditions were conducted. Porous structures of the sampled sinter cakes were reconstructed by X-ray microtomography and CFD simulations were applied based on the real geometry. The pressure drop of serial subzones along the sinter bed including sintered zone, high-temperature zone and humidified zone were discussed by analyzing...
NOx emission of coke combustion in iron ore sintering was modeled by overall reaction rate equations of NOx formation and reduction. Incorporating into a previous sintering heat treatment model, overall NOx emission can be predicted and the simulated results were well agreed with four sinter pot tests under varying conditions which are similar to actual production. In sintering, NOx emission is significantly...
