摘要

Pyrite cinder and high sulfur magnetite were used as raw materials to produce iron ore pellets.Good qualities of green balls and fired pellets were obtained from the feed comprising 50% pyrite cinder and 50% high sulfur magnetite concentrate at a small scale.Small-scale tests were proven by pilot-scale tests.The high grade fired pellets,assaying 63.22% Fe,were analyzed,and the compressive strength of fired pellets was over 2 500N/pellet.The fired pellets possessed excellent metallurgical performances,such as reducibility index higher than 67%,reduction swelling index lower than 15% and low temperature reduction degradation index (+3.15mm) higher than 1%,which can be used as the burden for blast furnace.
