Influence of basicity on thermal properties and mineralogical structure of pellets

In view of poor thermal state metallurgical properties of acid pellets,by adding dolomite to adjust pellet basicity, the reduction disintegration index at low temperature and reduction swelling index of pellets with different basicity after I hour re- duction were studied,then the mineralogical structure of pellets was analyzed by optical microscope, and the relationship between pellet basicity and thermal metallurgical properties and mineralogical structure was obtained. It is expected that this wiU provide basis and reference for taking reasonable measures and improving product quality in pellet production.
