Abstract

PURPOSE: To decrease the reduction rate of the sintered ores in the recuction area at low temperature and thus to prevent the pulverization phenomenon of the ores, by coating the substance which generates CaCO3 by absorbing CO2 in the air on the surface of the sintered ores and thus by forming the coating of CaCO3.
