摘要

Based on the laboratory experiment of reducing iron ore-coal pellet in oxidizing atmo- sphere, a new self-heating reduction method of iron ore-coal pellet in the cocurrent shaft furnace (CSF) has been developed. In this process, the pellets and preheated oxygen-enriched air enter the shaft furnace through its top and descend cocurrently in the furnace. Most of the heat required for rising temperature and endothermic reduction of descending pellets is provided by the way that the descending air burns the volatile from pellets and CO from the reduction of iron oxide in pellets.
