Abstract
In this study, the wastes were used as fuels for direct reduction iron (DRI) production to reduce production cost and recycle the wastes. We examined the effects of wastes on the reduction behavior of DRI manufacture and the possibility of using wastes as auxiliary fuels. The proximate and Ultimate analysis were carried out to confirm the properties of wastes as fuels, and high-quality reduced irons were fabricated by using the waste as an auxiliary fuel. The metallization of reduced irons increased as the calorific value increase of auxiliary fuel. Especially, the reduced irons fabricated from the waste tires and vinyl plastics which had high heat energy and volatile matters showed higher metallization than the others. The high calorific value and volatility of waste were significant properties as fuel. The high quality DRI could be fabricated with wastes as auxiliary fuels through optimization of reaction conditions.
