Producing Iron Nuggets with Steel Making Wastes

A new process to recycle the iron and carbon from steel making wastes is proposed in this paper. We produce iron nuggets at high temperature by direct reduction with basic synthetic steel making wastes briquette or pellet has been introduced, in which the main factors of effecting iron nuggets separating from slag have been researched. The 2CaO·SiO₂ of slag changed phase, increased volume and natural pulverized in reduction process. Finally we obtain no-slag nuggets through screen separation. The iron in the nuggets is above 91%, the sulfur content is below 0.04%, and the carbon content is about 4.0%. The nuggets we get can be used as prime material for electric steelmaking and converter.
