Exploration of Preparation and Dezincification Percentage of Metallic Pellets from Sintering Electric Remove Dust

In order to reduce the waste of sintering resources,sintering electric removal dust is explored to make metallic pellets with better metallurgical performances by adding certain appropriations of mill scale,activated carbon,bentonite and organic binder.Compressive strength and the dezincification percentage of the pellets of each group were examined after the raw pellets were preheated and baked.It is found out that compressive strength first increases and then decreases with increasing carbon amount into pellets.When the carbon content is 1%~4%,the dezincification percentage of the pellets keeps constant （47%）,but the dezincification percentage decreases at 5% carbon content. With 3% addition of activated carbon into sintering electric removal dust,i metallic pellets can be obtained with better metallurgical performances and low Zn content.
