| Abstract Scope |
This REMADE project is looking at methods to overcome the barriers that currently limit the use of recycled steel (as recovered from scrap streams) in new steel products. Currently, the use of recycled steel is limited due to contaminants that downgrade the value of the steel by limiting the range of products in which the recycled steel may be used. These limitations are due to technical gaps that are addressed in this exploratory project.
(1). The inability to identify and sort steel scrap from auto shredders, in an automated way: The composition of two bulk auto shredder steel scrap samples have been evaluated to determine the amount of copper (Cu) that end up in secondary steel that passes onward to steel production. Two new potential methods for sorting the scrap to reject impurities have been identified. Preliminary experimental results are presented.
(2). The inability to efficiently separate Cu from steel scrap from auto shredders using post-shredder technologies: Two methods have been identified and will be evaluated on a lab scale. These experiments are intended to asses metallurgical ways of removing the impurities, downstream, either in the solid or the molten state. |
