METHOD OF REMOVING A METALLIC COATING LAYER FROM SCRAP METAL PIECES |
摘要 |
<p>A metallic coating layer is removed at least partly from scrap metal pieces having a core and the coating layer on the core. The coating layer has a lower melting temperature than the core. The scrap metal pieces are agitated in a container with abrading elements so as to cause multiple collisions, whereby the coating layer is at least partly removed. During the agitating the container temperature is a temperature T in the range Ts(coat)<T<TL(core) wherein Ts(coat) is the solidus temperature of the coating layer and TL(core) is the liquidus temperature of the core. The agitation may be by rotationally tumbling or shaking the scrap metal pieces and the abrading elements.</p> |
