ABSTRACT:
A method of recycling metallic coated scrap pieces wherein the coating layer liquidus temperature is lower than the core layer solidus temperature, such as brazing sheet scrap pieces, or metallic coated scrap pieces wherein the upper part of the melting range of the coating layer overlaps the lower part of the melting range of the core layer, by at least partially removing the coating layer from the core layer of the scrap pieces making use of a heat resistant metallurgical vessel having an opening for introducing the scrap pieces into the vessel and an exit for discharging essentially molten alloy. The vessel being rotatable around an axis of rotation.
