Περιγραφή

This division includes the activities of smelting and/or refining ferrous and non-ferrous metals from ore, pig, metal waste or scrap, using electro-metallurgic and other metallurgical process techniques. This division also includes the manufacture of metal alloys and super-alloys by introducing other chemical elements to pure metals. The output of smelting and refining, usually in ingot form, is used in rolling, drawing and extruding operations to make, for example, plate, sheet, strip, bars, rods, wire or tubes, pipes and hollow profiles and other basic metal products, and in molten form to make castings.
