A method and apparatus for producing a dense metal strip from a green compacted powder strip making use of a chamber (10) with a gaseous atmosphere at a sub-atmospheric pressure suitable for operating a glow discharge electron beam heating device and in which the strip (12) is passed continuously through heating means (14-18) comprising one or more such devices, and then passed through a rolling mill (20, 22) within the chamber to effect further compaction. The rolling mill (20, 22) preferably comprises two or more stages (20, 22) with intermediate reheating means (21) and the compacted strip may be coiled on a spool (25) within the chamber. |
