Abstract

1388896 Extruding SWISS ALUMINIUM Ltd 17 March 1972 [18 March 1971] 12646/72 Heading B3P In a method of extruding metal, e.g. aluminium or alloys thereof, through a die assembly 16 the assembly is cooled by nitrogen supplied in a liquid phase and allowed to change to a gaseous phase as it enters a coolant channel 37 in the die assembly and to escape over the extruded metal to provide a protective atmosphere. The channel is formed in a die bolster 35 or in the walls of a die holder 33. Radial passages (38), Fig. 3 (not shown), in the die bolster 35 lead to outlets adjacent the downstream end of the die. The die is mounted on a slide 15 with a coolant passage (46), Fig. 4 (not shown), aligned with a coolant supply line (44) when the die is on the extrusion axis. The liquefied gas is supplied from a container 21 through a control valve 23, a safety valve 24 and a magnetic valve 25 operated by the press plunger or the extrusion pressure in the billet container 17 to ensure coolant supply only during extrusion. The extruded product may be rod or tube and is supported by a table 26.
