CONTINUOUS MANUFACTURE OF METALLIC PRODUCT

摘要

PURPOSE:To manufacture an extruded material having an uniform structure free from bubbles continuously and easily in pressing powdery fine metallic material to a wire-shaped body in a conduit formed by a driving wall face and a fixed wall face by pressing the material after heating and deaeration. CONSTITUTION:A conduit 6 is formed by the wall face 3 of a groove 2 of a driving wheel 1 and a fixed wall face 5 of a fixed block 4. Metallic powder 10 is supplied from a powder supplying device 7 continuously to the conduit 6 and sent to the rear end of the conduit 6. Extruding pressure is applied gradually and the powdery body is extruded from an extruding die 9 as a wire-shaped body 11. At this time, the powdery body 10 is heated to above 100 deg.C, preferably to 200-400 deg.C by a heater 12 in the supplying device 7 to gasify moisture etc. contained. Air, water vapor etc. existing in the powdery body 10 are sucked and excluded by the pipe 14 of a deaeration device 13 before the extrusion grip zone 7 where extruding force is increased.
