Abstract
PURPOSE:To manufacture a product improving quality at good yield by arranging a metal-made thin cylinder as concentric circle at inner circumferential side of a metal-made thick cylinder, packing powder between both cylinders, closing after degassing this packing layer, heating and expanding, and induction- heating and hot-extruding. CONSTITUTION:The metal-made thin cylinder 2 is concentrically arranged on the inner circumferential side of the metal-made thick cylinder 1 to constitute a capsule and the powder 3 to be clad is packed into the capsule and after degassing the powder packed part, it is closed by a tube end shield plate 5 to constitute a billet 4. This billet 4 is heated at about 800-1,150 deg.C and immediately charged in the container 6 and a plug 7 is inserted in the axial direction and by deforming the thin cylinder 2, the inner diameter of the billet 4 is expanded and the powder packed layer is compressed. Next, the billet 4 is induction- heated at about 1,100-1,200 deg.C and hot-extruded and after making the whole powder packing layer compact without development of crack and breakage, the thin cylinder 2 and the tube end shield plate 5 are removed. By this method, the powder clad double tubes having good quality is manufactured at good yield.
