Abstract
864,532. Powder metallurgy. COPPERWELD STEEL CO. June 24, 1957 [June 29, 1956], No. 19859/57. Class 82(1) [Also in Groups XXII and XXXVI] In a method of cladding a metal e.g. steel core a powdered metal having a lower melting point e.g. aluminium copper or mixtures largely of those metals is pressed on to the moving tensioned core, the cladcore then being rolled at a temperature below the melting point of the cladding metal to unite the metals without diffusion at the interface. The cladding metal has a lower tensile strength than the core metal and/or has a greater corrosion resistance. The composite rod wire or flat may be used for electrical conductors, fencing wire or concrete reinforcement. A steel core-rod 12, Fig. 1, drawn from a reel 11 is strengthened at 16 and cleaned at 17 by abrasion, a gas or a liquid before passing through a tube 20, Fig. 2, containing an aluminium powder 50 fed from a hopper 19 by a vibration-assisted gravity feed. The pressure rolls 24, Fig. 4, the peripheral speed of which is equal to that of the core 12 press the powder around the core and the clad-rod 12a is then inductively heated in a reducing atmosphere to a temperature between 950‹F. and 1180‹F. for from 1 to 10 minutes to plasticize the powder prior to passing the rod through rolls 24a which effect the bonding of the cladding to the core in a reducing atmosphere. No single pass of the rolls 24a reduces the rod by more than 10%. The clad-rod 12a may then be annealed prior to hot-reduction in a reducing atmosphere by rolls 24b. After hot-reduction the clad-rod 12a is cooled in a reducing atmosphere and then further reduced cold by rolls 24c with no single pass making a reduction exceeding 10% and annealing being carried out as required. The rod is then subsequently drawn down to its final diameter. In a modification the pressure-rolls, the induction heater and the bonding rolls are mounted so that the rod moves vertically, the clad-rod being subsequently further hot-reduced, by passing through further rolls, cooled and wound on a reel. When copper cladding is used the induction-heating range is 1800‹F. 1900‹F. and the hot-rolling reductions may be at 1600‹F.-1900‹F., annealing being carried out at 1300‹F.
