Definitions
- the exterior UNITED STATES PATENTS of the product may consist of a corrosion-resistant metal (or alloy), whilst the core may be a low alloy 3,167,857 2/1965 Sarto et al.
- the present invention relates to the preparation of a compound wire, i.e. a metal wire consisting of an interior core and an outer cover. having properties not known before.
- a high scaling resistance is often required of a wire which is used at a high temperature, for instance, on conveyors through furnaces, as resistor elements, etc.
- ferritic stainless steels or Cr-Ni-alloys which are brittle and expensive and, hence, not ideal.
- a wire material which consists of an inner core of one metal with an outer cover or plating thereon of a different metal.
- the cover should then preferably be attached to a core of a wire blank or billet, after which this composite blank is worked to the finished wire by means of known methods, such as hot and cold rolling, drawing, extrusion and the like. It is of course ofthe greatest importance that a complete adhesion be obtained between the core and the cover and that this adhesion be maintained throughout the whole working of the wire blank to the finished wire. This earlier had cause difficulties which are eliminated by means of the method of the present invention.
- the present invention relates to a method for the preparation of compound wire of metal and is characterized in that a core of a metallic wire blank or billet is surrounded by a tubular mantle of a different metal and is joined to the latter by means of explosive joining or cladding, after which the wire blank further is worked to the finished wire by means of known methods.
- the core material in the finished wire consists of a rolled or forged metallic core or of a wire rolling blank, prepared in some other way, and that the metallic material of the cover or mantle consists of a seamless or welded tube or a plate bent to a tubular shape.
- the composite billet is worked to wire or bar having a diameter of 3-20 mm, preferably 5-15 mm, by means of a hot rolling operation or in some other known manner. Further working can be carried out by means of cold rolling, drawing, extrusion or other known methods.
- a compound wire consisting of a core of one metal with a well adhering mantle of a selected different metallic starting material.
- the mantle layer is continuous and free from holes or cracks.
- the mantle is securely joined to the core, throughout the surface area of the core, by explosive joining by the procedure described in US. Pat. No. 3,397,444.
- the finished compound wire can be shaped to round wire or to narrow bands (flat wire) with a straight edge or with a varying edge radius, using known methods.
- the mantle of the material can consist of an austenitic stainless steel, a nickel alloy, titanium or titanium alloy or of another corrosionresistant material, while the material of the core consists of an unalloyed or low-alloy carbon steel. If the wire is to be used for the preparation of springs, the core material should consist of a spring steel. Compound wires thus prepared are also suitable for the production of corrosion-resistant wire cables.
- the material of the core preferably consists of a ductile steel or of another ductile alloy, while the material of the mantle consists of a ferritic stainless steel, a nickel-chromium alloy or of another alloy characterized by a high resistance to scaling.
- the material of the mantle correspondingly consists of a steel or another material with a high abrasion resistance.
- a roller wire blank of carbon steel containing 0.85 percent C and with a diameter of 101 mm was explosion plated with a tube of stainless steel of the 18-8 type.
- the tube had an interior diameter of 107 mm and the thickness of the material was 3 mm.
- the composite billet was rolled to 5.5 mm wire and then drawn, by means of conventional wire drawing technique, to a diameter of 1.9 mm. in all phases from billet to the finished wire the material was controlled and the adhesion between the core and the mantle was found to be excellent.
- Compound wire of the diameter 3.8 mm was oilhardened by continuous austenitizing, quenching in oil and annealing in a lead bath, and compression springs were prepared from the hardened wire.
- the compound wire was shaped to springs with fully acceptable values as to straightness, length and pitch.
- core and mantle materials which mainly consists of steel and steel alloys. It is. however, obvious to the expert that the invention is not restricted to the use of merely these materials but that also other metallic materials can be fully used in the present process.
- a process for preparation of a compound metal wire which comprises surrounding a core of a wire billet with a tubular mantle, joining mantle and billet by means of explosive joining or cladding and working the resulting composite wire billet to finished wire.
