| 摘要 | For forming a compound wire, a core of a wire billet is enclosed within a tubular metallic mantle; the mantle is joined to the core by an explosive joining method; and the resulting composite is worked to a wire of the desired cross-sectional dimensions. Thus, the exterior of the product may consist of a corrosionresistant metal (or alloy), whilst the core may be a low alloy carbon steel. | ||||||
| 权利要求 | 1. 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. 2. The process of claim 1 for the preparation of a corrosion-resistant compound wire, in which the material of the core consists of an unalloyed or low-alloy carbon steel, and the material of the mantle consists of a corrosion-resistant material selected from the group consisting of an austenitic stainless steel, a nickel alloy, titanium and a titanium alloy. 3. The process of claim 1 for the preparation of compound wire having pronounced resistance to scaling at elevated temperatures, in which the material of the core consists of a ductile alloy and the material of the mantle consists of an alloy having a high resistance to scaling and selected from the group consisting of ferritic stainless steel and a nickel-chromium alloy. 4. The process of claim 1 for the preparation of a compound wire having a high abrasion resistance, in which the material of the core consists of ductile steel, and the material of the mantle consists of some other material having a high abrasion resistance. 5. The process of claim 1 wherein the composite wire billet after the explosive joining is hot-rolled in a known manner or is worked in a known manner to a wire or bar with a diameter of 3-20 mm, preferably 5-15 mm. |
