Problems solved by technology

Hot drawing has disadvantages such as high production cost, long production cycle, and large environmental pollution, but it is still the main production process of special alloys at present; cold drawing process has gradually emerged over the years, but there are also high equipment procurement costs, high employee work intensity, Product quality is difficult to control and other shortcomings
[0003] In order to solve the above production problems, especially the production technical problems of high production cost, difficult manufacturing and unstable quality of special alloys, especially the processing of special alloys with larger diameters (φ10.00) to smaller diameters (φ1.00 ) special alloy wire requires multiple production processes, the product surface is easy to scratch and break during processing, and oil mist pollution and dust pollution in the production process

Abstract

The invention discloses a novel special high-temperature alloy wire hot rolling process, and belongs to the technical field of wire processing. The process comprises the following steps that S1, a special high-temperature alloy bar is subjected to surface pretreatment, and a wire with the specification of phi 8.00-4.00 mm is formed through cold drawing; and S2, the wire obtained in step S1 is sequentially subjected to early-stage heating, middle-stage heating and later-stage heating treatment, then cold rolling is carried out multiple times, cooling is carried out in the cold rolling process, and after the wire is subjected to cold rolling to a certain specification, wire winding is carried out to obtain the novel special high-temperature alloy wire. The process provided by the invention is high in production efficiency, low in process control difficulty, excellent in product quality and low in manufacturing cost.

Description

Technical field [0001] The present invention belongs to the field of wire processing technology, and more particularly to a new type of special high temperature alloy wire material hot rolling process. Background technique [0002] When various metal wire bars, especially high-tensile strength, high-hardness special alloy ribs, mainly mainly in traditional hot tiles and cold drawing process in recent years. The hot tiles have a high production cost, long production cycle, and a large amount of environmental pollution, but this is still the main production process of special alloys; the cold drawing process has gradually emerged, but there is also high equipment procurement cost, and the employee work strength, The product quality is difficult to control. [0003] In order to solve the above production challenge, especially the production cost of the special alloy, the production technology problem of manufacturing difficulty, quality is unstable, especially for large diameter (φ1...
