Embodiment

[0017] A kind of preparation method of H type molybdenum wire, described preparation method comprises the following steps:

[0018] Select a molybdenum rod with a unit weight of 25kg and a diameter of φ8.0mm, and obtain a molybdenum rod of φ3.3mm through an electric furnace heating and stringing process, and obtain a molybdenum rod of φ0.85mm through an electric furnace heating single-mode turntable stretching process, and then perform an annealing process; Finally, the 0.183 molybdenum wire is obtained through a multi-mode drawing process, and then the finished product is packaged.

[0019] As a further optimization of this scheme, the electric furnace heating stringing process includes one three-mode stringing and two three-mode stringing; the one-time three-mode stringing processes φ8.0mm to φ6.8±0.1mm, φ5 .8±0.1mm, φ5.0±0.1mm; the two times of three-mode serial printing process φ5.0±0.1mm to φ4.3mm, φ3.7mm, φ3.3mm.

[0020] As a further optimization of this scheme, the el...

Abstract

The invention discloses a preparation method of an H-type molybdenum wire. The preparation method comprises the steps of selecting a rolled molybdenum rod with the single weight of 25 kg and the diameter of 8.0 mm; obtaining a molybdenum rod with the diameter of 3.3 mm through an electric furnace heating tandem beating process; obtaining a molybdenum rod with the diameter of 0.85 mm through an electric furnace heating single-mold turntable drawing process, and then carrying out an annealing process; and finally obtaining a molybdenum wire with the diameter of 0.183 mm through a multi-mold drawing process, and then packaging the finished product. According to the preparation method of the H-type molybdenum wire, the produced molybdenum wire has the advantages of high strength, small extension, high wear resistance, high current cutting resistance and the like.

Description

technical field [0001] The invention relates to the technical field of molybdenum wire preparation methods, in particular to a preparation method of H-shaped molybdenum wire. Background technique [0002] Molybdenum wire mainly refers to a consumable material made of precious metals such as molybdenum that moves continuously with a high-voltage electric field to cut workpieces during wire cutting. It is called electrode), which can perform pulse spark discharge erosion and cutting metal forming on the workpiece. However, the molybdenum wire produced by the processing of the prior art has defects such as low strength, large elongation, and low wear resistance. Contents of the invention [0003] (1) Solved technical problems [0004] The invention discloses a method for preparing an H-shaped molybdenum wire, so that the produced molybdenum wire has the advantages of high strength, small elongation, high wear resistance, high current cutting resistance, and the like. [00...
