Pure nickel wire short-flow preparation process

Abstract

The invention belongs to the field of metal material machining, in particular to a pure nickel wire short-flow preparation process. The pure nickel wire short-flow preparation process comprises the steps of: 1) vacuum induction smelting; 2) surface polishing of round ingots; 3) heating of the round ingots: the heating temperature is 980-1050 DEG C; and the temperature is maintained by 0.5-1.0 hour; 4) cogging and hot rolling: the cogging is performed; and wire rods are rolled; and 5) drawing: wires are drawn. The pure nickel wire short-flow preparation process has the effects of few procedures, high efficiency, prominent reduction of the production cost, incapability of generating such defects as cracks, cold-lap, corners, steps and unevenness and guarantee of subsequent rolling of the wire rods and the wire quality performances.

Description

technical field [0001] The invention belongs to the field of metal material processing, and in particular relates to a short-flow preparation process of pure nickel wire. Background technique [0002] Pure nickel wire is mainly used to manufacture electron tube cathodes, anode grid side bars, tube needles, etc. Has good mechanical properties and corrosion resistance to alkalis, such as sodium hydroxide. It also has good electrical, thermal, and magnetic control characteristics. Applications include food and synthetic fiber processing, heat exchangers and chemical, power industries. Typical manufactures include resistance thermometers, internal parts of electronic tubes, such as grid side rods, struts, and external parts of electronic tubes, such as lead wires, etc. The existing production process of pure nickel wire: At present, the domestic production of pure nickel wire mainly adopts vacuum induction melting → ingot skinning → forging → grinding → rolling → drawing.

Problems solved by technology

The existing production process of pure nickel wire: At present, the domestic production of pure nickel wire mainly adopts vacuum induction melting → ingot skinning → forging → grinding → rolling → drawing. There are many production processes in this method. High cost and long product delivery cycle

During the forging process, the surface of the billet is prone to visible cracks, heavy skin, corners, steps, and uneven defects. In order to eliminate the above defects, the grinding process requires a series of grinding of the billet, which is prone to produce a large amount of metal dust. Defects require manual grinding, resulting in poor working conditions for workers, low production efficiency, and increased metal loss
