Problems solved by technology

However, existing nickel-plated wire rods also have some shortcomings such as poor product stability, easy peeling of the coating, and dull surface of the coating in actual use. The main reason is that the alloy layer formed by the nickel coating and the copper substrate is not uniform enough. Coating force of coating is not enough; In addition, with respect to the application of some industrial fields such as electronics industry and industries such as aerospace, railway with special requirements, the existing nickel-plated copper wire product is in the ductility of nickel coating, corrosion resistance, High temperature resistance, color change resistance, etc. also need to be further improved

Embodiment

[0044] The production process of the nickel-cerium alloy annealed copper wire of the present invention includes copper wire drawing, degreasing, water washing, pickling, pre-plating, electroplating, hot water washing, ultrasonic water washing, drying and taking-up, and quality inspection and warehousing in sequence. The conditions of each process are as follows.

[0045] 1. Copper wire drawing

[0046] The copper rod with a diameter of 8.00mm is first drawn to a diameter of 2.80mm to 3.00mm through a large drawing machine, and then drawn to a diameter of 0.40mm to 1.20mm through a middle drawing machine, and then annealed and induced in a bell-type annealing furnace After formula continuous annealing, a round copper wire with a diameter of 0.40 mm to 1.20 mm is obtained.

[0047] 2. Degreasing

[0048] During the drawing process of copper wire, lubricating oil will adhere to its surface. Oil stains on metal surfaces are almost unavoidable, mainly from cooling, lubrication, ...

Abstract

The invention relates to a technique for producing a nickelplated mischmetal annealed copper wire, which comprises the working procedures such as drawing copper wire, removing oil, washing, acid cleaning, preplating, electroplating, hot water rinsing, ultrasonic washing, drying and wire collecting, quality testing and warehouse entry, and the like, wherein, the process of electroplating is the electrochemical process by taking nickel and cerium elements as plating additive. The nickelplated mischmetal annealed copper wire prepared by the technique has good metal luster on the surface of the plating layer and excellent adhesiveness, toughness and tractility, is difficult to find a pinhole and suitable for manufacturing aircraft wires and cables as well as special installation conductive core, and can be widely applied to the wires and cables used for installing and connecting electric appliances such as aerocraft, railway, automobile, streamship, etc.

Description

technical field [0001] The content of the invention belongs to the technical field of metal conductive material production, and relates to a production process of electric wire and cable wire, especially a production process of nickel-cerium alloy annealed copper wire. Background technique [0002] With the rapid development of the global economy, the demand for coated wires in the fields of transportation, energy and electricity, and electronics has shown a sharp increase. At present, the known coated wire products on the market are mainly tin-plated, nickel-plated, and silver-plated, among which nickel-plated wires, especially nickel-plated copper wires, have good corrosion resistance, wear resistance, lubricity, hardness, It is more favored by users because of its electrical conductivity and good appearance. Because nickel has good corrosion resistance and high temperature resistance, it is easy to passivate in the air, can withstand strong alkali, and reacts slowly with...
