Embodiment

[0027] A process for producing a soft copper-clad steel wire by a welding cladding method is characterized in that the following steps are included in sequence:

[0028] (1) Drawing, pull the steel wire with a wire diameter of 9.0-10.0mm to a wire diameter of 8.0-8.6mm;

[0029](2) Low-temperature tempering, put the drawn steel wire into a vacuum tempering furnace for low-temperature heat treatment, the tempering temperature is 420-500°C, the heating time is 1-2 hours, and the holding time is 5.5-6.5 hours; Cool the furnace for 3 hours, and then turn on the air cooler to cool it to about 260°C; eliminate the work hardening of the steel wire, improve the plasticity, and facilitate subsequent processing; at the same time, the lubricating liquid remaining on the surface of the steel wire in the previous process is carbonized at high temperature to form a loose oxide scale , easy to remove scale by subsequent pickling;

[0030] (3) pickling to remove the scale on the surface of t...

Abstract

The invention relates to a production process of a copper clad steel conductor and particularly provides a process for producing a soft-state copper clad steel conductor by adopting a welding cladding method. The process comprises the following steps: drawing, tempering at a low temperature, washing with acid, washing with water, neutralizing, drying, straightening and removing rust, cladding and welding, singly drawing, continuously drawing, tempering at a high temperature, drawing by a water tank, passivating, and carrying out online detection on the copper clad steel conductor by using a surface online flaw detection device, and carrying out take-up and winding. The process for producing the soft-state copper clad steel conductor by adopting the welding cladding method has the advantages of low production cost, safe and environment-friendly production process, and stable quality and high yield of the produced copper clad steel conductor.

Description

technical field [0001] The invention relates to a production process of copper-clad steel wire. Background technique [0002] Copper-clad steel wire is a composite wire with a steel wire as the core and a layer of copper on its surface. It is mainly used in the communication and electronic industries, and is a replacement product for special materials for communication cables. The product has the tensile strength and toughness of steel, the electrical conductivity and high-frequency characteristics of copper, and has the advantages of saving copper and reducing costs. It has the advantages of both copper and steel. In a certain high frequency range, its impedance value is equal to that of pure copper wire, but its tensile strength can be several times that of pure copper. In communication and telecommunications, copper-clad steel wire has the same conductivity as copper wire, but because copper-clad steel wire has good mechanical strength, light weight and no creep, it can ...
