Abstract
A cable wire material to be used for special communication alloy cable is composed by wt.% of nickel 1-3%, silicon 0.2-0.5%, trace amount of beryllium and the remaining amount of copper, and they are melted and distributed uniformly in the furnace according to the proportioning, then they are drawn as an alloy copper bar by crystallizer and drawing mechanism, furthermore drawn as an alloy copper bar with diameter of 3mm by a wiredrawing machine. One or two annealing are made in the course of drawing and then an alloy supersaturated solid solution is formed through quenching. The ageing process of 1-1.5 hour is carried out under the temperature of 350-450 degree c after the solid solution, and the required wire material can be produced through multiple model drawing after the ageing. The method solves the pollution problem of cadmium vapour produced in the existing cable wire material production.
Description
Affiliated field
The present invention relates to a kind of cable wire of special type voice communication alloy cable wire.
Background technology
Traditional special type voice communication cable wire is copper-cadmium alloy, and it is metallic copper and cadmium to be carried out steps preparations such as founding and drawing, yet easily produces cadmium vapor, contaminated environment in fusion-casting process, influence health of operators.Cost an arm and a leg the manufacturing cost height simultaneously.
Summary of the invention
Easily produce the cadmium vapor pollution problem in the existing cable wire production process for overcoming, the invention provides a kind of copper alloy that contains nickel, silicon and beryllium.
A kind of alloy oxygen-free copper of the present invention cable wire, its weight consists of: nickel 1-3%, silicon 0.2-0.5%, the beryllium of trace and the copper of surplus.
The manufacture method of a kind of alloy oxygen-free copper of the present invention cable wire is: copper, nickel and silicon and beryllium are melted in stove by proportioning, it is evenly distributed, draw the alloyed copper bar by crystallizer and haulage gear then, and make it be drawn into diameter less than 3mm alloyed copper bar with wire drawing machine, pulling process annealing 1-2 time, form the supersaturated solid solution of alloy through quench (solution treatment), and under 350-450 ℃ temperature, carry out 1-1.5 hour Ageing Treatment, pull into required wire rod through multimode again.
Its annealing temperature is 550-650 ℃, and annealing time is 1-2 hour, and the temperature of quenching is 780-850 ℃, and Quenching Soaking Time is 0.5-1 hour, and copper, nickel and silicon fusion temperature in power frequency induction furnace is 1150-1200 ℃.
Nickel of the present invention and silicon substitute cadmium and have eliminated cadmium vapor pollution in the fusion-casting process effectively, have reduced cost simultaneously again.
Embodiment
A kind of alloy oxygen-free copper of the present invention cable wire, with copper, nickel and silicon and beryllium be by weight ratio: nickel 1-3%, silicon 0.2-0.5%, the beryllium of trace and the copper of surplus are added in the power frequency induction furnace, 1150-1200 ℃ of fusing, and notice that stirring is evenly distributed it, draw the alloyed copper bar by crystallizer and haulage gear then, and make it be drawn into diameter less than 3mm alloyed copper bar with wire drawing machine, in pulling process, carry out 1-2 annealing, its annealing temperature is 550-650 ℃, annealing time is 1-2 hour, quench again (solution treatment) obtain the supersaturated solid solution of alloy, the temperature of quenching is 780-850 ℃, under 350-450 ℃ temperature, carry out 1-1.5 hour Ageing Treatment again, after multimode is drawn into required wire rod.
