Technical field
The invention belongs to alloy wire manufacturing technology field, be specifically related to a kind of for the high aluminum alloy line Materials And Manufacturing Processes of the tensile strength on transmitting line.
Background technology
In the past, the electric wire main component that China used as transmission line is copper.But because copper price is high, cost is high, adds present technical progress, and the application percentage of aluminium alloy conductor is in continuous increase.Ordinary steel core aluminum conductor, aluminium Baogang core wire, alumite wire and high strong aluminum conductor of using on transmitting line now etc.But existing aluminium alloy wires exists, and electric conductivity is not high, intensity is not high, thermo-labile, large, the line of electric conductivity difference consumes high series of problems in varying environment.
Summary of the invention
The object of this invention is to provide aluminium alloy wires that a kind of tensile strength is high and preparation method thereof, the aluminium alloy wires of production can meet tensile strength requirement really.
Technical solution of the present invention is as follows:
The aluminium alloy wires that tensile strength is high, is characterized in that wherein containing the composition of following weight percent: silicon 0.6-0.7, zirconium 0.05-0.07, nickel 0.2-0.3, copper 0.05-0.09, zinc 0.6-0.75, boron 0.025-0.035, antimony 0.01-0.02, lanthanum 0.016-0.026, surplus are aluminium.
The preparation method of the aluminium alloy wires that tensile strength is high, is characterized in that comprising the following steps:
(1), in the ratio of boron, antimony, lanthanum mass ratio 2:1:1 will boron, antimony, lanthanum powder drops in stove and melts, after refining, boron antimony lanthanum alloy piece is produced in cast; In silicon, nickel, zinc, the ratio of 6:2:6 will silicon in mass ratio, nickel, zinc powder drops in stove and melt, and after refining, tantnickel zinc alloy piece is produced in cast;
(2), press composition of raw materials, aluminium block is added in stove and is warming up at 730-740 ℃ and melts, then, be warming up to again at 780-790 ℃, add after boron antimony lanthanum alloy piece, after fully mixing, then add tantnickel zinc alloy piece and other alloying ingredient composition, after fully mixing, pass into refining agent and carry out refining, skim; Again aluminium liquid is carried out to stokehold chemistry real-time analysis, after analysis, according to the weight ratio of each component in formula, adjust aluminium fluid component, aluminium liquid is carried out to feed supplement;
(3), insulation: step 1 gained aluminium liquid is incubated to 15-20min at 720-730 ℃;
(4), continuous casting and rolling becomes aluminium alloy rod, drawing wire machine to be drawn into aluminium alloy single line, controls lubricated temperature not higher than 90 ℃;
(5), timeliness thermal treatment, put into 320-330 ℃ of heat treatment furnace and process 4-5 hour, then be cooled to 180-200 ℃ with 4-6 ℃/min of speed, soaking time is 3-5 hour, then sends into cooling 2-3 hour in 5-10 ℃ of water.
Intensity when silicon can obviously improve tensile strength, hardness, machinability and high temperature, and unit elongation is reduced.The present invention coordinates by silicon and the trace elements such as zirconium, nickel, makes aluminium alloy wires take into account tensile strength and unit elongation.Make aluminium alloy wires of the present invention there is good performance.
