Technical field
The invention belongs to alloy wire manufacturing technology field, be specifically related to a kind of for the high aluminium alloy wire Materials And Manufacturing Processes of the tensile strength on transmission line of electricity.
Background technology
In the past, the electric wire main component that China used as power transmission line is copper. But because copper price is high, cost is high, adds present technological 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 transmission line of electricity now etc. But existing aluminium alloy wires exists, and conductance 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 percentage by weight: 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 kirsite piece is produced in cast;
(2), press composition of raw materials, aluminium block is added in stove and is warming up at 730-740 DEG C and melts, then, be warming up to again at 780-790 DEG C, add after boron antimony lanthanum alloy piece, after fully mixing, then add tantnickel kirsite 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 rapid analysis, after analysis, adjust aluminium fluid component according to the weight ratio of each component in formula, aluminium liquid is carried out to feed supplement;
(3), insulation: step 1 gained aluminium liquid is incubated to 15-20min at 720-730 DEG C;
(4), continuous casting and rolling becomes aluminium alloy rod, wire drawing machine to be drawn into aluminium alloy single line, controls lubricated temperature not higher than 90 DEG C;
(5), timeliness heat treatment, put into 320-330 DEG C of heat-treatment furnace and process 4-5 hour, then be cooled to 180-200 DEG C with 4-6 DEG C/min of speed, temperature retention time is 3-5 hour, then sends into cooling 2-3 hour in 5-10 DEG C of water.
Intensity when silicon can obviously improve tensile strength, hardness, machinability and high temperature, and percentage elongation is reduced. The present invention coordinates by silicon and the trace element such as zirconium, nickel, makes aluminium alloy wires take into account tensile strength and percentage elongation. Make aluminium alloy wires of the present invention there is good performance.
Rare earth elements of the present invention joins the effect that can play microalloying in aluminium alloy; In addition, gas and the much nonmetal stronger affinity that has such as it and hydrogen, can generate the compound that fusing point is high, therefore it has certain dehydrogenation, refining, catharsis; Meanwhile, Rare-Earth Element Chemistry activity is extremely strong, and it can optionally adsorb on the crystal grain boundary of growing up, and hinders the growth of crystal grain, and result causes grain refinement, has rotten effect.
Aluminium alloy conductor of the present invention is compared with existing aluminium alloy conductor, there is high strength and high conductivity simultaneously, more than tensile strength reaches 290Mpa, more than conductance can reach 61.0%IACS, the long-term operation of heat resistance reaches 190 DEG C of above high-strength high-conductivity heat-resistant aluminum alloy wires, can effectively increase wire ability to transmit electricity.
