The present invention is characterized in that the contents of aluminum ingot impurities and alloying additional elements are controlled strictly, parameters of temperature, cooling, and speed, etc. are controlled through different manufacturing stages, the strength and the survival rates of rods and wires are controlled, electric conductivity and heat-resisting performance are enhanced and stabilized, and the bottleneck restriction of continuous production caused by adopting conventional technical heat treatment technologies is overcome. The present invention has the advantages of power and time saving for heat treatment, reduced cost, enhanced and stabilized quality and yield, and obvious economic benefit.
Description
Technical field: the present invention relates to a kind of manufacturing of electrical material, is a kind of manufacturing technology of cond aluminium, or rather, is a kind of manufacturing technology of non-thermal treatment type 60%IACS high-conductive heat-resistance aluminium alloy wire.
Background technology: at present, obtain high-conductive heat-resistance aluminium alloy wire, be to use aluminium ingot through conventional melting, and alloying and continuous casting and rolling obtain the alloy pole stock, and this pole stock just can reach mechanical, electrical performance demands again through backguy and thermal treatment.But during thermal treatment, furnace volume is limited, and is both time-consuming, takes electricity again, once can only handle the small amount of aluminum alloy wire, makes intermediates overstock in a large number on heat treatment step, causes the quantity-produced 'bottleneck' restrictions, also can be because of a large amount of power consumptions, the cost that increases product consuming time.
Summary of the invention: the present invention provides a kind of in manufacturing processed, by detecting and batching the content of control aluminium ingot impurity element and alloy element, and by the different manufacturing stages, parameters such as controlled temperature, cooling and speed, control lever, line strength reach performance requriements.Thereby saved the process of thermal treatment process, eliminated the quantity-produced 'bottleneck' restrictions, improved product performance, improved stability and yield rate, adapted to and produce by batch continuously, can bring distinct economic.
The present invention is done in such a manner: select foreign matter content silicon≤0.13%, and iron≤0.20%, copper≤0.01%, gallium≤0.03%, magnesium≤0.03%, the aluminium ingot of other every kind impurity≤0.03 is put into the shaft furnace fusing; The adding scope is at 0.01～1.0% zirconium, as the interpolation element of Alloying Treatment; Through the processing that stirs, refining degasification, slagging-off with solid insulating covering agent aluminium coating liquid surface, and were left standstill 45～60 minutes; With the chemical on-the-spot sample analysis of high speed, monitoring, adjustment, control element content; Through chute, filtration unit, go into continuous caster and carry out continuous casting and become aluminum alloy bar, go into the tandem rolling unit, roll into aluminium alloy rod, on continuous drawing machine, pull into the aluminium alloy product line of required diameter.
Wherein the Alloying Treatment temperature of aluminum liquid is advisable with 730～750 ℃; Continuous caster is made up of wheeled crystallizing wheel etc., and the temperature of continuous casting aluminium liquid is 690～740 ℃, crystallizing wheel water coolant total pressure 0.2～0.4Mpa, and the tandem rolling unit is made up of 8～15 frames three roll-type or double-roller type.Filtration unit adopts glass cross, perhaps adopts foam ceramic tile or pipe, and it is 470～530 ℃ that aluminum alloy bar advances to roll temperature, emulsion of rolling mill total pressure 0.1～0.2Mpa, and the finishing temperature of aluminium alloy rod is at 160～330 ℃.Pull wire speed 8～17 meter per seconds.
Description of drawings: Fig. 1 is a manufacturing process synoptic diagram of the present invention.
Embodiment: shown in figure, adopt the standard aluminium ingot of 99.7% purity, (main chemical: silicon≤0.13%, iron≤0.20%, copper≤0.01%, gallium≤0.03%, magnesium≤0.03%, other impurity every kind≤0.03%) dissolve at shaft furnace, aluminium liquid carries out Alloying Treatment in holding furnace, contain zirconium 0.01～1.0% in the aluminium liquid, carry out homogenizing and stir, with solid or gas or solid and gas mixing, or gas gas blended refining agent refining, solid insulating covering agent aluminium coating liquid surface, alloy aluminum liquid refining temperature is advisable with 730～750 ℃, aluminium liquid time of repose 45～60 minutes.With the chemical on-the-spot sample analysis method of high speed, analyze zirconium, silicon, iron level, by monitoring, when departing from, content adjusts, reach the composition of control alloy aluminum liquid.By the effusive aluminium liquid of holding furnace, through chute, in last casting ladle, use the glass cross bag filtration, or filter with foam ceramic tile or pipe, casting ladle enters the liquid filling machine crystallizing wheel under the aluminium liquid warp then, carries out continuous casting, the aluminium alloy pouring temperature: 720 ℃; Crystallizing wheel water coolant total pressure: 0.3Mpa.Cast bar enters three-roller type 15 frame tandem rolling units and is rolled.Advance to roll 500 ℃ of temperature, cooling and lubricating emulsion total pressure 0.1Mpa, the φ 9.5mm aluminium alloy rod that shuts out carries out cooling of convection current emulsion or naturally cooling in the pipe of climbing, use loose ring distaff mode lopping distaff then.280～300 ℃ of heat-resisting aluminium alloy bar finishing temperatures; the backguy on 13 mould sliding type big drawing machines or non-sliding type 8 moulds, 10 mould big drawing machines of Φ 9.5mm loose ring heat-resisting aluminium alloy bar; pull wire speed 8～17 meter per seconds are advisable, heat-resisting aluminium alloy product line, line through scope at 5.0～2.3mm.
