At present, obtain high-conductive heat-resistance aluminium alloy wire, be to obtain the alloy pole stock through conventional melting, alloying, concise and common continuous casting and rolling with aluminium ingot, this pole stock is again through backguy and thermal treatment, just can reach the above mechanical, electrical performance demands of 60%IACS, the holding furnace that uses is flat at present, all alloy liquid can not be toppled over totally after each melting, in body of heater, leave residual alloy liquid, to exert an influence to the configuration of the alloy liquid of next stove, and make the salient featuress such as electric conductivity, intensity survival rate of high-conductive heat-resistance aluminium alloy wire also not reach the stably manufactured purpose.
Summary of the invention
The purpose of this invention is to provide a kind of method that reaches the manufacturing high-conductive heat-resistance aluminium alloy wire of performance requriements.
For realizing above purpose, technical scheme of the present invention provides a kind of method of making high-conductive heat-resistance aluminium alloy wire, it is characterized in that, the method for manufacturing is:
The first step selected aluminum matrix and alloy pig: selecting foreign matter content is the aluminium ingot of silicon below 0.08%, iron≤0.16%, copper≤0.01%, (titanium Ti+ vanadium V+ chromium Cr+ manganese Mn)≤0.015%, other every kind impurity≤0.03%;
The second step aluminum substrate fusing: aluminum substrate is put into the shaft furnace fusing, and to be placed on the body of heater that can the fascinate angle of can fascinating be the 25-28 degree, and the aluminium liquid flip angle in the stove is in the holding furnace of 20-23 degree;
The 3rd step alloy preparation: prepare uniform alloy liquid: add the zirconium of alloying element 0.03～0.5% and 0.01～0.1% yttrium;
The 4th step process is handled: through uniform stir process, degasification, slagging-off with solid insulating covering agent aluminium coating liquid surface, and are left standstill more than 30 minutes in kettle furnace;
The 5th step on-the-spot sample analysis adjustment: with the high-speed light spectrometer principal element is carried out the stokehold rapid detection, is monitored, adjusts, control element content;
The 6th step casting and crystallization: the alloy aluminum liquid in the kettle furnace through chute, is filtered by filtration unit, be aided with the boron alloy that adds crystal grain thinning 0.001～0.01% and enter special-purpose aluminium alloy continuous caster and carry out continuous casting, the formation aluminium alloy cast ingot;
The 7th step, rolling: aluminium alloy cast ingot is gone into special-purpose aluminium alloy tandem rolling unit roll into aluminium alloy rod;
The 8th the step: drawing is stranded: on continuous drawing machine, pull into the aluminium alloy product line of required diameter, and on frame type stranding machine stranded stranding.
Described Alloying Treatment, the holding furnace of employing automatization, fire box temperature is controlled at 850-980 ℃, and temperature of aluminum liquid is controlled at 720-740 ℃; Described aluminium alloy continuous caster is made up of the wheeled crystallizing wheel of H type; Described aluminium alloy tandem rolling unit is the built-up type that two rollers add three rollers; It is 480～520 ℃ that the aluminum alloy bar that described tandem rolling unit is rolled advances to roll temperature, continuous mill cooling and lubricating emulsion total pressure 0.1～0.2Mpa, and the finishing temperature of aluminium alloy rod is at 250～300 ℃; The pull wire speed of described continuous drawing machine is at 8～25 meter per seconds.
The present invention's strict control aluminium ingot impurity and alloying are added constituent content, and by the different manufacturing stages, the homogeneity of control alloy, adopt the kettle furnace of automatization temperature control, the body of heater of the kettle furnace of this type of automatization temperature control angle of can fascinating is the 25-28 degree, aluminium liquid flip angle in the stove is the 20-23 degree, because body of heater can fascinate the angle greater than aluminium liquid flip angle, can guarantee that aluminium liquid topples over totally fully in the body of heater of holding furnace, thereby guarantee and control the homogeneity of the alloy liquid configuration of second stove, control the temperature of each point, processing parameters such as temperature of cooling water and flow and production rate, use in the stove simultaneously and external refining, make degasification obvious with the slagging-off effect.Crystal grain refinement is once more used in crystallization, guarantees that crystalline state is good, and the aluminium alloy continuous casting and rolling milling train that adopts two new-type rollers to add three roller group types is controlled well and rolled bar technology, makes aluminium alloy rod obtain fully distortion, excellent property.
Advantage of the present invention is to make high-conductive heat-resistance aluminium alloy wire can reach performance requriements.
