Description
Technical field
The present invention relates to metal working technical area, in particular to the heat of a kind of copper aluminum interface alloy composite bus
Process technique.
Background technology
The conductive material that electric power electric industry is commonly used at present is copper and aluminum, and he is also the heat exchange material commonly used in the world simultaneously
Material, the moment heat absorption capacity of copper ratio fast 1.61.6 times of aluminum, but the speed of heat radiation is slow, and the radiating rate of aluminum is than copper billet 2.33
Times.But with oxidizable in higher than room temperature environment, particularly in the environment containing corrosive gas.So the condition that industrial and mineral is severe
Under, reuse aluminum displacement for copper bar.As two kinds of metal materials are combined, will be perfect conduction, heat exchange material.The most no matter
For conduction or heat conduction, using copper aluminum composite material is all splendid selection.With aluminum for matrix outer layer complex copper, it is applied to supply
Level rate is more than the line conductor row of power frequency, line.With copper for matrix outer layer clad aluminum, it is adaptable to there is conduction, the heat conduction overlooked under industrial and mineral.
But Copper-Aluminum compound comes in its heat treatment process, Cu-Al alloying is prone to produce brittle alloy, controls heat treatment, i.e. controls to close
Aurification degree, thus ensure that joint product can bending, the serviceability such as not stratified.
Summary of the invention
It is an object of the invention to provide the Technology for Heating Processing of a kind of copper aluminum interface alloy composite bus to reach to improve institute
The Copper-Aluminum compound bus of preparation have can bending, the purpose of the serviceability such as not stratified, solve the compound mother of existing albronze
Line in its heat treatment process, Cu-Al alloying be prone to produce brittle alloy problem.
For realizing the object of the invention, the technical scheme of employing is: the heat treatment work of a kind of copper aluminum interface alloy composite bus
Skill, it is characterised in that: its heat treatment comprises the following steps that:
(1) annealing furnace is used to carry out respectively than original metal tubing copper pipe, the original metal band aluminium strip for 1:2 thickness
Annealing, wherein the annealing temperature of copper strips is 300～350 DEG C, and temperature retention time is 4-4.5 hour；The annealing temperature of aluminium strip is
200～250 DEG C, temperature retention time is 2-3 hour；Annealing process is inert gas shielding；
(2) by automatic jacketing machine, the aluminium strip after annealed process being filled the inside to copper pipe, copper pipe, aluminium strip are the most successively
Completing composite rolling for the first time through uncoiler, straightener, sanding apparatus, photoelectricity centering, composite rolling mill, reduction ratio controls 70
～75%, the composite rolling band obtained employing annealing furnace is carried out intermediate annealing process；
(3) the composite rolling band processed through intermediate annealing being carried out 4 passage finish rolling, every time reduction ratio controls 15
～30%, the most finally make annealing treatment and obtain Copper-Aluminum compound band bus.
Employing present invention have the advantage that
1, Technology for Heating Processing described herein is used, the diffusion annealing temperature of different materials, temperature retention time and elimination
The defects such as surface blisters, have been effectively ensured material and can bear the profit that the temperature difference of increasing is expanded with heat and contract with cold, and be prone to shear, beat
Hole, Bending Processing, do not ftracture, do not separate, and interface bond strength constantly strengthens during follow-up use.
Detailed description of the invention
Below by specific embodiment, the present invention is described in further detail.
A kind of Technology for Heating Processing of copper aluminum interface alloy composite bus, it is characterised in that: its heat treatment includes following technique
Step:
(1) annealing furnace is used to carry out respectively than original metal tubing copper pipe, the original metal band aluminium strip for 1:2 thickness
Annealing, wherein the annealing temperature of copper strips is 300～350 DEG C, and temperature retention time is 4-4.5 hour；The annealing temperature of aluminium strip is
200～250 DEG C, temperature retention time is 2-3 hour；Annealing process is inert gas shielding；
(2) by automatic jacketing machine, the aluminium strip after annealed process being filled the inside to copper pipe, copper pipe, aluminium strip are the most successively
Completing composite rolling for the first time through uncoiler, straightener, sanding apparatus, photoelectricity centering, composite rolling mill, reduction ratio controls 70
～75%, the composite rolling band obtained employing annealing furnace is carried out intermediate annealing process；
(3) the composite rolling band processed through intermediate annealing being carried out 4 passage finish rolling, every time reduction ratio controls 15
～30%, the most finally make annealing treatment and obtain Copper-Aluminum compound band bus.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, that is made any repaiies
Change, equivalent, improvement etc., should be included within the scope of the present invention.
