Description
Technical field
The present invention relates to a kind of production methods of aluminum laminate Heat transmission composite material.
Background technique
Low-carbon economy and sustainable development require automobile industry more energy efficient, more environmentally friendly, safer.And automotive light weight technology technology
It is the effective means for reducing oil consumption, improving fuel economy, reducing exhaust gas discharge.As a kind of important stratiform aluminium alloy compound
Material, it is wide as substrate (core material), macrocomposite that 4343Al and 7072Al alloy is coating using 3003Al alloy
It is general to be applied to car heat exchanger.Due to 3003Al alloy there is also intensity in heat sink applications low, complex process, in vacuum
It can be deformed, the disadvantages of amount of deflection is big, ineffective to the anode loss protection of tube body, therefore pass through in the heating process of soldering
Alloying Design can develop high-strength, high-ductility, highly resistance corrosion aluminothermy transmission composite material, and such high-performance aluminum Heat transmission is multiple
Condensation material (use of substitution copper) is for realizing that the targets such as energy conservation and environmental protection, automotive light weight technology have great importance.
Aluminothermy transmission composite material is not only widely used in automobile and engineering machinery field of heat exchange, such as: radiator of water tank,
Intercooler, oil cooler and air-conditioning system condenser, evaporator, warm-air drier etc.；And in civilian and business air conditioner field, micro- logical
It gets in the fields markets such as road condenser, micro-channel evaporator, power station air cooling field, power station cooling device, air separation plant cooling device
To be applied more.
Aluminothermy transmission composite material is exactly to be combined by two or more aluminum alloy materials by the method for physics
Together, it is then heated to certain temperature, is sent to hot-rolling mill, rolls lower certain drafts back and forth at a slow speed according to specific process,
Make to bond between composite layer and core material, forms a kind of material with new capability.Such as: Chinese patent CN104626674A is disclosed
Production process are as follows: (1) by mill ofves such as the oxide layer Lao Pi of ingot casting surface needed for composite material, by the slab hot-rolling of skin material at
Required thickness, and the removing surface of each layer is clean；(2) by each layer skin material and core material, according to the lamination order and layer of setting
Number, which stacks, to be integrated, and stacking material is synthesized casting (referred to as: soldering) by welding；(3) casting is heated to provide
After temperature, carrying out hot rolling makes composite material reach specific thickness, then carries out being cold-rolled to finished product required thickness；(4) to step (3)
Product annealing, obtain finished product aluminum alloy materials.
But in the production method of the prior art, soldering process is not only very time-consuming and laborious, and low efficiency is at high cost, reaches
Less than the demand of output；And thering is welding poisonous fume and waste residue to generate in welding process, exhaust emission air is serious to damage
Operator's health；Sometimes waste residue tightly depends on the surface of aluminium parts, is difficult to clear up completely, influences the use of aluminum alloy materials
Effect；In addition, because the head of casting of soldering has been welded, bubble when hot rolling between layers is difficult to drive away, is easy to make
It falls off at composite layer, influences final product quality.
Summary of the invention
The object of the present invention is to provide a kind of productions for not needing soldering and continuous production aluminum laminate Heat transmission composite material
Method, to overcome deficiency in the prior art.
The production method of a kind of aluminum laminate Heat transmission composite material of the invention, which is characterized in that be packaged using steel band
Mode bands together each layer alloy material after stacking, is sent into heating furnace and is heated to predetermined temperature, removes steel band after coming out of the stove,
It is then fed into hot-rolling mill and carries out automatic hot calendering bonding, then normally rolled, aluminum laminate Heat transmission composite material can be obtained.
Further, the production method of a kind of aluminum laminate Heat transmission composite material of the invention, which is characterized in that including such as
Lower step:
(1) by surface polish clean layers of material according to setting lamination order and stacking thickness stack neatly；(2) steel is used
It bands together each layer alloy material after stacking to obtain casting A with packing manner；(3) casting A is sent into heating stove heating,
It is heated to predetermined temperature, dismounting steel band on hot rolling roller-way is sent into after coming out of the stove and obtains casting B；(4) casting B is sent into hot-rolling mill, led to
The layers of material of casting B is adhesively-bonded together to form ingot casting C by the automatic hot calendering bonding for crossing hot-rolling mill；(5) casting C is carried out again
Normal rolling, obtains final products.
Further, in the step (1), the layers of material includes core material aluminium alloy and composite layer aluminium alloy；
The composite layer aluminium alloy can have 1~5 layer according to the difference of ingredient；The core material aluminium alloy and the composite layer aluminium
Alloy is stacked according to the sequence that client needs.
Further, in the step (2), the steel band packing manner are as follows: using 4~8 elongated steel bands,
It symmetrically ties up the two sides of casting A.
Further, in the step (4), the automatic hot rolling adhesion process are as follows: the middle position of casting B,
It is parked at the Roll-gap position of hot-rolling mill, after hot-rolling mill closes roll gap, presses automatic bonding start button, it is automatic first to be rolled to side,
Stop to the tail portion of casting B, reversely stops again to the head that casting B is rolled in the other side, then reversely roll to middle position and stop automatically
Only, the first passage terminates；The second passage and subsequent passage are carried out according still further to regulation sequence, until the layers of material of casting B
It is adhesively-bonded together to form new ingot casting C；The automatic calender bonding temperature is 430~520 DEG C.
Further, in the step (5), the described normal rolling includes: that ingot casting C is carried out multi-pass by hot-rolling mill
Hot rolling reaches specific thickness and forms aluminium volume；After aluminium volume is cooling, into cold rolling mill process, including annealing process.
Using the production method of aluminum laminate Heat transmission composite material of the invention, due to having used steel band to tie up and automatic heating
The production method that bonding combines is rolled, a large amount of manpower and material resources can be not only saved, production efficiency is improved, with prior art phase
Than the product of every same batch of production can save for 60% or more time；Continuous production can guarantee that the quality of product is stablized
Property；Moreover, because do not need to weld, therefore toxic exhaust emission will not be generated influence air quality in air, not have weldering
The waste residue connect, which remains in, influences product quality in material；In addition, due to using automatic hot calendering bonding, layer and interlayer do not have soldering envelope
It closes, the air in gap is easy to be discharged, and can also improve product quality.
