Abstract
The present invention discloses a kind of aluminum alloy foil for heat exchanger of air conditioner, cooler, heater unit, radiator, etc. in automobile and its production process. The aluminum alloy foil is produced with Al, Fe, Si, Mn, Zn, Cu, Mg, Zr and Ti, and through smelting, casting, homogenizing, cutting, milling, heating, rolling, annealing, finish rolling and other steps. The aluminum alloy foil thus produced has no deformation, subsidence and collapse.
Description
(1) technical field
The present invention relates to a kind of aluminium foil and production method thereof.Specifically, be interchanger such as motorcar air conditioner, charge air cooler, warm-air drier and water tank alloy foil and production methods thereof.
(2) background technology
At present, employed alloy foil on the interchanger such as motorcar air conditioner, charge air cooler, warm-air drier and water tank mainly is 3003 or the 3A21 aluminium foil.The former is made by raw materials such as silicon, iron, copper and manganese, and the latter is made by raw materials such as silicon, iron, copper, manganese and titaniums.Because these two kinds of aluminium foils do not have the anodic protection effect, can increase the spot corrosion of aluminium foil when soldering.Therefore, the aluminium foil of these two kinds of trades mark when soldering, all be easy to generate the distortion and subside.
Because the fusing point of these two kinds of trade mark aluminium foils is all very low, and fusing point one is low, its recrystallization temperature is just low again.So, the distortion in the time of also can making soldering strengthens.
On the other hand, manganic compound is the key that improves solidus temperature, and 3003 and two kinds of trade mark aluminium foils of 3A21 in the content of manganese all lower.The content one of manganese is low, and solidus temperature is just low.Therefore, the solidus temperature of these two kinds of trade mark aluminium foils is all lower.The situation of also easily subsiding during soldering.
Though can overcome the distortion of above-mentioned two kinds of aluminium foils and subside the raising that increase thickness can bring user's production cost again by increasing thickness.All more than 0.15mm, under the pursuit of most current cost target, moreover the thickness of aluminium foil just develops towards more and more thinner direction the aluminum foil thickness of above-mentioned two kinds of trades mark.Therefore, above-mentioned two kinds of trade mark aluminium foils are inapplicable.
In addition, in traditional aluminium foil production method, be after being rolled down to finished product thickness, just carry out anneal, can make fibrous crystal grain return near round shape crystal grain.So, when soldering, the silicon of soldering place easily is diffused into the inside of aluminium foil base material, and then aluminium foil is formed melt erosion and be out of shape.Therefore, the reviewing phenomenon often appears.
(3) summary of the invention
The purpose of this invention is to provide a kind of alloy foil.This alloy foil can not be out of shape and subside during soldering.
Another object of the present invention provides a kind of production method of alloy foil.The alloy foil of Sheng Chaning the reviewing phenomenon can not occur during soldering in this way.
Above-mentioned purpose of the present invention is realized by following technical solution:
Alloy foil of the present invention, make by the raw material of following parts by weight:
0.4～0.8 part of iron; 0.6～1.0 part of silicon; 1.4～1.7 parts in manganese; 1.3～1.6 parts on zinc; 0.01～0.05 part of copper; 0.01～0.05 part in magnesium; 0.05～0.15 part of zirconium; 0.03～0.15 part of titanium.
Produce the method for above-mentioned alloy foil, may further comprise the steps successively:

(2) casting
Under 680～700 ℃ temperature, above-mentioned molten metal is cast as ingot blank with 65～90mm/ minute speed;
(3) homogenizing is handled
It is 580～600 ℃ electric furnace that above-mentioned ingot blank is put into temperature, and constant temperature kept 25～28 hours, carries out homogenizing and handles;
(4) sawing with mill face
The ingot blank of handling through homogenizing is carried out sawing, and saw removes its head, tail; Then, two big face is carried out milling, eliminate defective with milling machine;
(5) heat treated
To put into process furnace through sawing and the ingot blank that mills face, under 480～520 ℃ temperature, keep 10～12 hours;
(6) hot rolling
Is that 480～520 ℃ ingot blank carries out hot rolling with milling train to temperature, is rolled into the thin plate that thickness is 6.5～7mm;
(7) middle temperature rolling
Being lower than under 220 ℃ the temperature, above-mentioned sheet rolling is become the thick thin plate of 3～3.5mm;
(8) cold roughing.
At normal temperatures, above-mentioned 3～3.5mm is thick sheet rolling becomes the thick thin plate of 1.8～2.0mm;
(9) roll in cold
At normal temperatures, sheet rolling that above-mentioned 1.8～2.0mm is thick becomes the aluminium foil of 0.18～0.2mm;
(10) anneal
It is 410～430 ℃ electric furnace that the aluminium foil of above-mentioned 0.18～0.2mm is put into temperature, and constant temperature kept 10～14 hours, carried out anneal;
(11) cold finish rolling
To become 0.1～0.12mm thick through the aluminum foil rolling that anneal is crossed with finishing mill, be alloy foil of the present invention.
Adopt such scheme, have the following advantages:
Because contain zinc in the alloy foil prescription of the present invention, zincification has 2 effects: the one, the corrosion potential of alloy foil is reduced, zincification is many more, and current potential descends many more, and the foil of zincification is preferentially corroded as anode, thus the protective medium passage; The 2nd, can reduce the passive film intensity of alloy foil, it is peeled off easily and become general corrosion, thus the purpose that reaches distortion when suppressing spot corrosion and then prevention soldering and subside.
Owing to contain pick in the present invention's prescription,, add the recrystallization temperature that pick can be improved alloy foil again because of the fusing point of pick is high especially.So, also can play the effect that increases welding strength indirectly.Thereby the distortion when having avoided soldering.
Because suitably heightened the content of silicon in the prescription of the present invention, flowability improves when making soldering, has increased clearance filling capability and has made the welding zone homogeneous microstructure fine and closely woven, thereby improved brazing quality.
Owing to improved the content of manganese in the prescription of the present invention, its objective is in order to increase the calorize manganic compound.This compound can obviously improve the solidus temperature of alloy foil, thereby has increased the hot strength of alloy foil, the reviewing when having prevented soldering.
In addition, in production method, carry out cold finish rolling after the employing annealing, adopt the ideal working modulus, the suitable elongation of control crystal grain can stop scolder to its internal divergence when soldering, to guarantee enough solidus temperatures.Also played anti-purpose of subsiding.
