≤ 0.05%, all impurity add up to≤0.15%, surplus Al.
A kind of production method of 3003H14 aluminum alloy plate materials, using aluminium ingot as raw material, obtains ingot casting, by gained after founding
Ingot casting again through sawing, milling face, ingot casting heating, hot rolling, cold rolling, cleaning straightening and it is horizontal cut, be made thickness be 2.0 ~ 4.0mm and state
For the aluminum alloy plate materials of 3003H14；
In the hot rolling：Using four-roller can backheating roughing and three rack hot finishings, hot roughing start rolling temperature be 480 ~ 510 DEG C, slightly
Total rolling pass control is rolled at 21 or 23, and mill speed is 100 ~ 150m/min, and hot roughing finishing temperature is 410 ~ 500 DEG C；
390 ~ 470 DEG C of hot finishing start rolling temperature, hot finishing 250 ~ 300m/min of coiling speed, hot finishing finishing temperature are 320 ~ 340 DEG C.
The technological parameter of the founding is：730 ~ 750 DEG C of smelting temperature, 725 ~ 735 DEG C of refining temperature, casting temperature 685 ~
695℃。
In the ingot casting heating, ingot casting heating temperature is 510 ± 10 DEG C, and soaking time is 3 ~ 6h.
The cold rolling is to be cold-rolled to finished product thickness by 1 passage, and general working rate is 20 ~ 30%.
The beneficial effects of the present invention are：
Using the present invention production method obtained by 3003H14 aluminum alloy plate materials performance stablize, can save multi-pass cold rolling and
Annealing operation, hence it is evident that shorten production procedure.This method takes full advantage of the characteristics of continuous hot rolling facility, ingot casting is heated, roughing and
The factors such as temperature control and mill speed in finishing stands organically combine, and pass through a time cold rolling, improve surface quality
With plate shape, the product for meeting standard and market quality requirement is produced.
It compares, can reduce more than 4 passages with common process（It is more than 2 passages of cold rolling, the works such as intermediate annealing and finished products
Sequence）, hence it is evident that production procedure is shortened, saves the production time, significantly reduces production cost, improves production efficiency.
It is compared with common process, this method does not have the intermediate annealing process after cold rolling, avoids aluminum strip cold rolling rear surface
The defects of yellowish-brown Annealing oil stain being also easy to produce during remaining ROLLING OIL annealing.
It is compared with common process, this method involves in aluminium after finished product cold rolling cleaning aligning, removes finished surface aluminium powder,
Improve aluminium volume header tailgate shape, the favourable surface for improving finished product plate and strip shape quality, reduction is horizontal to cut procedure technology waste material.
Specific embodiment
Below in conjunction with specific embodiment, the present invention will be further described, but the present invention is not limited only to these embodiments.
Mn：As the main component of the material, play solution strengthening effect, with Fe, Si etc. formed tiny Al-Fe-Mn,
Al-Fe-Mn-Si phases, play an important role of crystal grain thinning.Mn contents are too low, ineffective, Mn too high levels, can be formed coarse, hard
Crisp Al6Mn compounds damage alloy property.
Fe：As the main component of the material, first, invigoration effect is played, second is that it is thin to form high density size with Al, Mn
Small Al-Fe, Al-Fe-Mn improves the alloy welding performance.
Cu、Si：Appropriate Cu and Si contents can play certain solution strengthening effect.But Si contents are excessive, easy shape
Into coarse intermetallic compound, unfavorable subsequent shaping；Cu contents are excessive, can reduce the corrosion resistance of the alloy.
Zn：The element should be strictly limited as impurity element, can reduce stress corrosion cracking tendency.
Aluminium ingot casting is made using semi-continuous casting method, through sawing milling face, heating, hot rolling, cold rolling, cleaning straightening and it is horizontal cut,

Ingot casting heating heat treatment：
Before hot rolling, 510 ± 10 DEG C are carried out to slab ingot, soaking time is the heating of 3 ~ 6 h, and it is inclined can to reduce inside ingot
Interior tissue non-equilibrium phase is dissolved in analysis, improves hot rolling deformation processing performance, obtains good hot-rolled band tissue and performance.Temperature
High easy burning is spent, the long then waste of energy of soaking time is uneconomical.
Hot rolling：
Hot rolling finishing temperature control is adjusted at 320 DEG C -340 DEG C, and according to cold rolling total reduction, finally realizes fine uniform
Crystal grain and object phase.
Cold rolling：
Cold processing ratio 20 ~ 30% can not only ensure enough processing hardening, but also can reduce rolling aluminum volume surface roughness.
Clean straightening：
Aluminium can be removed by cleaning and roll up the foreign matters such as surface aluminium powder and greasy dirt.Aluminium volume can eliminate plate shape by stretch-bending straightening and lack
It falls into, improves glacing flatness, following process is rolled up convenient for aluminium.
