Technical field
The invention belongs to the rolling technical field of metal, is specifically a kind of aluminum alloy tank body material cold continuous rolling production method.
Background technology
As tank material final finished needs H19 states, cold rolling reduction reach more than 85%, cold rolling general arrangement
Four-pass is produced.Existing method is produced using single chassis, needs four-pass rolling is repeated, and causes existing milling method tool
There is following deficiency：
1）Low production efficiency：The cold rolling employing single chassis production of existing tank material, need to be repeated four-pass rolling, cause production
Efficiency is low；
2）Material anisotropic is big；
3）The moulding strain ratio r values of material are little；
4）Stretching easy fracture.
The content of the invention
In view of this, it is an object of the invention to provide a kind of aluminum alloy tank body material cold continuous rolling production method, can not only
Improve production efficiency, and the aluminum alloy tank body material for obtaining has, and material anisotropic is little, the moulding strain ratio r values of material big and draws
Stretch the advantage of not easy fracture.
To reach above-mentioned purpose, the present invention provides following technical scheme：
A kind of aluminum alloy tank body material cold continuous rolling production method, adopts " 2+2 " two passage Stand Mill tandem rolling, and pressure to be assigned as：The
A time：2.3- Stand Mill tandem rolling -1.05；Second passage：1.05- Stand Mills tandem rolling-finished product.
Further, ROLLING OIL refrigerating work procedure is set between Stand Mill, it is in the ROLLING OIL refrigerating work procedure, ROLLING OIL is straight
Spray is connect in strip surface, and controls finishing temperature 145-170 DEG C.
Further, the spray flux of the ROLLING OIL is 0-800L/min.
The beneficial effects of the present invention is：
The aluminum alloy tank body material cold continuous rolling production method of the present invention, produces tank material using " 2+2 " tandem rolling mode, by the method
On the one hand material structure performance can be improved, more conducively client well uses；On the other hand production efficiency can be greatly improved, is dropped
Low production cost, i.e., compared to the existing single chassis mode of production, can not only improve production efficiency, and the aluminium alloy for obtaining
Tank material has the advantages that material anisotropic is little, the moulding strain ratio r values of material are big and stretch not easy fracture.
Description of the drawings
In order that the purpose of the present invention, technical scheme and beneficial effect are clearer, the present invention provides drawings described below and carries out
Explanation：
Fig. 1 is using tank material fracture microscopic structure schematic diagram obtained in single stand cold mill；
Fig. 2 is the cold rolling obtained tank material fracture microscopic structure schematic diagram of Stand Mill tandem rolling.
Specific embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings, so that those skilled in the art can be with
It is better understood from the present invention and can be practiced, but illustrated embodiment is not as a limitation of the invention.
The aluminum alloy tank body material cold continuous rolling production method of the present embodiment, adopts " 2+2 " two passage Stand Mill tandem rolling, and depresses
It is assigned as：First passage：2.3- Stand Mills tandem rolling -1.05；Second passage：1.05- Stand Mills tandem rolling-finished product.
Further, ROLLING OIL refrigerating work procedure is set between Stand Mill, it is in the ROLLING OIL refrigerating work procedure, ROLLING OIL is straight
Spray is connect in strip surface, and finishing temperature 145-170 DEG C is controlled, and the spray flux of ROLLING OIL is 0-800L/min, this enforcement
The spray flux of the ROLLING OIL of example is 400L/min, controls 150 DEG C of finishing temperature；Certainly, according to practical situation, the spray of ROLLING OIL
Amount can also be 0L/min, 200 L/min, 600 L/min and 800 L/min, and finishing temperature can also for 145 DEG C, 160
DEG C, 165 DEG C and 170 DEG C, be not repeated.
The aluminum alloy tank body material cold continuous rolling production method of the present embodiment is produced compared to existing single chassis, with following excellent
Point：
1）Production efficiency is higher：The cold rolling employing single chassis production of existing tank material, is repeated four-pass rolling, its pressure point
With for：2.3-1.5-1.05-0.55- finished product；The present embodiment adopts " 2+2 " two passage Stand Mill tandem rolling, its pressure to be assigned as：
（2.3- Stand Mills tandem rolling -1.05）-（1.05- Stand Mills tandem rolling-finished product）, the present embodiment has the production cycle shorter, production effect
The higher advantage of rate；
2）Material anisotropic is less：The present embodiment produces tank material using " 2+2 " tandem rolling mode, with respect to the life of existing single chassis
Product method, the mechanical performance contrast in aluminium sheet all directions are as shown in table 1, tensile strength sigmabAll directions maximum difference Stand Mill
For 1.61%, and the existing single chassis mode of production is 3.13%；Elongation percentage ε maximum differences Stand Mill is 3.64%, and existing list
The frame mode of production is 23.4%；Data above can be seen that the anisotropic of the tank material mechanical performance of Stand Mill rolling production
It is relatively smaller, material it is relatively more stable in performance.
1 Stand Mill tandem rolling of table and single chassis rolling tank material finished product machinery performance comparison
3）The moulding strain ratio r values of material：The Lankford r value of material represents plate deformability in a thickness direction, r values
Bigger, the thinning ability of opposing unstability is bigger, is less susceptible to thickness to deformation, that is, is less prone to thinning or thickens, material
Deep drawability is better.Table 2 is listed the present embodiment and is contrasted with the r values of conventional individual frame mill product tank material, it can be seen that double
Frame rolling production tank material finished product r values are bigger, and deep drawability more preferably, is more beneficial for client's use.
