Description
Technical field
The present invention relates to a kind of metal rolled production methods, and in particular to a kind of aluminium cold rolling production tank material production method,
Belong to metal material moulding and processing technique field.
Background technique
During aluminum cold-rolling mill production rolling tank material, because tank material H19 state determines in the technique production operation of rolling
Temperature requirement is high, determines that the mill speed of section must be in 950m/min or more.
Existing cold-rolling mill high-speed rolling process has following defect:
1. machine arranges, interior working roll roughness decline is very fast, and working roll and strip surface do not have enough frictional force not to be able to satisfy continuously
Rolling requirements, lead to the more whole production efficiency for influencing cold-rolling mill of the working roll replacement frequency, and each roll change adds warm roller and prepares
Time about 1.5 hours；
2. every a pair of working roll gradually building up with viscous aluminium layer in the operation of rolling, causes the RPC value on working roll roll surface to increase,
Aluminum strip surface is had an impact during the rolling process, is increased brokenly when especially having punching press in the following process of band, drawing high
The probability of wall.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of aluminium cold rollings to produce tank material production method.
The present invention to achieve the above object, is achieved through the following technical solutions:
A kind of aluminium cold rolling production tank material production method, comprising the following steps:
1) surface layer is carried out to the roll of grinding completion of processing and applies plating；
2) the aluminium alloy strips temperature rolled will be needed to control at 50-60 DEG C；
3) aluminium alloy strips are sent to cold-rolling mill to go out to carry out multiple batch cycle rolling, for the first time the calendering rate 25-30% of rolling,
The calendering rate 35-40% of second of rolling, the calendering rate 40-50% of last rolling；Wherein coating processing method is as follows: being made using lead
For anode, roll is electroplated one layer of hard chrome in the tank liquor containing chromic anhydride, sulfuric acid and catalyst, cathode efficiency 30%-40%,
Chrome layer thickness control is in 8-10um, and chrome layer hardness is in HV900-1200.
The aluminium cold rolling produces tank material production method preferred embodiment, uses edge thermal jet system in band in the operation of rolling
Wide edge range carries out ROLLING OIL thermal jet to strip side portion and working roll region, and thermal jet quantity spray head is 4-5, thermal jet
Temperature whole-process control is at 105 DEG C -115 DEG C；The target velocity of mill product outlet is 1050m/min-1200m/min.
The aluminium cold rolling produces tank material production method preferred embodiment, and chromic anhydride and sulfuric acid mass ratio are 100:1, and catalyst is dense
Degree 10%.
The present invention has the advantages that
Tandem rolling mode produces tank material, the roll change frequency in production process is on the one hand reduced by this method, and then effectively improve
The production efficiency of cold-rolling mill tank material.The aluminum strip tank material surface quality produced by this method is more excellent, especially for rear
Before every metallicity in continuous tank material process can be better than, broken wall problem has also obtained effective solution.
Detailed description of the invention
Attached drawing is used to provide further understanding of the present invention, and constitutes part of specification, with reality of the invention
It applies example to be used to explain the present invention together, not be construed as limiting the invention.
Fig. 1 is that roll of the present invention applies the metallographic microscope before plating.
Fig. 2 is roll coating of the present invention treated metallographic microscope.
Specific embodiment
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, it should be understood that preferred reality described herein
Apply example only for the purpose of illustrating and explaining the present invention and is not intended to limit the present invention.
A kind of aluminium cold rolling production tank material production method, which comprises the following steps:
1) surface layer is carried out to the roll of grinding completion of processing and applies plating；
2) the aluminum alloy hot rolling strip temperature control for needing to roll is avoided in cold rolling mill to 50-60 DEG C because of oil film
It is thin viscous wound, the appearance of the defect of reverse-printed roll banding occur；
3) aluminium alloy strips are sent to cold-rolling mill to go out to carry out multiple batch cycle rolling, for the first time the calendering rate 25-30% of rolling,
The calendering rate 35-40% of second of rolling, the calendering rate 40-50% of last rolling；Wherein coating processing method is as follows: being made using lead
For anode, one layer of hard chrome, cathode current effect is electroplated in roll in the tank liquor containing chromic anhydride, negative divalent sulfate ion and catalyst
Rate 30%-40%, chrome layer thickness control is in 8-10um, and chrome layer hardness is in HV900-1200.
In the present embodiment, ROLLING OIL heat is carried out in the wide edge range of band using edge thermal jet system in the operation of rolling
It is sprayed onto strip side portion and working roll region, thermal jet quantity spray head is 4-5, and the temperature whole-process control of thermal jet is at 105 DEG C -115 DEG C；
The target velocity of mill product outlet is 1050m/min-1200m/min.
In the present embodiment, chromic anhydride and sulfuric acid ratio 100:1, catalyst concn 10%.
The method of the production efficiency and surface quality of strips of the raising cold rolling aluminium alloy strips tank material of the present embodiment, is compared
Rolling mill practice in front of has the advantage that
1) production efficiency of unit time improves: the frequency of roll change is reduced using the finished product working roll of coating, before the every fortune of milling train
Row 300km replacement is primary, replacing construction 30min, can reach at least 1500km replacement now once, save roll changing time
120min, while mill speed is increased to 1050m/min by 950m/min before, averagely speed-raising 10.5%.
2) compare Fig. 2 and Fig. 1, roll carries out surface layer and applies plating, and the surfacing of roll is bright and clean to have no strip lines
Surface, and the RPC value of roller surface entirety becomes smaller after coating, makes the performance quality for obtaining tank material and surface quality more
It is excellent, work roll thermal crown variation range is narrowed down to by 1.0-2.5% by existing 1.2-2.0%, roll thermal crown section by edge thermal jet
Narrow so that the whole template of the band rolled is reduced to equilibrium, and then ensure that the performance quality of strip product, and roughness
It slowly reduces so that band obtains uniform surface, the broken wall problem in subsequent tank material process has also obtained effective solution
Certainly.
Finally, it should be noted that the foregoing is only a preferred embodiment of the present invention, it is not intended to restrict the invention,
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art, still may be used
To modify the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features.
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in of the invention
Within protection scope.
