Abstract
The invention discloses a manufacturing method for a ceiling aluminum base material. A cast-rolled strip blank is coldly rolled, annealed, withdrawn and straightened as well as packaged in sequence, wherein in the cold rolling treatment process, the manufacturing method comprises the following steps: first, rolling the cast-rolled strip blank to a thickness of 6.5 mm, 4.5 mm, 3.0 mm and 2.2 mm in sequence; and then carrying out immediate annealing treatment on the 2.2 mm thick cast-rolled strip blank; and finally, rolling the cast-rolled strip blank treated through immediate annealing to a thickness of 1 mm. Experiments verify that a crystal grain structure in a finished product is more uniformr through selecting proper cold rolling pass distribution, a proper immediate annealing thickness and an annealing method, the bending performance of the finished product can satisfy machining requirements and a purpose of manufacturing the aluminum base material satisfying deep machining requirements by using the cast-rolled strip blank is achieved.

Summary of the invention
In view of this, the invention provides a kind of production method of furred ceiling aluminium base, satisfy the purpose of the aluminium base of deep processing requirement to realize utilizing cast-rolling stock to produce.
For achieving the above object, the invention provides following technical scheme:
A kind of production method of furred ceiling aluminium base is carried out cold-rolling treatment, anneal, straightening and packing successively to cast-rolling stock, and cold-rolling treatment may further comprise the steps:
It is 6.5mm thickness that step 1) is rolling to thickness with cast-rolling stock;
Step 2) cast-rolling stock of 6.5mm thickness being rolling to thickness is 4.5mm;
It is 3.0mm that step 3) is rolling to thickness with the cast-rolling stock of 4.5mm thickness;
It is 2.2mm that step 4) is rolling to thickness with the cast-rolling stock of 3.0mm thickness;
Step 5) is carried out the process annealing processing to the cast-rolling stock of 2.2mm thickness;
It is 1 millimeter that step 6) will be rolling to through the cast-rolling stock that process annealing is processed thickness.
Preferably, in above-mentioned production method, utilize thermojet formula air cushion furnace that cast-rolling stock is carried out process annealing and process.
Preferably, in above-mentioned production method, cast-rolling stock is specially the 3004H24 aluminium.
The invention provides a kind of production method of furred ceiling aluminium base, cast-rolling stock is carried out cold-rolling treatment, anneal, straightening and packing successively.Wherein, in the cold-rolling treatment process, at first, with the thickness of cast-rolling stock rolling successively be 6.5mm, 4.5mm, 3.0mm and 2.2mm; Then, the cast-rolling stock of 2.2 mm thick carried out the process annealing processing; At last, will be rolling to thickness through the cast-rolling stock that process annealing is processed is 1 millimeter.
Through verification experimental verification, by the cold rolling pass distribution of selecting to be fit to, process annealing thickness and the annealing way that is fit to, so that the grain structure of finished product inside is more even, the bending property of finished product can satisfy the processing needs, has realized utilizing cast-rolling stock to produce and satisfy the purpose of the aluminium base of deep processing requirement.
