The Manufacturing Process of 3003 H14 Aluminum
3003 aluminum plate is a typical 30000 series aluminum sheet. Its main alloy element is Mangenese, of which the content is 1.0-1.5%. Iron and silicon are impurities, which need to be controlled within <1.85%. Copper can increase the tensile strength. Zinc can improve the welding performance of the alloy.
H14, H24 and O are the common tempers of 3003 aluminum sheet. 3003 h14 aluminum has good corrosion resistance, medium strength and high high plasticity, excellent formability and good welding performance. The alloy is mainly used in pressure tanks, storage tanks, chemical equipment, aircraft fuel tanks, heat exchanger,etc.
There is the production process of 3003H14 aluminum sheet:
1. Melt
The needed equipment is a gas stove. The Melting temperature is 720~760℃.
2. Casting
The needed equipment is a semi-continuous casting machine. The casting requirements include:
Casting temperature: 710-720℃
Casting speed: 55~60mm/min
Water pressure: 0.08~0.15MPa
Ingot size: 300mmx1280mmx2500mm
3. Homogenization
The needed equipment is an electric resistance furnace. The processing temperature is 495℃/19h.
4. Milling
The milling machine is used to mill the surface 5 mm per side.
5. Surface cleaning
Wipe the surface with aviation gasoline.
6. Heating
Here we use the push type heating furnace. The heating requirements are:
Heating temperature: 480~520℃
The heating time: 10~12h
7. Hot rolling
We use high reversible hot rolling mill for the 3003 h14 aluminum sheet.
Rolling times: 13 passes
Plate thickness: 11.0mm
The initial rolling temperature: 480~510℃
The final rolling temperature: 380℃
Emulsion lubrication
8. Cutting
The cutting length is 3000mm.
9. Intermediate annealing
The annealing temperature is 400~450℃ and the heating time is 6~8h.
10. Cold rolling
The needed equipment is a high irreversible cold rolling mill. The cold rolling requirements:
Rolling times: 4 passes,
Plate thickness: 8.0mm
Rolling oil lubrication
11. Straightening
We need to check the surface condition of the straightened plate. If there is something wrong, we need to deal with it in time.
12. Sawing
The aluminum plate will be cut into the finished product size and we need to test the mechanical properties of the 3003 h14 thick aluminum plate.
13. Inspection
We need to inspect the surface and size of the 3003 h14 aluminum sheet according to corresponding standards.
14. Package
The usual package is pad paper and wooden box. If you have any special requirement, please tell us in advance.
