2. Optimize the design and manufacture of aluminum extrusion die
Extrusion die is an important tool to ensure the shape and
dimensional accuracy of solar photovoltaic aluminum profile
products. The design and manufacturing quality of extrusion die is
an important guarantee to realize high quality, high yield, low
consumption, high efficiency and low cost of extrusion production.
Therefore, in order to produce high-precision photovoltaic aluminum
alloy profiles, it is necessary to optimize the design and
manufacture of extrusion die.
2.1 adopt advanced extrusion die manufacturing equipment
High precision advanced extrusion die processing equipment is the
prerequisite to ensure the metal extrusion die qualified.
Therefore, the production of photovoltaic aluminum alloy profiles
should use advanced mold processing equipment, such as CNC, slow
wire cutting, three-axis machining center, EDM center to improve
the machining accuracy and performance of the mold.
3. Chemical composition control
6063 aluminum alloy is used for production, and its chemical
composition control is shown in Table 1.
The practice shows that 6063 aluminum alloy has become an important
choice for the production of high precision photovoltaic aluminum
alloy profiles. 6063 Al Mg Si alloy can be strengthened by heat
treatment. The strengthening phase of the alloy is Mg2Si. The alloy
has good extrusion property, low quenching sensitivity, good high
temperature plasticity, wide quenching temperature range and low
critical quenching speed. Within the composition range of 6063
aluminum alloy specified in the national standard GB / t3190,
different values of chemical composition will lead to different
material characteristics. When the range of chemical composition is
large, the performance difference will fluctuate in a large range,
so that the comprehensive performance of the profile will be
difficult to control. In order to ensure the precision of
photovoltaic aluminum alloy profile, it is necessary to
The chemical composition of the alloy must be determined in strict
accordance with the enterprise control standard.
4. Smelting, casting and ingot homogenization process
4.1 smelting and refining process
The melting temperature is 720-760 ℃. When the temperature is above
720 ℃, high purity nitrogen is used to blow in refining agent for
15min, the amount of refining agent is 0.08% of the melt weight,
after refining, electromagnetic stirring is used for 15min, and the
liquid aluminum is allowed to stand for 20-30min. The chemical
composition of aluminum alloy solution shall be strictly controlled
for sampling inspection to make the material reach the required
4.2 casting process
Semi continuous direct water cooling casting method was adopted.
The direct water cooling method has the advantages of high cooling
intensity and high cooling speed, which can refine the casting
structure, increase the density of the structure, and improve the
mechanical properties and heat treatment effect of the ingot. The
casting temperature is 710-730 ℃, the casting speed is 50-70mm /
min, and the cooling water pressure is 0.1-0.3mpa. In order to
reduce the tendency of hot cracking and improve the chemical
composition of the alloy, Al Ti B wire was added online at the rate
of 1700-2000mm / min.
4.3 homogenization treatment of cast bar structure
In order to reduce and eliminate intragranular segregation of ingot
and improve the inhomogeneity of chemical composition and
microstructure, homogenization treatment was carried out on
aluminum alloy casting bar. The technical conditions are as
follows: heating the casting rod to 540-550 ℃, holding for 8-10h,
strong wind cooling and water mist cooling. Cooling should be
accelerated after homogenization annealing to ensure the color
uniformity after anodization.

The density of aluminum profile is only 2.7g/cm3, about one third
of that of steel, copper or brass (7.83g/cm3, 8.93g/cm3). Aluminum
exhibits excellent corrosion resistance under most environmental
conditions, including air, water (or brine), petrochemicals, and
many chemical systems.
Aluminum profile is often selected because of its excellent
conductivity. Aluminum is almost twice as conductive as copper by
Rate thermal conductivity
The thermal conductivity of aluminum alloy is about 50-60% of that
of copper. It is used to manufacture heat exchangers, evaporators,
heating appliances, cooking utensils, cylinder heads and radiators
Aluminum profiles are non ferromagnetic, which is an important
feature of the electrical and electronic industries. Aluminum
profiles do not self ignite, which is very important for
applications involving handling or contacting flammable and
Machinability of can making machine
The processing performance of aluminum profile is excellent. In the
process of deformation and casting of aluminum alloy, as well as in
various states after the output of aluminum alloy, the processing
characteristics change greatly, which requires a special machine
tool or process.
Specific tensile strength, yield strength, ductility and
corresponding work hardening rate determine the variation of
Aluminum is very recyclable, and the performance of recycled
aluminum is almost indistinguishable from that of natural aluminum.
