1: material selection:

Industrial aluminium profile is acquired by heat extrusion aluminum rods industrial framework profiles, and aluminum rod is made of aluminium ingot casting, known as the industrial aluminum. Raw materials will directly affect the industry. Lu: xingcai products performance.

Aluminum rod production requirement of high technical requirements and industry standards, to ensure that the performance of industrial aluminum profile; Aluminum bar castings production should pay attention to the following:

1: active impurity content;

2: the alloy composition;

3: the melt superheat temperature;

4: transfer method;

5: the melt relative to the movement of the crystal;

6: cooling rate;

7: casting 6063 aluminum rods;

2: aluminum rod heating:

Heat treatment shall ensure that the temperature control of aluminum rod. If the temperature is too high or low temperature, it will directly affect the hardness of the final product. Therefore, must be strictly controlled in the process of heating and cooling temperature.

3Mould design:

Industrial aluminum aluminum rods by heating by mold out of the final product, and the mold is designed based on the requirements of high precision tools, used in extrusion has the required specifications and cross section profile products; The design of the mould and maintenance should be paid attention to the following:

1: mold structure involved must first meet the production requirements, and also must conform to the physical and mechanical common sense, to ensure that products can meet the using performance.

2: mold material selection and hardness should be appropriate, in order to avoid in the process of extrusion deformation and scratches, it will affect the quality of the final product.

3: must often clean and check the mold. If any problem, should be timely repair, in order to avoid scratch and burr appeared in the process of aluminum profile extrusion, serious impact on the quality of industrial aluminum.

4: industrial aluminum extrusion:

At present, the standard for 6063 - T5 industrial aluminum extrusion machine between 1300 tons to 1600 tons. The above standard 6063 - T5 series of industrial aluminum and can ensure normal production.

Industrial aluminum extrusion process matters needing attention:

1: temperature control for extrusion production, extrusion temperature is the most basic, the key technological factors. Extrusion temperature on the quality of our products and production efficiency and die life, energy consumption and so on all has very big effect.

2 extrusion speed: must be carefully controlled during the process of extrusion speed. Extrusion speed of deformation heat effect, deformation uniformity of solid solution and recrystallization process, mechanical properties of the product and the product surface quality has important influence.

3 on quenching: 6063 - T5 quenching is to keep dissolved in base metals of Mg2Si high temperature, and then quickly cooled to room temperature. Cooling rate is usually proportional to the strength of the reinforced phase. The most low cooling speed of 6063 alloy is 38 ° C/min, so is suitable for air cooling quenching. Change cooling intensity, fan and the fan speed can be changed by before straightening straightening product temperature dropped below 60 ° C.

Good thing

5: industrial aluminum alignment correction:

After the industrial aluminum extrusion, there will be some deviation. After molding, should be used to correct the straightener, new industrial aluminum extrusion should be corrected to the required tolerances. Must be straight. Straight machine, to ensure its accuracy.

6: artificial aging:

Extruded aluminum is not used as a finished product before aging, so usually must be aging in order to improve strength.

The production process control:

1: ingot casting temperature control: before the injection machine, should first measuring the temperature of the ingot casting, then the need to carry on the processing to produce the machine.

2: online quenching process: solid solution hardening is the basic premise of aging, no solid solution hardening, no significance. Therefore, we should according to the level of ingot casting, material thickness, the extrusion speed and quenching equipment conditions, the extruder of outlet to choose online quenching process (water quenching wind, the wind fog quenching, quenching, etc.). To ensure the quenching cooling rate. Satisfy the requirement of the alloy quenching sensitivity.

3: aging furnace temperature setting and control: usually, aging furnace temperature and the temperature on the surface of the aging furnace has certain error. Set the workbench temperature, should be set according to the actual temperature of the furnace, and pay close attention to the aging temperature of the furnace. Volatility.

4: insulation aging: should be in strict accordance with the technical requirements for aging, keep time should be appropriate, in order to prevent the aging of insufficient or excessive aging, lead to insufficient hardness.

Blanking, load the furnace:

1: extrusion box should not be too dense, should have a space between the material and the material, especially the small interval between material and thick material should not be ventilated, between material and small material and plate should be bigger. The following is good for aging period to supply air.

2: before installing the stove should be separated the 6063 special alloys with normal 6063 alloy for oven aging. Due to production, must adopt the special alloy process for aging treatment.

7: sandblasting oxidation process:

After extrusion, industrial aluminum extrusion has obvious stretch marks on the surface, and surface microporous relatively large, relatively coarse. Must be sandblasting processing. The impact of the corundum sand blasting process will lead to the surface of the aluminium profile. The structural changes in the structure, with the plastic deformation in the process of crystal slip, lead to the increase of dislocation density in the grain, and contour surface more smooth.

Industrial aluminium profile surface treatment according to the following steps:

1: sandblasting surface treatment;

2: surface pretreatment;

3: industrial aluminum degreasing process;

4: industrial aluminum etching process;

5: industrial aluminum alkali etching process;

6: the neutralization process;

7: industrial aluminum oxidation process;

8: industrial aluminum sealing process;

At present, many industrial aluminum market reduces the cost, reduces the industrial aluminum surface oxidation process, direct use silver oxidation treatment, surface for light silver, and the coating generally is lower than the industry standard 5-6 between mu mu (coating industry standard 10 mu mu to 12).

8: packing:

Due to the high quality industrial aluminium profile, the appearance of the overall aesthetics is very special, so after the packaging requirement is very strict, and the entire packaging process is divided into the following categories:

1: coating was carried out on the material surface to avoid scratches.

2: pearl cotton packing;

3: the outermost wrapped a layer of kraft paper, in order to avoid
