Liaoning industrial aluminum profile, alias: industrial aluminum extrusion material, industrial aluminum alloy profile, industrial aluminum profile is an alloy material with aluminum as the main component, aluminum rod is hot melted and extruded to obtain aluminum materials with different cross-sectional shapes, but the proportion of added alloys is different, and the mechanical properties and application fields of the industrial aluminum profile produced are also different. In general, industrial aluminum profiles refer to all aluminum profiles except for building doors and windows, curtain walls, indoor and outdoor decoration and building structures.
Selection of raw materials
Liaoning industrial aluminum profile is an industrial frame profile obtained by heating aluminum rods through die extrusion molding, while aluminum rods are cast through aluminum ingots, which are called industrial aluminum raw materials. The raw materials will directly affect the performance of industrial aluminum products.
The production of aluminum rods requires high technical requirements and industry standards to ensure the product performance of industrial aluminum profiles; aluminum rod casting production should note the following points:
①: content of active impurities;
②: Alloy composition;
③: melt superheat temperature;
④: diversion mode;
⑤: motion of melt relative to crystal face;
⑥: cooling rate;
⑦: speed of casting 6063 aluminum rod
Aluminum bar heating
The heating treatment of aluminum rod should ensure the temperature control, extrusion discharge temperature, online quenching temperature and so on.
mold design
Liaoning industrial aluminum profile is a product formed by extrusion of aluminum rods through a die after heating, while the die is an appliance with high-precision specifications designed according to requirements to extrude profile products with required specifications and sections. The following points should be paid attention to in the design and maintenance of the die:
The structure involved in the mold to meet the production needs, but also in line with the physical mechanics of common sense, to ensure that the production of products can achieve the performance of the use. The selection and hardness of the mold should be appropriate to avoid deformation, scratches and other hard injuries in the process of extrusion profiles, affecting product quality. ③The mold should be cleaned and inspected frequently. If there is a problem, it should be repaired in time to avoid scratches, burrs and other hard injuries during the extrusion production process, which will seriously affect the quality of industrial aluminum products.
Industrial Aluminum Profile Extrusion
At present, the extruder standard used for 6063-T5 industrial aluminum profiles is between 1300 tons and 1600 tons, and the above standards can meet the normal production of 6063-T5 series industrial aluminum profiles. Industrial aluminum extrusion process pay attention to the elements:
① Temperature control: For extrusion production, extrusion temperature is a basic and critical process factor. Extrusion temperature has a great influence on product quality, production efficiency, die life and energy consumption.
② Extrusion speed: The extrusion speed must be carefully controlled during the extrusion process. Extrusion speed has an important influence on deformation heat effect, deformation uniformity, recrystallization and solution process, mechanical properties and surface quality of products.
Straightening correction of industrial aluminum profile
Industrial aluminum extrusion molding after there will be a specific deviation, after forming to use straightening machine straightening correction, just extrusion molding of industrial aluminum profile correction to the required tolerance range, straightening correction must be completed by straightening machine to ensure its accuracy.
artificial aging
Extrusion production of aluminum profiles, without aging before the low hardness, can not be used as a finished product, therefore, in general, must be aging to improve strength.
Control of production process:
① Ingot temperature control: the temperature of the ingot shall be measured before extrusion, and the ingot can be produced after meeting the process requirements.
On-line quenching process: solid solution quenching is the basic premise of aging, there is no solid solution quenching aging is meaningless. Therefore, the online quenching process (wind quenching, wind-fog quenching, water quenching, etc.) should be selected according to the ingot grade, profile wall thickness, extrusion speed and quenching equipment conditions at the outlet of the extruder to ensure that the quenching cooling speed meets the quenching sensitivity requirements of the alloy.
③ Setting and control of the temperature of the tempering furnace: Generally, there is a specific error between the temperature of the tempering furnace and the apparent temperature of the tempering furnace. When setting the temperature of the tempering furnace, it should be set according to the actual temperature of the furnace, and pay close attention to the fluctuation of the temperature of the tempering furnace.
Liaoning industrial aluminum profile aging framing operation requirements
When the hanging material is fed into the furnace, the end of the aluminum profile and the air guide are controlled within 80~100mm.
2. It is not allowed to mix thermal insulation profiles and ordinary profiles in the confrontation frame
3. Aluminum profiles for thermal insulation curtain walls must be divided and installed in frames.
What are the extrusion production processes of Liaoning industrial aluminum profiles introduced by the editor today? That's all. I believe you have a better understanding of Liaoning industrial aluminum profiles and hope to help you.
