How to solve the problem of low hardness of industrial aluminum profiles

by:Zeyi     2021-05-02
In the production and processing of industrial aluminum profiles, how to control the hardness is the key. A slight unqualified will cause confusion to users. Now share the following methods, welcome to exchange and learn! 1. The aluminum extrusion frame should not be too dense, and there should be a gap between the material and the material, especially the small and thick materials that are not ventilated, and the interval between the pipe material and the small material and the plate should be larger. , The tube material is placed below this is conducive to the aging cycle air supply. 2. Temperature setting and control: Generally, there is a certain error between the temperature and the apparent temperature. When setting the temperature, it should be set according to the actual temperature of the furnace and pay close attention to temperature fluctuations. 3. Aging and heat preservation of aluminum profiles: Aging should be carried out in strict accordance with the process requirements, and the heat preservation time should be appropriate to prevent under-ageing or over-ageing from causing insufficient hardness. 4. Before the aluminum profile is loaded into the furnace, other special alloys of 6xxx and the ordinary 6063 alloy shall be loaded separately for aging. When the aging is done in the same furnace due to production reasons, the special alloy process shall be used for aging.
What are the specifications of industrial aluminum profile profiles?
profiles are mainly divided into national standards and European standards, as well as light and heavy.  15 series of industrial aluminum profiles only have national standards but not European standards. There is only one profile in the   16 series.   20 series are divided into national standard and European standard, that is, 2020 industrial aluminum profiles are divided into national standard 2020 and European standard 2020. This series is not divided into light and heavy. There are many specifications of 30 series industrial aluminum profiles, not only light and heavy, but also national and European standards. There are many models of 3030 industrial aluminum profile profiles. For example, 3030 has light, very light, heavy, arc, etc., so You can ask the salesperson to recommend the appropriate aluminum profile model according to your different needs.   The 35 series is relatively simple, like the 16 series, there is only one.  40 series and 30 series industrial aluminum profiles are the same model classification. It can be said that 40 and 30 industrial aluminum profiles are two series that are commonly used and have more specifications.  The 45 series has only European standard, but there are many specifications, almost including light, standard, heavy, right-angle, arc and so on.   The 50 series is relatively simple. Similarly, there are no national standards and European standards. There are only two specifications, each of which is only divided into light and heavy.   60 series of industrial aluminum profiles are divided into national standard and European standard, but they are relatively simple. The same is divided into light and heavy. The difference is that this series also has a circular arc profile.  80 series also has a circular arc profile, and this profile is also divided into national standard and European standard.   Both the 90 series and the 100 series have only one specification, divided into heavy and light.
