How to make the material hardness of aluminum profile manufacturer reach the process standard
Apr 27, 2022
1. formulation and operation of timely furnace temperature of manipulator aluminum profile: generally, there is a certain deviation between the timely furnace temperature and the timely furnace surface temperature, and the surface temperature shall be set according to the specific temperature of the furnace.
2. timely heat preservation of aluminum: strictly implement the processing process requirements, timely heat preservation, moderate heat preservation time, and avoid insufficient hardness due to insufficient time or out of date. Embryo material framing and furnace loading
3. The aluminum extrusion frame should not be too dense, and there should be a gap between the materials, especially for the batching and thick materials that are not naturally ventilated. When the tube blank, batching and plate are combined into a frame, the lower side of the tube blank is beneficial to the ventilation of the aging cycle system.
4. The special aluminum profile finishing shall be separated from the general 6063 aluminum alloy for furnace aging outside the aluminum furnace. When the manufacturing factors really need the same furnace aging, the special aluminum alloy technology shall be used for aging.
The aluminum alloy profile produced by extrusion has a slightly lower hardness before aging and cannot be used as a finished product. Therefore, generally speaking, it is necessary to improve the compressive strength through aging. Generally, aging can be divided into natural aging and manual aging. At present, most of the 6 aluminum alloy profiles are produced or the latter is dominant.
The hardness of aluminum alloy profile is closely related to the material and aging solution. If the hardness is unqualified, it is not necessary to change the secret recipe and the model. For example, the aluminum material in the national standard 6063t5 has a hardness of 12. To get a hardness of 13.14.15, only the 6063a, 60616 or 6005T5 with higher silicon can be used. However, if the hardness comes up, it is likely to endanger the beauty of surface treatment. Naturally, there are other areas to pay attention to.
