ã€China Aluminum Industry Network】When manufacturing and processing industrial aluminum extrusions, how to control the hardness is the key. If there is a slight failure, it will cause trouble for users. How to solve the problem of industrial aluminum extrusions with too low hardness? 1. The setting and control of the aluminum aging furnace temperature: Generally, there is a certain error between the aging furnace temperature and the apparent temperature of the aging furnace. When setting the table temperature, the actual temperature of the furnace must be set according to the actual temperature of the furnace. The market pays close attention to the fluctuation of aging furnace temperature. 2, aluminum aging insulation: to strictly follow the process requirements for aging, the insulation time should be appropriate to prevent the lack of timeliness or overtime and resulting in insufficient hardness. 3, aluminum extrusion frame can not be too dense, there must be a gap between the material and material, especially the non-ventilated small material, thick material spacing should be larger, tube material and small materials, when a box together , The tube is placed below this is conducive to aging circulation air. 4, before loading the aluminum profile 6xxx other special alloys and ordinary 6063 alloy separately loading furnace aging, due to production reasons must be with the furnace aging, to take special alloy technology to aging. Extrusion produced aluminum profiles are not rigid before ageing and cannot be used as finished products. Therefore, in general, they must be aged to improve strength. Generally, aging can be divided into natural aging and artificial aging. At present, production of 6xxx aluminum profiles is basically based on the latter.
