What Should We Do if the Aluminum Extrusion Machine Does Not Produce Hard Enough Aluminum?

When we see the problem that the hardness of aluminum products produced by aluminum extruder is not enough, we should be able to think of the aging. At present, general aging is divided into two kinds: one is natural aging, the other is artificial aging. When the aluminum is extruded by the aluminum extruder, the hardness is very low before aging, and it can not be used as a finished product. Today, we will take you to understand the solution of insufficient aluminum hardness.


Ⅰ.The process of producing aluminum by aluminum extruder requires special attention


ⅰ.Temperature control of aluminum bar: the raw material of forging aluminum extruder is aluminum bar. Temperature measurement should be carried out on the aluminum bar before extrusion.


ⅱ.Online quenching process: solid solution quenching is the basic premise of aging, and it is meaningless without solid solution quenching aging.


So that, in the aluminum extruder outlet, it should according to the aluminum bar brand, profile wall thickness, extrusion speed and quenching equipment conditions to choose the online quenching process (wind quenching, wind-fog quenching, water quenching, etc.) to ensure that the quenching cooling rate in line with the alloy quenching sensitivity requirements.


ⅲ.Aging furnace temperature setting and control: usually, there is a certain error between aging furnace temperature and aging furnace table temperature. The table temperature should be set according to the actual temperature of the furnace, and pay close attention to the aging furnace temperature fluctuations.


ⅳ.Aging insulation: aging should be carried out in strict accordance with the process requirements, and insulation time should be appropriate to prevent under-aging or over-aging and resulting in insufficient hardness.


Ⅱ.Aluminum extruder frame loading, and loading furnace


ⅰ.The extrusion frame can not be too dense, there should be an interval between the material and the material, especially the small material and thick material without ventilation. When the pipe material and small material and sheet material are loaded together in a frame, the pipe material should be put below, which is conducive to the aging circulation air supply.


ⅱ.Before loading furnace, other special alloy and ordinary 6063 alloy should be separately loaded and aging, because if it should be with the furnace aging time, it is necessary to use the special alloy process.


The aluminum profile aging furnace involved in this problem is one of the auxiliary equipment of aluminum extruder. If you have a problem with aluminum extruders, you can consult us directly.
