1, aluminum temperature setting and control: usually, warm temperatures with the table there were some errors when setting the table according to the furnace temperature and the actual temperature to be set, and pay close attention to temperature fluctuations.
2, aluminum heat aging: in strict accordance with requirements of the aging process, the holding time should be appropriate to prevent the over-aged and under-aged or cause insufficient hardness. Blank framed, mounted stove
3, aluminum extrusion framed not too close, to have spacing between the material and the material, especially the non-ventilated Aluminum Alloys small material, thick material to be bigger interval more, tubing and small material, sheet combined installed a box, aluminum tubing placed beneath it is a good time-circulating air.
4, aluminum furnace installed to 6xxx alloys and other special furnace installed separately from normal aging 6063, due to production reasons you really want the same heat aging, it is necessary to have access to special alloy subjected to aging process.
Out of aluminum extrusion, without low hardness before aging, not as a finished product to use, so, in general, must be to improve strength after aging. Typically, aging can be divided into two kinds of natural aging and artificial aging, aluminum 6xxx aluminum production now or in the future basically dominated.
