ã€China Aluminum Industry Net】1. Setting and Control of Aluminum Bar 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 should be used to set the table temperature. , and pay close attention to aging furnace temperature fluctuations.
2, aluminum rod aging insulation: to strictly in accordance with the process requirements for aging, the insulation time should be appropriate to prevent the lack of timeliness or overtime and result in insufficient hardness. The blank frame, furnace 3, aluminum rod extrusion frame can not be too dense, there must be space between the material and material, especially non-ventilated small material, thick material spacing should be larger, tube material and small material, plate When the materials are put together in one frame, the tube material is placed below so as to facilitate circulation of the air for a period of time.
4 Before the aluminum rod is loaded, the other special alloys of 6xxx and ordinary 6063 alloys are separately assembled and furnace-aged. Since the reason for production must be the same as the aging of the furnace, the special alloy is used to perform aging.
The 6061 aluminum rod produced by extrusion has a low hardness before ageing and cannot be used as a finished product. Therefore, generally speaking, it is necessary to increase the strength through aging. Generally, the aging can be divided into natural aging and artificial aging. At present, the production of 6xxx aluminum profiles is basically based on the latter.
