铝合金的热处理特点是要求加热温度准确,同时还必须保证炉膛内各点温度均匀。对于铸造铝合金,其热处理工艺规定的淬火加热温度上下限在±5℃以内。铝合金热处理的另一特点是要求经过加热和保温后的工件能迅速淬火冷却,以避免工件在空气中停留过长,导致温度降低而影响热处理质量。根据不同的铝铸件,要求淬火操作时间必须在5～20秒内完成。针对上述要求,我们设计制造了一台炉内空气强
Aluminum alloy heat treatment is characterized by the requirements of heating temperature is accurate, but also must ensure that the furnace temperature at each point evenly. For cast aluminum, the heat treatment process provides the upper and lower quenching temperature within ± 5 ℃. Another feature of aluminum heat treatment is required after the workpiece is heated and heat can be quenched and quenched to avoid the workpiece in the air to stay too long, resulting in lower temperature and affect the quality of heat treatment. According to different aluminum castings, quenching operation required time must be completed within 5 to 20 seconds. In response to the above requirements, we designed and manufactured a strong furnace air
