Abstract：

In the hot forming process of aluminum alloy, heating solution plays an important role, but the heating efficiency of traditional radiant heating method is low to seriously affect the process beat. However, the contact heating has the characteristics of fast heating speed and uniform heating temperature. Therefore, the contact heating device was designed to heat high strength aluminum alloy sheets quickly, and the temperature distribution on the contact surface of device and the heating characteristics of high strength aluminum alloy sheets were studied. The results show that the heating device has a larger area of uniform temperature, which is suitable for solution treatment of high strength aluminum alloy sheets. Meanwhile, the time required for solution heating stage is reduced effectively by the contact heating mothed, and the heating efficiency of sheets is improved. The test results show that the high strength aluminum alloy billet is heated to the set temperature in 20 seconds, and the contact heating rapid solution of high strength aluminum alloy is proved to be a highly efficient solution treatment method for aluminum alloy.
