First，the process characteristics of aluminium alloy automotive sheet pre-treatment and the working principle of the air cushion furnace were introduced. The process location and irreplaceable role of air cushion furnace in the aluminium alloy automotive sheet production was pointed out after the difficulty and key point in the whole production process of the automotive sheet were studied. Then development process of air cushion furnace line of aluminum alloy sheet was reviewed ，summarized and divided to two stages. Based on the research status of the air cushion furnace，the key technology of it was analysed，and research key points on process， equipment and control models of air cushion furnace for aluminium alloy automotive sheet in future were put forward. As the rapid develop of the automotive industry，it will be certainly come that the new upsurge of the research and application of air cushion furnace for pretreatment of aluminum alloy automotive sheet.
