Abstract: In order to study the operation mechanism of industrial air flotation annealing furnace, the mechanical structure and control system are developed and the flotation height of web is established using the heat treatment zone as a subject. According to the operation process, the experimental air flotation platform can stabilize one series aluminum strips with the thickness of 0.3~2mm to the float heights between 0~200mm. The hybrid flotation height model can predict the flotation height of the strips precisely, whose accuracy is ±3mm. The structure and running process of the developed air flotation platform are similar to those of present industrialized air flotation furnaces structure. The research provides good theoretical guidance to industrialize air flotation oven.

Key words: test platform of air flotation furnaces, flotation height, structure design, control system design, flotation height model
