Abstract：The floater-type heat treatment technology is an important way to product aluminum alloy with high surface quality and performance. And the stable control of the strip tension is one of the key links to realize the application of the technology. Based on a heat treatment line of aluminum alloy automobile sheet in a plant，the tension control technology was systematic researched. The architecture of the tension control system for the production line was put forward，and the tension control strategies were presented，which were applied in the large industrial production. The tension control system was stable and accurate，which met the actual needs of the industrial production. It can provide a solid foundation for the stable production of aluminum alloy automobile sheet.
