Strip Flotation Furnace for the Heat Treatment of Strips

Description

Application and Special Features:

Strip flotation lines are employed for the continuous horizontal heat treatment of aluminum strips, catering to the stringent requirements of the aerospace and automotive industries.

Both the furnace and the air cooling sections operate on the strip flotation principle: The running strip is supported on an air cushion as it undergoes heating, cooling and drying. The well-proven OTTO JUNKER nozzle system ensures high heat input and non-contact transport of the strip prioritizing gentle treatment of the product. The system’s efficient heat transfer contributes to high throughput rates, even with minimal line length. The centering properties of the patented centering nozzles ensure stable strip movement, even at low strip tension.

By means of the patented HiPreQ® quench, precise cooling rates can be set depending on strip thickness and alloy, with the mist quench function covering the cooling rates between water and air cooling, ensuring a low-deformation cooling of thin strips.
