Abstract

Abstract: Based on the experimental data and geometric model for the experimental air cushion furnace from the State Key Laboratory of Rolling Technology and Continuous Rolling Automation of Northeastern University, the Ansys Fluent software was used to construct the air cushion furnace floating simulation platform, and the effects of air cushion furnace inlet air volume, strip floating height, fluid temperature and nozzle structure on the copper strip floating behavior were analyzed. The results show that the floating height of the strip is conducive to the stable floating of the strip in the range of H=80-180mm. The higher the temperature, the lower the pressure of the strip, and the increase in the inlet air volume weakens the pressure lifting effect. Under high temperature conditions, the possible fan power fluctuations have little effect on the strip pressure, which is conducive to stable floating of the strip. The optimized inclination angle of the slit nozzle from 30° to 60° is conducive to improving the uniformity of strip pressure distribution, but will reduce the pressure on the strip.
