| Abstract: |
| The influence of parameters of a new strip air-cushion heat treatment equipment, such as: injection pressure of jet flow nozzle, air speed, air temperature and strip tension on floating height, floating stability and heating uniformity was studied. On this basis, dynamic floating technique and cascade-cooling technique were developed using FEA and mathematic modeling. Therefore, the poor floating stability, low thermal efficiency and uniformity of traditional air-cushion furnace and quenching equipment were solved. Research results show that adopting new type equipment and techniques, the floating lift force and heat exchange homogeneity increase nearly twice, the strip flatness after quenching is less than 25I. |
