- Abstract
- Traveling stability is necessary for a hot rolled strip on a run-out table before coiling in steel mills because it affects the process efficiency and the quality of the rolled products. This study proposes an air jet impingement system to reduce the hot strip wave that occurs during tensionless travel in a run-out table before the top end of the strip reaches the coiler mandrel. The finite element method was used to examine the pressure distributions on the moving strip associated with the parameters in the air jet systems. Experiments were carried out on a pilot-scale air jet impingement system to investigate the performance. The results show that the air impingement in the moving direction effectively reduces the strip wave, and the simulated results agree with the actual measurements and observations.
