![عکس صفحه اول مقاله: The pressure loss and ribbon thickness prediction in gap controlled planar-flow casting process The pressure loss and ribbon thickness prediction in gap controlled planar-flow casting process](/preview/png/798374.png)
The dynamics of the single roller planar-flow casting (PFC) process is modeled using mass balances and the Bernoulli equation to formulate the final analytical solution. The emphasis is focused on the gap controlled PFC process and the prediction of ribbon thickness with given PFC process parameters. The experimental results show that the pressure loss is significant when the flow turns its direction from the nozzle slot into the upstream region of puddle. By introducing the pressure loss into a PFC process model, the predicted ribbon thickness is qualitatively in good agreement with the experimentally measured ribbon thickness in large scale production of amorphous ribbons.
► The dynamics of the gap controlled planar-flow casting process is modeled.
► The pressure loss is a significant factor influencing the final ribbon thickness.
► An empirical formula from prior work is applied to predict the ribbon thickness.
► The predicted thickness is qualitatively in agreement with the measured thickness.
