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.
