Blow-off air nozzles blow away the residual emulsion from roll gap and strip surface. Algorithm SIMPLY were used for the finite element numerical simulation for a representational air nozzle blow-off flow field near the roll gap in a cold-rolled skin pass mill. The working conditions of the blow-off flow field was the combination of gas pressure of 0, 2, 5 and 10bar and flip angle of 0°, 5°, 10°, 15°, 20° and 25°. The study provides a reference for control and optimization for the removal process of residual emulsion and design, manufacture, model selection and optimization for the related air nozzles.

Gas Flow Field

The numerical simulation calculation of air-assisted atomizer internal gas flow field is done, the distribution and changes of the nozzle inside flow field total pressure, velocity, and dynamic and static pressure are analyzed. The analysis shows that the total pressure loss is less; due to the effect of gas viscous, the high-speed air flow is formed vortex flow near the outlet nozzle and the mutual influence between the dynamic and static pressure. A new way is supported for optimizing the nozzle structure according to these studies.

The Relationship

Inner flow field numerical simulation model of conical nozzle was established. The relationship between conical nozzle structural parameters and its performance were obtained with simulation research. Simulation results show that the maximum outlet velocity of conical nozzle and the fluctuation range of radial velocity at outlet are determined by its convergence angle α and slenderness ratio Cp. With the increasing of α, the maximum outlet velocity of nozzle is increased at first and then reduced. When α is small, the fluctuation range of radial velocity at outlet is minute. When α is big, the fluctuation range of radial velocity at outlet is dramatic. With the increasing of Cp, the maximum outlet velocity of nozzle is increased at first and then reduced. When Cp is small, the fluctuation range of radial velocity at outlet is obvious. When Cp is big, the fluctuation range of radial velocity at outlet is minute. The optimal structural parameters of the nozzle are α = 40°, Cp =30°. Experiments of conical nozzle performance with different α were carried out. Experimental results show that ejection range of water jet is maximal when α = 40°.
