Optimization of the level sensor position for a continuous slab caster

The optimal position of the mold liquid level sensor for a continuous slab caster is experimentally studied in this work. To establish the optimal position, a 1:1/3 physical cold water model was employed. The water model was constructed in accordance with the Froude similarity criterion. The meniscus profile dispersion was evaluated at several volumetric flow rates and submerged entry nozzle (SEN) submergence depths. The liquid level measurements were taken with an ultrasonic distance sensor and recorded in a computer. The experimental results show a strong nonlinear correlation between the process parameters and meniscus fluctuations intensity.
