Water Modeling Evaluation of Metal Delivery in a Twin Roll Strip Caster Using Pool Level and Residence Time Distribution Measurements

Abstract

A quantitative methodology that uses a water model to evaluate fluid flow of delivery systems under various operating conditions in the pool of a twin roll strip caster is presented. The measurements of two parameters are involved: level fluctuations of the pool and residence time distribution (RTD) of the fluid near the free surface. It is shown that a nozzle geometry that produces small level fluctuations and short residence times can be identified.
