Height of Water Pool in the Roll Nip of Secondary Cooling Zone in Continuous Slab Caster: Application of Open Channel Hydraulics

Abstract In continuous casting of steel, the strand is cooled in upper part secondary cooling zone with water sprayed by nozzles towards surface. The accumulates nip lower roll a pair, forming pool which then drains off ends roll. present work, open channel hydraulics was applied for computation height between and slab casting. differential equation describing change spatially varied flow increasing discharge solved Runge–Kutta technique using as boundary condition at end nip. effects Manning friction factor n energy coefficient α were determined sets computation. It shown that hydraulic theory could predict profiles rolls to good approximation.
