Abstract

A mathematical model has been developed to predict the temperature distribution in a moving strip of steel cooled by an array of planar water jets. Experimentally determined nucleate boiling and analytically obtained single‐phase convection and film boiling heat transfer coefficients are used as convective boundary conditions, and thermophysical property variations of the steel with temperature are considered in the analysis. The model equation for the strip temperature distribution is solved numerically, and the model is validated by comparing predicted coiling temperatures with measurements obtained on the runout table of a steel mill.
