Heat transfer coefficients for the secondary cooling zones in a continuous casting with the effect of steel chemistry

Popis výsledku v původním jazyce

ArcelorMittal has developed on-line cooling models to predict the surface temperature distribution of slabs during casting. The model uses heat transfer coefficients experimentally determined by The Heat Transfer and Fluid Flow Laboratory of Brno Technical University (HeatLab Brno). The HeatLab?s standard practice is to determine these coefficients as a function of position under the nozzle, spray water volume, and surface temperature using austenitic stainless steel plates as the substrate. The measured HTCs accurately predicted the surface temperature for a wide range of carbon steels from about 0.04% to 1.0% carbon. While casting 3 % silicon steels on a CSP caster it was noted that the predicted surface temperature was significantly higher than theactual measured surface temperature. This anomaly led to the concern that some of the other grades being cast would also have greatly different HTCs than calculated when using a stainless steel substrate. To determine the effect of steel
