Abstract

Highlights: Systematic experiments were carried out on a pilot scale run-out table using industrial size jets. A heat transfer model is proposed for jet impingement cooling of steel plates. The proposed model maps boiling curves at different positions on the plate surface. Abstract: The cooling pattern employed on the run-out table during steel processing highly affects the final microstructure of hot-rolled steel products and thus their final mechanical properties. This paper describes a strategy to develop a mechanistic heat transfer model for cooling of steel based on systematic experimental studies. Experiments were carried out on a pilot scale run-out table facility to investigate the cooling behavior of stationary steel plates. Based on the experimental results, a model is proposed that takes into account boiling heat transfer mechanisms to calculate heat fluxes on stationary plates during jet impingement boiling.
