dc.description.abstract	This paper reviews the quenching of a moving metal sheet with series of jets from a mold. Experiments were conducted on various samples and the temperature on the back side of the plate was measured using an infrared camera with high local resolution. An analysis method developed by the author was used to obtain heat flux as a function of temperature on the quenching side of the sheet in the steady state region, accounting for the thickness of the sheet. The analysis method is also less sensitive to experimental and numerical errors. The thermal history data is used in conjuncture with the analysis method in order to obtain the heat flux and surface temperatures. A study analysing the boiling curve and width of the wetting front is conducted for different metals with different mold moving speeds and initial temperature. The results are compared and analysed for identifying various influencing parameters during the continuous quenching process.	en
