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.
