Definitions
- the cooling transition temperature is the temperature of the strip for which the cooling of the strip by the quench bath passes from a heat exchange through a continuous vapor film to a heat exchange through a discontinuous layer of vapor bubbles.
- the cooling rate goes from about 50 to 60 ° C / s for cooling with boiling water, to about 150 to 200 ° C / s for cooling with water to 80 ° C, in the case of a steel strip 0.8 mm thick.
- the surface-active substances added to the aqueous bath must also resist the aforementioned organic acids.
