Abstract (en)
[origin: EP0111985A2] 1. Process for cooling a moving thin steel strip by spraying a refrigerant onto the surface of the strip, in which the said steel strip is subjected to a low intensity cooling phase followed by a high intensity cooling phase, characterized in that the said low intensity phase is carried out with a heat exchange coefficient less than or equal to 3 kW/m**2 degrees C and in the said high intensity phase is carried out with a heat exchange coefficient greater than 3 kW/m**2 degrees C, and in that the said low intensity phase is interrupted when the strip has reached a temperature of between 600 degrees C and 350 degrees C.
