Abstract
A method and a device adjust the cooling of a steel strip in an annealing or galvanization phase. The device is suitable for the forced cooling of a steel strip continuously running in a plant adapted for the continuous annealing or the continuous tempering galvanization. The device has at least one exchange member for transferring the heat of the steel strip to cooling water and includes an outlet for the cooling water thus heated up. At least one cooling unit is provided and has a sealed enclosure connected to the outlet of the exchange member and includes at least one outlet to a Venturi effect device such as a vapor outlet ejector and in which the cooling water itself is subjected to a vacuum-vaporization cooling. An auxiliary outlet of the sealed enclosure is connected to an inlet of the exchange member.
