PRELIMINARY COOLING SYSTEM WITH CONTROLLED INTERNAL ADJUSTMENT Russian patent published in 2018 - IPC B21B45/02 

FIELD: metallurgy.

SUBSTANCE: invention relates to the moved metal strip (2) cooling area, having subjected to the hardening liquid coating. Unit is equipped with two gas coolers (11, 12), each of which is designed to cool down the tape (2) one side and has nozzles or slots (15) on its inner side, at that, each cooler (11, 12) along its length is divided into at least first section (13) and second section (14) in series arranged along the belt (2) movement direction, transversely divided relative to the belt movement by the internal adjusting device (7, 8) configured to change the flow / pressure parameter in the corresponding first and second sections, at that, the internal adjusting devices (7, 8) are configured to control the gas flow / pressure parameter between the sections, with the different cooling modes by means of diffusers formation in the sections.

EFFECT: invention provides the possibility of the belt different parts flexible and balanced cooling.
