DEVICE FOR DIRECTING THE FLOW FOR COOLING OF ROLL OR METAL STRIP Russian patent published in 2016 - IPC B21B27/10 

FIELD: technological processes.

SUBSTANCE: invention relates to rolling. Device (1) for directing the flow of cooling medium in the device for cooling of roll and metal strip includes hollow body (3), which passes at least part of the roll or metal strip, as well as pipe (5), which is located in hollow body (3) and passes in direction (B) width of the roll or metal strip. Higher efficiency of cooling by creating the favourable flow of cooling medium is ensured by the fact that hollow body (3) is divided in direction (B) width of the roll or metal strip into several chambers, and pipe (5) includes holes (9) for introduction of cooling medium in hollow body chamber (3), and chambers in each case include hole for ejecting coolant from hollow body (3). Chambers switch formed between the inner wall of hollow body (3) and pipe (5) channel (12) to direct cooling medium from holes (9) of tube (5) to the hole for ejecting coolant from hollow body (3), whereupon the cross-section of channel flow (12) converges, at least on its end located downstream.

EFFECT: higher efficiency of cooling by creating the favourable flow of cooling medium.
