Abstract: The present application relates to a heat treatment unit, in particular a cooling hood, including a chamber with an inlet opening through which a gaseous cooling medium can be fed to the chamber, and a slot-shaped outlet opening through which the gaseous cooling medium can be discharged faster. The chamber includes a central chamber segment and a first and a second outer chamber segment extending from the central chamber segment, and both outer chamber segments have a cross-section tapering proportionally towards their distal ends, and a device for the heat treatment of hot-rolled long steel products.
