Abstract

Hot rolled steel prods. leaving the last stand of a rolling mill are cooled from a temp. above the austenite transformation point by passing the prods. through a series of longitudinally extending water troughs. The series is divided into sequential stages, each of which includes at least two troughs. The water supply to the troughs of each stage is controlled independently of the supply to troughs of other stages. The prods. are subsequently cooled in air. Ancillary trough sections are positioned adjacent the commencement of the second and subsequent stages. Air may be passed through the ancillary trough section to provide a stripping action and sweep away water clinging to the prod. passing through the troughs. The prods. cooled may include rod, bar or billet.
