PIPE COOLING APPARATUS Russian patent published in 2007 - IPC C21D9/08 C21D1/62 

FIELD: thermal processing, in particular, thermal reinforcement of pipes by heating of individual pipes in thermal department lines or for thermomechanical processing of pipes using rolling process heat.

SUBSTANCE: pipe cooling apparatus has casing having one side made in the form of central gear of differential planetary transmission gear with carrier formed as flange positioned on pipe with receiving funnel. Pipe has through openings positioned opposite to nozzles. Collectors are axially attached to toothed gears-satellites. Brush device is positioned for rotation within each of said collectors, said brush device being fixed on pin, whose free end portion is positioned for movement without rotation in slot provided on central gear, concentrically to main axis of transmission gear. Brush device is made spiral. Free end portion of its pin is connected to ratchet mechanism. Opening is provided in lower part of collector, with area of said opening exceeding by 3-5 times area of nozzle opening.

EFFECT: increased efficiency in controlled cooling of articles, and improved quality of articles by uniform cooling thereof.
