ROLL HAVING COOLING CONTOUR FOR CONTINUOUS CASTING OF METALLIC BAND Russian patent published in 2005 - IPC

FIELD: processes for continuous casting of metallic band, for example of aluminum and its alloy.

SUBSTANCE: invention includes group of inventions such as housing of roll of manufacturing plant, roll cooling method, roll of manufacturing plant and plant for continuous casting. Housing of roll includes cylindrical yoke and cooling contour. The last includes at least one main duct for supplying cooling agent, at least one main duct for discharging cooling agent, at least one distributing manifold, at least one discharge manifold. At least one distributing tube for communication of each manifold with respective main duct and large number of annular passages connecting supply and discharge manifolds. Said manifolds and annular passages are designed for providing contact of cooling agent circulating in cooling contour with inner surface of yoke for cooling it. Distributing and discharging manifolds are arranged alternatively in peripheral and lengthwise directions and they form geometrically ordered circuit under yoke surface. Manifolds of one row are mutually shifted by distance equal to 5 - 25 % of their length. Method comprises steps of cyclically changing direction of circulation of cooling agent in cooling contour at least of one roll.

EFFECT: enhanced uniformity, improved quality of cast metallic band due to minimized temperature difference in roll and lowered degree of thermal ovalization occurred in rolls at operation.
