摘要 A method for cooling rolled stock downstream of a given roll pair of a rolling mill having connected thereto a stock cooling section comprising at least one cooling tube (2), a liquid-coolant jacket (3) surrounding the tube, an external guide tube (8) leading from a given roll pair to the at least one cooling tube (2), and an internal guide tube (4) located in the cooling tube. The method comprises the steps of forcing the liquid coolant from the jacket into the external guide tube (8) in countercurrent with the direction of stock movement and into the internal guide tube (4) concurrently with said stock movement. In accordance with the novel features of the invention, immediately the stock leaves the nip of the given roll pair it is passed into the external guide tube (8) of a first cooling tube in line, this guide tube being placedin direct connection with said roll nip. The arrangement is such that liquid coolant can be forced from the jacket (3) into the external guide tube (8) in a controlled manner and from there into the roll nip while, at the same time, forcing liquid coolant from the jacket (3) in a controlled manner into the internal guide tube (4).
