A work roll cooling apparatus for a rolling mill includes: at least one chock () which is configured to support a work roll () in the rolling mill. The work roll () has an axis (X) about which it is rotatable. A shroud () so positioned adjacent the work roll rolling surface () when the roll is in use to provide a cooling space within which a coolant is brought into contact with the work roll (). The shroud includes a first part () disposed on the chock () to provide a predetermined gap (G) between the first part () and the work roll (), a second part (), and a connection for releasably connecting the first and second parts (). In a connected condition, the first and second parts () are joined to provide the cooling space within the shroud (), and in a disconnected condition, each of the at least one chock (), the first part () of the shroud () and the work roll () may be axially removed from the rolling mill and the second part () of the shroud ().

Work roll cooling apparatus and method

An apparatus and a method provided for spraying a coolant to a work piece include a coolant feed line, at least one delivery nozzle for delivering the coolant, and shielding means which surround at least part of said delivery nozzle. The shielding means are arranged with the work piece to form an essentially closed space, and said shielding means includes exhausting means for exhausting gas from the essentially closed space, and means for keeping the outside of the shielding means at a temperature above the dew point.
