Abstract: A work roll cooling apparatus for a rolling mill includes: at least one chock (200) which is configured to support a work roll (100) in the rolling mill. The work roll (100) has an axis (X) about which it is rotatable. A shroud (300) so positioned adjacent the work roll rolling surface (100a) when the roll is in use to provide a cooling space within which a coolant is brought into contact with the work roll (100). The shroud includes a first part (301) disposed on the chock (200) to provide a predetermined gap (G) between the first part (301) and the work roll (100), a second part (302), and a connection for releasably connecting the first and second parts (301, 302). In a connected condition, the first and second parts (301, 302) are joined to provide the cooling space within the shroud (300), and in a disconnected condition, each of the at least one chock (200), the first part (301) of the shroud (300) and the work roll (100) may be axially removed from the rolling mill and the second part (301) of the shroud (300).

Abstract: Adjustable width rolls are preferably used for rolling, for example, insides of H-beams of various sizes without exchanging horizontal rolls of a rolling mill. Each of the adjustable width rolls includes a roll shaft rotatably and axially movably supported relative to the rolling mill, and axially adjustable sleeve roll fixed to the roll shaft, and an axially stationary sleeve roll mounted on the roll shaft to be axially slidable but against rotatable relatively to the roll shaft. The adjustable width roll further includes an axially adjustable roll fixedly supported by the axially adjustable sleeve roll to form substantially one half of a rolling barrel of the adjustable width roll, an axially stationary roll fixedly supported by the axially stationary sleeve roll to form substantially the remaining half of the rolling barrel of the adjustable width roll, and a driving mechanism for driving the roll shaft in axial directions of the roll shaft.

Abstract: The invention relates to a method and an installation for hot-rolling strips using a reversible Steckel rolling frame (8), each side of which is equipped with a respective furnace coiler (9, 10) and a driving mechanism (17,18), provided between the furnace coiler (9, 10) and Steckel rolling frame (8). The aim of the invention is to crop particularly thin, hot strips. To achieve this, the strip is cropped during the reversible rolling process by a single pair of flying cropping shears (20), positioned between one of the driving mechanisms (17) and the Steckel rolling frame (8). The cropping shears comprise in particular a drum blade.

Abstract: This disclosure relates to a roll changing device for a rolling mill including two side shifting platforms arranged in front of the mill, each having a pair of tracks for supporting a pair of rolls, one pair having been removed from the mill to be replaced by the second pair once the first pair is side shifted away from the front of the mill to position the second pair in front of the mill. Each platform also includes an opening for receiving a gear rack arranged to have its teeth projecting upwardly. On the side of the platforms remote from the mill a carriage is arranged having a motor driven pinion that engages an extension of one of the gear racks of the platforms when arranged in front of the mill, the carriage being employed to push and pull a pair of rolls to and from the mill. When not in use, the gear racks of the platforms are covered by plates selectively movable over the openings.
