FIELD: metallurgy.

SUBSTANCE: mill comprises a frame in which there is a working stand with rolls, a drive mechanism connected by a housing to the frame and by connecting rods to the working stand, front and intermediate cartridges and a main drive located on frame, which is connected to the input shaft of the drive mechanism by a coupling. The working stand with rolls has the ability to reciprocate along the frame guides. The main drive frame is rigidly connected to the body of the drive mechanism by means of a protrusion on its end face with a bearing surface and a groove with a projection on the side of the body of the drive mechanism. The coupling is made in the form of a gear sleeve and a gear block engaged with it, fitted with interference, respectively on the output shaft of the main drive and the input shaft of the drive mechanism or on the input shaft of the drive mechanism and the output shaft of the main drive.

EFFECT: increased reliability and durability of the equipment as a result of increasing the accuracy of alignment of the shafts to be connected.
