摘要： An apparatus changes rollers of a straightening machine. The straightening machine contains a plurality of cantilever roller shafts for receiving the rollers. The apparatus contains at least a trolley having a device for supporting an entire set of upper and/or lower rollers to be installed in or taken off from the straightening machine. The apparatus further has at least two vertical plates spaced apart horizontally, a device for releasably securing the plates to the trolley, and an actuator connected to the plates and intended to be received in first passages defined in the straightening machine. The actuator is able to reversibly displace the plates and the trolley between a first position wherein the plates and the trolley are close to the straightening machine and a second position wherein the plates and the trolley are spaced apart from the straightening machine.

摘要： A method and a device for releasing a tube during a rolling process in a three-roll rolling stand in case of an emergency. The roll holder cartridge (3) has a longitudinal open slot (10) at the yoke support of the vertical axis roll so as to remove the roll holder cartridge according to a direction coinciding with the horizontal axis of the yoke support of the vertical axis roll while the support remains anchored to the fixed structure in the stand of the roll mill. In case of routine maintenance, the cartridge (3) is pulled out laterally with the yoke support of the vertical axis roll anchored to the cartridge itself as the other roll supports.

摘要： The invention relates to a rolling mill defining a rolling axis and comprising rolling stations. At least one rolling station comprises a fixed structure, a roll-holder cartridge and three actuators. The cartridge is connected removably to the fixed structure and comprises three rolling rolls. The rolls are movable radially and rotatable about three respective axes. Three actuators of the single-stroke type are mounted on the fixed structure and comprise pistons movable along respective radial axes to impart a force on the rolls for rolling an article. Three gearmotors provide the rolls, by means of spindles, with the torque for feeding the article along the rolling axis. When two pistons are completely retracted, a path is created free from obstacles allowing the cartridge to pass out laterally. Then, one spindle may be subject to a rotation-translation to be removed from the path, the respective gearmotor being fixed on its base.

摘要： Disclosed is a milling device for inline-rolling a steel band which is produced especially by means of a twin-roll continuous casting process. Said milling device comprises at least two rolling units (20, 30) with working rolls (21, 31) that mill the steel band (11) and support rolls (22, 32) which support said working rolls. The working rolls and support rolls are rotatably mounted in bearing housings (23, 24, 33, 34). At least two rolling units (20, 30) are disposed successively in a monolithic or multipiece frame structure (15) such that the rolling temperatures between the rolling units differ only slightly while a simple and inexpensive design is created.
