    摘要: A coupling is provided in which a coupling member and coupling sleeve of a rotary coupling for coupling a drive transmission to a rolling mill stand input shaft have mating taper threads which provide torsional rigidity and facilitate quick engagement and release. Engagement and release are effected by slowly turning the coupling half by means of the drive transmission while a brake device engages dogs on the coupling half to prevent the latter rotating. The coupling sleeve is flexibly attached to the flange by sheet metal laminate compensating elements but mobility of the sleeve is restricted by a support element on a shaft extension.

    摘要: An arrangement for inclined rolling of tube-shaped or bar-shaped rolling products comprises at least two rollers adapted to receive therebetween a rolling product so as to determine a longitudinal axis of the rolling product, the rollers are driveable and are rotatable about said longitudinal axis. The rollers have roller axes inclined at an inclination angle relative to the longitudinal axis, the roller axes being inclined in such a plane which, when considered in or against the longitudinal axis, extends parallel to the longitudinal axis at a radial distance from it, and a driving unit for driving the rollers. The driving unit includes a sun gear and drive gears provided with an axis-offset bevel gear toothing and surrounding a respective one of the roller axes, the drive gears engaging with the sun gear so that the rollers are driven by the sun gear through the drive gears.

    摘要: An arrangement for inclined rolling of tube-and bar-shaped rolling articles has two or more driven rollers rotatable about a longitudinal axis of a rolling article and supported in or on a rotor which surrounds the rolling article. The rotor is arranged in a stationary housing which is closed from all sides to provide a compact and efficient arrangement allowing an especially high rotary speed. Moreover, the arrangement with the inclined rollers rotatable about the longitudinal axis of the rolling product allow a fast exchange of the whole arrangement by a pre-assembled second arrangement so that stoppage of the whole arrangement during a roller exchange or a change in the roller adjustment is substantially reduced.

    摘要: In the manufacture of hollow metal ingots, particularly for producing seamless tubes, the liquid melt is poured rapidly into an upright or slightly inclined chill mould, the chill mould is closed and is tilted into a substantially horizontal position in which it is slowly rotated about its longitudinal axis. The hole is produced in the hollow ingots by pouring into the chill mould a quantity of melt which corresponds to the total volume of the chill mould plus the shrinkage volume and less the volume of the desired hole. The method is particularly advantageous when manufacturing hollow ingots of great length, although the method can also be used when manufacturing short hollow ingots. It is particularly advantageous to blow in an accurately dimensioned quantity of inert gas, corresponding to the hole in the hollow ingot, during and after the actual pouring operation.
