Abstract
1,251,000. Rolling. J-P CALMES. 23 March, 1970 [27 March, 1969], No. 13921/70. Heading B3M. A roll stand for a multi-stand tube rolling mill comprises at least two rolls driven by at least one asynchronous motor, the motor being fed through a frequency converter, preferably static, which is adjustable to vary the speed of the motor. The roll stand of the preferred embodiment, Fig. 1, has three rolls 4 in a frame 2 the shafts of which are driven through gears 9 and magnetic clutches 6 by motors 10. Successive stands in the mill have their rolls offset by 60 degrees with respect to the preceding stand. The upper motors 10 as shown are mounted on a frame 8 pivotable about a shaft 11 by means of hydraulic cylinders 12 so that roll frames 2 can be lifted out of the rolling mill. The upper frame 8 is locked by an hydraulically operated locking device 13. The motors of a roll stand are preferably linked to a common frequency converter or to frequency converters whose output is synchronized.
