A device for changing a roll disk arranged in a free-floating fashion on a roll shaft and braced against a shoulder of the roll shaft, the device including a roll shaft piece connectable to an end face of the roll shaft and having radially projecting claws. An installation-and-removal unit is placeable on and coaxially turnable to the roll shaft. The unit has radially extending first, second and third claws that form perimeter segments. The first claws correspond to and engage with the claws of the roll shaft piece. A taper bushing is slidably provided between the roll disk and the roll shaft to hold the roll disk on the roll shaft, and has radially extending claws. The second claws correspond to and engage with the taper bushing claws, and are also moveable axially to the roll shaft. A ring is coaxially mounted on a side of the roll disk facing the unit, and has radially extending claws that correspond to and engage behind the third claws. All the claws have a perimeter extension whereby the corresponding claws lie perimetrically next to one another in a plane seen in the axial direction when the unit is placed on the roll shaft. The unit is turnable between a first position in which the claws of the roll shaft piece and the taper bushing respectively engage with the first and second claws, and a second position in which only the claws of the ring engage with the third claws.

Quick-changing device for roll disks

Oxygen-free copper, particularly wire, is manufactured in a casting and rolling plant composed of melting plant, continuous casting mold and a subsequently arranged continuous rolling mill. The method includes bending a billet leaving the casting plant along a straight line into the horizontal, after the billet has been reduced in at least one shaping pass. The arrangement for carrying out the method includes at least one shaping stand arranged following the continuous casting mold, wherein the rolling axis of the shaping stand coincides with the longitudinal center axis of the continuous casting mold. The region between melting furnace and continuous casting mold and the region between continuous casting mold and the shaping stand are arranged under gas shrouding.

Method of manufacturing rolled material from oxygen-free copper

A metal casting device employs a number of pairs of mold members which can be opened or closed with respect to each other. The mold chamber pairs cooperate, in their closed state, to form a linear mold chamber. In order to compensate for shrinkage as the metal cools, the mold member pairs are movably supported by an endless chain, with the pairs of cooperating mold members being provided with contact faces having the same angle of inclination. Each mold member pair is also equipped with supporting rollers with which the associated mold chamber section can be closed or opened, as required.
