A block-type roll stand arrangement for single strand rolling including roll stand housings mounted on a support structure. The roll stand housings are all of the same construction and each receives a pair of roll support shafts and the drive gear units therefor. The roll stand housings are arranged one behind the other with the roll support shafts being alternatingly inclined at an angle relative to the rolling line. Stiffening ribs are arranged between the plate support members. The stiffening ribs are connected to the side surfaces of the plate support members and to the base plate. The stiffening ribs may be composed of angle sections with a symmetrical angle cross-section, wherein the parallel outer edges of the angle sections rest on the base plate and whose angle-shaped front and rear side edges rest against the side surfaces of the plate support members.

Roll stand arrangement for single strand rolling

A wire roll stand with roll rings mounted in a cantilevered manner onto roll shafts, wherein the roll rings can be axially clamped through spacer rings against an end of the respective roll shaft. The roll shafts are adjustable by eccentric bushings mounted in a housing and the eccentric bushings as well as the roll shafts are sealed relative to walls of the housings. The housing wall through which the roll shafts extend is equipped with openings which take into consideration the adjusting range of the roll shafts, wherein the openings are fixedly lined with sealing rings having a U-shaped profile. The spacer rings have a U-shaped profile and are composed of at least two parts with separating surfaces thereof extending within the profile yokes, wherein the sides of the spacer rings rest on the sides of the sealing rings within the adjusting range. The housing wall through which the roll shafts extend has blind-end bores for supplying pressurized water, wherein the blind-end bores are provided with outlet openings directed toward the sides of the sealing rings facing the roll.

Wire roll stand

A rolling mill drive with spindles arranged axially slidably between pinions and work rolls. A joint of each spindle is releasably connected to the neck of at least one roll, particularly the work roll. At least the spindle joint connected to the work roll includes a coupling and uncoupling device, preferably an annular bayonet-type coupling device.
