The arrangement includes one or more steel strip casting plants which are followed by a temperature equalizing furnace, a transverse conveying unit for steel strip sections and a finishing mill. The finishing mill is arranged laterally offset and in the opposite direction of the discharge direction of the steel strip casting plant. Another temperature equalizing furnace is arranged which conveys in the opposite direction of the first temperature equalizing furnace and toward the finishing mill. The temperature equalizing furnaces arranged next to each other are connected to each other by a transverse conveying unit arranged at the front end of the temperature equalizing furnaces.

Arrangement for manufacturing steel strips

The bending and balancing mechanism for axially shiftable rolls of a roll stand, especially the working rolls of a four-high roll stand, comprises a guiding block rigidly mounted in a stand window of each roll stand and roll supporting members supported horizontally slidable adjacent both ends of the rolls on an upper and/or lower lifting housing guided vertically on the guiding block. The roll bending forces are transmittable from bending cylinders to the roll supporting members and at least one bending cylinder, advantageously hydraulic cylinder, engages on the upper and lower lifting housing, this bending cylinder being supported on a stationary guiding block. Because of this latter structure the bending and balancing forces are better transmitted to the working or other rolls.

A roll stand has a stationary frame having a drive side and a service side, upper and lower working rolls having axially opposite ends at the sides, respective pairs of upper and lower journal blocks coupled with the ends of the rolls at the sides and a drive connected to the working-roll ends at the drive side for oppositely rotating the working rolls. Respective upper and lower pusher bodies are provided adjacent the journal blocks in the frame and respective upper and lower guides in the frame support the bodies for displacement of same only axially in the frame. Respective pairs of formations at least one of which is vertically elongated couple each of the bodies to the respective block for joint axial displacement while permitting relative vertical nonaxial displacement between the bodies and the respective blocks. One of the pusher bodies can be pushed axially with the respective journal block and roll in the frame and racks are formed on the pusher bodies in mesh with a service-side gear that is supported on the frame for rotation on the service side about a stationary axis perpendicular to the racks and nonmovable on the frame so that axial displacement of one of rolls with the respective rack rotates the gear and axially oppositely displaces the other working roll regardless of the relative vertical positions of the rolls.

A method and apparatus for height or level-positioning of rolls in rolling mill frames, for adapting the upper edge of the lower working roll to the rolling plane, and for changing the rolls, expecially in four-high mills equipped with a roll changing cart which can travel in the longitudinal direction of the rolls, and equipped with interchangeable shim plates of various individual thicknesses for supporting the holding elements of the support rolls. The apparatus affords an infinitely variable and continous adaptation to the wear of the rolls. The apparatus is operated such that the level or position of the individual shim plates is carried out infinitely variable by way of a short vertical stroke. The mill preferably includes a system of movable wedges which includes two upper wedges and two lower wedges.

Method and apparatus for level control of rolling mill rolls

A rolling stand including a pair of working rolls and associated backing rolls, the working rolls defining a nip through which a strip can be advanced in a succession of passes forming a single run, so that with each pass the thickness and widths of the strip are reduced. The working rolls have end regions projecting laterally beyond the longitudinal edges of the strip, and machining devices are provided on the frame of the stand to reduce the diameters of the projecting end regions of the working rolls after each pass during a single run so that the working rolls ony contact the respective backing rolls along a distance equal generally to the strip width. Each machining devices includes a support carrying a material-removing tool engageable with the juxtaposed end region of a respective run of the working rolls, each support being pivotable about the respective backing-roll axis and linearly displaceable along the respective working-roll end region to enable the respective tool to be moved both perpendicularly and parallel to the axis of the working roll. Respective stop elements pivotable about pivot axes parallel to the working-roll axes carry eccentric stops which are engageable with the tool supports to define the radially innermost end positions of the supports.

In a method of rolling wide strip starting material, an ingot slab is rolled to the desired wide strip width by having its shorter sides edge-rolled. In order to save time, energy, material and investment capital, the ingot slab has a cross-section tapered towards the shorter sides in a wedge-shaped or curved manner at both edges, and is edge-rolled approximately to the wide strip width desired while filling out the rectangular shape.

Method of rolling wide strip starting material

A rolling stand includes a frame and a pair of working rolls mounted on the frame centered on and rotatable about respective parallel axes and defining a nip so that a strip can pass in each of a succession of passes forming a single run through the nip so that with each pass the thickness and width of the strip are reduced. The ends of the working rolls project laterally beyond the longitudinal edges of the strip. Respective backing rolls mounted on the frame extending generally the full length of the working rolls are braced toward the nip against the working rolls to urge same against the strip. Tools displaceably mounted on the frame reduce the diameters of the projecting ends of the working rolls several times after respective passes during a single run so that the working rolls only contact the respective backing rolls along a diatance equal generally to the workpiece width. The tools are lathe-type tool bits and respective holders juxtaposed with the end regions and rotatable about respective axes parallel to the respective working-roll axis each carry a plurality of radially projecting and radially and angularly spaced such tools. The holders can be angularly stepped to bring successive tools into engagement with the respective end regions. These holders of each roll are coaxial and axially oppositely displaceable.

Strip-rolling method and apparatus

Coils of metal strip are cooled by being placed on porous supports with the coil axes vertical. Water is introduced into the coil interiors and most of the water overflows the coil tops and thereby cools the coil tops and peripheries. A small proportion of the water flows out through the porous supports and thereby cools the bottom ends of the coils. The water is preferably introduced from below. Apparatus for performing cooling is disclosed.
