The invention relates to a method of precise positioning of a number of cooperating cylinder or roller elements () of a roller or casing installation () relative to each other. In order to be able to bring off a rapid and precise alignment of the cylinder or roller elements, according to the invention, it is provided that with a measuring apparatus (), a distance (a, a, a, a) between at least three reference points (), which are provided directly or indirectly on each of the cylinder roller elements (), and the measuring apparatus is measured, and that dependent on measurement results, adjusting elements () on each cylinder or roller element () are so operated that the distances (a, a, a, a) between the reference points () and the measuring apparatus conform to predetermined values to a best possible extent, wherein the measurement points () of each cylinder or roller element () are arranged, directly or indirectly on a carrier element () of the cylinder or roller element (). The invention further relates to a roller or casting installation, in particular for carrying out the method.

The invention relates to a mold divider for fitting in a conventional slab mold () having laterally adjustable narrow-side parts for selective casting of several strands with changeable strand widths. The mold divider consists of a housing () fixedly securable relative to the mold (), between the broad-side plates () and having bilaterally adjustable, in a broad-side direction of the mold (), adjusting organs (), with supporting plates () provided at their ends and with the narrow-side heat-exchanger plates () arranged thereon.

Adjustable mold divider for fitting in a conventional ingot mold

A method for producing steel slabs, whereby the strand leaves an ingot mold with melt enclosed by a strand shell and, in a strand guide located downstream, the opening width of guide rolls mounted in segments with upper and lower frames can be set in a continuous manner with successive steps by adjusting elements that join said guide rolls. An oscillation around a center line of the opening width serves to modify the opening width in order to render the dynamic influences on the guide rolls negligibly small. The amplitude of the opening width oscillation is set to ta quantity, which des not provoke any plastic deformation of the strand shell. The actual opening width of the guide rolls is detected and the actuating force of the adjusting elements as well as the amplitude of the actuating force are determined at the same time. In the case of an increasing amplitude of the actuating force, the opening width is set to a predeterminable measure and/or guided in a pressure controlled manner via at least one adjusting element. A force/path diagram of the opening width setting is then determined form a multitude of force/path measurements along the strand. Said diagram is composed, in a chain-like manner, of a multitude of small force path curves, which are each provided in the form of a hysteresis and which can be individually determined using an oscillation with a comparatively small amplitude.

Method for producing steel slabs

A method and a device for adjusting one or more roll segments ( ) in a continuous casting installation for metals, especially for steel materials, the rolls ( ) of which adjusted in the segment upper frame ( ) and the segment lower frame ( ) on frame cross members ( ) by pairs ( ) of hydraulic piston-cylinder units in a position-and/or pressure-controlled manner, wherein an operation for guiding and/or pressing the casting strands ( ) is switched from a position-controlled to a pressure-controlled operation when pressure within the respective pair ( ) of piston-cylinder units reaches a predetermined maximum value, whereby an improved reaction is effected by operating the piston-cylinder unit of every roll segment ( ) in the case of overload, in subsequent steps at a reduced pressure or in a pressureless switching mode until the switching mode is reached in which the segment upper frame ( ) can be opened to some extent.

Method and device for producing slabs of steel

In a method for casting prefabricated products in a continuous casting device, having a casting mold and a strand guide downstream of the casting mold, wherein the strand guide has rolls positioned opposite one another in pairs for supporting and guiding the solidifying cast strand, wherein some rolls are drive rolls and others are idle rolls, wherein drives are provided for the drive rolls, and wherein the drive rolls are adjustable against the cast strand in order to transmit guiding forces and strand conveying forces onto the cast strand in interaction with the idle rolls, the drive rolls and the drives are controlled to a preset rotational speed such that the drive rolls have circumferential speeds identical to one another within the limits of a preset casting speed. The motor torques of the drives are maintained at a level as equal as possible below a permissible torque limit value relative to a loadability of the strand shell.

An adjustable plate mold includes two broad-side walls and first and second narrow-side walls clampable between the two broad-side walls to define a size if a slab formable by the plate mold. A frame work includes cassette holders corresponding to the narrow-side walls. Actuating elements are inserted in the cassette holders and connected to the first and second narrow-side walls for moving the first and second side walls to change the size of the slab formable by the plate mold. The framework also includes a holding part for maintaining the narrow-side walls at a constant horizontal level relative to the cassette holders.

In a method for casting prefabricated products in a continuous casting device, having a casting mold and a strand guide downstream of the casting mold, wherein the strand guide has rolls positioned opposite one another in pairs for supporting and guiding the solidifying cast strand. The motor torques of the drives are maintained at a level as equal as possible below a permissible torque limit value relative to a loadability of the strand shell. For a single drive and corresponding drive roll the permissible torque limit value is measured by continuously increasing the drive torque starting at zero and monitoring the rotational speed of the drive roll, while the remaining drive rolls are controlled to a preset nominal casting speed. For a superproportional increase of the rotational speed, the torque limit value is determined and the process is stopped.

A strand guide, in particular for a continuous slab-casting plant for steel, with supporting segments in which frames are arranged that have rows of guide rollers and driving rollers arranged opposite one another, wherein the frames are held opposite one another by tie rods. Two guide members are provided at one end of a frame at equal distance from the center axis. The guide members are fastened to at least one fixed point via holding elements and are arranged conically at an opening angle relative to one another.

Device for the continuous casting of steel

A mold arrangement for the production of endless castings of metal, particularly slabs of steel, having copper plates for the wide sides of the mold which rest on coolable support plates, and narrow sides which can be clamped between the wide sides. Additionally, an oscillating device is connected with the support plates. The support plates are trough-shaped in the region of the mold wide sides. Channels are provided in the wall of the support plates for the passage of a cooling fluid. Electromagnetic structural parts arranged on mounting frames can be freely introduced into the trough free space which faces away from the wide sides.
