Definitions

the invention relates to a strand guide segment for Slab caster with one between guide rollers fixed frame and a loose frame distance-adjustable guide width for the casting strand, where the frames for overcoming the ferrostatic pressure and for Setting the desired format width of the strand with Interacting means interact.
Continuous casting plants in particular for casting steel slabs, use rollers to guide the strand, one more not limit solidified strand in its thickness and one Bulging of the strand shell due to the ferrostatic Prevent internal pressure.
DE 196 27 336 C1 describes one method and one Device for guiding a strand in a Continuous caster with a "soft reduction line" known, with the hydraulic servo units the mouth width of the Continuously adjust opposite strand guide rollers.
the well-known strand guide which is four per segment Servo piston cylinder units for stepless adjustment of the Mouth width of the opposite strand guide rollers has, is characterized in that hydraulic lines Ring surfaces and piston surfaces of two neighboring ones Servo piston cylinder units with a common servo valve connect, and that position transmitter's with a common Servo valve controlled servo piston cylinder units are technically interlinkable.
the clamping cylinders are usually on the side of the segment arranged the roles and are therefore inclusive of hydraulic lines and servo valves Servo piston cylinder units in the area of Radiation exposure of the casting strand. You need to consequently at such a distance - middle segment - Hydraulic cylinder - be arranged that the Radiation exposure remains limited.
the one for this required frame width of the segment leads because of The load on the frame is comparatively heavy construction, which the cost of manufacturing and Assembly and the scaffolding costs significantly burdened.
the invention lies Task, a strand guide for Slab casting plants mentioned in the preamble of claim 1 Art significantly compared to conventional designs Simplify to do this with impression cylinders through their Storage in the area of the upper frame outside the cooling chamber are and with a lighter frame construction and simplified water cooling system and piping for the roller cooling contributes a substantial saving in costs Manufacture and assembly of the strand guide elements achieve.
the strand guide segment shown in Figure 1 for Slab caster has one between guide rollers (1) loose side frame (3) and guide rollers (1 ') one fixed frame (2) an adjustable distance Guide width (F) for the casting strand (10), the Frame (2, 3) to overcome the ferrostatic pressure and for setting the desired format width of the strand (10) interact with actuators.
adjustable pressure cylinders (4, 4 '; 5, 5') are provided and outside the radiation range at the top of the Segment arranged, the one determining the segment width Distance (A) segment center cylinder by the amount of the to the Top of the segment shifted cylinder (4, 5) on both sides is narrowed.
FIG. 1 shows and 2 the connection of one printing cylinder (4) or (5) on the side frame (11) with the help of a universal joint (15).
Fig. 1 shows the connection of the guide frame (2) over the subframe (8) with the Side frame (11) into a compact structural unit.
Fig. 1 shows the connection of the guide frame (2) over the subframe (8) with the Side frame (11) into a compact structural unit.
the Pipe guide for cooling the rollers (1, 1 ') essential simplified. Between the guide rollers (1) in Fig. 2 is the of this led casting strand (10) with dash-dotted Lines indicated.
Figure 3 shows a standard printing cylinder (4, 5), the Flange (14) in a spherical cap Guide (13) is added. But also a rigid one Attachment according to Figure 3a is when articulated Cardan double joint on the loose frame (3) expedient. With it and with the gimbal connection of the Cardan joint (15) according to FIGS. 1 and 2 and in particular Fig. 3a results in an optimal adhesion between one Cylinder (4, 4 '; 5, 5') and one of the side frames (11) without lateral constraint.
Figure 4 shows the advantageous use of Radiation protection plates (7) on trusses (6) of the Strand guide segment.
the illustration demonstrates in convincingly after with the radiation protection plates (7) simplification achievable compared to the invention water-cooled segment cross members.
the invention is comparatively uncomplicated Construction very well suited to the task at the beginning realize and solve them in an optimal way.
