Definitions
- the invention relates to a method and a device for positioning one or more roller segments in a continuous casting installation for metals, in particular for steel materials, the roles of which in the upper segment of the segment and in the lower frame of the segment are regulated in position and / or pressure by pairs of hydraulic piston-cylinder units on frame cross beams be switched, whereby a switch is made from a position-controlled to a pressure-controlled operation for guiding and / or pressing the casting strand when the pressure within the respective pair of piston-cylinder units reaches a predetermined maximum value.
- the mouth width which corresponds to the thickness of the casting strand, is continuously adjusted during casting by hydraulically interconnecting two adjacent servo-piston-cylinder units in a strand guide segment with four piston-cylinder units linked to the strand and the other servo piston-cylinder units are set independently (DE 196 27 336 C1).
- the strand shape of the transition pieces and a ski shape create a particularly high load.
- the resulting casting strand geometry is transported through the entire casting plant and passes through each roller segment, whereby locally different load conditions arise.
- the strand guidance and suppression of the strand bulge by the ferrostatic pressure must always be guaranteed. These conditions require special measures.
- the object of the invention is to counter an impending overload by a more effective reaction of the respective roller segment, i.e. to provide further protective measures.
- the object is achieved according to the invention in that, in the event of an overload, the piston-cylinder units of each roller segment are moved in successive stages with a reduced pressure or in an unpressurized switching state up to the switching state for limited opening of the upper segment frame.
- a more effective reaction of the roller segment with increasing load can be targeted to the local load forces, that is to say, avoiding the coming one Overload take place regulated.
- the segment upper frame with rollers and bearings actively avoids the build-up of the overload when switching.
- the device for setting up one or more roller segments in a continuous casting plant for metals, in particular for steel materials is based on the generic type of rollers in the segment upper frame and segment subframe, which can be adjusted in a sequence by means of pairs of hydraulic piston-cylinder units on frame traverses in a position and / or pressure-regulating manner are switched from a position to a pressure-controlled operation for guiding and / or pressing the casting strand when the pressure within the respective pair of piston-cylinder units reaches a predetermined maximum value.
- the object is achieved with regard to the device according to the invention in that in the path of the upper segment of the segment an adjustable loading border is arranged. As a result, the segment upper frame does not have to cover the entire possible driveway.
- the drive-up limitation is arranged between the upper segment frame and the lower segment frame.
- an advantageous arrangement consists in the fact that the approach limit is assigned to each piston-cylinder unit in the immediate vicinity.
- each piston-cylinder unit is given such an opening limitation.
- the drive-up limitation consists of an angle lever which can be swiveled in and out, the swivel axis of which is mounted on the segment subframe with the first lever arm and the second lever arm is in a swiveled-in position under the segment upper frame.
- the opening limits are only swiveled in for the casting operation. In the maintenance shifts, the access limits can be swung out, which means that the full opening and full opening of the upper segment frame are available for maintenance work.
- the drive-on path is determined according to other features in that the drive-on limitation on the upper segment frame forms an abutment with a predetermined gap distance.
- the gap distance can be formed in such a way that supplements for an incrementally variable gap distance can be stacked on the abutment of the segment upper frame, and the number and thickness can be selected individually on each segment upper frame or on each piston-cylinder unit.
- An improvement of the invention is given by the fact that the drive-up limiter is simultaneously designed as an overload protection device in the form of the angle lever with a predetermined breaking point
- roller segment 130 is provided. In this way, the roller segment can be additionally secured against extreme upper loads (so-called special casting cases).
- FIG. 1A shows a side view of a roller segment in the clamped position
- FIG. 1B shows details "A" according to FIG. 1A in an enlarged view
- FIG. 2 A is a front view of a roller segment in the clamping position
- FIG. 2 B shows the front view of the roller segment with the maximum opening
- FIG. 3 shows a side view of a roller segment without restriction
- FIG. 4 A shows a front view of the roller segment in clamping position, without restriction
- FIG. 4 B shows the front view of the roller segment outside of the
- FIG. 6 shows a detail of the mounting of an angle lever
- Fig. 7 is the side view belonging to Fig. 6 of the storage of
- the device in a continuous casting installation for metals, in particular for steel materials is used to place one or more roller segments 1, each of which consists of, for. B. six rollers 1a (pairs of rollers) on a roller segment 1, which are rotatable in a segment upper frame 2 and a segment lower frame 3 and partially rotating.
- segment upper frame 2 and the segment subframe 3 can be adjusted by means of pairs 4 of piston-cylinder units on frame traverses 5 in a position and / or pressure-controllable manner in a sequence control which results from the casting direction 6a of the casting strand 6 (a slab strand is shown).
- the operation is switched from a ⁇ o position to a pressure-controlled setting as soon as the pressure within the respective pair 4 of piston-cylinder units reaches a predetermined maximum value.
- the casting strand 6 can be a slab strand or have a bloom block cross-section, such as. B. a dog-bone profile.
- An adjustable drive-up limiter 7 is arranged in the adjustment path of the upper segment frame 2 (FIGS. 1B and 1C).
- the opening limit is generally between the upper segment frame 2 and the lower segment frame 3 ..
- the opening limit 7 is designed as an angle lever 7a.
- the angle lever 7a is assigned to each piston-cylinder unit in the immediate vicinity (FIGS. 1A, 2 A, 2 B and FIGS. 5, 6 and 7).
- the angle lever 7a is fastened to the segment subframe 3 by means of a pivot axis 8.
- the angle lever 7a has a first 185 lever arm 9a and a second lever arm 9b.
- the angled lever 7a In the pivoted-in position 10 (FIG. 1B), the angled lever 7a is opposite an abutment 11, which is attached to the upper segment frame 2. Supplements 13 are placed on the abutment 11 so that there is a maximum gap distance 12 from the pivoted-in drive-in limiter 7.
- the gap distance 12 is not present in the clamping position of the upper segment frame 2 and its maximum size is visible according to FIG. 213.
- the roller bearing 15 is in slide or roller bearing design under the correspondingly high load.
- the limit stop 7 is also designed as an overload protection 14.
- the angle lever 7a is provided with a predetermined breaking point 16.
- the casting process would be severely impaired because the starting head of a starting strand would require a transition piece from cold strand to warm strand, a composite piece when composite casting different batches, and the strand end piece would require a “plasticizer” of the clamping force, the adjusting force being regulated depending on the location must become, but what can only happen poorly.
- the drive-up limiter 7 is shown with the angle lever 7a in the pivoted-in position 10 and with dashed lines in the pivoted-out position (FIG. 6B).
- the angle lever 7a is mounted about the axis 8 in the segment subframe 3 and an abutment 11 is formed on the 225 segment upper frame 2, on which the inserts 13 are stacked.
- the maximum gap spacing 12, in which the segment upper frame 2 can shift, is visible over the inserts 13. This creates a very short movement distance of the upper segment frame 2.
