Definitions

the invention relates to a strand guide for a continuous sheet caster, in particular for a steel slab caster, with at least one arcuate, horizontally displaceable support and guide frame.
the invention aims to avoid these disadvantages and difficulties and has as its object to provide a strand guide of the type described above, in which the displaceable support and guide frame can be easily removed and installed, but with good access to the system , the space on the casting platform is not limited and the smallest possible size of the hall is sufficient.
the supporting and guiding frame is mounted on at least one intermediate frame which is adjustable in the arch plane and the intermediate frame is supported on at least one support frame which is adjustable transversely to the arch plane.
both the intermediate and the support frame are designed as a chassis, with the intermediate frame on the chassis rails arranged horizontally and in the arch plane can be moved, and expediently provided for displacing the support and guide frame in the arch plane as well as at right angles to it, fixedly arranged pressure medium cylinders which can be coupled to the support and guide frame or to the support frame.
pressure medium cylinders has, for example, the advantage over traction motors arranged on the chassis that no electrical supply lines have to be provided, which would be undesirable in the water-loaded cooling chamber.
Pressure fluid cylinders also have advantages over endless chain or cable drives; they are better and easier to protect against pollution from scale and rust.
a pressure medium cylinder with a smaller stroke than the total travel path of the support frame is provided for moving the support frame, the support frame being able to be coupled with an extension of the piston rod of the pressure medium cylinder at different distances from the pressure medium cylinder, since this results in a relatively small amount short pressure medium cylinder is enough.
FIG. 1 shows a schematic side view of a continuous casting installation
FIG. 1a shows a detail on a larger scale
FIG. 2 shows an analogous representation with the support and guide frame lowered
FIG. 3 shows a section along the line III-III of Fig. 2 show on an enlarged scale.
a support frame is moved to its outermost end position in a representation analogous to Fig. 3.
the arcuate support and guide frame 3 has on its outside in each case paired cambered support surfaces 7, 8 at different heights, with which it is loosened by means of lifting elements, such as pressure medium cylinders, on a counter support surface 11 after loosening its attachments 9 on the stationary support frame 10 of an intermediate frame 12 can be placed, each support surface 7, 8 being assigned its own intermediate frame 12, which has a counter support surface 11.
Each intermediate frame 12 is designed as a chassis and can be moved by means of wheels 13 on rails 14 arranged horizontally in the plane of the arc.
These rails 14 are mounted on support frames 15, 16, each support frame also being designed as a chassis which can be moved by means of wheels 17 on rails 18 arranged horizontally and at right angles to the plane of the curve.
a respective support frame 15 or 16 is assigned to a pair of supporting surfaces 7 or 8 arranged at the same height.
the rails 18 are mounted on the stationary support structure 10.
a pressure medium cylinder 19 which is provided below the upper support frame 16 and is fixedly mounted on the support frame 10 and can be coupled to the support and guide frame 3, is used. It is shown in the retracted, uncoupled position in FIG. 1, in contrast, in FIG. 2 in the engaged position.
This tube 22 extends into a sleeve 23 of the support frame 15 and 16 and is connectable to this sleeve 23 by means of a bolt 24 which can be removed and inserted by hand.
the stroke 25 of the pressure medium cylinder 20 is only a fraction of the total travel path 26.
the tube 22 has several bores 27, 27 ', 27 ", 27'" ... distributed over its length, into which the bolt 24 can be inserted , whereby the sleeve 23 can be attached to the pipe 22 at different distances from the pressure medium cylinder 20.
the intermediate frames 12 are each laterally protected by plates 28 mounted on the respective frame 15, 16 and can be fixed by means of bolts 29 on the plates 28 and thus in their position relative to the frame 15, 16.
Each bolt 29 passes through bores 30 of the intermediate frames 12 and corresponding bores 31 of the plates 28.
a ratchet-like device could also be used, which allows the sleeve to move relative to the tube in only one direction.
the device can be switched so that the relative movement can optionally also be carried out in the opposite direction.
the invention can also be implemented for shorter support and guide frames arranged one behind the other, each support and guide frame being movable by means of at least one intermediate and support frame.
