Definitions
- the invention relates to a device for accommodating a continuous casting mold on a lifting table for casting liquid metals, in particular liquid steel materials, which is set in vibration by means of several hydraulic oscillation drives when the partially rigid casting strand is pulled out, the frequency and the amplitude depending on the respective strand cross section, such as slab, thin strand, bloom, pre-profile or billet strand cross-section as well as the respective casting material and / or the casting parameters (casting speed) and guide elements for an optimal oscillation curve connect the lifting table with a local linkage.
- liquid metals in particular liquid steel materials
- the device described at the outset is known from EP 1 029 616 A1.
- This device is used in particular for casting thin strands of steel. It comprises an oscillating continuous casting mold placed on two lifting tables arranged on both sides of the casting strand.
- the oscillation drive is designed in the form of servo cylinders by means of piston-cylinder units arranged on a stationary base frame. Each side of the lift table is articulated to the head of the piston-cylinder unit.
- the base of the piston-cylinder unit is articulated to the base frame.
- Each lift table side is guided on the base frame via articulated handlebars.
- the axes of the joints and the joints on the heads of the piston-cylinder units and the axes of the joints on the links are aligned parallel to one another.
- the periodic oscillation movements of the continuous casting mold cause friction between the continuous casting mold and the casting strand or its Strand shell that can be reduced by melting lubricant.
- an oscillating excitation of the entire casting strand and / or the bath level in the continuous casting mold takes place, particularly in the case of sinusoidal vibrations, which is undesirable.
- Such oscillations can be damped by oscillation curves that deviate from the shape of the sinusoid.
- Such deviating curve shapes also have an advantageous effect on the oscillation marks, their depth and shape in the strand surface and improve the surface quality.
- the prerequisite for the generation and transmission of suitable oscillation curves is the structure and the system of the device itself which receives the continuous casting mold.
- the oscillation generation (for example described in EP 0 121 622 B1) is operated according to a preselected oscillation amplitude signal generated by a function generator at a frequency which is higher than the natural frequency of the device.
- the invention has for its object to provide a combination of lifting table and continuous casting mold to which functional vibrations can be transferred with high accuracy.
- the lifting table is made in the form of a frame and in one piece and forms an interior space which is free for the passage of the casting strand and is dimensioned accordingly, and that the oscillation drives are arranged in the corners within the frame surface and are distributed in pairs on an arcuate or together can be controlled fully synchronized for a vertical, straight pull-out movement.
- Practical experience has shown that a full Synchronization of two or more hydraulic drives can be achieved. A contribution to this is made, for example, by an overall lower overall height of the device. It is also advantageous to retrofit existing devices to the new design.
- One embodiment provides that the continuous casting mold with its cooling units is placed directly on the frame-shaped lifting table.
- the frame-shaped lifting table offers sufficient contact areas for this.
- a further development consists in that the frame-shaped lifting table is provided with cooling channels which are connected to a cooling medium network.
- the advantage is a narrow interior that runs around the casting strand cross-section at a small distance. With a low cooling capacity, the distance to the hot cast strand can also be kept larger. In addition, a certain cooling capacity is provided by the spray cooling, which is already present.
- the fixed articulation of the guide elements consists of leaf springs mounted in an articulated manner on the lifting table and on a fixed base frame in package form.
- the device for accommodating a continuous casting mold 1 with a water box 1a and narrow side 1b has, as is known from the prior art shown, two individual lifting tables 2 and 2 for casting liquid metals, in particular liquid steel materials.
- the lifting tables 2, 2 are set in vibration there by means of several hydraulic oscillation drives 3 when the partially solidified casting strand 4 is pulled out.
- the frequency and the Amplitudes are matched to the respective strand cross-section 5, such as slab, thin-strand, bloom, pre-profile or billet strand cross-section 5, as well as to the respective casting material.
- guide elements 6 are provided which connect the lifting tables 2, 2 to a fixed linkage 7 for an optimal oscillation curve.
- the invention changes the known system in such a way that the lifting table 8 is designed in the form of a frame and in one piece.
- the lifting table 8 therefore has an interior space 8a which is kept free for the passage of the casting strand 4 and is dimensioned accordingly.
- the oscillation drives 3 as piston-cylinder units 3a and these as servo-cylinder units 3b are arranged in the corners 8b within the frame surface 8c and are distributed in pairs on a side in an arcuate manner or can be controlled together for a vertical, straight pull-out movement 9.
- the synchronization of two or more hydraulic drives has been practically proven with this design and is therefore possible. There were deviations of a few hundredths of a millimeter between the two sides of the lift table.
- the lifting table 8 thus created directly receives the continuous casting mold 1 with all its cooling units 10 and is therefore simply placed on the frame-shaped lifting table 8.
- Protection against the radiant heat of the casting strand 4 can be provided in such a way that the frame-shaped lifting table 8 is provided with cooling channels which are connected to a cooling medium network.
