Definitions
- the invention relates to a device for the continuous casting of metals, in particular steel, by means of a continuous casting mold which is mounted in an oscillating frame which can be driven in an oscillating manner in the casting direction, the stroke of the oscillating movement and / or the frequency being adjustable and the oscillating frame being arranged symmetrically on both sides of the casting line Spring packs for guidance and weight compensation is stored.
- the object of the invention is to improve the casting into more complicated casting cross sections compared to simply rectangular slab cross sections.
- the object is achieved on the basis of the device for continuous casting of metals, in particular steel, according to the invention, by application to a continuous casting mold with a profiled casting cross section mounted in the oscillating frame, the leaf spring-mounted oscillating frame with continuous casting mold being operable in the resonance oscillation process.
- the use of leaf springs guarantees a backlash-free and wear-free deflection with an improvement in the guiding accuracy by a multiple of previous oscillation devices and thus a significant reduction in the friction of the strands.
- a sinusoidal or deviating oscillation with high frequencies and small lifting heights contributes to this.
- This so-called resonance oscillation is also favored by the reduced mass of the oscillating frame. It is now possible to produce a high surface quality even on profiled casting strands, which is associated with an improvement in the structure close to the edge. Furthermore, a reduction in the sensitivity to cracks can be achieved.
- the continuous casting mold with a profiled casting cross section has a dog-bone-shaped casting cross section.
- the strand surface can in principle be improved in that the oscillation movement can be changed by means of the drive in the oscillation stroke and / or in the frequency and / or in the oscillation curve.
- the decrease in For this purpose, friction can be calculated using calculation models and the values obtained can be entered into the control of the respective drive.
- the frictional force can be influenced via the lifting height of the oscillating movement of the oscillating frame.
- the continuous casting mold operated in the resonance process can have a low frictional force value in that the stroke height of the oscillating movement of the oscillating frame can be adjusted to approximately 0.3-6 mm.
- the storage of the continuous casting mold for the resonance oscillation process is designed according to an improvement in such a way that leaf spring assemblies running in pairs on both sides are spring-mounted in a base frame at an acute angle to one another, and that the oscillating frame carrying the continuous casting mold is centered on the ends between the ends Leaf spring assemblies and the swing frame is attached and connected to these bearing blocks.
- This storage achieves the desired precise guidance with the lowest possible mass of the components.
- the upper pair of leaf springs is fastened in a horizontally extending manner in the horizontally or inclinedly arranged base frame.
- the surface of the solidifying casting strand can be monitored such that a hydraulic drive is provided for the oscillating frame, to which a measuring device for determining the pressures in the drive cylinder is connected, on the basis of which the frictional force between the casting strand and the continuous casting mold can be calculated ,
- Continuous casting mold in view and Fig. 2 shows a cross section through a resonance continuous casting mold.
- a device for the continuous casting of metals, in particular steel, by means of a continuous casting mold 1 which is mounted in an oscillating frame 3 which can be driven to oscillate in the casting direction 2, the stroke of the oscillating movement and / or the frequency being adjustable and the oscillating frame 3 by means of leaf spring assemblies 4a, 4b; 5a, 5b is mounted for guidance and weight compensation.
- the continuous casting mold 1 has a profiled casting cross section 1 a, the leaf spring-mounted oscillating frame 3 being operated together with the continuous casting mold 1 using the resonance oscillation method.
- a dog-bone shape is shown as a striking example of a profiled casting cross-section 1a, with which the starting material for double-T profile rails is cast.
- a homogeneous surface without major defects is generated in that the oscillation movement can be changed by means of a drive 6 in the oscillation stroke and / or in the frequency and / or in the oscillation curve.
- This oscillation movement can be transmitted to the oscillating frame 3 by means of a hydraulic or an electrical or electro-mechanical drive 6.
- the frictional force is to be influenced via the lifting height of the oscillating movement of the oscillating frame 3, ie to be kept as small as possible.
- the frictional force as well as the surface quality can be influenced particularly by smaller lifting heights of the oscillating movements, for example in the form that the lifting height of the oscillating movement of the oscillating frame is adjusted to approx. 0.3 - 6 mm.
- the drive 6 engages at the point of attack 6a shown on the left in FIG. 2.
- the structure of the mold oscillation device is shown in more detail in FIG. 2: In a base frame 7, leaf spring assemblies 4a, 4b, bottom and 5a and 5b, top, run in pairs at an acute angle to one another.
- the drive 6 for the oscillatory movements can consist of a hydraulic drive 9 with a drive cylinder 9a, the drive rod 9b of which, with a screw connection, penetrates the oscillating frame 3 and is mounted therein.
- the swing frame 3 is supported on a cross member 10 for the drive 6.
- the leaf spring assemblies 4a, 4b and 5a, 5b are each clamped at their ends by means of a spring clamp 11, which is clear in FIG. 2.
- a base frame 7 carries the swing frame 3, which holds a bearing block 8 on a lower spar.
- the swing frame 3 is connected to the base frame 7 by clamping the leaf spring assemblies 4a, 4b (5a, 5b) via a lower holding plate 12 by means of bearing block screw connections 13 (each consisting of a screw, a threaded nut and a washer).
- bearing block screw connections 13 each consisting of a screw, a threaded nut and a washer.
- leaf spring assemblies 4a, 4b (on the other side 5a, 5b) are fastened to the base frame 7 by means of a respective lower holding plate 15 and screw connections 16.
- the arrangement of the leaf spring assemblies 4a, 4b is spatially completed by a protective plate 17.
- a centering rod 18 and lateral connecting screws 19 are also present.
- the leaf spring assemblies 5a, 5b are mounted in the upper part of the base frame 7 by means of upper holding plates 20 and upper screw connections 21.
- the upper bearing block 8 is provided by means of upper bearing block screw connections 22 and an upper stop 23.
- a base frame part 24 is also provided for the upper leaf spring assemblies 5a and 5b to delimit them from the leaf spring assembly 5b. Furthermore, connecting elements 25 are visible.
