Definitions
- the invention relates to a strip caster, in particular for the strip casting of steel.
- the casting thickness of the strip can largely be optimally selected (e.g. approx. 10 mm) in accordance with the required thickness of the hot rolled strip (1 to 3 mm) and the required hot deformation to achieve sufficient material properties.
- a device for the continuous casting of metal which has a feed device for liquid metal, a carrier tape for liquid and solidified metal and side boundaries tightly against the carrier tape.
- the side boundaries are attached to the carrier tape in the manner of a link chain.
- Such a construction is technically very complex. It is also essentially only suitable for relatively small bandwidths. In the case of larger bandwidths, the tension in the carrier brought about by the thermal load is substantially higher than in the case of narrow bands, so that the construction of the chain-like circumferential side boundary, which acts as a stiffener, cannot be used with large bandwidths.
- the feed device and / or the side boundaries are designed so that they can vibrate in the plane of the carrier tape and are connected to a device for generating vibrations.
- This measure prevents the sticking of solidified material.
- the vibrations of the feed devices and / or the side boundaries are essentially perpendicular to the conveying direction of the belt. The vibration takes place in the plane of the carrier belt or the forgotten steel belt, but transversely to the direction of conveyance. This has the advantage that the design effort is less than in the case of an oscillation in the conveying direction in which the side boundary would have to be guided exactly over the entire length.
- the vibration in the area of the metallurgical length (from the casting area to solidification of the strip) can advantageously be set optimally, for example by dividing the side boundaries in this area into individual sections, each with the optimum frequency and amplitude.
- the side wall boundaries can be set at an angle to one another. This applies both to the opposite side wall boundaries and to the sections that may be present on the respective side. As a result, the uniformity of the strip thickness over the entire width can be improved on the forgotten strip.
- side boundaries are also inclined with respect to the perpendicular to the surface of the carrier tape.
- the side wall boundaries consist of water-cooled hollow profiles.
- the devices for generating the vibrations are preferably eccentric drives, but electromagnets or hydraulic cylinders can also be used.
- the waveform can be sinusoidal, sawtooth-shaped or trapezoidal.
- the stroke frequency is, for example, 50 Hz with a stroke of, for example, 0.5 mm.
- the cooling water is supplied via flexible hoses.
- a layer of temperature-resistant sealing material in particular of ceramic fiber felt, is arranged for sealing between the side boundaries and the covers.
- a corresponding seal is provided between the feed device and the carrier tape, an aluminum sheet preferably being inserted between the carrier tape and the seal, so that in the event of an oscillation there is only a relative movement between the felt layer and the aluminum sheet.
- the feed device and the side boundaries are preferably held by coil springs.
- the boundaries can simultaneously oscillate both perpendicularly and parallel to the belt movement (casting direction), so that overall a thrust force also acts on the belt edge in the casting direction.
- the vibration has components in all three spatial directions.
- the vibration can take place perpendicular to the belt surface.
- the vibrations are excited by strikes in the longitudinal or transverse direction of the side boundary. In this way, longitudinal waves can suddenly be applied, with which the adherence can be effectively prevented.
