Definitions
- the invention relates to a method for treating a continuous casting producible cast strand, in particular of thin slabs, in a subsequent Hot strip mill with compensation furnace and with at least one rolling stand be reduced in thickness. Furthermore, the invention relates to a device for carrying out the method according to the invention.
- EP 0 360 480 A2 discloses a process for descaling metal strands known. This bending means are used with which bent the metal strand can be. In the bent area, the metal strand is then filled with water charged to remove the tinder. However, this solution does not provide any specific references to the treatment of oscillation marks of continuously cast Metal strands.
- JP 61-269925 A discloses equally such an arrangement, with the tinder can be removed from a metal strand. Again, there are none Indications of the treatment of a continuously cast metal strand, the oscillation marks having.
- the invention has for its object to provide a method and a device, through which the difficulties in cleaning the surfaces of Continuous casting, especially in thin slabs, and there especially and overcome in the oscillation marks. Also should be an undesirable strong cooling effect in the cast product using as small amounts as possible be prevented by pressurized water.
- An embodiment of the invention provides that for this purpose the cast strand sinusoidal or is deflected approximately sinusoidally.
- Such a sinusoidal or nearly sinusoidal deflection ensures an approximately uniform increase and decrease of the surface tension, whereby damage to the Gußgeheges is avoided.
- the method according to the invention further provides that the distance between the spray nozzles and the water-sprayed surface of the cast strand continuously measured and kept constant. This will become the working parameters when using the hard cleaning jets of water largely constant held.
- the pressure of the spray continuously controlled and maintained at a high pressure level.
- An advantageous embodiment of the method further provides that the Casting strand with a number each running in parallel planes and in series arranged water jets is applied, the planes at an angle to a the transport direction of the cast strand perpendicular intersecting planes lie and the water jets obliquely aligned to the surface of the cast strand are.
- a further improvement of the cleaning effect can also be achieved be that the water jets with the spray nozzles generating them the spray bar are reciprocable in the spray level.
- a cast strand producible in the continuous casting process in particular of thin slabs
- the cast strand in a subsequent hot strip mill with compensation furnace and is reduced in thickness with at least one rolling mill is at the end of Strand support and before the inlet into the equalization furnace or before the inlet into the rolling stands between a pair of upstream Richtertreiberrollen and a Pair of outlet side bending drive rollers a Entzu concerningsstation available
- the at least two spaced apart in the transport direction of the cast strand, each other has opposing deflection bends, which on each opposite side of the Casting Spray bar with spray nozzles arranged in an oblique plane are associated with the deflection bending rollers controlled actuating cylinder and encoder assigned.
- the area of a continuous casting plant shown in FIG. 1 shows the continuous casting machine 28 with downstream strand support 10 for guiding and supporting the Casting 1, in particular a thin slab.
- the thin slab gets behind the continuous casting plant in a hot strip mill 32 with compensation furnace 11 and with several rolling stands 33 reduced thickness. Between the equalizing furnace 11 and the first rolling stand 33, a crop shear 31 is arranged.
- the thin slab 1 im Cooperation with the outlet side Biegetrreiberrollen 13 by the Entzu mattersstation 14 through it.
- Located in this Entzu mattersstation 14 there are two opposing deflection benders 15 and 16 respectively.
- the deflection bending rollers 15, 16 are controlled actuating cylinders 23, 24 and Weggeber 25, 26 assigned.
- the deflection bending rollers 15, 16 are either weggeregelt or can be adjusted with load-controlled spacing.
- the adjusting cylinders 23, 24 control means for monitoring the deflection 4, 5 or the deflection forces to be assigned.
- the Entzu matterssstation 14 with a protective box 27 casings.
- the thin slab 1 with a number each in parallel planes x-x extending and arranged in series Water jets 8, 9 is applied, wherein the planes x-x at an angle ⁇ or ⁇ to a transport direction of the slab perpendicular intersecting plane y-y and the water jets 8, 9 obliquely to the surface 2, 3 of the thin slab 1 are alignable.
- the water jets 8, 9 are in particular the Oscillation marks 30 cleaned to the bottom.
- the water jets 8, 9 with the spray bar generating them 17, 18 be reciprocated in the plane y-y.
- the water jets can do this 8.9 either according to Fig. 3b and Fig. 4 obliquely against the transport direction 34th be directed to the slab 1. But you can also be aligned to the transport direction 34 be the choice of this orientation depending on the prevailing Operating parameters can be determined by the expert from case to case.
- the descaling device with the claimed Characteristics (Fig. 2) even before the inlet of the thin slab in the rolling stands 33 are provided.
