Definitions
- the invention relates to a continuous casting plant, in particular for steel long products, according to the preamble of claim 1 and a process for continuous casting according to the preamble of claim 13.
- the liquid metal eg. As the liquid steel, filled in a cooled mold and continuously led away from this mold with shell formation as Giessstrang continuously.
- This casting strand is separated by a further cooling device, a so-called secondary cooling, along a line arranged one behind the other.
- the cooling nozzles must be accurately positioned and aligned and have the same spray characteristics, but on the other hand, an exact guidance of the casting strand along its guideway is important.
- the strand tends to be deformed due to thermal deformation from the guideway, e.g. sideways dodge. This shift immediately leads to uneven cooling water medium loading and thus to further displacement of the strand from its nominal position.
- the problem is particularly critical when small-sized strands (billets, about 100-160 mm square) are poured using high-intensity spray water cooling, so-called hard cooling.
- it can come from its arcuate guideway, if increased frictional forces occur in the mold area, and the relatively flexible strand is quasi stretched.
- guide rollers which are fixed or compliant (via spring assemblies ,, compressed air bellows, etc.) are mounted at a predetermined minimum distance from the strand, the compliant design is practically used only on the strand top.
- the present invention has for its object to provide a continuous casting plant of the type mentioned above and to propose a method for continuous casting in particular steel, with which the quality of the cast strand are significantly improved by a precise, with respect to the strand cross-section symmetrically distributed cooling can.
- the N ' times should be reduced when changing the casting plant to another casting format and maintenance.
- the other guide rollers are adjustable in a direction substantially perpendicular to the corresponding Giessstrang inhabit and the contact pressure of the respective roller is adjustable to the casting strand, it is ensured that the guide rollers constantly run through the clamping of the strand and the casting strand is held in its desired position in the guideway.
- the risk of thermal overloading of the rollers and damage to the strand surface is significantly reduced and ensures symmetrical cooling.
- the contact pressure of the strand to the centering rollers can be measured and a signal derived therefrom can be delivered to a control device.
- a targeted change in the cooling can be carried out locally, for example on a specific strand side, so that a central strand run is achieved virtually by the thermal route.
- FIG. 1 shows schematically a part (mold with the subsequent cooling chamber) of a continuous casting plant according to the invention in side view;
- FIG. 2 is a perspective view of a centering module as part of the continuous casting installation according to FIG. 1; FIG. and
- FIG. 3 the centering of Fig. 2 with a protective box for a control device.
- a continuous casting plant comprises a mold 1, into which the liquid metal, in particular steel, is filled and continuously removed from below this water-cooled mold 1 with the formation of a shell as cast strand 2.
- This casting strand is passed through a further cooling device, a so-called secondary cooling, thereby further cooled '.
- support rollers and spray elements 4 can be installed on the mold outlet as so-called foot roller stands or support segments. These are format-dependent and are replaced with the casting mold each time with the mold.
- the cooling device comprises a plurality of spray modules 3 arranged one behind the other, in which the guided along a guideway Giessstrang 2 with coolants, usually with water or a water-air mixture is applied.
- each cooling module 3 is equipped with a multiplicity of spray nozzles 5 designed as spray elements, which are preferably mounted in water-conducting spray mats 7.
- the spray mats 7 are controlled via an adjusting member 6 substantially concentric to the cast strand axis adjustable.
- sliding arms 6a are advantageously provided for the spray mats 7 at the inner or outer radius of the strand, or corresponding pivot arms 6b for lateral spray mats 7.
- a drive 6c connected to the sliding arms 6a or the swivel arms 6b is provided for this adjusting element 6.
- the strand without spray cooling, d h. be essentially cooled only by means of water-cooled rollers. It is all the more important in this case that the strand remains constantly in contact with all the guide rollers.
- the casting strand 2 passes through a plurality of successively arranged centering modules 10, each of which has a fixed, the target course of the guideway defining roller 11 for a strand side 2a and other guide rollers for the other strand sides.
- these further guide rollers 12, 13, 14 are arranged adjustable in a direction substantially perpendicular to the corresponding casting strand surfaces 2b, 2c, 2d independently of the casting strand cross-sectional shape (square, rectangle, round, double-T, etc.), as will be described below.
- the respective centering module 10 has a stationary frame 20.
- One of the other guide rollers, the upper guide roller 12, is held by a pivotable on the frame 20, bow-shaped holder 22 worn, such that it can be adjusted during its pivoting relative to the fixed mounted roller 11 and thereby pressed onto the strand side 2b.
- the pivoting of the holder 22 is preferably accomplished by means of an apparent from Fig. 2 hydraulic cylinder 25 via a rotatably connected to a pivot shaft 21 lever 26. When adjusting the hydraulic cylinder 25 and the lever 26, the pivot shaft 21 and with it also the bow-shaped holder 22 is pivoted accordingly.
- the two other lateral guide rollers 13, 14 are each supported by a respective fixed frame axis 31, 32 pivotable, sleeve-shaped part 33, 34, via two associated with the respective part flange 33a, 34a, in which the rollers are mounted ,
- the two sleeve-shaped parts 33, 34 are rotatably connected to each other via intermeshing tooth segments 35, 36.
- the part 34 is actuated or pivoted by a further hydraulic cylinder 40, wherein its pivoting on the tooth segments 35, 36 is also transmitted to the other part 33, so that the two guide rollers 13, 14 via the pivotable flange 33a, 34a exclusively symmetrical to each other, ie adjusted concentrically to the desired axis of the strand guide path and can be pressed according to the same amount on the two strand side surfaces 2c, 2d.
- the current contact pressure can be measured in the casting operation and at a pressure rise due to a thermally induced deformation of the casting strand a signal to a control device are issued, via which a targeted change in the cooling initiated and locally, for example on certain strand side, can be performed so that a centric strand run is achieved quasi on the thermal path.
- a control or regulation of the position and / or the contact force of the guide rollers 12, 13, 14 may be provided on the casting strand (2).
- this position and / or the contact force of the guide rollers can be set by comparing the setpoints with actual values.
- control cylinder Under the mentioned regenerative circuit of the control cylinder is meant a circuit in which the two cylinder pressure chamber are connected via line and the active pressure force results from the rod surface and the oil pressure. Only when the strand wants to escape from the desired position increases the pressure on the piston side and the cylinder is up to a predetermined max. Force blocked.
- the actuators preferably hydraulic cylinders 25, 40 and the control device, are advantageously located in a water-cooled, tightly sealed box 41 above the guide roller. Housed and protected by the heat radiation and the corrosive environment.
- the continuous casting plant according to the invention makes it possible to cast strands of various sizes without impairing the availability of the plant, since the respective change of the guide rolls or new positioning thereof is superfluous. This ensures high production quality in all strand formats.
- the complete centering modules can be quickly installed and removed in the cooling chamber by means of special manipulators positioned outside the cooling chamber.
- each module at the junction in the cooling chamber have a special connector unit by means of which all media and signals can be automatically connected.
- spray nozzles according to the invention could also be provided in a special system, which are contained in a plurality of spray modules (3) arranged one behind the other and can be controlled substantially concentrically to the cast strand axis, during which the guide rollers would be arranged in the conventional sense.
