Definitions

  • the invention relates to a continuous casting installation, the strand guide segments of which are provided with spray elements, in particular spray battens, which are distributed over the variably adjustable width of the strand and are divided into cooling zones and are connected to transverse distributor pipes.
  • the invention is therefore based on the object of improving the cooling system in a continuous caster of the type mentioned.
  • the outer spray battens arranged beyond the minimal strand side can be switched on or off depending on the respective strand width, preferably from outside the cooling chamber.
  • a width-dependent spray cooling can be achieved, which can be varied from outside the cooling chamber during the casting operation when the spray slats are switched on or off.
  • the openings of the transverse distributor pipe for the outer spray battens are assigned rotatable inner pipes with smaller circumferential recesses from the inside to the outside.
  • the spray battens arranged beyond the minimum strand width can thus be switched off or on successively from the inside out by turning the inner tubes which are concentrically inserted at the ends into the transverse distributor tubes.
  • the inner tubes can be rotated in a transverse distributor tube by means of a correspondingly coordinated angle of rotation so that the closed jacket of the inner tubes first enters the inflow opening to the outside Spray battens and with further twisting of the inner tubes gradually reaches the position covering the spray battens which follow inwards to the minimum strand width. It is then switched on by reversing the direction of rotation from the inside to the outside.
  • the outer circumferential recesses can advantageously be formed as a cylindrical bore and the middle and the inner circumferential recesses as radial grooves with a first and a second, larger radian measure.
  • the circumferential grooves provided in the inner tubes depending on the spray battens can thus be produced simply by boring and / or milling.
  • the spray battens can be switched on or off manually, for example, using a key that leads to the outside of the cooling chamber and is attached to the outer square.
  • One embodiment of the invention provides that the inner tubes of the cross distributor tubes of several cooling zones are connected to one another via a linkage.
  • the connecting rod allows the inner tubes of all cooling zones to be rotated simultaneously with a uniform adjustment movement.
  • the spray battens can also be opened or closed in pairs, that is to say to the right and left of the strand width, a spray battens.
  • FIG. 1 shows in detail a strand guide segment 1, indicated by dash-dotted lines, several of which are arranged one behind the other in the strand running direction 2 and enclose and guide a cast strand 3 (see FIG. 2) between rollers.
  • the strand guide segment is provided with a cooling chamber which, in the exemplary embodiment, is divided into three cooling zones 4 to 6 in the strand running direction 2.
  • Each cooling zone 4 to 6 has several Spacing 7 or 8a, 8b, 8c arranged next to one another over the width of the strand guide segment 1.
  • the middle spray battens 7 cover the range of the minimum width of the strand to be cast on the continuous casting machine, while the outer spray battens 8a to 8c arranged on both sides cover the range of the maximum strand width.
  • the spray battens 7 and 8a, 8b, 8c of each cooling zone 4, 5, 6 are connected to a common cross-distributor pipe 9, via which the cooling water to be sprayed onto the strand 3 is supplied from a water supply (not shown).
  • inner tubes 11, 11 are inserted concentrically into the transverse distributor tubes 9 at both ends. 12 arranged as shown in Figure 3. They are closed at their free ends, that is to say the outer end faces, are provided there with an outer square 13 and are also screwed to a web 14.
  • the bolts 15 penetrating the web 14 and the end wall of the inner tubes 11, 12 are screwed to holding blocks 16 inserted into the inner tubes 11, 12; these include between them a coupling tube 17 which connects the two inner tubes 11, 12 to one another and fixes them in a movement-dependent manner.
  • the length of the inner tubes 11, 12 immersed in the transverse distributor tube 9 is dimensioned such that a superimposition of the innermost spray bar 8a of the spray bars 8a to 8c, which can be switched on and off, is ensured.
  • the cross distributor pipe 9 has openings 18 for the spray battens 7 or 8a to 8c; These are assigned in the inner tubes 11 and 12 circumferential recesses 19, 20, 21, which in the area of the outer spray battens 8c as a cylindrical bore 19 and in the area of the middle and inner spray battens 8b, 8a as radial grooves 20, 21 are formed, of which the circumferential recess or radial groove 20 assigned to the middle spray batten 8b has a smaller radian dimension ⁇ 'than that of the radial groove 21 assigned to the outer spray batten 8c with the radian dimension '(see FIGS. 4a to 4c).
  • the inflow openings 18 in the transverse distributor pipes 9 are open for all spray battens 7 or 8a to 8c. If a narrower strand format is to be cast and lateral extrusion of the strand is to be prevented, only the inner tubes 11, 12 need to be rotated about their longitudinal axis. This can be done by means of a socket wrench 22 (cf. FIG. 3) which is plugged onto the outer square 13 of the inner tubes 11 and 12 from outside the cooling chamber.
  • both inner tubes 11, 12 are rotated at the same time, that is to say the spray battens 8a, 8b, 8c, which can be switched on and off, are first paired, then the outer ones middle and then the inner spray slats 8c, 8b and 8a closed.
  • the webs 14 on the drive side of the transverse distributor pipes 9 are designed as a movement joint for a linkage 23 connecting the individual cooling zones 4, 5, 6, they can be opened by only one drive or by means of simply switch on and off the spray battens 8a, 8b, 8c of all the cooling zones at the outer square 13 of an inner tube.
  • a rotary movement of the inner tubes 11, 12 by the angle ⁇ causes the jacket recesses or cylindrical bores 19 assigned to the outer spray battens 8c in the inner tubes 11, 12 from their aligned position with the associated openings 18 in the transverse distributor tubes 9 (see FIGS.
