Definitions

  • the invention relates to a device for the adjustable adjustment of a stopper of a distribution channel or a metallurgical vessel in a (billet, block or slab) continuous casting installation, the stopper being connected to a crossbar or stopper flag arranged over the distributor channel or the metallurgical vessel, which in turn is connected to a support rod that can be moved up and down in a vertical guide.
  • Devices or plug lifters of this type are characterized by large tolerances and thus a correspondingly large mechanical play, with the consequence of a correspondingly low precision of the plug movement, which necessitates constant readjustment of the plug position in order to achieve a predetermined pouring rate.
  • the above-mentioned problem becomes particularly important when formats of ⁇ 160 mm2 are to be cast. With these formats, tolerances in the plug mechanism are highly undesirable.
  • the present invention has for its object to provide a practically tolerance-free plug mechanism so that the problems mentioned no longer occur. At the same time, the manufacturing and maintenance costs of the novel plug mechanism should be considerably reduced, or at least not exceed the current effort for this.
  • the guide rod preferably comprises a square profile section which is surrounded by a corresponding square guide housing, the latter being openable for assembly, disassembly and maintenance.
  • a square guide housing which is openable for assembly, disassembly and maintenance.
  • the one square section 1 of an up and down movable support rod for a plug guide 22, not shown in FIGS. 1 and 2 is formed by two U-profiles 2 and 3 welded firmly at right angles to one another, at their free longitudinal edges or not welded legs via double hinges 6
  • U profiles 7 are articulated so that they can be pivoted in a position in which they form a passage complementary to the square section 1 with the welded U profiles 2 and 3 .
  • the welding of the two aforementioned U-profiles 2 and 3 is carried out by means of an L-profile 4 in the area of the abutting longitudinal edges of the two U-profiles 2 and 3.
  • the above-mentioned articulation of the U-profiles 7 is used for mounting or dismounting the vertical rod guide it can be opened without much effort.
  • the aforementioned vertical guide is characterized by support rollers 10 clamped between the square section 1 of the support rod and the guide housing defined by the aforementioned U-profiles 2, 3 and 7, the support rollers 10 each being shown by flexible support roller belts in accordance with FIGS. 2 and 3a, 3b 11 are held.
  • Each support roller band 11 is fastened to the support rod or its square section 1 on the one hand and to the associated support surface of the guide housing 2, 3, 7 on the other hand to form a support roller pocket (see FIGS. 2 and 3a).
  • the square section 1 of the support rod is on all four sides supported against the guide housing 2, 3, 7 by the support rollers 10, with two support rollers 10 being arranged at an axial distance from one another on each side, in each case in the diametrical end region of the guide housing 2, 3, 7 Part 7 of the guide housing which can be pivoted is only partially opened without dismantling the support roller belts on this part.
  • the support roller belts 11 To completely open the guide housing, the support roller belts 11 must first be released or removed from the pivotable housing part 7. Although this effort is not particularly great, it can be avoided by the measures according to FIGS. 5 and 6.
  • the support roller belts 11 are provided with a type of perforation, which preferably cooperate with complementarily profiled peripheral surfaces of the support rollers 10 in order to avoid a relative movement between support rollers 10 and associated support roller belts 11.
  • the circumferential surfaces of the support rollers 10 can each have a toothing that extends in the longitudinal axis of the support roller, which corresponds to a complementary toothing on the square section 1 of the support rod on the one hand and the respectively assigned inside of the guide housing 2, 3, 7 on the other hand.
  • the square section 1 of the support rod 5 has recesses, of which four recesses are designed as elongated holes 12, 13, which are each arranged at an axial distance from one another in a cross, ie penetrating one another at right angles to one another.
  • a total of four tension rods 8 are passed through these elongated holes 12, 13, each of which is provided with a collar 14 at one end.
  • the tension rods 8 also extend through the opposite sides of the guide housing or opposite webs of the U-profiles 2, 7 and 3, 7 forming the guide housing.
  • the ends 14 of the tie rods 8, which are diametrical to the collar 14, are each provided with a screw thread onto which a nut 42 can be screwed.
  • the guide housing 2, 3, 7 is held together by means of the tension rods 8, with the support rollers 10 being appropriately clamped in.
  • the suitable prestressing takes place counter to the action of spring elements arranged between the collar 14 of each tension rod 8 and the associated side of the guide housing 2, 3, 7. in particular thermodynamic spring elements according to DE-B-24 06 006.
  • the aforementioned spring elements 9 are each effective on the pivotably mounted U-profiles 7, for purely assembly-technical reasons.
  • the tension rods 8 and the aforementioned spring elements 9 the necessary clamping of the support rollers 10 is adjustable. At the same time, a play-free vertical guidance of the support rod and thus of the plug arranged on the plug lug 22 is obtained in this way.
  • the support rollers 10 support the square section 1 multifunctionally. They perform a pure roller movement during the vertical movement of the support rod or the square section 1 thereof.
  • the vertical guidance described is therefore practically frictionless. The wear and thus the maintenance effort are correspondingly low.
  • the aforementioned perforation of the support roller belts 11 is preferably characterized by holes with a diameter of approximately 10 mm. This measure also promotes the failure of any dirt.
  • a complementary profiling of the peripheral surface of the support rollers 10 is not absolutely necessary, but - as in connection with the avoidance of any slippage above - advantageous.
  • the fifth recess 15 in the square section 1 is used for the lateral insertion of a block-piston-cylinder unit 16, by means of which the support rod can be moved back and forth or up and down.
  • the aforementioned piston-cylinder unit 16 can accordingly be supported on the guide housing 2, 3, 7 on the one hand and on the support rod, namely on the square section 1 thereof on the other hand.
  • It comprises two piston rods 19, 20 which can be pulled out coaxially and diametrically from the cylinder housing, and a third piston rod 21 which can be pulled out of the housing, the two first-mentioned piston rods 19, 20 being located within the lateral recess 15 on the square section 1 or the support rod for the up and down movement thereof attack while by means of the last-mentioned piston rod 21, the piston-cylinder unit 16 is fixed on the stationary or on the guide housing 2, 3, 7 attached to the distributor trough.
  • the latter piston rod 21 is effective at a lateral distance from the first two piston rods 19, 20. It also extends parallel to these (see cylinder or piston rod central axes 17, 18 in FIG. 2).
  • the lateral recess 15 in the square section 1 of the supporting rod is assigned a corresponding passage 43 in the guide housing, through which the aforementioned piston-cylinder unit 16 can be inserted into the lateral recess 15 of the square section 1 of the supporting rod with the two piston rods 19, 20 in front.
  • all three pistons and thus piston rods 19, 20, 21 are extended.
  • the diametrical Effective piston rods 19, 20 are supported on the top and bottom of the lateral recess 15 of the square section 1, while the piston rod 21, which is further out, is supported on the guide housing or on a support block 44 connected thereto, with the piston-cylinder Unit 16 on the guide housing 2, 3, 7.
  • the piston rods 19, 20 engaging the square section 1 move in the opposite direction with a stroke command through the hydraulics assigned to these piston rods, with constant "excess force” in the "extend” direction, ie upward in FIG Opening the stopper.
  • the hydraulic circuit according to FIG. 4 illustrates the mode of operation of the hydraulic system acting on the square section 1, the force support of the piston-cylinder unit 16 on the outer guide housing 7 not being shown for the sake of a better overview.
  • the diametrically effective piston rods 19, 20 or their associated pistons are each under pressure during operation, with either the upper or the lower piston being under pressure relative to the diametrically active piston, depending on the desired direction of movement of the support rod and thus of the stopper.
  • the cylinder spaces 24, 25 assigned to the diametrically effective pistons and each free of piston rods are fluid-connected (connecting line 26), this fluid connection 26 being used to build up a pressure that moves the two pistons apart. In practice, this pressure is approximately 180 to 250 bar. Because of this high pressure, the two diametrically effective pistons are practically firmly coupled to one another.
  • Said fluid connection 26 can be connected to either the pump “P” or the tank “T” of the hydraulic system via a check valve 27 that can only be opened in the direction of this, and a 3/4 way valve 28, specifically via a line 40, whereby between the check valve 27 and the aforementioned Fluid connection 26 branches off a line 29 to tank "T", in which an adjustable pressure relief valve 30 is arranged.
  • the cylinder spaces 31, 32 penetrated by the diametrically effective piston rods 19, 20 can each be connected alternatively to the pump “P” or the tank “T” via a 3/4 way valve 33, lines 36 from the corresponding connecting lines 34, 35 in each case , 37 branch off to a switching valve 38, by means of which either connecting line 34, 35 or none of them can be connected via a line 39 to the 3/4 way valve 28, to which the fluid connection 26 between the two piston rod-free cylinder spaces 24, 25 is also connected .
  • the check valve 27 arranged in the latter connection 40 can be unblocked via a pressure line 41 branching from the line 39 connecting the switching valve 38 to the latter 3/4 way valve 28, with a corresponding reduction in the piston spreading pressure in the fluid connection 26 between the two piston rod-free cylinder spaces 24 , 25, as long as the 3/4-way valve 28 is in the right relaxation position in FIG. 4.
  • line 40 is connected to tank "T".
  • the line 39 and thus also the pressure line 41 is in this position of the valve 28 with the pump "P" in connection with the result that the check valve 27 is unlocked, so that through the check valve 27 the pressure in the fluid connection 26 via the line 40 to the tank "T" can be dismantled.
  • the pressure in the fluid connection 26 is built up in the reverse manner, namely in the position of the 3/4 way valve 28 on the left in FIG. 4.
  • the pump "P” is via the check valve 27 and the line 40 with the fluid connection 26 connected.
  • the tank “T” is connected via line 39 to the switching valve 38, which is in the so-called “h" position, ie in FIG. 4 in the right one, both when the pressure in the fluid connection 26 is reduced and when it builds up Position is in which the line 39 is fluidly connected to both connecting lines 34, 35 and 36, 37, respectively.
  • the switching valve 38 and the 3/4-way valve 28 are brought into the positions shown in FIG. 4. In these positions, the line 39 is depressurized.
  • the check valve 27 is effective so that the pressure built up in the fluid connection 26 remains, the setting of this pressure being carried out by the pressure limiting valve 30.
  • the connecting lines 36, 35 are decoupled from the 3/4-way valve 28, so that only the 3/4-way valve 33 directly associated with the connecting lines 34, 35 is effective. This valve then causes the piston rods 19, 20 to move up and down. All valves are preferably solenoid controlled.
  • the two diametrical pistons act like a single piston with two diametrically extending piston rods.
  • the pressure in the fluid connection 26 is reduced in the aforementioned manner.
  • the pressure is built up in this fluid connection in the manner described; d. H. the piston-cylinder unit 16 is "cocked” in the manner described.
  • the valves 28 and 38 are brought into the operating position in the manner also described above, namely as shown in FIG. 4, so that only the 3/4 for the synchronous upward and downward movement of the piston rods 19, 20 Directional valve 33 is used.
  • FIG. 1 part of the distribution channel is identified in FIG. 1 by reference number 5. Furthermore, the opening direction of the U-profiles 7 is indicated by the arrows 45 in FIG. 1.

  • the pivotably mounted part of the supporting rod guide housing ie the pivotably supported U-profiles 7, also has horizontal grooves 47 on the inside for receiving the aforementioned rectangular frame 46 when the supporting rod guide housing is closed (see in particular FIG. 6).
  • the rectangular frame 46 is adapted to the free cross section of the support rod guide housing, that is to say it is square in the case shown.
  • the support rod guide housing 2, 3, 7 can also be opened without dismantling the support roller belts 11 assigned to the pivotable housing part 7.

  • the support roller 10 rolls upwards between the guide housing and the support rod, specifically because of the elastic clamping between the guide housing and the support rod without play or slip.
  • the end sections 50 come into contact with the projection-like stops 11 ', which ensures that the support roller 10 is always aligned or remains transverse to the direction of movement of the support rod 1.
