Definitions

  • the invention relates to a mold for continuous casting, consisting of broad side plates, one of which forms a fixed side wall and the other a loose side wall, and adjustable narrow side plates which can be clamped by the broad side plates, and of adjusting cylinders which can be adjusted to a supporting force for the broad side plate forming the loose side wall.
  • Chill molds of this type are known in various designs.
  • both narrow side plates are generally adjustable by means of actuators, in particular hydraulic actuating cylinders, while one of the broad side plates is fixed in a frame in a position predetermined by adjustable support elements, for example adjusting screws, and thus forms a fixed side wall other broad side plate adjustable via actuators, in particular hydraulic actuating cylinders and thus forms a loose side wall.
  • actuators in particular hydraulic actuating cylinders
  • the narrow side plates are clamped non-positively in the desired position between the broad side plates during the casting operation.
  • the advantage of supporting the broad sides on actuating cylinders is that the supporting force can be adjusted. If the supporting force is exceeded by the strand forming in the mold, the broad side can deflect (EP 0 107 564 B1; DE 32 35 673 A1).
  • the pressurization of the actuating cylinder of the broad side plate is of crucial importance, because if the pressure drops, the jamming is lost with the result that the plates give in to the pressure in the mold and migrate.
  • the invention has for its object to provide a mold for continuous casting, in which a safe spring-elastic support of the broad side plate is guaranteed with little design effort.
  • the particular advantages of the mold according to the invention are that the clamping force of the broad side plate is applied by the actuating cylinder, so that there is a resilient support, and that if the pressure acting on the actuating cylinder fails, the clamping force is maintained by the additional support elements which then become effective.
  • a control device with a pressure switch is provided for the lockable support elements, which controls the actuators of the support elements.
  • the support elements are preferably clamping elements guided on rods.
  • the clamping elements can be operated hydraulically and can be designed as clamping cones. For design reasons, it is particularly advantageous if the clamping elements act on the piston rods of the actuating cylinders. In this In each case, an actuating cylinder and a clamping element can form a structural unit.
  • each actuating cylinder is coupled to the broadside plate via a spacing cylinder with a defined travel path such that the clamping force of the broad side plate is relaxed when the spacing cylinder is relieved of pressure is.
  • Narrow side plates 2, 3 and wide side plates 4, 5 are held in a frame 1. While the broad side plate 4 is adjustably supported directly on the frame 1, the broad side plate 5 is supported against the frame 1 by actuating cylinders 8, 9.
  • the narrow side plates 2, 3 can be adjusted to the desired width of the strand to be cast by means of actuators 6, 7 guided in frame 1 and supported thereon. During the casting process, the narrow side plates 2, 3 held by the broad side plates 4.5 by clamping.
  • the broad side plate 4 is fixed in the frame 1 and thus forms a fixed side wall
  • the broad side plate 5 is adjustable by means of the actuating cylinders 8, 9 held in the frame 1 and thus forms a loose side wall.
  • Each of the actuating cylinders 8.9 has the structure shown in FIG. 2.
  • An actuating cylinder 11 and a clamping element 12 in the form of a hydraulically actuated clamping cone are accommodated as a structural unit in a housing 10 fixed in the frame 1.
  • the clamping element 12 is arranged on the piston rod 13 of the actuating cylinder 11 and thus forms a support element for the adjustable broad side plate 5.
  • the free end of the piston rod 13 is coupled to the movable broad side plate 5 via a spacer cylinder 14.
  • Hydraulic pressure can be applied to the actuating cylinder 11 on both sides.
  • the actuating cylinder 11 is supplied with the pressure medium on its right side in the drawing by a first pressure medium source 15, a control valve 16 adjusted to the right in the drawing, a line A and a check valve 17.
  • Pressure medium is supplied to the check valve 17 from a second pressure medium source 18 via a control valve F via a control line F, through which the check valve 17 is held in the unlocked state. Because of a simple check valve 20 provided in another line F connected to the right side of the actuating cylinder 11, the pressure medium cannot flow away.
  • the left side of the Actuating cylinder 11 can be connected to the pressure medium source 15 by moving the control valve 16 into the left position. This connection is made in order to release or reset the broad side plate 5.
  • the hydraulically actuated clamping element 12 arranged on the piston rod 13 has a conical clamping piece 12a and a piston 12b arranged thereon on both sides with pressure medium.
  • the clamping element 12 is unlocked by supplying pressure medium via a line C with the control valve 19 in the right position. If the control valve 19 is brought into the left position, that is to say into the position shown in the figure, then pressure medium is supplied via the line D with the result that the clamping piece 12a clamps on the piston rod 13 and fixes it.
  • a control device 21 controls the control valves 16, 19 as a function of the pressure on the right side of the control cylinder 11, which is monitored by means of a pressure monitor 22.
  • the left side of the spacer cylinder 14 is connected via a line G to line A, so that both cylinders 11, 12 are acted upon with the same pressure.
  • the piston of the spacer cylinder 14 is held in the position shown in the drawing.
  • the operating pressure predetermined by the pressure medium source 15 is held on the actuating cylinder 11.
  • the adjustable broad side wall 5 is pressed with the clamping force corresponding to the pressure against the end faces of the narrow side walls 2, 3. Since pressure medium is simultaneously supplied via the control line E from the further pressure medium source 18 via a check valve 23, the check valve 17 is kept in the unlocked state.
  • the check valve 20 blocks against it. This means that the piston of the actuating cylinder 11 and thus also the broad side plate 5 is supported resiliently against the pressure of the pressure medium source 15.
  • the pressure is monitored by a pressure switch 22 and reported to the control device 21. If the pressure falls below a limit value, the control valve 19 is reversed into the position shown in the drawing. At the same time, the control valve 16 is reversed into the middle position shown in the drawing.
  • the result of these actuating processes is that the clamping element 12 clamps the piston rod 13, the check valve 17 is no longer held in the unlocked state and the right side of the piston of the actuating cylinder 11 is supplied with pressure medium via the check valve 20.
  • the fact that the actuating cylinder 11 remains in this position during the reaction time of the clamping element 12 is ensured by supplying pressure medium from a pressure medium reservoir 24.
  • the clamping element 12 is also activated and the lines A and G are switched off from the pressure medium supply and relieved of pressure.
  • the broad side plate 5 can then via the path defined by the piston of the spacer cylinder 14 back away.
  • control valve 16 is moved to the left when the clamping element 12 is released, so that pressure medium is supplied via line B to the left side of the actuating cylinder 11.
