Definitions

  • An adjustable plate mold for continuous casting incorporating a support frame and longitudinal walls and transverse walls supported at the support frame, said longitudinal walls and transverse walls limiting the mold compartment.
  • the longitudinal walls are slidingly arranged at the side facing away from the hollow mold compartment upon support plates for expansion and contraction and the transverse walls are equipped with adjustment devices supported by the support frame.
  • the adjustment devices positively are connected, on the one hand, with the transverse walls and, on the other hand, with the support frame in the adjustment directions.
  • Exchangeable impact or stop gauges corresponding to the momentary reference value of a mold dimension are provided between the transverse walls and impact or stop surfaces at the support frame and the transverse walls can be fixedly clamped between the longitudinal walls.
  • Each adjustment device has associated therewith a coupling for interrupting the positive connection. During the casting operation this coupling permits movement of the associated fixedly clamped transverse wall with respect to the impact surfaces in the direction of the mold compartment and back again.
  • adjustable plate molds By displacing the transverse walls of such molds it is possible to vary the width of the strand format or by exchanging the transverse walls for others having a different dimension it is possible to vary the thickness of the strand. Adjustment devices are arranged between these transverse walls and the support frame for the rapid and exact adjustment of these transverse walls. As a general rule such adjustment devices consist of threaded spindles which are hingedly connected with the transverse wall and by threading or worm gears with the support frame. Connections such as hinges, threads and worms or the like provide a positive connection in the axial direction of the spindle. The use of such adjustment devices is a prerequisite for realizing a mechanized orautomated adjustment. 7
  • the walls of the mold heat-up. As a result thereof there is formed throughout the walls a temperature gradient between the sides confronting the hollow mold compartment and the cooled wall sides facing away from such hollow mold compartment. Such temperature gradient produces stresses at the walls of the mold, resulting in expansion and contraction phenomena.
  • the transverse walls of which are connected through the agency of adjustment devices with the support frame and supported thereat during expansion of the longitudinal walls at the start of casting or during contraction of such walls upon the completion of the casting operation there occurs relative movement between the transverse walls and the longitudinal walls at the joints.
  • the state-of-the-art is familiar with plate molds in which the longitudinal walls, at the side facing away from the hollow mold compartment, are arranged at support plates such that they can slide in a manner that after overcoming the prevailing friction they can expand and contract.
  • the transverse walls By means of tension boltsuconnected with the transverse walls, and which are mounted free of play in bores of the longitudinal walls formed of copper, the transverse walls are fixedly clamped.
  • the transverse walls move together with the longitudinal walls and there is thus prevented relative movement between the longitudinaland transverse walls at the joints.
  • Such molds possess the drawback that owing to the irregular expansion of the longitudinal walls the mold reference value i.e.
  • the desired mold dimension during casting operation and the reference taper of the transverse walls can change in an uncontrolled fashion after the mold adjustment and therefore cause defects in the cast strand.
  • a corresponding mold which requires high investment cost.
  • an adjustable plate mold which consists of a support frame and longitudinaland transverse walls equipped with cooling devices and supported at the support frame.
  • the transverse walls are provided with adjustment devices supported at the support frame.
  • the transverse walls are fixedly clampable between the longitudinal walls. At the start of casting or at the end of casting respectively there occur at such molds, at the joints between the transverse walls and the longitudinal walls which respectively expand and contract, relative movements which subject these longitudinaland transverse walls to wear. Owing to this wear the quality of the surface of the cast strand is impaired and additionally the useful life of the mold is shortened.
  • Another and more specific object of the present invention aims at, on the one hand, rigidly supporting the transverse walls for predetermined mold reference dimensions at the support frame by means of adjustment devices, and, on the other hand, reducing the wear at the mold walls as well as avoiding strand defects caused by the mold.
  • adjustable plate mold which is relatively simple in design, extremely reliable in operation, quite easy to set-up and use, subject to lesser wear than was the case for existing state-of-the-art plate mold constructions, and permits accurate and easy adjustment of the transverse walls of the mold to alter the format or dimensions of the cast strand.
  • Each of these adjustment devices is positively connected, on the one hand, with its associated transverse wall and, on the other hand, with the'support frame in the mold adjustment directions of the transverse walls.
  • exchangeable stop or impact gauges corresponding to the momentary reference value'of a mold dimension i.e.,'the-desired mold dimension during casting are provided between the transverse walls and stop or impact surfaces at the support frame, and the transverse walls can be fixedly clamped between the longitudinal' walls.
  • a coupling for interrupting the connection between the. transverse wall and the support frame is operatively associated with each adjustment device and this coupling, during the casting operation, permits movement of the fixedly clamped transverse wall with .respect tothe stop surfaces in the direction of the hollow mold compartment and back again.
  • the coupling for'interrupting the'positive connection between the associatedtransverse wall and the support frame can be advantageously arranged between the adjustment device and the support'frame or the adjustmentdevice and the-transverse wall.
  • the coupling is advantageously designed in such a way that a disk'which is connected in a positive fashion via threads with the spindle can be slidingly guided at the support frame axially with respect to the spindle and that between a support surface of the support frame and 'the disk there is arranged a pre-biased package of springs in-such a way that the spring force urges the associated transverse wall against the stop or impact gauges.
  • the coupling consists of a coupling element which cooperates with the spindle for selectively separating and connecting the spindle with the corresponding-transverse wall or the support frame.
  • FIG. 1 is a top plan view of a partially sectionally il lustrated plate mold in hot condition, in other words when subjected to thermal action;
  • FlG.2 is aplan view ofithe mold of FIG. 1 in cold condition
  • FIG. 3 is'a plan view of'a different embodiment of partially depicted mold.
  • FIG. 4 is a sectional view of the mold construction of FIG. 3, taken substantially along the line IV-IV thereof, and turnedi-in the plan of-the drawing.
  • FIG. 1 longitudinally 5 extending walls 3 and transversely extending walls 4 ,(only oneof the transverse walls 4 has, been shown) which delimit a mold compartment-or cavity 2 are supportedupon a support frame 1 which extends completely about-a mold 6.
  • the longitudinal extending or longitudinal walls3 are slidingly arranged at the side facing away from the mold compartment 2 upon sup-' port plates v5 in such a manner thatafter overcoming the prevailing friction-they can expand and contract.
  • the transversely extending or transverse walls 4 are adjustable .by means of the spindles 8.:Each of these spindles 8 is associated with one of the transverse walls and they are supported at the support frame 1 and equipped with a suitable and therefore not particularly illustrated drive.
  • the spindle-adjustment devices may be the same for each of the transversewalls 4 the description will be convenientlyv defined to one of the transverse walls and 1 its associated adjustment device.
  • the transversewalls 4' can be fixedly clamped betweenthe longisprings 14, which cooperates with the disk 18, serves as.
  • FIG. '1 depicts the mold 6 in its hot condition or directly after there has been undertaken an adjustment of I the format or dimension of the strand.
  • the mold walls 3 and 4 expand, especially the longitudinal walls 3.
  • expansions in the order of about 3 millimeters have been measured at the copper longitudinal walls.
  • Only at the beginning of thefirst casting following a strand format adjustment does thereoccura relative movement between the rigidly supported transverse walls 4 and the expanding longitudinal walls 3,,and which corresponds in magnitude to the maximum possible expansion of the longitudinal walls.
  • the longitudinal walls 3 again contract and entrain the transverse walls 4 which are fixedly clamped between the longitudinal walls in the direction of the mold compartment or cavity 2 while compressing the package of springs 14 by an amount which corresponds to the expansion which has occurred at the start of casting.
  • FIG. 2 the mold 6 is shown in its cold condition.
  • the set or package of springs 14 and the slidingly guided disk 18 render possible movement of the spindle 8 in axial direction and therefore a movement of the associated fixedly clamped transverse wall 4 away from the stop or impact surfaces 19 in the direction of the mold compartment 2.
  • the package of springs 14 can be pre-biased to the desired degree.
  • this gap 20 closes upon reaching the maximum expansion of the longitudinal walls 3, so that no further relative movement can occur between such walls 3 and the transverse wall 4, yet the mold reference size or dimension remains constant for each casting.
  • FIGS. 1 and 2 there has been provided for the adjustment element 8 an elastic coupling for interrupting the positive connection
  • Reference character 21 designates another spindle for adjusting the associated transverse wall 4 and which can move such transverse wall 4 in the adjustment directions 15.
  • a movable coupling bolt 22 cooperating with the spindle 21 there can be selectively established or interrupted a positive connection which acts in the adjustment directions, between the transverse wall 4 and the spindle 21.'
  • the coupling bolt 22 is coupled-in or engaged in the manner depicted in FIG. 4.
  • the coupling bolt 22 is raised i.e., pulled out and therefore the connection between the associated transverse wall 4 and the support frame 1 is disconnected. This renders possible movement of the transverse wall 4 away from the stops 19 in the direction of the mold compartment 2 and back again.
  • the coupling 22 is arranged between the spindle 21 and the associated transverse wall 4. Depending upon the available space such coupling can be, however, also installed between the spindle 21 and the support frame 1.
