Definitions

  • the invention relates to the continuous casting of metals. More specifically, it relates to devices for the lateral confinement of liquid metal in the ingot molds of machines for the continuous casting of thin strips, the casting space of which is limited by the close side surfaces of two cylinders with horizontal axes, energetically cooled internally and placed rotating in opposite directions.
  • French patent application FR9408319 brings an improvement to this operating mode and to those which would derive therefrom by providing means making it possible to slightly deform the lateral faces by modulating the pressure applied to their different zones.
  • temporary or permanent inequalities are taken into account in the forces exerted on the different parts of the lateral faces by the cylinders.
  • Such inequalities can occur, for example, in the event of parasitic solidification of infiltrated metal between the lateral face and a cylinder, or when the two edges of the cylinders against which the lateral face is applied are not perfectly coplanar and orthogonal to the axes of the axes. cylinders.
  • the object of the invention is to provide the operator with the means of imposing on the lateral face a controlled wear which would not be greater than what would be strictly necessary for the smooth running of the casting.
  • the subject of the invention is a device for supporting a lateral face of a continuous casting installation between cylinders of thin metallic products of the type comprising two cooled cylinders with horizontal axes, two lateral faces applied against the edges of the cylinders, said support device comprising a carriage which can be moved on command in a direction parallel to the axes of the cylinders, a pushing device carried by said carriage, and a plate secured to the side face, connected to said pushing device by means of '' a thrust plate and thrust members bearing on said thrust plate and said plate, characterized in that said plate comprises at least one tie passing through the plate thrust and the free end of which is fitted with a stop which can be applied against the rear face of said thrust plate.
  • the plate supporting the small face is equipped with one or more tie rods passing through the thrust plate, and whose free ends can abut against the rear face of the thrust plate.
  • the pushing members which normally tend to move the plate away from the pushing plate to apply the side face against the cylinders causing its wear, see their action limited when this wear has become sufficiently pronounced for this coming into abutment to be carried out. There is then only a minimal friction between the side face and the cylinders, and the wear of the side face is almost canceled.
  • Figure 1 shows a side part of a casting machine between two close cylinders with horizontal axes rotated and internally cooled, of which only one of the cylinders 1 is visible.
  • the other side of the machine is similarly equipped.
  • the casting space defined by the two cylinders is closed laterally by a lateral face 2 of refractory material, the front face of which is applied against the edges 3 of the cylinders 1.
  • the lateral face 2 is fixed by its rear face to a plate 4 which is made of a material such as a metallic material. This plate 4 is preferably cooled to prevent it from being affected by deformations of purely thermal origin.
  • the displacements and the bearing force on the cylinders 1 of the lateral face 2 are controlled by an assembly which acts on the plate 4 and which will be described in more detail.
  • it comprises a carriage 5 movable for control in a direction parallel to the axes of cylinders 1.
  • a pushing device 6 such as a jack (or a group of jacks) controlled by pressure or in position, comprising a rod 7 movable when ordered, always in the same direction parallel to the axes of the cylinders 1.
  • the rod 7 attacks a thrust plate 8, which itself carries a set of thrust members 9, 9 ', 9 ", 9"', such as springs or actuated jacks, exerting their force on the rear face 10 of the plate 4.
  • These members are distributed over an area whose shape preferably corresponds to that of the lateral face 2.
  • Their usual function is to strongly apply the lateral face 2 against the edges of the cylinders 1, by means of the plate 4. But they allow a slight decline of at least the portion of the lateral face 2 which is situated in their extension, when a parasitic solidification is interposed between it and one of the cylinders 1, without however the contact conditions between the remainder of the side face 2 and the cylinders 1 are strongly affected.
  • a plurality of tie rods 11, 11 ' are fixed to the rear face of the plate 4 and oriented substantially perpendicular to it.
  • the material of the tie rods must have good properties of resistance and dimensional stability at the temperatures encountered in this zone of the machine. It is recommended to use, for example, stainless steel with a low coefficient of expansion.
  • Figure 1 shows the installation in its initial state, at the start of casting, with a side face 2 having a thickness (e).
  • the springs which, in the example shown, constitute the pushing members 9, 9 ', 9 ", 9"', are in a state of compression corresponding to a distance ( d) between the plate 4 and the thrust plate 8.
  • the stops 13, 13 'of the tie rods 11, 11' are, in this initial state, at a distance (d ') from the rear face 14 of the push plate 8.
  • FIG. 2 represents the same installation at a later instant in the casting.
  • the position of the pushing device 6 has not varied, but the lateral face 2 has undergone progressive wear, due to its friction against the edges of the cylinders 1.
  • This wear has had the effect of increasing gradually the distance separating the thrust plate 8 and the plate 4 under the action of the springs 9, 9 ', 9 ", 9"' and the relaxation of their state of compression.
  • This distance, or at least its variations, can be estimated for example using displacement sensors integrated into the thrust members 9, 9 ', 9 ", 9"'.
  • the lateral face 2-plate 4 assembly can move back at least locally, this decline being all the more localized as this assembly has a certain flexibility and that the thrust members 9, 9 ', 9 ", 9"' are more numerous.
  • the stop 13, 13 'of one or more tie rods 11, 11' is no longer in contact with the thrust plate 8, and the thrust member (s) 9, 9 ", 9", 9 '' 'closest to the zone where the infiltration is resumed their function of firm application of the side face 2 against the cylinders 1.
  • This firm application lasts until the wear of the lateral face 2 is sufficiently pronounced so that the contact between the stops 13, 13 ′ and the thrust plate 8 is again made, and the conditions are thus found again. minimum friction desired. It is possible to choose to carry out this operation regularly, by imposing an average speed of movement of the order of 1 to 10 mm / h on the thrust plate 8. This speed of movement corresponds to the speed of wear that the we want to impose on the face lateral 2 in the absence of infiltration of solidified metal. This speed is notably lower than those which are usually imposed by conventional devices for applying the lateral faces against the cylinders, and which amount to a few tens of mm / h.
  • tie rods 13, 13 ′ for example three
  • a plurality of tie rods 13, 13 ′ distributed over the plate 4 over a zone of shape corresponding to that of the lateral face 2.
  • the invention is, moreover, perfectly compatible with the use of lateral faces 2 to which, as is known, an oscillation movement would be imparted in the plane of the flat faces of the cylinders 1, 1 '.
  • the device according to the invention can be supplemented by one or more position sensors providing a value representative, at least at a given instant, of the distance between the lateral face 2 and the cylinders 1. They make it possible to ensure that during the phases where wear of the side face 2 is sought, there is good contact between it and the cylindersl. On the other hand, in normal operation of the installation, it may be desired that this contact is not completely achieved, and endeavor to permanently maintain a clearance of 0.1 to 0.2 mm, sufficiently small to avoid leakage of molten metal but to eliminate wear on the side face 2 by friction. Only corrosion of liquid metal would then remain as the cause of wear.
