Definitions

  • the invention relates to the continuous casting of metals. More specifically, it concerns the devices for lateral containment of liquid metal in the ingot molds of thin strip continuous casting machines, the casting space of which is limited by the side surfaces close to two cylinders with horizontal axes, energetically internally cooled and rotated in opposite directions.
  • 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 higher than what would be strictly necessary for the smooth running of the casting.
  • the invention relates to a device for supporting a lateral face of a continuous casting installation between cylinders of thin metal products of the type with two cooled cylinders with horizontal axes, two side faces applied against the edges of the rolls, said support device comprising a carriage movable on command in a direction parallel to the axes of the cylinders, a pushing device carried by said carriage, and a plate integral with the face lateral, connected to said pushing device via a pushing plate and thrust members bearing on said thrust plate and said plate, (see: EP-A-0698433).
  • Said plate comprises at least one tie rod 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 push plate.
  • the plate supporting the small face is equipped with one or more tie rods passing through the thrust plate, and the free ends can abut against the rear face of the thrust plate.
  • the thrust members which normally tend to move the plate away from the push plate to apply the side face against the cylinders causing its wear, see their action limited when this wear has become sufficiently pronounced so that this abutment is achieved. There is then only one minimal friction between the side face and the cylinders, and wear on the side face 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 equipped in the same way.
  • the casting space defined by the two cylinders is closed laterally by a side face 2 of refractory material whose front face is applied against the edges 3 of the cylinders 1.
  • the lateral face 2 is fixed by its face rear on 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.
  • Displacement and bearing force on the cylinders 1 of the side face 2 are controlled by an assembly which acts on the plate 4 and which will be described in more detail detail.
  • it comprises a carriage 5 movable to control according to a direction parallel to the cylinder axes 1.
  • a device for thrust 6 such as a jack (or group of jacks) controlled by pressure or position, comprising a rod 7 which can be moved 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 jacks piloted, exerting their force on the rear face 10 of the plate 4.
  • thrust members 9, 9 ', 9' ', 9' '' such as springs or jacks piloted, 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 side face 2 against the edges of the cylinders 1, via the plate 4.
  • a plurality tie rods 11, 11 ′ are fixed to the rear face of the plate 4 and oriented substantially perpendicular to it. These tie rods 11, 11 ′ pass through the thrust plate 8 thanks to passages 12, 12 'which are provided for this purpose, and their free end is equipped a stop 13, 13 'of dimensions greater than those of the passages 12, 12'.
  • the lengths of tie rods 11, 11 ' are chosen so that the stops 13, 13' can come to bear against the rear face 14 of the thrust plate 8 before the members 9, 9 ', 9' ', 9' ' thrust have reached their maximum possible extension.
  • the material tie rods must have good strength and stability properties dimensional to the temperatures encountered in this area of the machine. We recommend using, for example, stainless steel with a low coefficient of dilation.
  • FIG. 1 represents the installation in its initial state, at the start of the casting, with a side face 2 having a thickness (e).
  • the springs which, in the example shown, constitute the thrust 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 ' 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 changed, but the face lateral 2 underwent progressive wear, due to its friction against the edges of cylinders 1.
  • This wear gradually increased the distance between the thrust plate 8 and the plate 4 under the action of the springs 9, 9 ', 9' ', 9' '' and the loosening of their state of compression.
  • This distance can be estimated for example using displacement sensors integrated into the organs 9, 9 ', 9' ', 9' '' thrust.
  • the side face 2-plate assembly 4 can retreat at least locally, this decline being all the more localized as this together has a certain flexibility and that the pushing 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 push plate 8, and the push member (s) 9, 9 '', 9 '', 9 '' 'closest to the infiltration area resume their function firm application of the side face 2 against the cylinders 1.
  • tie rods 13, 13 ' for example three
  • the side face 2-plate assembly 4 presents a certain flexibility or possibilities of travel in the three dimensions, it is possible to better take into account the local setbacks of the face lateral 2, as well as the misalignment of the edges of the cylinders 1 one on the other.
  • the invention is, moreover, perfectly compatible with the use of faces side 2 which, as it is known, would give an oscillating movement 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 sensors position providing a value representative, at least at a given time, of the distance between the side 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, during normal operation of the installation, may wish this contact not to be fully realized, and endeavor to maintain permanent play of 0.1 to 0.2 mm, small enough to prevent metal leakage liquid but making it possible to eliminate wear on the side face 2 by friction. Alone Corrosion by liquid metal would then remain as a cause of wear.
