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.
  • French patent application FR9408319 brings an improvement to this procedure and those who derive from it by providing means to slightly deform the lateral faces by modulating the pressure applied to their different areas.
  • temporary or permanent inequalities in the forces exerted on the different parts of the lateral faces by the cylinders can occur, for example, in the case of parasitic solidification of metal seeped between the side face and a cylinder, or when both sides of the cylinders against which the side face is applied are not perfectly coplanar and orthogonal to the axes of the cylinders.
  • Document EP-A-0 588 743 proposes to lubricate the interface between the face side and the cylinder by means of a bar of self-lubricating material crossing the lateral face, permanently maintaining a slight clearance between the lateral face and the cylinder in its area of application. For this purpose, it must necessarily be permanently applied against the cylinder and overflowing from the side face.
  • 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 connected to said device thrust and integral with the lateral face, characterized in that said plate comprises at at least two pads movable when ordered in a direction parallel to the axes cylinders by devices capable of applying each of said pads against a edge of one of the cylinders without causing it to overflow relative to said lateral face.
  • the invention consists in equipping the support means side faces of at least two friction pads movable on command can each rest on one of the cylinders. These pads allow to regulate precisely the loss of material due to wear of the lateral face at a very low value when the contact surfaces between the side face and the edges of the cylinders are perfectly regular.
  • we normally aim for the front side of each skate is kept permanently aligned with the front face of the face lateral, or very slightly set back from it. If the skates are aligned on the face lateral, they are the ones who assume the friction force between the cylinders and the face lateral, whose wear by friction becomes theoretically zero. If they are placed slightly behind the side face, it is only this which will rub against the cylinders.
  • Figure 1 shows a side of a casting machine between two rolls 1, 1 '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 so similar.
  • the casting space defined by the two cylinders 1, 1 ' is closed laterally by a side face 2 made of refractory material, the front face of which is applied against edges 3 of cylinders 1, 1 '.
  • the side face 2 is fixed on a plate 4 which is in one material such as 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 cylinders 1, 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, 1 '.
  • a device thrust 6 such as a jack, comprising a rod 7 movable on control, always in the same direction parallel to the axes of the cylinders 1, 1 '.
  • this rod 7 acts directly on the plate 4, and its position, combined with that of the carriage 5, makes it possible to adjust the pressing force exerted by the side face 2 on the cylinders 1, 1 '.
  • the rod 7 attacks a thrust plate 8, itself connected to the plate 4 by a set of thrust members, 9, 9 ', 9 ", 9"' such as springs or piloted cylinders.
  • thrust members 9, 9 ', 9 ", 9"' such as springs or piloted cylinders.
  • These organs are distributed over an area whose shape corresponds to that of the side face 2. They have the function of authorizing a slight retreat of a portion of the lateral face 2 when a parasitic solidification is interposed between it and one of the cylinders 1, 1 ', without however the contact conditions between the rest of the face side 2 and the cylinders are affected.
  • the plate 4 supporting the side face 2 carries four pads 10, 10 ', 10 ", 10"'.
  • These pads 10, 10 ', 10 ", 10"' are each equipped with a device 11, 11 'which can move them on command, gradually or jerky, to give them the possibility of either coming to bear. on any part of the edge 3 of one of the cylinders 1, 1 ', or to move away from this cylinder.
  • Figure 2 there is shown in phantom the trace of the peripheries of the cylinders 1, 1 ', in order to locate the locations of the pads 10, 10', 10 ", 10"'relative to the cylinders 1, 1' and the side face 2.
  • the pads 10, 10 " are located in the upper part of the plate 4 and can bear on the edges of the edges 3 of the cylinders 1, 1 'just above the side face 2.
  • the pads 10 ', 10 "' are located in the lower part of the plate 4 and bear on the cylinders 1, 1 'next to the side face 2 and near the neck 12, that is to say of the area where the gap between the cylinders 1, 1 ′ is the smallest. It is understood that the locations of the pads 10, 10 ', 10 " , 10"' as they are described and shown are only examples of implementation of the invention. Other locations could be envisaged, and their choice depends in particular on the configuration of the plate 4.
  • the devices for moving the pads 10, 10 ', 10 ", 10”' can be constituted by any electric or hydraulic actuators, for example cylinders, screws, rack and pinion devices, etc.
  • These pads 10, 10 ', 10 ", 10"' can, as shown, have a planar contact surface with the edges 3 of the cylinders 1, 1 '.
  • they also preferably comprise means not shown ensuring the lubrication of this contact surface, for example by injecting oil or a powder of a solid lubricant such as boron nitride. This limits wear by friction of both the cylinders 1, 1 'and the pads 10, 10', 10 ", 10"'.
  • these pads 10, 10 ', 10 ", 10"' can be constituted by a roller or a roller, in which case it is no longer useful to provide a lubrication device.
  • these variants have the advantage, compared to the pads having a planar contact surface with the cylinder 1, 1 ', of being less sensitive to the dirt which may be present on the edges 3 of cylinders 1, 1 ', thanks to their reduced contact surface.
  • each plate 4 it is also possible to equip each plate 4 only with two pads, rubbing each on a different cylinder 1, 1 ′, and preferably arranged in the vicinity of the upper part of the lateral face 4, for example at the location of the pads 10, 10 "in Figure 2.
  • the lubrication systems of the pads 10, 10 "contribute to the lubrication of the interfaces between the cylinders 1, 1 'and the face lateral 2, because the edges of the cylinders 1, 1 ′ against which they are supported go, immediately after, come into contact with the side face 2. This is favorable for a reduced wear on the side face 2.
  • Another variant of the invention consists in using pads 10, 10 ', 10 ", 10"' (or at least some of them) in a self-lubricating material, such as nitride of boron.
  • a self-lubricating material such as nitride of boron.
  • 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 '.
