Definitions

  • the subject of the present invention is a device for continuous casting of liquid metal, for example steel, between two parallel cylinders, of the type comprising plates secured against the front faces of the cylinders to close off the ends of the defined casting space. by the cylinders.
  • the object of the invention is therefore to produce a device provided with means making it possible to avoid these infiltrations of liquid metal into the joints between the lateral faces and the front faces of the cylinders.
  • each front face of a cylinder is equipped with an endless flexible band, bearing, on the one hand on the cylinder at the junction of its front face and its cylindrical surface, and on the other hand on a curved surface of the associated obturator plate, this curved surface being an extension of the cylindrical surface of the cylinder, to ensure sealing between the obturator plate and the front faces of the cylinders.
  • a clearance called a "negative insert” is provided in the face of each obturating plate, facing the casting space between the cylinders, thus extended by this release.
  • the release thus allows the creation of said curved surfaces of the shutter plate.
  • Each endless band can be guided in a groove formed on the cylinder at the junction of its front face and its cylindrical surface and / or in a second groove formed in said curved surface of the obturator plate.
  • the endless bands can be driven either by a motor or by the cylinders, for example by pins formed thereon.
  • the device shown in Figs 1 to 5 is intended for the continuous casting of liquid metal between two parallel cylinders 1 and 2, delimiting between them a space 3 for casting flat products.
  • This space 3 is closed by plates 4 held in abutment against the front faces 1a, 2a of the cylinders 1, 2, by means known per se and not shown.
  • Each front face 1a, 2a is equipped with a flexible band 5, 5 ′ respective endless, bearing, on the one hand on the corresponding cylinder 1, 2 at the junction of its front face 1a, 2a and its cylindrical surface 1b, 2b, and on the other hand on the face opposite the associated shutter plate 4.
  • a clearance 6 the width 1 in its central zone being equal to the width of the the casting space 3 is formed in the face of the plate 4 facing the cylinders 1, 2.
  • the convex edges 6a of the clearance 6, called “negative insert” have a radius of curvature equal to that of the cylinders 1 and 2 , and are placed opposite the edges of the latter.
  • the width of the strips 5 and 5 ′ is determined so that they cover the seals 10, bearing on either side of them on corresponding surfaces 6a of the plate 4 and 11 of the ends of the cylinders 1, 2
  • the surfaces 11 form the cylindrical recesses 8 formed at the ends of the cylinders 1 and 2 facing the surfaces 6a.
  • the surfaces 6a constitute the recesses 6b of the plate 4, beyond which an additional clearance 6 ′ is provided, in a direction parallel to the axes of the cylinders 1, 2.
  • This clearance 6 ′ can serve, for example, as a support for a refractory lining, and its bottom 6c can be inclined on a vertical plane.
  • the strips 5, 5 ′ pass over idler and tension rollers 9, 17, 14 (Fig. 1), the lower rollers 12 being judiciously arranged so that the strips 5, 5 ′ do not remain in contact with the metal cast at below the plates 4.
  • the bands 5, 5 ′ can be driven, either by a motor not shown, at the same speed of rotation as the cylinders 1 and 2, or by the latter, for example by means of pins 15 formed on the cylinders (Fig. 3).
  • Fig.5 only includes the idler rollers 9, 14, so that the endless bands 5, 5 ′ are wound on half the circumference of the surfaces 11 of the cylinders 1, 2, the surfaces d 'support 6a having of course the same radius of curvature as the cylinders.
  • Means are advantageously provided for cooling the endless belts 5, 5 ′, for example not shown nozzles for spraying water, placed on each side of the device.
  • the invention thus achieves the use of sealing strips 5, 5 ′ of a few millimeters in width, at the intersection between the cylinders 1, 2 and the negative inserts 6, and which travel at the same speed as the cylinders .
  • the recesses 8 are eliminated, and the strips 5, 5 ′ bear directly on the cylindrical surfaces 1b, 2b.
