Definitions

  • the invention relates to the continuous casting of metals, and more particularly installations for casting metal strips, in particular steel, of a few mm thick, between two counter-rotating cylinders with horizontal axes, internally cooled.
  • the object of the invention is to propose a lateral face configuration which avoids that the degradation of the positive insert has harmful consequences on the quality of the tape and the flow of the casting.
  • the invention relates to a lateral face for closing off the space.
  • casting of a continuous casting installation of metal strips between two cylinders close counter-rotating with horizontal axes of the type having a lower part in a first refractory material, of high hardness, in the zone where said lower part is in contact with the edges of said cylinders, or of liquid metal likely to be in progress solidification, or an edge of the solidified strip (as described for example in document EP 0 432 073), characterized in that said part lower comprises, on its face intended to be turned in the direction of the pouring space, a recess filled with a refractory material.
  • said refractory material enclosed by said recess is a material having a lower hardness than said first refractory material and high heat insulating properties.
  • the invention consists in giving the lateral face in its lowest part a bilayer structure, designed so that when the stresses exerted on the upper layer by the solidified metal become significant, it degrades without this degradation being able to extend to higher levels of the face lateral. This gives us the opportunity to control the unfolding of a phenomenon which, if occurred out of control, could lead to serious disruption of the operation of the casting machine.
  • the prior art casting installation between cylinders shown in the Figures 1 and 2 comprises, conventionally, two cylinders 1, 1 'close to horizontal axes whose cylindrical side walls 2, 2 'are energetically cooled internally. They are rotated in opposite directions by known means not shown.
  • the space of casting, in which the liquid steel 3 is introduced by a nozzle (not shown) connected to a container such as a pocket or a distributor, is delimited by the side walls 2, 2 ' cylinders 1, 1 'and by side faces 4, 4' made of refractory material (the side face 4 ' is not shown in Figure 1 to make visible the constitution of the side face 4).
  • the elements made of refractory material of the faces side 4, 4 'of the example shown have two parts. Their portions 8, 9 which are in contact with the edges 5, 5 'of the cylinders 1, 1' or in the vicinity of the zones where this contact, as well as all of their lower part 10 over a height of approximately 150 mm, are made of a first material, of high hardness and having great qualities of resistance to corrosion by liquid metal.
  • the central part 11 remaining of the faces side 4, 4 ' is made of a material preferably having good properties thermal insulation and may be of a lower hardness than said first material.
  • FIG 2a shows the installation at the very start of casting, while the side faces 4, 4 ' are new and have facing the edges 5, 5 'of the cylinders, the liquid steel 3 and the strip 7 a uniformly flat front face.
  • Figure 2b shows the same installation at a later stage of casting, while the side faces 4, 4 'have already undergone a significant wear.
  • the central part 11 has been consumed at a depth "e” relatively significant by corrosion and mechanical wear in contact with liquid steel 3 in movement.
  • the hard material portions 8, 9 and 10 were worn by friction on a depth "x" in their zones which face the edges 5, 5 'of the cylinders 1, 1', while their zones not subjected to the friction of the edges 5, 5 ′ have, in the ideal case shown, no wear.
  • this positive insert 12 is subjected on its front part to intense stresses on the part of the steel 3 which may be, in its vicinity, already in a state partially solidified. Its lateral parts are likewise subject to contact with the skins. of solidified metal against the cylinders. Consequently, under the effect of these various stresses, there is a periodic and uncontrolled rupture of the lower part of the positive insert 12, along a generally irregular line 13.
  • this rupture extends relatively deep into the refractory, to the point of destroying sealing the casting space and leaving the possibility for liquid steel 14 to escape out of this space by a crevice 15. This is, in particular, the case if the rupture propagates upwards from positive insert 12, therefore towards regions where the metal which borders the lateral face 4, 4 ′ is entirely in the liquid state. If this steel 14 gets immediately solidifies between the side face 4 and the edge 5, it causes the face to recede lateral 4 and contributes a little more to its deterioration, as well as to that of edge 5. If the breach 15 opens to the outside, the liquid steel 14 can flow out of the machine casting with all the risks that this entails for the installation and the personnel.
  • the longitudinal sections in depth of the recess 16 and of the refractory 17 which fills it have the shape of a rectangular trapezoid whose point is oriented towards the part upper part of the pouring space, and the large base of which is situated opposite this same casting space.
  • This large base extends over a height "h 1 " above the level of the neck 6, "h 1 " being equal to, for example, 70 mm (this value does not include the part of the small face intended for extend under the neck 6 after its installation).
  • the small base of the trapezoid, located at the rear of the recess extends over a height "h 2 " above the level of the neck 6, equal, for example, to 55 mm.
  • the recess 16 has a maximum depth "p" equal to, for example, 15 mm. "p" must be greater than the maximum tolerated value of the wear of the parts 8, 9, 10 of hard material of the lateral face 4, 4 ′, so that the refractory 17 which fills it can play its role during the assembly of casting.
  • Figure 4 shows in operation a casting installation between cylinders equipped with side faces 4, 4 'according to the invention, under the same conditions as the installation shown in Figure 2b.
  • a positive insert 12 of maximum thickness "x" at the levels where the side faces 4, 4 'are formed by the hard refractory 10.
  • the parts of the side faces 4, 4 'According to the invention which face the strip 7 or areas where the metal 3 is in the partially solidified state undergo wear the quantitative importance of which is a function of the stresses to which they are subjected. These stresses tend to increase with the solid fraction of the metal 3, and consequently, the penetration depth of the positive insert 12 decreases as one approaches the neck 6.
  • the positive insert 12 can possibly, as shown in Figure 4, be fully consumed.
  • the refractory 17 lining the recess 16 of each lateral face 4, 4 ′ according to the invention does not have a very high hardness, its wear is regular and we do not normally observe the presence of rupture lines of tormented shapes and random as line 13 in Figure 2b.
  • this rupture would necessarily stop at the limits of the recess 16.
  • the recess 16 has a section longitudinal trapezoidal shape. We therefore aim to ensure that, once the consumption of refractory 17 primed, the hard refractory 10 exposed to the liquid metal 3 or partially solidified a beveled surface offering only a relatively limited grip mechanical wear. A rectangular section for this recess 16 would leave after wear of the refractory 17 a hard refractory 10 having a sharp angle making it more sensitive to wear and more prone to sudden and irregular ruptures. That said, such a section rectangular of the recess 16 would essentially remain within the scope of the invention such that defined by the appended claims.
  • the recess 16 has a section longitudinal in the shape of a right triangle.
  • the invention can easily be adapted to lateral faces which would have shapes different from the one shown in the previous example.
