Definitions

  • the present invention relates to an ingot mold for casting ultra thin slabs to be used, in particular, in a manufacturing plant for the manufacture of metal strips.
  • ingot molds used for casting metal strips, in particular of steel, are known in the state of the art.
  • An example of a mold for the continuous casting of thin slabs is disclosed in US 5520242 .
  • Another example is disclosed in US 2004/050529 .
  • ingot molds can produce a slab which is subjected to a number of thickness reductions, sometimes associated with surface treatments and machining, depending on the process used.
  • the metal strip machinery will be particularly long because the slabs produced by ingot molds of the known type, also called crystallizers, have considerable thicknesses when coming out of the ingot mold, hence they will require numerous intermediate devices which will increase the total length of the machinery to a great extent.
  • One main purpose of the present invention is to achieve an ingot mold for casting ultra thin slabs to be used, for instance, in a manufacturing plant for the manufacture of metal strips, in particular steel strips.
  • Another purpose of the ingot mold, according to the invention is to produce thin thicknesses, about 20mm, at high casting speeds, up to 16 m/min, thereby ensuring good quality inside the slab.
  • the present invention intends to solve the foregoing problems by achieving an ingot mold for casting ultra thin (20 - 50 mm) steel slabs, with casting speed between 6 and 16m/min, thus defining a longitudinal plane of symmetry and a cross-sectional plane of symmetry, reciprocally orthogonal, comprising a passing cavity with an entrance section and an exit section of the steel, the cavity surface consisting of two first walls - arranged reciprocally facing two opposite sides of the longitudinal plane of symmetry and with respective concavities facing the longitudinal plane of symmetry - and two second narrow rectangular walls located parallel to the cross-sectional plane of symmetry, wherein the first and second walls form four longitudinal corners in the reciprocal connecting areas and where - in a section located on a cross-sectional plane perpendicular to the longitudinal and cross-sectional planes of symmetry - the respective concavities are in the shape of a semi-circular arc of a predetermined radius whereby the straight line tangent to the semi-circular arc intersecting the relative corner forms an
  • the ingot mold by using the ingot mold it is possible to cast a slab with a thickness much smaller than the thickness that can be achieved with known ingot molds, between 20-50mm, yet helping maintain a certain length of liquid core downstream of the exit section of the ingot mold, and wherein the core remains liquid even in the zones nearest the furthermost side parts.
  • the slab when the slab is subjected to the liquid core pre-rolling, it will be possible to obtain a refinement of the internal structure by reducing central porosity as well as the segregation phenomenon.
  • the strip obtained at the end of the passage throughout the whole hot-rolling and casting line is already at its final thickness and ready to be used, without a need to carry out an additional treatment in a cold-rolling line.
  • the surface of said cavity is defined by two wide walls 4, 5, reciprocally arranged and facing out on opposite sides relative to the plane of symmetry X, and by two narrow walls 6, 7 generally flat, rectangular and parallel, arranged at a right angle relative to the plane of symmetry X.
  • the wide and narrow walls form four longitudinal corners in their connecting zones.
  • the wide walls 4,5 are concave.
  • the concavity faces the longitudinal plane of symmetry X.
  • the concavity of the walls 4,5 is such as to define a section of the lenticularshaped basin.
  • the range of the angle ⁇ ensures the presence of low stresses and limited deformations on the skin in the narrow walls zone and therefore the possibilities of tearing the skin are minimal, resulting in spillage of the molten steel, known as the "break-out" phenomenon.
  • the ingot mold, according to the invention - wherein "I” is the distance between the narrow walls and “f” is the camber of the concave walls 4, 5 of the basin - advantageously has the following values in the entrance section:
  • the ingot mold or lenticular crystallizer of the invention prevents the edges from excessively pivoting during pre-rolling, thereby avoiding cracks or other flaws in these zones.
  • the internal structure of such ingot mold ensures a suitable volume of molten steel, thus when the slab comes out, there will still be a certain length of the liquid core.
  • the lenticular shape maintains the liquid core even when very close to the furthermost sides of the slab, thereby making a subsequent liquid core pre-rolling possible, the so-called "soft reduction", for the cast slab.
  • the volume of molten steel inside the ingot mold is enough to dampen the fluid mechanical turbulence generated by the unloading device.
  • a first advantageous variation of the ingot mold includes an entrance section for the steel section larger than the exit section located near the bottom end of the ingot mold.
  • the radius of curvature of the semi-circular arc on the cross-sectional plane has a linearly increasing value between the entrance section and a predetermined intermediate section, which corresponds to the terminal section of the casting chamber before the exit section of the steel.
  • the ingot mold of this invention includes an inclination of the walls of said casting chamber, converging towards said intermediate section, determined by an angle ⁇ (0°-7°) wherein said angle ⁇ is measured according to the plane of symmetry z-y.
  • the bottom end of the ingot mold advantageously includes a portion 10 with a parallel-generating line, the length of which has been predetermined and shaped as the basin to allow the insertion and the removal of the dummy bar inside of it, thus used for starting the continuous casting process.
  • a second variation of the ingot mold according to the invention includes entrance and exit sections of equal dimensions, as described in the section in Fig. 3a .
  • the radius of curvature of the semi-circular arc on the cross-sectional plane has the same value in each point of the longitudinal extension of the cavity between the entrance section and the exit section of the steel.
  • the narrow walls 6, 7 can change their tapering shape. More precisely, they can be moved inward towards the exit section of the steel so as to reduce the width of the exit section, thus avoiding shrinkage problems during the solidification in the ingot mold.
  • the casting of very thin slabs, through the ingot mold of the invention, allows for the possibility to create a starting product, i.e. the slab thereof, with a thickness which is already very close to that of the finished product, namely the strip.
  • the thickness of these thin slabs, when exiting is between 20 and 50 mm and their casting speed is between 6 and 16 m/min.
  • the typical convex shape of the slab in other words the central swelling at the exit of the ingot mold, is cancelled, that is flattened, through the use of rollers placed at the foot of the ingot mold and appropriately shaped, thus performing the liquid core pre-rolling.
