Definitions

  • the invention relates to a mold for the continuous casting of metal with a cooled Broad side walls and narrow side walls, in one below the other Horizons funnel-shaped in the pouring direction to the format of the cast strand itself tapering pouring area, which is characterized by curved contour areas of the Broad side walls (1, 1 ') is formed.
  • the dimensions of the pouring area are essentially determined by the cross section of the strand to be cast, the dimensions of the pouring tube and its Immersion depth in the melt determined.
  • the funnel-shaped formation of the pouring area is due to the effort to pour as thin a strand as possible, which after leaving the casting machine cut into slabs and after passing through an oven at least partial use of the rolling heat is rolled out.
  • the document DE 44 35 218 A1 describes a mold for the continuous casting of Thin slabs or steel strips.
  • the production is simplified, the surface of the cast strand is improved and the strand breakage risk diminishes when a mold wall of a first broad side wall is flat and at an angle a of 2 to 10 ° to the vertical, and one Form wall of the second broad side wall opposite to the inclination of the flat shape wall has widening curvature.
  • Document DE 197 10 791 A1 describes an oscillating mold for casting of preferably thin slab and slab formats in the dimensional range from 40 to 150 x 500 to 3300 mm with casting speeds of up to 10 m / min using mold powder.
  • the mold with immersion nozzle shows in Pouring direction on symmetrical concave, flat broad side plates, some of which center symmetrically superimposed by a funnel, the one uniform heat flow over the entire mold width at a given Ensures immersion mold.
  • These mold features in conjunction with free Selectable dip pouring features make it possible to have a maximum desired Casting performance, flawless slab surfaces even at high casting speeds and crack-sensitive steel grades and a large width adjustment range from e.g. 500 to 1800 mm can be realized with one mold can.
  • the document DE 44 36 990 C1 relates to a dip tube for supplying Melting steel into a continuous casting mold with long and short sides.
  • a submerged pouring tube that has the kinetic in a structurally simple construction Energy of the molten steel in the area between that immersed in the melt Dismantles section of the immersion pouring tube and the long sides of the mold and can be specified on the flow formation of the liquid steel in the mold in the area of the bath surface
  • the invention proposes that the outer tube wall of the immersion pouring tube in the long side of the mold facing longitudinal area has a shape that is independent from the immersion depth of the immersion pouring tube into the one located in the continuous casting mold Melt has an almost constant distance to the long sides of the mold.
  • the outer tube wall of the immersion pouring tube in their broad-side areas facing the mold broadsides are shaped elements has that of the horizontal flow of the molten steel and that on it floating casting powder provides minimal resistance.
  • the invention has for its object a mold in the preamble specify according to claim 1 type, by which the flow conditions the melt in the pouring area can be improved, that due to the reduction in bath level fluctuations and turbulence on Bath level a significant minimization of the defect of the slab surface is achieved with non-metallic inclusions.
  • the funnel-shaped pouring area is designed such that at least a horizon a line A-A ', which points with maximum funnel openings the broad side walls connects, not perpendicular, but diagonally to Line x-x runs, which also connects the centers of the narrow side walls.
  • the funnel-shaped pouring area can be formed that the line y-y, which is the two points with the maximum funnel width connects, does not run perpendicular to the line x-x, which the two centers of the Narrow sides connects.
  • the funnel-shaped pouring area be shaped such that the points of the largest funnel width A-A 'horizontally around a distance range are shifted from each other.
  • the invention provides that the outer contour in the bathroom mirror area the immersion pouring tube represents a parallelogram with rounded corners, which supports the rotating movement of the melt around the dip tube.
  • the continuous casting mold according to the overview of FIGS. 1, 2 and 3 each has two opposite broad side walls 1, 1 'and two between the Wide side walls clamped narrow side walls 2, 2 '.
  • the broad side walls 1, 1 ' have a funnel-shaped pouring area curved in the area of their upper edge on the narrow sides and in the casting direction on the format of the cast strand is reduced.
  • an embodiment of the invention provides that at a height section of the mold, the horizontal contour of the funnel-shaped Pouring area in each broad side plate 1, 1 'by two different curved contour sections 3, 4 and 3 ', 4' with different lengths K, L are formed is, the unequal contour sections 3, 4 and 3 ', 4' in the points of maximum funnel width A or A 'are connected.
  • Essential characteristic of this Mold is that line y-y, which is the two points of the maximum funnel width A, A 'connects, does not run perpendicular to the line x-x, which is the center points that connects narrow sides.
  • Fig. 2 shows that the inventive design of the funnel-shaped pouring area is also possible if according to the state of the art Line z-z, which connects the two points of the maximum funnel width A, A ', runs perpendicular to the line x-x, which connects the centers of the narrow sides. According to the invention, it is only necessary that the points A, A 'in each case delimit two different contour sections 3, 4 and 3 ', 4' from each other, which have a different curvature and different lengths K, L.
  • the configuration of the funnel area shown in FIGS. 1 and 2 can be used during the casting of comparatively soft carbon steels and silicon alloys Steels are preferred.
  • the cross section of the mold space is designed in such a way that a rotating movement of the melt around the immersion nozzle is stimulated becomes.
  • the configuration according to the invention proves to be particularly advantageous here of the mold cavity in cooperation with the invention shown in Fig. 1 Design of the outer contour 6-7-6'-7 'of the immersion nozzle 5 with inclined webs or wall areas 6, 6 'through which the rotating Movement of the melt around the immersion pouring tube 5 is increasingly stimulated.
