Definitions

  • the invention relates to a mold/chill tube having a double T-shaped inner and outer cross section in beam blank format which is encased in a water-guiding jacket adapted to its outer contour while forming a water gap.
  • the material temperatures in the chill wall result from the heat stresses occurring during continuous casting and the cooling conditions by the respective medium, which normally, in the form of water, flows from bottom to top in a water gap between a water-guiding jacket fitted to the outer contour of the chill tube and the outer surface of the chill tube, thereby taking up the heat encountered and carrying it off.
  • the removal of the heat with the aid of the cooling water is largely determined by the speed of the water in the water gap.
  • a chill tube having a double T-shaped inner and outer cross section in beam blank format, which is encased in a water-guiding jacket ( 12 ) adapted to its outer contour while forming a water gap ( 14 ), wherein the wall thickness (D) of chill tube ( 1 ) in the rounded transition regions ( 2 , 2 a , 2 b , 2 c , 2 d ) from middle crosspieces ( 4 ), which face each other head to head and are drawn in towards longitudinal axis ( 3 ), to the neighboring crosswise positioned flanges ( 5 ) is dimensioned at least partially smaller than in the remaining wall sections ( 6 , 7 ).
  • FIG. 1 shows in schematic perspective, a chill tube in beam blank format without a water-guiding jacket having lateral filler pieces.
  • FIG. 2 shows likewise in schematic perspective, the chill tube of FIG. 1 along with a separately shown filler piece.
  • FIG. 3 shows a top view of a chill tube without cover plate in the region of the lateral channels, but having a water-guiding jacket.
  • FIG. 4 shows a top view onto a chill tube according to further specific embodiments without cover plate and water-guiding jacket.
  • One option is that at the outside of the transition regions longitudinal hollow recesses are provided.
  • the curvature of the recesses in this case, may be largely adapted to the curvature of the inner surface of the transition regions.
  • the reduction in wall thickness, in the form of a hollow recess has the advantage that the outer surface of the chill tube is enlarged, so that an even better cooling effect may be achieved.
  • a plurality of longitudinal grooves running side by side are provided on the outside of the transition regions.
  • the cross section and/or depth of the grooves may be dimensioned to be equal or different in each transition region.
  • the cross section of the grooves may be rounded or angular, such as triangular.
  • the water-guiding jacket has a rectangular cross section, and, between the water-guiding jacket as well as the crosspieces and the flanges, filler pieces adjusted to the cross sectional region by the outer contour of the chill tube as well as the inner contour of the water-guiding jacket are incorporated.
  • the numeral 1 in FIGS. 1 through 4 denotes a chill tube having a double T-shaped inner and outer cross section in beam blank format. Chill tube 1 is used for the continuous casting of metals. In FIGS. 3 and 4, the curvature of chill tube 1 in the longitudinal direction is not shown.
  • wall thickness D of chill tube 1 in rounded transition regions 2 from middle crosspieces 4 , which face each other head to head and are drawn in towards longitudinal axis 3 , to the neighboring, crosswise positioned flanges 5 is dimensioned less than wall thickness D 1 in the remainder of wall sections 6 and 7 .
  • chill tube 1 On the peripheral side of chill tube 1 there is a water-guiding jacket 12 which may be seen only in FIG. 3, having an essentially rectangular cross section. Between water-guiding jacket 12 and outer surface 13 of chill tube 1 , a water gap 14 is formed through which cooling water is guided from bottom to top at a predefined water speed.
  • FIG. 4 shows four different specific embodiments of how the reduction in wall thickness of chill tube 1 may also be implemented.
  • transition regions 2 a , 2 b , 2 c on the outer side, several longitudinal grooves 18 , 18 a , 18 b are provided which run next to one another. Whereas in transition region 2 a grooves 18 have a triangular cross section, grooves 18 a , 18 b in transition regions 2 b , 2 c have rounded bottoms. In this context, grooves 18 b in transition region 2 c have a greater depth than grooves 18 a in transition region 2 b.
  • transition region 2 d reduction in wall thickness is implemented by bores 19 . These bores 19 lie closer to outer surface 13 of chill tube 1 than to inner surface 11 .
  • Both grooves 18 , 18 a , 18 b and bores 19 extend, as do recesses 8 , only in the height range of the bath level.
