Definitions

  • the invention relates to a mold for the continuous casting of pre-profiles consisting of a web and two flanges for carrier rolling with two cooled side walls reaching over the web and the flanges and with adjustable arranged between the side walls, determining the flange thickness, cooling end walls.
  • the molten steel is introduced into the mold from an intermediate container via a dip tube in the area of the web.
  • the end walls of the mold between the side walls can be adjusted to change the flange thickness of the preliminary profile. Changing the web height and web thickness is not possible with this mold.
  • Another disadvantage of the known mold shape is that the strand can become jammed as a result of the shrinkage of the strand inside the mold.
  • the object of the invention is to provide a continuous casting mold, of the aforementioned type, with which, with a simple design, preliminary profiles for the carrier rolling can be cast with a web height, web thickness and flange thickness which can be set independently of one another.
  • preliminary profiles for the carrier rolling can be cast with a web height, web thickness and flange thickness which can be set independently of one another.
  • the casting of profiles close to final dimensions with a uniformly good structure should be made possible.
  • each side wall of the mold has a straight and an outwardly angled end region, the end walls are arranged between in each case a straight and an angled opposite end region and at least one side wall is adjustable transversely to the casting direction in the direction of its flat surface with respect to the other side wall and the distance between the end side walls is variable.
  • the continuous casting mold created in this way can be easily and quickly adjusted independently of one another for casting beam pre-profiles of different web heights, web thicknesses and flange thicknesses, making casting of small production quantities close to the final dimensions economical.
  • the special design of the mold prevents the pre-profile from jamming due to its shrinkage within the mold.
  • the side walls of the mold in the web area have an enlarged casting area which is limited to only part of the mold height.
  • the melt is introduced through a dip tube down to the bath level and the casting metal is well distributed to the end areas.
  • the invention is further developed as follows.
  • the pouring area merges into the lower format area with a web thickness of 40 to 90 mm.
  • the pouring area merges into the end area of the side walls at least on one side.
  • Opposing end areas of the side walls run at an angle of 60 to 85 °.
  • the end walls of the mold are bulged inwards.
  • the preliminary profile is guided below the mold in the web and flange area and, after solidification, is subjected to a bending and straightening process.
  • support plates or support rollers corresponding to the shape of the web and flange areas of the preliminary profile are arranged below the continuous casting mold.
  • a continuous casting mold for casting pre-profiles consists of two side walls 1, 2 and two end walls 3, 4 arranged between the side walls 1, 2.
  • the side walls 1 , 2 have an angled and a straight end region 1a, 1b, 2a, 2b, which form the space for the flanges 6, 7 of the preliminary profile 5 in an opposite arrangement with the end walls 3, 4 arranged between them.
  • the end walls 3, 4 are each provided with an inwardly extending projection 8 on the inside of the mold, whereby the flanges 6, 7 are preformed for subsequent rolling.
  • the central region of the side walls 1, 2 which forms the web 9 of the preliminary profile 5 form an enlarged pouring region 11 for receiving an immersion pouring tube 10 for introducing the melt into the upper region which merges into the lower format region 12 in an arc shape.
  • the pouring area 11 ends in each case at the angled end area 1a, 2a of the side walls 1, 2 (FIGS. 1 to 3).
  • the mold is directly followed by several support rollers 13, 14, the arrangement of which is associated with the web 9 and the flanges 6, 7 of the preliminary profile 5, in particular from FIG. 4.
  • Water spray nozzles 15 for strand cooling are arranged between the support rollers 13, 14.
  • the side walls 1, 2 and the end walls 3, 4 of the mold are provided with cooling channels 16.
  • FIGS. 6 and 7 show how the side walls 1, 2 of the mold can be adjusted parallel to one another transversely to the casting direction in the direction of the arrows 17, 18. In this way, the height of the web 9 of the preliminary profile 5 can be changed.
  • FIG. 8 A change in the thickness of the web 9 compared to the original setting shown in FIG. 6 is shown in FIG. 8.
  • the side wall 2 of the mold is adjusted in the direction of the arrow 19 and the end walls 3, 4 accordingly in the direction of the arrows 20, 21.
  • the cast pre-profile 5 according to FIG. 5 is bent from the vertical into the horizontal for directing and straightened again.
  • the flanges 6, 7 lying on one side and asymmetrically to the neutral fiber 22 of the web 9 are displaced in the direction of the neutral fiber 22 and thus into the position 6a, 7a. This effect simplifies the subsequent rolling process.
  • the invention is not restricted to the exemplary embodiment shown.
